Power Supply
The AIR 3 console is powered by a factorysupplied power adapter with 100-240V/50-60Hzinput, 50W maximum output power, and a 4 footlong output cable.
DC Power Output Pinout
The power supply adapter is supplied with a 3-wire grounded AC cord that
should be plugged into a clean AC power source, that is, an AC source that feedsonly the control room audio gear. This source should be a separate feed from thosepowering lighting, air-conditioning, or any other non-audio machinery.
Energizing
Assuming the AIR 3 console mainframe is properly placed, and its power supplycorrectly connected to the console, you may now energize the power supply adapterby plugging it into the AC mains. The consoles individual module switches willassume factory default settings.
Note: To de-energize the console, unplug the power supply adapters AC cordfrom the AC mains.Never de-energize the console by disconnecting the cable thatconnects the console and power supply adapter together.

Audio and Control Wiring
All audio I/O connections to the AIR 3 console are made via RJ-45 connectorsand 6-pin plug terminals located on the rear panel of the console. For controlconnections there is also a multipin DB-25 connector. See the consoles reardrawing on page 1-8.
Unbalanced Connections (analog audio)
ANALOG INPUTS Wire to the console with typical shielded two conductorcable (like Belden 9451), just as if you were connecting a balanced source. At theunbalanced source machines output, connect the black wire (LO) to the shield.
ANALOG OUTPUTS AIR 3 consoles use a balanced output circuit whichbehaves exactly like the secondary of a high-quality transformer, with no centertapthis output is both balanced and floating. Either the HI or LO side of the outputshould be strapped to ground, with the output taken from the other side. (Normallyyoud strap LO to ground, and take HIGH to feed your unbalanced equipment.)
The power feed recmended in the texoften installed and
ferred to in studiosan isolated AC grououtlet. It is usuallyange in color.

Hook-Ups
The rear of the console has multiple RJ-45 connectors to plug in 24 stereo line inputs,the external input, caller connections to and from hybrid, as well as providing studio,control room, microphone, PGM, and USB analog output connections. There is also a6-pin plug terminal (CT7, on the CONA3-4 PCB) provided for microphone inputs.
A DB-25 is provided for control connections and for the Cue output.
There is also a USB port with type B connector available for interfacing with acomputer (see page 2-4 for details).
Pinouts drawings on pages 1-9 through 1-11 show all wiring connection at glance.

To START Remote Source Machines Using Channel START Switches
EXTERNAL START Hook up the remote machines start control pins to theDB-25 connector control pins; for example, for channel 1 wire to Start Channel 1, Pin 1,
and Start Common, either one of the Pins 13 - 18.
MIC 2 Talkback to Cue/Control Room
The talkback to cue logic input is used to connect an external user-supplied button thatenables the person activating it to talk to the operator in the control room, via theconsoles cue speaker. Provide a closure between Mic 2 TB to Cue/CR, Pin 11 and Mic 2TB to Cue/CR Common, Pin 12. This will cause the channels pre fader signal to be sentto the consoles Cue bus, where it may be heard by the console operator. This non-latching condition continues until the closure is released. (Requires a user-suppliedmomentary action TALKBACK switch at the studio microphone location.)
On Air Tally
Lets any programmed channels START switch control an on-air light or othermicrophone on indicator at a remote location. This control function provides a contactclosure between Pin 9 (On Air Tally N.O.) and Pin 10 (On Air Tally Common) wheneverthe module is ON.
This signal can be used to control an externally powered tally light that requires acontinuous closure to function. Current should not exceed 2 amps at 30 volts DC.

Console Features
Overview
Each AIR 3 console has two Input panels and one Master panel. The Input panelconsists of six faders with associated switches. The Master panel has a PHONE section,a CONTROL section, a HEADPHONE section, and a STUDIO section. Each section isdescribed below.
The basic purpose of the console is to take some of the many audio signals that are
wired to the console inputs, and generate several outputs that combine these inputs invarious groups and at various degrees of loudness, or signal strength. The typicalapplication is in a radio station where it is desired to develop the signals that the stationwill broadcast (the on air signal), as well as several additional signals for recording andmonitoring.

Inputs
The AIR 3 console is designed to handle up to 24 analog stereo pro level (+4dBubalanced) inputs, two mono microphone (-50dBu nominal) inputs, and one externalstereo line level (+4dBu balanced) input that goes directly to control room or studio.
The AIR 3 also has one analog (+4dBu balanced) input dedicated to use asa telephone caller input.
Analog Mono Mic Level Inputs
These inputs are used to connect to microphones, which typically put out signals atrelatively low signal strength, and therefore require more amplification (increase insignal strength) to be properly audible in the output. Mic level sources are wired to a 6-position plug terminal located on the rear of the console. On the rear of the console alsoare a pair of RJ-45 connectors used for MIC outputs, and the MIC 1 and MIC 2 GAINtrimpots for adjusting the level of each microphone input independently.
Example: with a microphone input of 60dBm @150ohm at the port, gain trim can set levelsfrom -22dBu to +16dBu (note maximum preamp gain is +76dB) at the PGM 1 or PGM 2 output.
These microphone connections are to the inputs of two internal microphone pream-plifiers. In order to actually hear the microphone audio, the microphone preamplifieroutputs must be wired to the desired line inputs that feed the faders you will use to control
the microphone levels.Looking at the rear of the console, there are two RJ-45 connectors towards the left
end of the console labeled MIC 1 OUT and MIC 2 OUT. These are the outputs,respectively, of the MIC 1 preamp and MIC 2 preamp.
In a typical installation you will want to feed the mic signal to both left and right sidesof the stereo line input. For this reason, we have duplicated the MIC OUT signal as bothleft and right, so that a simple RJ-45 patch cord will carry the mic signal to both left andright sides of the stereo input of whichever line input you want the mic to feed.
Analog Stereo Line Level Inputs
These inputs are typically used to connect to machines, such as tape decks, cart
machines, CD players, etc., that provide analog outputs. As mentioned above, you canalso feed these inputs from the outputs of the internal mic preamps.
Outputs
The console main analog outputs include two Program stereo buses (PGM 1 andPGM 2). The Program stereo outputs can be programmed to mono outputs via dipswitchSW 1 (described in the Console Internal Programming section).
Monitor outputs include a stereo Control Room output, a stereo Studio output, amono cue output, and a stereo headphone jack.

The consoles mono cue signal feeds the internal speaker in the meterbridge, andalso provides the cue signal used to interrupt Control Room and headphones, if suchinterrupt has been enabled by the installer.
USB PortThe console contains a USB 2.0 interface, avail-
able via the USB Type B connector on the rear panel,to enable audio to pass between the console and aUSB port on a computer. Internally, dipswitchesselect either PGM 1 or PGM 2 as the audio from theconsole to the computer (see Console Internal Pro-gramming). Audio coming back from the computervia USB shows up as a stereo analog signal on theUSB ANALOG OUT RJ-45 connector. From there,the audio can be patched to any line input, or to the external input.
Using the USB Port . . .
Any computer having a USB port and installed drivers capable of passing andutilizing digital audio data should work with the Air 3 USB port. Use a cable having aUSB Type B connector on the Air 3 end and a connector on the other end that will matewith the computers USB port; this will typically be a USB Type A connector.
. . . With a MAC
In general, this will be a plug-and-play process. The main concern is to choose theUSB Audio Codec under System Preferences>Soundas desired for audio input and/or
output. Then simply start the application.
. . . With a WindowsPC
When you first connect the Air 3 USB port to a PC running Windows you will seethe famous found new hardware sequence of messages. At some point this sequenceshould end with a message that the new hardware is installed and ready to use.
Setting up any given application to use the Air 3 USB port will depend on theapplication itself. Generally, you will need to select the appropriate device from a listof devices in a Preferences dialog.
As an example, lets look at WinAmp, a free software application used by millionsto play back audio streams from a network (or the Internet), or to play audio streams into
a network.To play audio from the Air 3 on the computer:
Install the free LineIn plugin for WinAmp.
Under Preferences - Inputselect the LineIn plugin from the Input list and clickConfigure, then find the USB Audio Codec in the list of available devices and noteits corresponding device number, which you will need below.
In WinAmp, choose Play URL...
Enter line://dev=n where n is the device value that you discovered above.

C O N S O L E F E A T U R E S
Now when you click Play, WinAmp will play the Air 3 audio on the output deviceselected in WinAmp. This could be speakers, a sound card, or even an outputstream.
To play audio from the computer on the Air 3:
Under WinAmp Preferences - Outputselect an output plugin and click Configure,then select the USB Audio Codec as the device.
Play the desired computer audio with WinAmp and the audio will appear at theUSB ANALOG OUT connector on the back of the Air 3. You must patch thisoutput to the desired fader (using the appropriate connector from the INPUTSbank), or to the EXT IN if desired, to route the audio.
Other Computers
If your computer does not use one of the above operating systems, or otherwisebehaves differently than described above, consult the documentation for that computer,
operating system, and/or application.
General Considerations
If any problems are encountered, please consider the following points:
The audio that is output from the Air 3 on the USB port depends on the setting ofthe internal dipswitches that select between PGM 1 and PGM 2 as the source (seeConsole Internal Programming).
The audio coming back into the Air 3 on the USB port is available at the USBANALOG OUT, which mustbe patched to a line input if you want it to come upon a fader, or to the EXT IN if you want it available only in the monitors, or to someexternal device if thats where you want it to show up.
If you are not able to get the audio into or out of the USB port, check the USB cable,its connections at both ends, and the port selection settings in the application youare using.
If you have the audio flowing where you want and it suddenly becomes intermittentor disappears, check the USB cable and the connections at both ends.
Once you have the USB audio under control it is a good idea to make a record ofthe application being used, including its version number, the audio direction (intoor out of the computer), and all the settings that were required to make it work. Thisinformation will be invaluable if you later have to troubleshoot the USB audio, orset it up on another computer.
Mute and TallyThe console has the ability to mute the control room output. The console also has an
ON AIR tally output that is used to drive user-provided external circuitry that will in turnoperate the control room on air indicator. This tally is automatically activated wheneverthe control room mute is activated. Thus, turning on any module that activates thecontrol room mute also turns on the ON AIR tally. Whenever this tally is activated theON AIR indicator in the meterbridge will also illuminate.
See the Console Programming Options section for details.

Console Programming Options
All programming (except for the headphone split cue option and selection of audioto feed to an external computer via the USB port) is made via three PCB mounted
dipswitches located on the consoles rear panel. One dipswitch (PGM/CUE switch) ison the top left side of the rear, and programs the control room cue, the studio dimfunction, and the mono program outputs. The two other dipswitches (CR MUTE/AIRTALLY) are in between the two groups of INPUTS RJ-45 connectors, and activate CRmute and AIR TALLY.
PGM/CUE Dipswitch
When a PGM/CUE dipswitch position is up it is ON.
Cue Interrupt
The dipswitch pos. 1, when activated, sends cue to the control room.
Split Cue, Control Room
The dipswitch pos. 2, when activated, allows a summed (L+R) version of the regularprogram to be sent to the right side of the CR monitor stereo output, while CUE is sentto the left side.
Split Cue, Headphone
Consoles are normally programmed at the factory for CUE to appear on the leftchannel, while L+R sum of the control room output appears on the right. This can bechanged with jumper J1 on the back side of the Master Panel. The jumper normally spanspins 2 and 3 of the jumper header. To defeat this split cue option, move the jumper to span
pins 1 and 2 instead. Then cue will interrupt both sides of the headphones.
Studio Dim
The dipswitch pos. 3, when activated, allows normal studio audio to DIM (drop-20dB in level) when talkback to studio is engaged. If this dipswitch is not activated, thenormal studio audio is completely interrupted by the MIC 1 audio when talkback tostudio is engaged.
If the studio is programmed to DIM talkback audio could presumably make it fromthe studio monitor speakers to the open studio mic.

Program Mono
The dipswitch pos. 4 - 7, when activated, sums the left and rightPROGRAM channels and sends L+R to the appropriate channel:
Pos. 4 - sends L+R of the PGM 1 to the PGM 1 LT channel;Pos. 5 - sends L+R of the PGM 1 to the PGM 1 RT channel;
Pos. 6 - sends L+R of the PGM 2 to the PGM 2 LT channel;
Pos. 7 - sends L+R of the PGM 2 to the PGM 2 RT channel.
USB Source Dipswitches (internal)
Dipswitch 2 on the CONA3-4 board is used to determinewhether PGM 1 or PGM 2 will feed the USB link. Positions 1and 3 should be on to feed USB with PGM 1, while positions 2
and 4 should be on to feed USB with PGM 2. If PGM 1 is to beused, the PGM 2 positions should be off, and if PGM 2 is to beused, the PGM 1 positions should be off. DO NOTactivate bothPGM 1 and PGM 2 simultaneously!
CR MUTE/AIR TALLY Dipswitches
When a CR MUTE/AIR TALLY dipswitch position is down it is ON.
CR Mutes
An input channel can be programmed to mute the control room speakers when thechannel is ON. Positions 1 through 12 and caller (13) of the dipswitches, when activated,automatically mute the consoles control room speakers when the corresponding channels1 through 13 are turned ON. This is done to prevent feedback from the CR announcersmic. At the same time the ON AIR LED in the center of the meterbridge will light up.

Source Select
Each input channel accepts two analog stereo sources: A and B,switched at the top of the panel. The A/B button will be lit when source B
is selected.
Program Assign
Output switches assign the selected source signal to any combinationof the consoles two stereo Program outputsPGM 1 and PGM 2. Thebutton will be lit when the source is assigned to its respective bus. Toremove a source from the bus, press the button again; the light will go offto indicate that the source is no longer assigned to that bus. NOTE thatwhen the console is powered up all input channels will be off, with sourceA selected, and assigned to PGM 1.
Recessed rear panel trimpots adjust the left and right levels of PGM 1
and PGM 2 outputs.
Cue Button
A CUE switch places the channels signal on the consoles cue bus,where it may be heard on the meterbridge mounted cue speaker, as aninterrupt to the console operators headphones, and as an interrupt to thecontrol room monitor speakers, if so programmed.
Press the CUE button. The channels input signal will be included inthe consoles CUE output at a level that is independent of the FADERsetting, and the button will light. The fader does not need to be turned ON.To remove a fader from cue, press the CUE BUTTON again; the light will
go off to indicate the channel is no longer assigned to cue.
Fader
Level is set by a long-throw fader. The fader is the sliding mechanismthat determines how strong is the presence of the input in some of thevarious console outputs.
If the fader is all the way down (that is, pulled toward the consoleoperator), the signal will not be present in either of the two program mainbuses to which it is assigned. As the fader is moved up (that is, pushed awayfrom the console operator) the signal will appear more strongly in each ofthe main buses to which it is assigned.
ON Button
The ON button turns the channel on and off by means of electronicswitching and can simultaneously start external source machines. Thechannel is ON when the ON button is lit. These can also be programmed(as mentioned in the previous chapter) to activate control room mute andon air tally.

Caller Input
The caller section is used for the telephone call-in talk segments, andcontrols the audio for the caller. The caller signal enters the console fromyour station hybrid.
The caller feed can be either or both of the two Program buses. The callerfeed will never contain the callers own voice.
A recessed rear panel trimpot adjusts the caller output level.
Program Assign
Output switches assign the caller to any combination of the consoles twoProgram outputs (PGM 1 and PGM 2), and permit live talk-ins.
Pressing either of the two program switches causes the callers audio tobe included in the output mix for that bus, at a level dependent on the FADERsetting, as long as the caller section is ON. The button will be lit when the
caller is assigned to its respective bus. To remove the caller from a bus towhich it is currently assigned, press the button again; the light will go off toindicate that the caller is no longer assigned to that bus.
CUE Button
The CUE button allows interviewing the caller prior to airing by includ-ing the callers voice in the consoles cue bus, where it may be heard on themeterbridge mounted cue speaker.
TB Button
When the TB switch is pressed (it is momentary action), the microphone
(MIC 1) will interrupt the regular caller signal, thus allowing the DJ to talkto the caller prior to airing.
Fader
The long-throw fader sets the callers signal level.
If a fader is all the way down the callers voice will not be present in eitherof the two Program buses (PGM 1 and PGM 2) to which the phone isassigned. As the fader is moved up the signal will appear more strongly ineach of the main buses to which the phone is assigned.
The fader position will also affect the strength of the caller in the cueoutput.
ON Button
The ON button determines if the phone channel is ON or OFF. Thechannel is ON when the ON button is lit. The button can also be used toprovide external start logic for the hybrid.
If the phone channel is OFF, caller signal will not be present in any mainbus output, regardless of the status of the PROGRAM ASSIGN buttons orthe position of the fader. If the phone channel is OFF its signal will still bepresent in the cue output if it has been assigned to cue.

Caller Set-Ups
Pre-air segment communication between the console operator (DJ) andcallers is aided by the CUE button, which places the callers voice on theconsoles cue speaker and headphones, and (if so programmed) CR speak-
ers. Additionally, pressing the caller TB switch sends the MIC 1 signal tothe caller output.
A typical call-in segment might proceed as follows:
Caller phones in, DJ picks up off-air during a track play to set up the call.He places the caller in CUE, and talks to the caller by pressing the TB button.Neither the DJ mic nor the phone channel need to be ON for two-waycommunication.
When he is ready to take the call on-air, the DJ makes sure his mic andphone are assigned to PGM 1 or PGM 2 and turns them ON. He thendeactivates caller CUE to hear the normal feed.

Control Room Monitor
This is the console operators monitorthat allows the operator to listen to theconsoles two stereo Program outputs andan external stereo line level input. Thissection of the console includes the moni-tor level controls for the control room,headphone, and cue circuits.
In a typical radio application the con-sole is located in the Control Room. Speak-ers in the Control Room allow the consoleoperator to listen to the console bus out-puts to be assured that the console isperforming as desired. These speakersare fed by a stereo signal from the
consoles Control Room output. In addi-tion to the Control Room output, theoperator may also desire to listen to spe-cific isolated faders via the cue systemand the consoles internal cue speaker, ormay want to listen via headphones. Thus,the control room monitor consists of theabove mentioned level controls, alongwith two program assign (PGM 1 andPGM 2) buttons, and an external input(EXT) button.
In some instances the console operator may also be performing talent whose voicewill be heard over the radio. The operators microphone may thus provide a part of thesignal that is going out over the air. If that signal is the one being monitored with theControl Room speakers, there is the potential for feedback. The amplified signal fromthe Control Room speakers is picked up by the microphone and amplified to a new,higher, level, which then is once again picked up by the microphone. The signalquickly rises to an ear-splitting screech. To prevent this, the operators microphoneis normally set to MUTE the Control Room output to prevent the occurrence offeedback.
The master CUE circuit drives a meterbridge-mounted speaker through a built-inpower amp, and can be programmed to interrupt control room feed, or provide a splitfeed (program mono sum to right, cue to left) to the control monitor speakers. It also
automatically interrupts the headphone feed.
Program Select
Pressing either of the two program (PGM 1 or PGM 2) switches allows the operatorto listen to the selected output bus. The button will be lit when the monitor is assignedto its respective bus.

EXT Switch
Pressing the EXT switch allows theoperator to pick up the external input (use-
ful for such items as tape recorders or airreturns) to listen.
CONTROL ROOM Level Control
The CONTROL ROOM level controldetermines the overall loudness of thesignal being monitored as it appears in theControl Room speakers. As the control isturned clockwise, the loudness increasesup to a maximum at the limit of mechani-cal rotation. To decrease the loudness,turn the control in a counterclockwise
direction.
NOTE: If the Control Room is mutedand you turn the level control all theway up, then remove the condition thathas the Control Room muted, the soundin the Control Room speakers willsuddenly be VERY LOUD!
CUE Level Control
The CUE level control determines the overall loudness of the cue signal as itappears in the consoles cue speaker (located behind the grill in the
METERBRIDGE).
Like the Control Room speakers, the cue speaker also has the potential forfeedback. To avoid this situation, operator mics that mute the Control Room willalso mute the cue speaker.
NOTE: If cue is muted and you turn the level control all the way up, then removethe condition that has the cue muted, the sound in the cue speaker will suddenlybe VERY LOUD!
HEADPHONE Level Control
The HEADPHONE level control determines the overall loudness of theheadphone output signal, which monitors the same source (PGM 1, PGM 2, orEXT) as the Control Room speakers.
The headphone output signal appears at the HEADPHONE JACK, locatedbeneath the armrest near the right side of the console. The jack is provided as a placeto plug in user-supplied stereoheadphones having an impedance of 60 Ohms orhigher.

Studio Monitor
In addition to the Control Room, theremay be a Studio in which one or moreperformers will be assembled, usuallywith microphones so that their voices canbecome part of the mix. Speakers may beprovided in the Studio to allow the talentto listen to the console bus outputs attimes that they are not actually on air.These speakers are fed from the consolesstereo Studio output.
The studio monitor consists of a STU-DIO level control, a TB (talkback) but-ton, two program assign (PGM 1 andPGM 2) buttons, and an external input
(EXT) button.A connection is provided on the
consoles DB-25 connector to wire up aMIC 2 TB to CUE/CR switch providedby the user. This switch enables a guestusing MIC 2 to talk back to the ControlRoom over the consoles cue system.
Program Select
Pressing either of the two program PGM 1 or PGM 2 switches allows theselected output bus to be heard in the studio. The button will be lit when the monitor
is assigned to its respective bus.
EXT Switch
Pressing the EXT switch allows the external balanced input (such as taperecorders or air returns) to be heard in the studio.
STUDIO Level Control
The STUDIO level control determines the overall loudness of the signal beingmonitored as it appears in the Studio speakers.
TB (Talkback) Button
The TB button lets the operators microphone signal interrupt the normal feedto the studio speakers, allowing the operator to talk to the performers in the Studio.If the Studio Dim dipswitch (described in Chapter 2) is set to the ON position, thenormal studio feed is not completely removed, but is dimmed by 20dB.

Meters (VU-AIR3)
The METERS section consists of two VU meter pairs on the consolesmeterbridge and a METERS select button, located on the Master panel.
VU Meter Pairs
VU meter pairs (PROGRAM 1 VU and SWITCHED VU) are stereoLED bargraph type meters.
The level of the signal being metered is indicated by the number of
display elements that are lighted. The more elements lighted, thestronger is the signal being displayed. The right four LEDs in eachbargraph are red to indicate when the signal level is approaching aclipping (distorted) level. The next four LEDs are yellow, indicating anormal level range, and the remaining LEDs are green. The top member of the pairindicates the level of the signals left channel, while the bottom member of the pairindicates the level of the signals right channel. Peak (CLIP) indication is alsoprovided.
The left VU meter pair shows the level of the PGM 1 output, while the right VUmeter pair (the SWITCHED VU) shows the level of the signal that is selected forit (PGM 2 or EXT).
METERS Select Button
The METERS buttons select the source for the switched meter pair, as indicatedabove.
On Air LED
The ON AIR LED, located in the middle of the meterbridge,lights up when any input channel is programmed by dipswitchto have the CR MUTE/AIR TALLY dipswitch activated, andis also ON.
