AIRENCE-USB a new Radio power package


With the Airence-USB mixer you can own a modern, split version type of radio production mixer.

A smart mixer with an integrated USB based control section. Built with well proven low noise circuitry, this console is the reliable workhorse for the self-op production D.J. 

Built in Telephone Hybrids (2x), 4 channels USB and 4 Mic inputs. Ideal for streaming to the web and sending and accepting 4 stereo channels from your Play-out software.

A heavy duty (19" rack) RF shielded chassis drops into  your furniture and houses all the vertically mounted input modules with K-Alps faders.

Extension units with six triple input channels with high end quality Mic inputs on XLR and two stereo line level inputs on Cinch (RCA) connectors can be connected to the main unit.

The result is a modern split drop through 12 (or 18/24) fader radio console.


- Unlimited numbers of inputs

- Split version design

- Program and Sub busses

- USB control section included

- Studio, Announcer and Phones outputs

- Bi directional Cue communication buss

- Two Hybrid or VoIP channels built in

- Power Adapter included

the channels

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.


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.

If you would like to call with VoIP with the TELCO modules we would advice to use the CISCO SPA112 as an interface between our 2 Telephone modules and the Internet.

And in case you have an ISDN connection in your situation, we advice to use the Fritz Box type 7390 to convert the ISDN into an analog line that can be connected directly to the Telco modules of the Airence mixer.


AES output option

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.

control section

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. 

back panel

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.

RIAA pre-amp option

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 board can be purchased also on a later moment inside our radiowebshop and are very simple to connect inside the mixer on one of the boards by yourself.



Every Airence unit, Main and Extender, is individually powered by a switched mode power supply.

A power supply redundancy is an option with the optional extra power input connector.

When choose this as an extra option, you cannot include the AES Digital Output option anymore inside your Airence Main unit.

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. 

Just for safty; always switch OFF your consoles, before you will connect a new Extender device on your Airence Main unit.


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.

A software program is included in the delivery for programming

the Control section. (Airence Virtual Keyboard Mapper)

All software can also be downloaded on our Wiki-page, where we always included the new up-to-date versions.
