D&R Airence USB Main Unit

Product information "D&R Airence USB Main Unit"


With the AIRENCE-USB ON-AIR 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, that can be used as a drop through in your furniture, houses all the vertically mounted input modules. 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.



This brand new AIRENCE-USB model has 4 balanced mic inputs (+48 phantom is standard) with inserts for signal processors, 6 stereo line inputs, 4x USB channels and 2x Telephone Hybrids. If you would like to call with VOIP we would advice to use the CISCO SPA112 as an interface between our 2 Telephone modules and the Internet.
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. 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.

High quality built in Hybrids with R and C balance and direct Talk back to the Hybrid channels makes conversation with callers very easy. Also by simply pushing the Cue button, conversation between DJ and caller outside the broadcast is of course possible.

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.  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.



The AIRENCE-USB has all the master controls such as 100 mm stereo master faders, stereo Aux send and return, monitor master with "follow phones" and a phones output with a split listen function.
