Station Checks and Logger

We are all bound by CRTC law that logger tapes must be made 24/7 and provided to the CRTC for verification if requested. Failure to do so could result in the station losing its license.
You are to check the stations by listening to the air feed. Send out an email to engineering report every 15 minutes.
A clear AM feed can be heard at link for the TX site.

Logger (

Logger checks are to be done every half hour sent with your email to engineering, IF there is something wrong with the logger bring it to I.Ts attentions as well as engineering.
You must check the following logger feeds:
  • CIAO File Size 5.15MB
  • CIRR(Proud) File Size 6.87MB
  • CIDC File Size 13.73MB
  • CKHZ & CKHY (Halifax) File Size 13.73MB
  • CKDX File Size 13.73MB
  • CJWL (Ottawa) File Size 13.73MB
  • CKHK (Hawkesbury) File Size 13.73MB
  • CKPC AM & FM (Brantford) File Size 13.73MB
Even if the file size looks fine still listen to the audio of it, because you never know.
There may be a delay in the logger interface reporting files. They are split at 15min intervals, so it may appear as though the odd file doesn't appear. If we go more than an hour without a new file being created Start by Emailing IT and Engineering Just call it LOGGER state in the body what is wrong and make it high importance - then after not response for a half hour - that is the time to start waking people up.
You are pulling this info across the internet there may be times when our DSL connections at the remote locations are slow. If you can't get on wait a few minutes, refresh your browser and try again.
If logger is down or producing silence for more than 30 mins call I.T and send a fault report.
When you first load up the logger you will see:
The Overview link at the top of the page to display the following information:
  • Web server status for each logger computer (checks if the logger computer is connected to the Internet)
  • iMediaLogger running status (checks if iMediaLogger is running and updates every minute)
  • File purging settings
  • Disk space information as well as low disk space warning info
  • Links to newest files recorded for each feed and location
Operators can use this page to get a status of all loggers at once. This page automatically refreshes every few minutes. This might not always show the most recent up to date logger file please also go into BROWSER and preview them that way.

This is imperative... No logs means no license if the CRTC so chooses.

Logs and Fault Report


The Program logs are legal documents and MUST be signed at the end of each shift. Failure to do so is grounds for the CRTC revoking our broadcast licenses if they do a wrap and our logs dont match our logger audio.

The Music logs are used to reconcile the music that was scheduled with the music that actually aired. Any changes you make (additions, deletions, etc) MUST be documented on the Music Logs.

For AM, Producers MUST! Fill out SOCAN reports at the end of a shift.

Fault Reports

Fault any technical or equipment problems be sending a detailed email to the proper Fault Report Distribution Group in the Global Address List.

Fault any off airs, computer issues, etx as soon as they occur.

Faults regarding Programming commercials that Memo, loose EOM's on elements in MediaTouch, had to go to backup CDs during a Live To Air, etc should also be sent to the proper Fault Report Distribution Group.

It's a good idea to check the on call schedule as soon your shift starts, So that during your shift if there is an emergency to call some you know who to call.

Fault reports for AM530 should also contain things such as:
  • Producer did not show up or was late
  • Producer did not leave a backup CD so you played instrumentals
  • Logs are not where they are supposed to be, have gone missing or have been taken
  • A Producer would not abide by the "5 minute rule" and vacate the chair at the console to give you or the next Producer adequate time to set up.
  • Commercials were not played and why
  • Producers give you arguments about playing station commercials logged in their hours.
  • Too many people in the studio
  • Disrespectful or rude behavior, sexual harassment, etc
Fault reports sent to any email distribution group must also be written on the front page of the Program Logs. The Jewel does not leave Program Logs in the studios, but for Z103.5 and AM530, please write all faults on the front page and sign it. Reception sends out an email every morning recapping Fault reports and they base it off of the Program Logs. If your report is lengthy, print a copy of your email and attach it to the front of the log.
Fault anything that you think is out of the ordinary or that is an obvious problem.

Off Air" & "Dead Air

"Off Air" & "Dead Air"

First off the difference between "off air" and "dead air."

All three stations have air feeds. These are fed by receivers that are picking up the actual airwaves off the transmitter

If either station is off the air then all you will hear is static and noise. (In the case of Z103, you will likely hear 103.3 the edge in Buffalo). If we are off the air there is a problem with the transmitter.

Dead air means there is no audio getting from the studio to the transmitter Ė absolute silence. This can be due to a number of factors which are covered below.

(the following is assuming that operator error hasn't resulted in the afore mentioned pot being down or auto switch being off)

Diagnose the problem. Is the computer frozen? Is there audio on the board, but not on the air feed? Is there dead air or are we off the air? Check both the air feed and the program feed on the board!

You must become accustomed to using the back-up systems we have in place, you can follow these steps on your own.


FM Stations
  1. If there is dead air on the console, or the audio coming out of the main computer is compromised in any way, turn off the auto switch, kill the element and click PTA start on the next element.
  2. If the problem continues, or the computer is frozen, go immediately to a back up CD
  3. Then on the computer on your left hand side and double click on iMediaPix
    • Click the LOAD LOG button
    • Select todayís date from the list
    • Click the SYNC TO TIME button
    • Hit START
    • Turn on AUTO
  4. Now you have something back on the air and you can take a few minutes to reboot the OnAir (OpLog) machine. Once the reboot is complete, put the three pots down and play items in cue to make sure everything is fine. Once youíre satisfied, turn off AUTO on iMediaPix, wait for the element to end and fire the next element off the OnAir computer manually.
*** for The Jewel 88.5, a dead air scenario can be a little more complicated as the computer may be fine, but the Zephyr is down. Look at the Zephyr, located in the rack room. If there are not levels flashing on both sets of meter boards, and the main display does not say Connected on both lines the Zephyr needs to be redialed.

***Generally, the STL does not cause trouble for 103, but in some cases thick fog in the Caledon area has caused what is known as STL fading. When this occurs, it will resemble a dead air scenario. If there are levels on the board, and dead air is on the air feed, it is safe to assume the STL has lost its signal strength. In this event there is nothing an announcer or operator can do to get us back on the air.

If none of these steps work to put the station back on the air, Call ENG immediately!

AM Dead Air Procedures:

Anything longer then 10 seconds is considered dead air. Here are some steps that you should do quickly before you call engineering.
  • Is There Power going to the board? If not Call Engineering Immediately
  • If your oping switch to a song so you know there is audio being played (if your not opping get the producer to play a song and get in front of the board.
  • Make sure Control Room is set to AM PGM and the volume is turned up.
  • Make sure that the PGM button is on and the correct pot is up
  • Check your physical connections ( make sure the mic is plugged in, Aux cables are in the correct spot if your playing from a laptop)
  • If one of the mics is not working try switching the mics
  • If you are still having problems after you have tried all of these possible solutions call engineering.

    If the station is actually off the air (as described above) call ENG immediately. All of us have a remote control code that can reboot the transmitter over the phone. If the remote control fails, one of us will head to the transmitter site.

    Finally no one who is reading this e-mail needs to be reminded that being on the air is absolutely imperative for the survival of a radio station. With that in mind, I urge each and every one of you to take an active role in ensuring that some form of audio is being broadcast during computer problems or other technical glitches. Complacency and a the computer is broken, so its not my problemĒ attitude does no one any good.

    This era of automated broadcasting has led to many people in the industry feeling completely helpless when something goes wrong. We donít have huge CD libraries and back-ups of everything immediately available because there is a tried and true computer back-up system in place. And there is always a cd available

    Phone numbers for all engineers are posted in all control rooms, you do not have to go far to find us.
    FM Off Air Procedures

    The following is the procedures to follow in the event of any interruption to the audio coming from the On Air computers, the consoles, the Z103.5 STL, the Jewel Zephyrs or the transmitters themselves.

    The first step is to get audio back on the air.

    Back Up/Emergency CDs

    In the event that an On Air machine crashes, loses a network connection and can no longer access the audio server, there are backup CDs in both FM control rooms so you can get audio back on the air as quickly as possible before moving on to diagnose the computer problems.


    There is a binder in the back corner of the studio beside the music logs marked CIDC Back up. The binder has day part specific backup CDs. If the ON Air machine fails for any reason, grab a CD and get it on the air ASAP. Then try and get iMediaPix up and running. If you cant get iMediaPix running because the network has gone down, continue to play CDs and get on the phone to the After Hours On Call line and select the option for IT. If you cant find an IT person, call back and go through Engineering.

    88.5 The Jewel

    Backup CDs for The Jewel are located in the studio, on the desktop to the right of the On Air screen. They are day part specific and are clearly labeled for:
    • Morning Show: individual tracks, no IDs 2 hours
    • Middays/Weekends: 3 x 20 minute continuous sweeps with IDs
    • Afternoon Drive: Individual tracks
    • Crooners(The Lounge): sweeps 2 hours
    • Instrumentals sweeps: 2 hours
    • Overnights continuous sweeps : IDs
    • If you need to use backup CDs on either station, please make note of what times and what discs were played so that new ones can be burned and music can be reconciled properly.
    • Send a Fault report to the appropriate distribution group.

    AM530 Off Air Emergencies
    1. Make sure that it is in fact off air. Check the stream from the TX site Go to another location and check the AM air feed. Check in a car for example
    2. Make sure that it isnít anything self inflicted. I.e. producer turned off PGM feed. or are speaking into the wrong mic etc
    3. Contact ENG and let them know that the station is off air
    4. Send a fault report indicating that the station is off air.
    5. After the problem has been taken care off send a secondary fault with
      • how long we have been off air.
      • any commercials that were missed.
      • and what the situation was and how was it rectified.

    On Call Procedures

    Due to the increasing demands on the Operations department (IT, Engineering & Maintenance) we are taking steps to provide a better level of front line, emergency support by expanding our hours in the Toronto office and making it easier for you to contact us during after hours periods (evenings and weekends).
    The following information relates mostly to broadcast emergencies, but I would ask everyone to read it carefully. While we want to make phone support easier, we have enjoyed great success supporting the staff via e-mail -- still the most effective way to contact us when we are in the office which will now be 5am-6pm Eastern Monday to Friday. However, If a station is down (dead air or off air) Pick up the phone


    1. There is only one number you need to remember to get in touch with IT, Engineering or Maintenance 24/7
    2. 416-213-1035 the main switchboard number in Toronto.
    3. During office hours reception will forward your calls to the IT or Engineering/Maintenance department.
    4. After hours (6pm to 6am weekdays and all weekend long) you can press the number 3 when you hear the auto attendant (Youve reached the offices of the Evanov Radio Group) and follow the prompts to be connected to the person who is on call for either IT or Engineering/Maintenance.
    5. Locally (inside 5312 Dundas) you can dial 252 to reach IT and 250 to reach Engineering/Maintenance.
    6. AM operators can be reached at ext 174
    7. Please call from a Station Phone so that IT and Engineering do not see a random number.

    Support for the Morning Shows/Early Birds
    • We also staff the Morning Shows out of Toronto one of us will be in before 6am Eastern every weekday morning to deal with issues in Toronto as well as anything that arises in Ottawa, Hawkesbury or Halifax. In an emergency situation you can reach the person who is working the Morning Show shift by calling 416-213-1035 and entering that persons extension.
    • A complete calendar of who is on call, who is traveling and who is working the morning shift in Toronto is available at I ask each of you to surf to that site and take a look before picking up the phone.
    • E-MAIL IS STILL PREFERRED:During business hours and even during the Morning Show shift, if you have a minor IT issue please continue to e-mail IT or, for issues pertaining to studios and building maintenance email engineering.
    • ALL major issues require a phone call
    • HELP US HELP YOU:I would ask all of you to respect this new policy and do all you can, following the steps listed above, to contact the on call person, even if that means going to the website to determine who is on call and phoning them directly
    • IT is responsible for all computers, associated software & peripheral devices (printers, photo copiers), internet connections, e-mail and web streams at all locations as well as the main phone system.
    • ENGINEERING is responsible for all aspects of on-air including studios, transmitters and anything to do with audio as well as all phone lines and the phone systems in Ottawa, Hawkesbury, and Halifax and Brantford
    • MAINTENANCE Ė which shares staff with Engineering involves the upkeep of the buildings (plumbing, electrical, general maintenance).

    Control Room Etiquette/Duties/Rules
    • Under NO circumstances is anyone to leave leftover food/wrappers/garbage in any of the control rooms. Take your garbage with you. If it is brought to the attention of Operations/Engineering or Management that this is happening, we will have no choice but to BAN all food from the studios.
    • Under NO circumstances is liquid of any kind to be within 5 feet of an on air console or any other electronic equipment. Drinks must be in re-sealable containers and must be kept well away from the equipment. Spills into equipment of any kind MUST be reported to the Engineering Department AS SOON AS IT HAPPENS! Time is of critical importance when it comes to spills and can mean the difference between a station being on or off the air. Paul Evanov has stated that any liquids found within 5 feet of ant critical equipment is grounds for immediate dismissal and that pertains to all on air staff as well as Operators.

    Nightly Operator Duties

    Operator Duties

    1. Make a check of all 3 stations air feeds a minimum of 3 times an hour. Check all loggers once per hour. Send station check emails to Engineering
    2. Make a check of all three studios a MINIMUM of once an hour. If your on AM this means the lower studios and if your on FM this means the upper studios The physical checks include checking that all the doors are closed and lights are off. All Studios are neat and Tidy and no Equipment is missing.
    3. Making sure that both 88.5 Zephyrs are connected. If one has dropped, redial it. If it wonít redial, but the station is on the air ( double check with the AM Op), send a fault report to the proper Fault distribution group. If one or both units have dropped and will not redial and the station is off the air, immediately call the After Hours On Call line and select the option for Engineering.
    4. Checking the 88.5 On Air machine to ensure it is running on time, or as close to it as possible, and that no weekend infomercials are going to memo and cause the station to run ahead of time
    5. Check the paper music logs for Z103.5 against the On Air computer and make sure everything matches up. If the odd element is out of place, move it where it should be and send a fault report. If a larger number of elements are out of place, or the whole log doesnít match, call the After Hours On Call number and select the option for I.T. Someone from I.T will lead you through re loading the log or if necessary,. They will log in remotely and re merge the log for you. If you cant reach someone from I.T in a timely manner call back through After Hours and select the option for engineering. Paper log is always right.
    6. Make sure there are IDís between each song between 12am and 5:30am on Z103.5 Time out to start of the morning show properly.
    7. Keep the studios clean and organized. Make sure all Traffic/Promo tags are put away in the appropriate binders. A general cleanup of the studios should be done each night. Garbage, empty coffee cups, papers etc should be cleared out of the studio each night. If the garbage is overflowing, please take it out back and throw it in the bin. The cleaners usually leave an empty bag folded up in the bottom of each garbage can in case that happens. Clean the equipment according to the schedules posted in each control room and initial them. If we are running low on cleaning supplies, email Angie
    8. As required Get TV audio clips for the Morning Show. (more detail on this in another section)
    9. Fault all technical, Programming, etc issues to the proper Fault Report Distribution email group and also write it on the Program Log. Write the page number on the front of the Program Log and write the fault report on the time that it occurred.
    10. Make a final check of the On-Air machines and the logger before you leave when your shift is over

    Live to AIR Operating Procedures - In Studio
    1. Be in or near the Z studio NO LATER than 9:15pm as there are some nights when announcers VT a portion of the 9pm hour in order to make it to the club on time.
    2. If the announcer is still in the chair at 9:50pm, politely ask them to let you set up quickly for the LTA
    3. Have the Z_ZEPHYR (or AM_ZEP_2 if there is an issue with the Z Zephyr) source in CUE on the board.
    4. If you have not heard from the club op by 9:30pm, call them on their cell phone immediately and ask for an update.
    5. Use the TalkBack (TB) button on the STUDIO 2 control panel to communicate with the club op. Give the club op their break times for all three hours and discuss whether or not a song needs to be added or deleted to time out to 10pm.
    6. Send the club op the break times over the talk back or through text message.
    7. Should you need to add music due to an issue at the club end (technical problem, DJ was late, host asked for an extra song, etc), add NO MORE THAN ONE CANCON SONG. If the club is still not ready, start the backup LTA CD for that night. Send a fault report as to why the LTA started late or the back up located on media touch production.
    8. Check your commercial breaks against the Program Log and make sure there are Back To IDs at the end of each break.
    9. During commercial breaks, keep the club op updated on how much time is left in the break (2 minutes, 1 minute, 30 seconds, 10 seconds to the ID).
    10. When returning from a break, do not put the Zephyr pot back up until the very end of the back to ID.Pot back up on the 3-5 of Z1035.
    11. As soon as the LTA intro rolls, or the back to ID rolls at the top of each hour, make sure you have started the backup CD or backup segment from iMediaProduction at the same time so you already have a backup audio source rolling if the feed from the club drops
    12. If the signal from the club drops, wait NO MORE THAN 5 seconds before going to the backup. Then get in touch with the club op on cell phone to let him/her know the lines have dropped.
    13. When returning from a backup segment to the live club feed, roll a dry LTA ID as you fade down the backup and pot up the Zephyr feed. Youre using that ID to cover up what youre doing and it should sound seamless to the average listener.

    Live to AIR Operating Procedures - Club OP
    1. Be at the station to double check your kits and pick up your gear NO LATER THAN 9:00pm, earlier depending on the location of the club. Give yourself time to deal with any unknowns like weather and accidents that may delay you getting to the club on time.
    2. As soon as you arrive at the club, IMMEDIATELY get the Zephyr plugged in and dialed back to the station. This gives you time to troubleshoot any issue that may arise
    3. Bring BOTH Zephyr kits into the club. DO NOT leave one in the car. The Zephyr and all its assorted parts costs in the ballpark of 10 thousand dollars. Donít risk the car being stolen and the gear disappearing because you left it in the car.
    4. Stay in contact with the studio op via TB, phone or text as necessary.
    5. Monitor the CAN CON percentage closely, especially with newer DJs. The hosts are all educated in how much CAN CON we have to play and the percentages are written on the LTA Music sheets. If a DJ gives you grief about playing CAN CON, send a fault report and Hammer, Danny and Paul will deal with the DJ correctly.
    6. Pay attention to the Zephyr. Make sure it stays connected at all times and if it drops, get it re-dialed ASAP.
    7. Submit fault reports on your own behalf as to any issues that happened at the club. Dont rely on the studio op to do it for you.
    8. Fault any and all problems with any of the LTA gear broken cables, missing cables, drinks spilled on a Zephyr, etc so they can be looked at and repaired/replaced ASAP.

    Restarting On Air and MProd Machines

    On Wednesday and Saturday nights during the overnight, all 4 FM studio computers MUST be restarted. Here is the proper procedure.
    1. Check both machines to see if there are Windows Updates waiting. If there are, start downloading them just before you want to restart the machine. Install the Critical Updates only. When they are finished installing, if you get the message that Windows must be restarted, click on No until you are ready to actually restart the machine. If you time it properly the updates will be installed and you wont have to wait for them before you restart and you wont have to click on No too many times when the annoying Restart dialog box keeps popping up every few minutes.
    2. Restart the MProd machine first.
    3. When the MProd is finished rebooting, double click on the iMediaPix icon. Or the Media touch On air icon on the MProd.
    4. Click the LOAD LOG button, select todayís date and open the file.
    5. Turn AUTO OFF on the On Air machine and find a cross over point. Delete items in iMediaPix if necessary to make the log match where you are on the On Air machine.
    6. Make sure the Mprod pot on the console is in PGM, is ON and the pot is up. Start the first element in iMediaPix and turn AUTO ON.
    7. Bring the PTA pots on the console down.
    8. On the On Air machine, click/touch the ON AIR button in the top right hand corner.
    9. Click/touch QUIT ON AIR and answer YES.
    10. 10. Restart the On Air machine.
    11. 11. When the machine reboots, it will automatically launch the On Air software, load the log and sync to time. At this point, turn AUTO OFF, click on the ON AIR button, click on QUIT ON AIR and answer YES again. The ON AIR program will shut down again. Wait about 30 seconds and launch the program again manually. Turn AUTO OFF and wait another 30 seconds. Then, test the Next Event button by firing off a few elements. If the Next Event button works, delete any remaining items from the log that have already been played to sync up to the proper time, turn the PTA pots back on and put the faders up.
    12. 12. Pick a cross point to go from iMedia Pix back to On Air. Turn AUTO OFF on iMediaPix, fire off the first PTA element from On Air, put AUTO back ON on the On Air machine and carry on.
    When all the machines have been successfully restarted, send an email engineering indicating that all machines have been restarted.

    Canadian Content Rules/Adding and Deleting Songs

    Z103.5 and 88.5 The Jewel MUST play AT LEAST 35% Canadian Content music (referred to as CAN-CON) to meet their license requirements. Failure to live up to this percentage could cost us a license. The percentage scheduling is taken care of by the Music Department for each station.

    CAN-CON tracks must NEVER be deleted between 6am and midnight, 7 days a week or we run the risk of falling short of the 35% commitment. This can land us in deep trouble with the CRTC and SOCAN if we are ever audited or wrapped.

    If you find yourself in a situation where you need to add or delete songs from either stations On Air machine to time out an hour between 6am and midnight, here are the few simple rules to always remember about CAN-CON:
    1. If you are working between 6am and midnight and you need to ADD music to time out an hour (LTA host requests you add a song, DJ shows up late etc), ADD ONLY CAN-CON tracks. CAN-CON tracks are found in the ZMA category for Z103.5. For 88.5 The Jewel, there is a binder in the studio called Jewel Canadian Content with their CAN-CON library divided into Vocal, Instrumental and Crooners categories.
    2. If you have to DELETE tracks to time out an hour that has been overscheduled for some reason, DELETE ONLY INTERNATIONAL tracks.
    3. If you are working between midnight and 6am you can delete EITHER CAN-CON or International tracks, but if you have to ADD music during the overnight, please add ONLY International tracks. See Paul Evanov guidelines further along regarding adding International tracks overnight.
    In the EXTREMELY rare case that you are left with nothing but CAN-CON in the 9pm hour and that means the 10pm LTA is going to start too late, you MUST play AT LEAST 90 SECONDS of each song remaining in order for us to get the CAN-CON credits.

    Changes have been made to the music clock for that hour so that issue should not arise often, if at all anymore.

    Points To Keep In Mind When Adding Music (from Paul Evanov)
    1. If you are short music by 3 minutes or less, you do not need to add a song. If you are short music by over 3 minutes you may add a song to assist in timing out to the top of an hour. You do not need to be exact in timing out.
    2. Please use the music library to its fullest potential and use a variety of song choices when adding music. It does not need to be the same songs every time you operate.
    3. When adding songs please look to see when the song was last played and look ahead to see when it is scheduled to play again.
    4. Please separate plays from the same artist by at least two hours.
    5. Please separate plays of the same song by at least three hours.
    6. When adding music, it is not an opportunity for you to play your favourite songs or personal requests. Please do your best to add music that reflects the sound of Z103.5
    7. If you have the opportunity to fill a listener request when you add a song please take advantage of that opportunity, keeping the above guidelines in mind.
    8. Never drop a CANCON song.

    Security/Energy Conservation/Power Outage


    When you leave the building, please make sure that the door you exit closes fully behind you. Operators should be checking the front, side and basement doors as part of your building checks.

    Energy Conservation

    Lights are being left on all over the buildings after hours. This is an unacceptable waste of energy. If you are the last person out of your work area at night or on the weekends, please make sure all lights that donít need to be on are turned off. Please make sure all basement board room, washroom and kitchen lights are turned off when not in use. The Only lights that are to be left on have a red dot on the switch.

    Power Outage

    There are UPS units (battery Backups) are on all the ON AIR critical machines at 5312 Dundas. There is also a standby generator which should start immediately. In the event of a power outage and this does not occur call ENG IMMEDIATELY

    How to setup a zephyr at the club

    How to setup a zephyr at the club:

    1. Plug in phone line to the black jack

    2. Run RCAs from Record Out/AUX out of DJ Mixer to inputs 3&4 on Zephyr. Use quarter inch bullets in order to insert RCA cord into zephyr. Plug mic cord (XLR) into input 1. Plug your headphones into either headphone jack 2 or 4 depending on where you and announcer are standing (for easier access on front panel) Turn ON.

    3. Time to load the location setup for where you are. Hit AUTO -> and then type in "1 0 0".You'll now get a list of places. Scroll to yours and hit SEL. Follow prompts and then reboot when asked.

    4. Once rebooted, hit TEL button to see status of line. When both say READY READY, you are good to dial. Hit AUTO and scroll to the zephyr you are connecting too. You will either be connecting to Z ZEPH 1 or Z ZEPH 2 unless otherwise instructed. Once highlighted, hit SEL, then hit TEL to see the status. When connected, you'll hear the box beep, and you should begin to hear levels out your headphones, and see levels on the VU meters at the front.
    5. Controlling what goes in to the Zephyr is all done via the front panel. The top row controls your inputs, while the bottom row controls the output to headphones. Each input has 4 different settings, as indicated by the two green lights above and below each button. They are as follows:
      • A) Audio to left channel (top light on)
      • B) Audio to right channel (bottom light on)
      • C) Audio to both channels (both lights on)
      • D) Off (lights off)
      For input 1, you always want it to be feeding audio to both channels (D) since that is the MIC input. For inputs 3 and 4, you want them each to feed a separate channel (stereo -> left and right). Typically 3 is A and 4 is B.

    6. This button to the right of the headphone level knobs controls what you hear in your headphones. It operates in a similar way to the inputs above.

      Again, there are 2 lights which help you see what status it is in
      • A)SND mode. You are hearing everything you are sending (top light). You can view your levels on the VU meters marked "SEND"
      • B)RCV mode. You are now hearing what the station is sending back (Z air feed) (bottom light). You are typically only in this mode when not live/in commercial break.
      • C)SND/RCV mode. Never used. Both the SND and RCV are sent to your headphones. Both lights lit.
      • D)OFF
    7. Optimal levels

      Zephyrs are very finicky. You do not want to clip the signal being sent back to the station, as the zephyr tends to introduce artifacts like static when this happens. When the announcer is just talking and only music is playing, levels should be in between -20 and -10 on the SND meter. When the announcers is talking over the music, the levels should only be a tick or two over -10. One bar of red on the VU meters is okay. Any more is bad news. The RCV meter is controlled by the STUDIO 1 knob on the board in Z Master Control. It's best set around -10 so that when you switch between SND and RCV in your headphones, you aren't blown away by a huge volume discrepancy. Have the studio op move the knob slowly up and down to the desired level.
