Overview
Audioarts AIR-4, 12 Channel Analog Console
The AIR-4 has four microphone preamps built in. This allows the use of a host microphone and three guest microphones with the AIR-4 without the use of any external mic preamps. It gives you 12 input faders (w/A-B source select), a 13th fader for call-ins, external machine control, two program busses, built-in cue speaker and CR, headphone and studio monitoring control. Add patchable USB connectivity for PC news, production work stations or streaming audio, and the Audioarts AIR-4 is perfect for local radio stations and internet broadcasters.
The AIR-4 design utilizes top grade components and circuits for superb performance. With basic features like machine control, cue, talkback, and mix-minus included, it’s perfect for smaller stations looking to upgrade as well as for larger facilities in need of an auxiliary studio or newsroom console.
The Audioarts AIR-4 mixing console draws upon Wheatstone Corporation’s continuing investment in the latest design, tooling, and manufacturing infrastructure. Because we both design and manufacture our own audio consoles, right here in New Bern, NC, USA, we can ensure our reputation for unparalleled quality, performance, and reliability.
The AIR-4 delivers superb broadcast quality and an excellent feature set at a great value.
