We designed the D&R Airmate 12 USB on-air mixer to fulfil the requirements for a high grade low cost radio production mixer. Built around well proven low noise circuitry, the Airmate is the reliable workhorse for the self-op production D.J. that needs an internal Telephone Hybrid (2x) and 2x USB connection to the PC (e.q. for streaming to the web)
 
Now available with an optional Bluetooth module
 
A heavy duty 19" rack mounted RF shielded chassis houses 8 vertical triple input modules giving flexibility rarely found in a mixer of this type. Six input channels with high quality balanced microphone inputs on XLR and two stereo line level inputs on Cinch (RCA) connectors. And… every line level line B input can be converted into a phono (gramophone) channel by simply fitting an optional stereo R.I.A.A. equalized phono pre-amp. On top of this we have added 4 Mic inserts for processing equipment.
 
The Airmate-12 model has 10 balanced mic inputs with +48 phantom with insert,12 stereo line inputs, 2 USB and 2 Telephone Hybrids. 
Channel 5 and 6 have Mic/Line and USB interface to transfer audio from and to your PC.  Channel 7 and 8 have, apart from the stereo line input, also RJ-11 connectors to interface with a old fashioned POT and a Telephone appliance to dial the number you want to reach.
​
High quality built in Hybrids and direct Connection and Talkback buttons in the Hybrid channels makes a conversation with listeners very easy. 
With the Telco Send (level to the caller) and Telco Gain (level coming from the caller) all levels can be easy adjusted. Fader start can be from the ON switch or FADER. Fader start also switches on ON-AIR lights.
 
There is a 3 band Equalizer on channel 1-10. The stereo Aux send can be set pre or post fader. All mic inputs have low cut jumpers. A clean feed send is available for external analog and digital Hybrids.
 
 
On the back panel you can find two USB connectors to control your USB channels by your computer.
Very simple; your computer will see a new USB device when connecting the Airmate-12 on the moment you connect the unit to your computer.
​
It's also possible to include VoIP channel(s) inside the Airmate-12 in stead of the standard POT channels. In that case you will get an USB connector on the place of the RJ11, so you can connect your VoIP channel by your computer with any VoIP software. All in and output connections are on standard XLR / Cinch and Jack connectors.
 
We can offer an optional AES/EBU digital output on XLR's. The left XLR output carries the stereo AES digital output signal and the right XLR is a stereo digital input. The analog audio signal is always available on the 2 jacks above the left digital XLR output.
 
It's also possible to add on all eight channels of your Airmate-12
unit our RIAA pre-amp board.  This will give you the option to connect the old fashion record player to the mixer, so good old times can come back to live on a new day piece of broadcast equipment.
​These boards can be purchased also at a later time and are very simple to connect inside the mixer on one of the boards by yourself.
 
We now have dedicated VoIP channels available for the Airmate-12, or a combination of one TELCO module and one VoIP module. If you still want to use a classic analogue or digital Hybrid we have designed a cleanfeed output on pin 1-4 of the RJ11 connector. You can return the Hybrid signal on the line input of the VoIP module.
