What type of wire do you recommend for analog and digital audio?

Any modern installation will benefit by using digital audio wire exclusively for all analog and digital connections. Cable designed for digital audio has low capacitance, tight twist tolerances, and provides superior performance compared to analog cable.

What gauge of wire should I use with my D-sub 25 connectors?

The factory supplied crimp style AMP DB-25 mating connectors (Amp part number 1-745496-8) are designed for 26 to 22 AWG wire.

What kind of punch blocks should I use for my digital audio installation?

We recommend Krone 50 pair termination blocks – model 6652-1-880-10.

Be sure to wire the blocks in a pattern of Pair 1 H-L-SH, Pair 2 SH-H-L, Pair 3 H-L-SH, etc., to take advantage of the built in patch and test point cables manufactured by Krone.

How do I wire an unbalanced analog output to a balanced analog input?

Wire the unbalanced Hi to the balanced Hi, unbalanced Shield to the balanced side Lo and Shield.

How do I connect an unbalanced DIGITAL (SPDIF) CD output to a balanced AES input?

We suggest using a "balun" or format converter if possible, but if not available you can try connecting the CD (+) to AES in HI (+), connect CD (-) to AES in LO(-). Leave the AES input’s Shield connected at the console/card end only. This works because all of our AES inputs are transformer coupled. The impedance is not correctly matched, but this method will work in a pinch. The AES receiver will ignore the copy protect (SCMS) bit.

How do I connect a balanced AES digital console output to an unbalanced (SPDIF) input?

You must use an external AES to SPDIF converter.

Do I need to use a telephone hybrid with the phone module?

Yes. Phone modules are designed to interface via balanced analog line level connections to an external telephone hybrid. They are NOT intended to interface directly with the phone line. Doing so can result in damage to the console.

Where can I find phone module application information?

Please see our white paper, "Making The Connection".

How do I use the channel ON tallies from my three mic channels to make my ON Air light come on whenever any of three mics are on?

To do it this way with some consoles you need to add diodes in what is commonly called a wired-OR configuration. The orientation of the diodes will depend on the polarity of components and/or voltages in the external circuitry. But this is generally not necessary. On most of our consoles you can set the CR mute function for the desired mic channels and then wire your ON AIR light to the console’s ON AIR TALLY output, following the console-specific instructions as outlined in the console’s manual.

Do I need to use an external DC power supply when wiring logic connections?

In most cases the answer is no. On many Audioarts consoles the logic circuits are opto-isolated for maximum protection. But in most cases +5VDC and digital ground are provided on the logic connector. Refer to the manual for your specific console model for details..

What size UPS should I buy for my console?

See the suggested UPS rating for your Audioarts Engineering product as shown in the table below. Note that these ratings are based on the maximum configuration for the product. Your product may be short loaded or draw less power than shown in the table.

How do I wire the molex pins?

Molex pins have a pin#1 mark.

Pin1 = HI, Pin2 = SH, Pin3 = LO.

Looking at the back of the unit, the right side of the molex connector is Pin1 (left to right as seen from behind the unit is LO, SH, HI). One nice benefit of this arrangement is that if you have an out of phase signal (high and low are reversed) you can unplug the connector, rotate 180 degrees, and reconnect it.

Only half of the outputs are working. How do I get the rest to work?

This unit must have molex jumper cables installed from connector A to connector B and from connector C to connector D on the rear to get all outputs to follow the A (left) and C (right) inputs.

How do I configure this for mono? For stereo?

See our documentation for configuring the 8400.

How do I increase the number of mic channels?

The Air 1 has two microphone inputs that directly feed the first two faders. These two mic channels can be used to mute the monitors and activate the ON AIR TALLY output and the meter bridge ON AIR indicator. You can always connect additional mics by using external mic preamps, but these additional mic inputs will not control the mute or tally functions.

How do I hook up a phone to handle callers?

The Air 1 console does not have dedicated phone caller inputs. If you need to handle callers with this console, please see our white paper "Making The Connection".

end faq

How do I get my mic channels to work?

The Air 2+ has connections for two microphone inputs, which are the inputs to two internal microphone preamps. The mics are wired to these connectors as indicated in the product manual. You must then use an RCA Y-adapter cable to connect a microphone preamp output to the left and right inputs of the channel (fader) you want that microphone to be controlled by. Do the same thing with the other mic.

How do I increase the number of mic channels?

The Air 2+ has two microphone inputs that have some dedicated features. Mic 1 is used as an operator mic and is the talkback source when talking to a caller off line or when talking to the studio output. Mic 2 is used as a studio mic and can use an external user-supplied switch to provide a talkback function to the control room, allowing talent in the studio to talk to the board operator via the console cue system. You can always connect additional mics by using external mic preamps, but these additional mic inputs will not provide any of the special functions provided by Mic 1 and Mic 2.

Can I have more phone (caller) inputs?

The Air 2+ console has one dedicated phone caller input. If you need to handle additional callers with this console, please see our white paper, "Making The Connection".

How do I set up talkback from the control room to the studio?

The Mic1 signal feeds an internal talkback bus. The audio on this bus interrupts the studio output when the studio TB button on the console is pressed.

How do I set up talkback from the studio to the control room?

The Mic2 signal is put into CUE when an external user-supplied switch, connected to pins 11 and 12 of the console's DB-25 rear panel connector, is pressed. The operator can then hear Mic2 over the console CUE system.

How do I talk with the caller off line?

The Mic1 signal feeds an internal talkback bus. The audio on this bus interrupts the caller feed output when the caller TB button on the console is pressed.

Is the remote on logic signal present as long as the channel is on?

No, it is only present when the On/ Off switch is held while turning the channel on. It is not present when turning the channel off.

end faq

My clock display is no longer illuminating. What can I do?

This can happen with one particular clock/timer module in use in some Audioarts Engineering consoles. This clock/timer module can be identified by the presence of a large green electrolytic capacitor and two adjacent four position dipswitch assemblies. With the console power on, locate the four position dipswitch labeled SW3. Locate position 2 of that switch. Turn the switch on, leave it on for one or two seconds, then turn it back off again. The clock should now be blinking 12:00:00, awaiting the normal time set procedure.

What's the first step I have to take to program functions for the D-16?

You have to enter Configuration Mode. The directions for this are in the owner's manual.

How do I change the displayed name for a signal?

After entering Configuration Mode, follow the instructions in the owner's manual for editing names.

How do I get Mic3 and Mic4 to work?

After entering Configuration Mode, set the value of attribute 3 of the Line 10 ST signal to “M” to configure Line 10 as two independent mono inputs.

How do I increase the number of mic channels?

The D-16 is designed to handle up to four microphone inputs. Two factors are involved in this setup. First, the console has four mic preamp sections; wire the mic to a mic pre input, then wire that mic pre output to an analog input. We have provided two special line inputs for this purpose, Line 9 and Line 10. Each of these line inputs can be programmed in Configuration Mode as either a single stereo input or two independent mono inputs. Line 9 is factory configured as two mono signals, Mic1 and Mic2, while Line 10 is factory configured as one stereo signal. Configuration is required to use Line 10 as two mono signals (Mic3 and Mic4) – see the answer to the question “How do I get Mic3 and Mic4 to work?”

You can always connect additional mics by using external mic preamps and connecting them to a normal console stereo input that is not configurable as two mono inputs. You would have to Y your connection to both left and right sides of the stereo input. Any of the inputs on the console can use the mute and tally logic functions.

Can I have more phone (caller) inputs?

The D-16 console has two dedicated phone caller inputs. If you need to handle additional callers with this console, please see our white paper Making The Connection.

How do I set up talkback from the control room to the studio?

Any D-16 fader can be set up in Configuration Mode to feed the internal talkback bus. The audio on this bus interrupts the studio output when the studio TALKBACK button on the console is pressed.

How do I set up talkback from the studio to the control room?

Any D-16 fader with an assigned logic port is put into CUE when an external user-supplied switch, connected to pins 6 and 18 of that fader's DB-25 logic connector, is pressed. The operator can then hear that fader's audio over the console CUE system.

How do I talk with the caller off line?

With the phone channel turned off, press the PH button at the top of the phone channel. Dial up a source (this can be an input or it can be a bus) with the SOURCE SELECT knob. When the desired source is found, press ENTER. Now, whenever the phone channel is off, the caller(s) will be fed the selected source. If the source was a console bus, then all audio on that bus is fed to the caller(s) when the phone channel is off.

Where is the EXT input, as used for Off Air monitor?

There is not a pre-named input called EXT. You simply need to select one of the inputs and designate it as such. Give it an easy to identify name, such as AIR.

end faq

I have crosstalk and/or distortion issues involving only some inputs. Why?

The D-70 console employs a non-summing talkback bus, fed by the pre-fade audio of any mic input that is configured to feed the bus. Since the talkback bus is non-summing, feeding it from multiple mic inputs causes crosstalk and/or distortion on all mic channels so assigned. You must choose only one mic channel to feed the talkback bus.

How do I increase the number of mic channels?

The D-70 console rear panel cards determine if a fader is a mic input, an analog line input, or a digital line input. To add mic channels, replace a line input card (analog or digital) with a mic input card. The VDip application must then be run to configure the slot as a mic channel.

How do I set up talkback from the control room to the studio?

Any single D-70 mic input can be set up to feed the internal talkback bus by installing a jumper at position J2 on the MMADC input card, located in the rear of the console. The audio on this bus interrupts the studio output when the studio TB button on the console is pressed. A TB level control allows you to adjust the volume of the talkback signal. Please note, only one mic channel in the console may be assigned to the talkback bus.

How do I set up talkback from the studio to the control room?

Any D-70 mic input is put into CUE when an external user-supplied switch, connected to pins 2 and ground (pin 7, 8, or 12) of that mic channel’s logic connector, is pressed. The operator can then hear that mic’s audio over the console CUE system.

How do I talk with the caller off line?

Any single D-70 mic input can be set up to feed the internal talkback bus by installing a jumper at position J2 on the MMADC input card, located in the rear of the console. The audio on this bus interrupts the caller 1 feed when the caller CUE1 button on the console is pressed and it interrupts the caller 2 feed when the caller CUE2 button is pressed. Please note, only one mic channel in the console may be assigned to the talkback bus.

How can I get the Tally for my On Air Light to work with buses other than PGM?

The Air Tally relay does not fire unless the channel is on and assigned to PGM. If you want the tally to fire when the channel is on regardless of any bus assignments, use Tally 2 or Tally 3 instead of the Air Tally.

All the lights on the console are flashing. The power supply appears ok and reboot didn’t fix it. What should I look for next?

Check on the PR-70 motherboard that the Master Clock crystal (Y1) is properly seated in its socket.

I removed a front panel module, and when I put it back in all the lights are flashing on it. What would cause this?

Check to see if the ribbon cable from the module is plugged in backwards on the motherboard.

Can I have more than one SPD-70 (phone module) in the console?

No. The bus structure only supports one dual caller module. If you need to handle additional callers, please see our white paper Making The Connection (pdf). [LINK THIS]

When I run VDip, the first available slot is #9 (or #17), not #1. Why is that?

This is normal. The D-70/20 frame is 8 slots less than a full 32 input frame, so the first slot is 9. The D-70/12 frame is 16 slots less than a full 32 input frame, so the first slot is 17.

VDip is not connecting.

Be sure you've followed the parameter settings in the manual.

Check that the interface cable is correct.

Check that the local/remote switch on the console is set to remote (the switch is lit).

end faq

I installed an SP-75 and all the lights are flashing. Why?

The module must be installed in its dedicated slot, which is just to the left of the OM-75 module. If the module is installed in any other normal input slot, all its lights will flash to indicate it is improperly installed.

I installed an SP-75 and all the lights are always on no matter what buttons I push. Why?

The module must be installed in its dedicated slot, which is just to the left of the OM-75 module. If the module is installed in one of the utility slots to the right of the SC-75, all its lights will stay on and it will be unable to respond to any of its buttons.

I added an IN-75 and all the lights are always on no matter what buttons I push. Why?

Input modules can be installed in any of the slots to the left of the OM-75 module. If the module is installed in one of the utility slots to the right of the SC-75, all its lights will stay on and it will be unable to respond to any of its buttons.

I moved my OM-75/CR-75/SC-75 and all the lights are flashing. Why?

These modules must be installed in their respective dedicated slots. Because of their unique edge connector configuration there are only three console slots the modules will fit in. They must be installed in the proper order in these slots. Starting from the left of the three slots, the proper module order is OM-75, CR-75, and SC-75. If any of these modules is installed in the wrong slot its lights will flash to indicate it is improperly installed.

I have one SP-75 module. Can I have more phone (caller) inputs?

The D-75 will only support one SP-75 module, which can handle two callers. If you need to handle additional callers, please see our white paper Making The Connection.

I can hear my mics in UTIL even when they’re supposed to be off. Can I change this?

The console comes from the factory with the UTIL bus configured to be fed pre-fade and pre-on by all inputs, except the caller inputs. This feature can be defeated by switching position 4 of the four position dipswitch on the PR-75 board, found in the console’s meterbridge area.

How do I increase the number of mic channels?

The D-75 console has an internal four channel QMP-4 mic preamp card. Mics are connected by wiring the mic to one of the QMP-4 inputs and wiring the corresponding QMP-4 output to an IN-75. A second QMP-4 can be added to allow the use of up to eight mics. If additional mics are needed beyond eight, external mic preamps must be used.

How do I set up talkback from the control room to the studio?

Any D-75 input can be set up to feed the internal talkback bus by turning the channel’s TB TO STU dipswitch on (dipswitches are located at the top of the module, underneath the hinged meterbridge). The audio on this bus interrupts the studio output when the studio TB button on the console is pressed. A TB level control allows you to adjust the volume of the talkback signal.

How do I set up talkback from the studio to the control room?

Any D-75 input is put into CUE when an external user-supplied switch, connected to pins 17 and 19 of that channel’s DB-25 connector, is pressed. The operator can then hear that channel’s audio over the console CUE system.

How do I talk with the caller off line?

Any D-75 input can be set up to feed the internal talkback bus by turning the channel’s TB TO STU dipswitch on (dipswitches are located at the top of the module, underneath the hinged meterbridge). The audio on this bus interrupts the caller 1 feed when the CUE CALLERS 1 button on the console is pressed and it interrupts the caller 2 feed when the caller CUE CALLERS 2 button is pressed.

end faq

Does the console have a mono out?

Yes. It is the TEL bus.

How can I feed a mic signal to the caller for off line communication?

The R-5 has a mono balanced EXT input that feeds the TEL bus. Since the caller is fed from the TEL bus, the EXT input provides a nice way to route a specific audio signal to the caller. A good candidate for feeding EXT is the insert out of the console operator's mic channel. Note that if you are using a mic channel insert for external processing you have to defeat the internal insert point jumper, but this does not have to be done if you are just using the insert output to feed the EXT input.

How do I increase the number of mic channels?

The R-5 has two microphone inputs that directly feed the first two faders. These two mic channels can be used to mute the monitors and activate the ON AIR TALLY output. You can always connect additional mics by using external mic preamps, but these additional mic inputs will not control the mute or tally functions.

The R-5 only has one caller channel. Can I have more phone (caller) inputs?

If you need to handle additional callers, please see our white paper Making The Connection.

How do I set up talkback from the control room to the studio?

Either R-5 mic input can be set up to feed the internal talkback bus by wiring a jumper between pins 1 and 2 of that channel's logic connector. The audio on this bus interrupts the studio output when the studio TB button on the console is pressed. Please note, only wire this jumper on one of the two mic channels, not on both.

How do I set up talkback from the studio to the control room?

Either R-5 mic input is put into CUE when an external user-supplied switch, connected to pins 7 and ground (pin 10 or 11) of that channel's logic connector, is pressed. The operator can then hear that channel's audio over the console CUE system.

How do I get inside the console to change parts?

You must remove the bottom cover.

end faq

When I turn a mic channel on or off the ON and OFF button lights change to reflect this, but on line channels the buttons don't light. Why is that?

The line inputs of the R-16 (and the earlier R-10) do not have channel on/off logic. The switch contacts are brought out to provide start and stop functions to external machines, and the switch LED contacts are also brought out so that an external machine can light the buttons. Please note that the button LEDs are not normally loaded from the factory.

How do I hook up a phone to handle callers?

The R-16 (and the earlier R-10) do not have dedicated phone caller inputs. If you need to handle callers with these console, please see our white paper Making The Connection.

end faq

I have one SPN-55/SPN-55e module. Can I have more phone (caller) inputs?

The R-55 and R-55e consoles can support more than one SP-55(e) phone module. However, there will be no conferencing between the multiple callers. In other words, the callers will not be able to hear each other. If you want to handle multiple callers and need them to be able to hear each other you will have to set up conferencing outside of the console. For additional information see our white paper Making The Connection.

How do I increase the number of mic channels?

The R-55 and R-55e consoles have an internal four channel QMP-4 mic preamp card. Mics are connected by wiring the mic to one of the QMP-4 inputs and wiring the corresponding QMP-4 output to an SL-55 or SL-55e. A second QMP-4 can be added to allow the use of up to eight mics. If additional mics are needed beyond eight, external mic preamps must be used.

How do I set up talkback from the control room to the studio?

Any SL-55 / SL-55e input can be set up to feed the internal talkback bus by turning the channel's TALKBACK dipswitch on (dipswitches are located at the top of the module, underneath the hinged meterbridge). The audio on this bus interrupts the studio output when the studio TB button on the console is pressed. A TB trimpot just below the CRS-55/CRS-55e (or SS-55/SS-55e) dipswitches allows you to adjust the volume of the talkback signal.

How do I set up talkback from the studio to the control room?

Any SL-55 / SL-55e input is put into CUE when an external user-supplied switch, connected to pins 17 and 19 of that channel's DB-25 connector, is pressed. The operator can then hear that channel's audio over the console CUE system.

How do I talk with the caller off line?

Assign both the desired mic and the caller to PRE. This results in the mic signal being fed to the caller. Put the caller in CUE to hear the caller on the console cue system.

end faq

Cue audio failed. Is there a most likely suspect component?

U13 (on most revisions of the CR-60 module). This component failure is often a result of hot plugging or unplugging the CR-60 module.

Can the SP-60 module be made to allow for multiple bus selection like the IN-60 modules can?

Yes, contact our parts department to order the JAGX chip, which defeats the electronic interlock of the buses on the SP-60 module.

I have one SP-60 module. Can I add another SP-60 to handle a second caller?

No. The bus structure of the console does not lend itself well to installing two SP-60 modules. If you need to handle additional callers, please see our white paper Making The Connection.

I have crosstalk and/or distortion issues involving only the left side of some channels. What’s causing this?

The R-60 console employs a non-summing talkback bus, fed by the left side pre-fade audio of any input that is configured to feed the bus. Since the talkback bus is non-summing, feeding it from multiple inputs causes crosstalk and/or distortion on all inputs so assigned. You must choose only one input to feed the talkback bus. This is accomplished with position 7 of the module’s seven position dipswitch.

How do I increase the number of mic channels?

The R-60 console has an internal two-channel DMP-60 mic preamp card. Mics are connected by wiring the mic to one of the DMP-60 inputs and wiring the corresponding DMP-60 output to an IN-60. A second DMP-60 can be added to allow the use of up to four mics. If additional mics are needed beyond four, external mic preamps must be used.

How do I set up talkback from the control room to the studio?

Any single R-60 input can be set up to feed the internal talkback bus by turning the channel’s TB TO STUDIO dipswitch on. The audio on this bus interrupts the studio output when the studio TB button on the console is pressed. Dipswitches are located on the individual IN-60 module circuit boards - position 7 is TB TO STUDIO. Please note, only one channel in the console may be assigned to the talkback bus.

How do I set up talkback from the studio to the control room?

Any R-60 input is put into CUE when an external user-supplied switch, connected to pins 9 and 12 of that channel’s logic connector, is pressed. The operator can then hear that channel’s audio over the console CUE system.

How do I talk with the caller off line?

Any single R-60 input can be set up to feed the internal talkback bus by turning the channel’s TB TO STUDIO dipswitch on. The audio on this bus interrupts the caller feed when the caller COM button on the console is pressed. Dipswitches are located on the individual IN-60 module circuit boards - position 7 is TB TO STUDIO. Please note, only one channel in the console may be assigned to the talkback bus.

How do I get my mic channels to work?

The W-12 has connections for two microphone inputs, which are the inputs to two internal microphone preamps. The mics are wired to these connectors as indicated in the product manual. You must then use a Y-adapter cable to connect a microphone preamp output to the left and right inputs of the channel you want that microphone to be controlled by. Do the same thing with the other mic.

How do I increase the number of mic channels?

Although the W-12 has only two microphone inputs using internal preamps, you can always connect additional mics by using external mic preamps. Only the first four fader channels can be assigned to studio talkback, so operator mics would need to be on one of these four faders.

Can I have more phone (caller) inputs?

The W-12 console has one dedicated phone caller input. If you need to handle additional callers with this console, please see our white paper Making The Connection.

How do I set up talkback from the control room to the studio?
