With the D&R Airence USB Mixer mixer you can own a modern, split version type of radio production mixer. A smart mixer with an integrated USB based control section.
 
The Airence-USB model has 4 balanced mic inputs (+48 phantom is standard) with inserts for signal processors, 6 stereo line inputs, 4 USB channels and 2 Telephone Hybrids (or VoIP channels).
Fader start generates in the Mic mode a Mic-on signaling to switch ON-Air lights. There is a 3 band Equalizer on channel 1-4 and on all 6 Triple input channels of the Extender Unit. The stereo Aux send can be set pre or post fader. All high quality low noise mic inputs have low cut jumpers.
​One physical USB connection interfaces 4 stereo audio channels from and to your PC plus all (programmable) remote controls on the right hand section of the mixer. 24 illuminated (green/red or yellow) switches can be used to control functions in your Radio Automation such as starting jingle machines and switching between live and NON stop. Recording a voice track while ON-AIR is also one of the possibilities. 
 
​The illuminated front panel ON switch is electronically attached to the built in mechanical fader start enabling selection of a play-out start either by fader or via the ON switch. 
On the back panel of the Airence Main unit you will find the Power Supply input. This is a 5 pin XLR connector with also a possibility to connected a second redundant Power Supply to your unit. In case of choosing for the AES Output option, this redundant Power Supply XLR connector will be used for the AES Output XLR.
 
​Also you can find the USB connector to control your USB channels and the Control Panel by your computer. Very simple; your computer will see a new USB device when connecting the Airence Main unit to your computer. Further configuration can be done by the software included at the unit.
By using the Extender Unit, you can very easily connect both units by using the 15P-Sub-D cable that will be included inside the package of the Extender device. Please be informed that both units always needs to be powered OFF by connecting them to each other. All in and output connections are on standard Jack / Cinch and XLR connectors.
 
Extender Unit
If more inputs are needed, you can purchase the Airence-EXT(ender) unit and instantly you have 6 more triple inputs with each giving you a low noise Mic and 2 stereo line inputs under control. Line level B can be converted into a Phono pre-amp by way of the optional RIAA preamp that can be ordered as an option.
​You can install as many Airence Extender units to your Airence Main as needed. All units are easily connected with each other by an included 15P Sub-D connector. 
 
VoIP
You can order the Airence-USB main unit with built in VoIP channels on position 5 and/or 6 or even a combination of 1x Telco and 1x VoIP. Telco/VoIP Channel 5 and 6 have, apart from the stereo line input, also RJ-11 connectors to interface with an analogue telephone line and a common dial unit. And in case a VoIP module is installed one of the RJ-11 is replaced by 1x USB connector, the other RJ-11 has a clean-feed signal on pin 1 and 4. Both analogue high quality built in Hybrids with R and C balance have direct Talk back to the Hybrid channels to make  conversation with callers very easy.  This is also possible when VoIP modules are built in. Also by simply pushing the Cue button, conversation between DJ and caller outside the broadcast is of course possible.
​THIS OPTION NEEDS TO BE MENTIONED BEFORE YOUR PURCHASE AND WILL BE ONLY AVAILABLE FOR AIRENCE MAIN UNITS THAT HAS BEEN PRODUCED WITH SMD-COMPONENTS.
AES output
It's also possible to add an optional AES output with a 3 pole XLR male connector inside the Airence Main unit. The AES output replaces the second 5 pole redundant XLR in that case.
THIS OPTION NEEDS TO BE MENTIONED BEFORE YOUR PURCHASE.
 
RIAA pre-amp
It's also possible to add on all six channels of your Airence Extender 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 date and are very simple to connect inside the mixer on one of the boards by yourself.
**ONLY BE ADDED INSIDE THE EXTENDER UNIT**
 
 
Power supply
Every Airence unit, Main and Extender, is individually powered by a 12V switched mode power supply. A power supply redundancy is an option with the optional extra power input connector. When you choose this as an extra option, you cannot include the AES Digital Output option anymore inside your Airence Main unit.
 
Metering Software 
The Airence sends out control signals over USB, based on the HID protocol. This also means that the main output signals can be displayed on a TFT screen in a beautiful meter application. Both Program and Sub stereo signals are shown on a high resolution PPM. A smaller separate stereo meter on the right hand side of the meter application shows all signals heard through the CRM speakers. At the same time this software application shows you a professional looking Radio clock that is synchronized with your local PC.
