AIRMATE-USB

We designed the Airmate–USB to fulfil the requirements for a high grade low cost radio production mixer. Built
around well proven low noise circuitry, this console 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)
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..

FEATURES:
• 6 balanced Mic inputs with 3 band EQ and inserts for voice processors.
• 12 stereo line inputs where every line B input can accept our RIAA pre–amp pcb to work with
turntables..
• 2 USB stereo inputs (for radio play–out systems, such as our AIRCAST).
• 2 Telephone Hybrids built in with RJ 11 connectors for phones and land lines.
• Fader and On start on all 8 channels.
• ON–AIR light switching built in.
• Built in Talkback mic with routing to Clean–feed, Aux and/or Announcer outputs.
• Auto Control Room Monitor cut when in DJ mode.
