AUDIOARTS AIR-1
8 CHANNEL ANALOG RADIO MIXER

A True Broadcast Console…in a Tiny Package

Conserve studio space, not studio capability. The AIR-1 is our most capable standalone console in a compact footprint yet. It fits anywhere your laptop computer does for on-air, production, podcasting or remotes. The Audioarts AIR-1’s proven design has become the number one choice for small studios and production rooms due to its compact footprint, professional features, and attractive price. Now, with a USB interface, this same small console is able to send and receive audio from devices such as digital audio workstations, playout systems, and automation systems.

The AIR-1 is ideal for remotes, small on-air studios, web streaming, production, or any situation where a compact, low-cost, highly capable radio console is needed.

The AIR-1 covers all the basics: two mic inputs, six stereo line inputs, two program busses, a flexible metering and monitoring section usually found only in larger boards, cue output, muting, and a built-in headphone amp.

Small, so it can easily be used in a tight space such as a news or voice tracking booth, or on remotes. Rugged, built to Wheatstone/Audioarts’ usual high standards to last and last.

AIR-1 is surprisingly inexpensive, so it fits any budget. You don’t have to give up features or scrimp on the quality you need. Sometimes a powerful, compact broadcast console is exactly what you need. The Audioarts AIR-1 is it.

Features

• USB Interface
  Send/receive connection to digital audio workstations, playout systems and automation systems
• Low Profile Compact Design
  Only 15”/39cm wide to conserve studio space.
• Long-Throw Faders
  On input channels, monitor output and headphone output.
• Two Mic Input Faders
  Extremely high-performance mic preamps – noise level just 1dB short of the theoretical limit – with enough headroom to handle the most enthusiastic voice. Continuously variable gain trims to precisely match your microphones.
• Six Line Input Faders
  True differential electronically balanced inputs, not a semi-pro unbalanced input that merely accept balanced signals.
• Two Program Buses
  Full balanced broadcast standard, switchable stereo or mono. For remote applications, use PGM 1 for the feed to the station, PGM 2 for the house monitors or phone mix-minus.
• External Input
  Feeds the monitor section for listening to live air or talkback from the studio.
• Monitor Output
  Front panel long-throw fader. Switchable PGM 1, PGM 2 or EXTernal; can mute when MIC 1 and/or MIC 2 is on.
• Headphone Output
  Front panel long-throw fader. Built-in powerful headphone amplifier.
• Cue Output
  Provides preview to an optional external cue speaker amplifier. Can be set to automatically interrupt your main stereo monitors.
• Split Cue
  Switchable separately for speaker and headphone. When any fader is in CUE, sends CUE audio to the left channel, L+R sum of the selected monitor source to the right channel. Very useful in remotes for sending local program to one ear of the talent, talkback from the studio to the other ear.
• Switched Meter
  PGM 1, PGM 2 or EXTernal input.
• Solid State Leds
  On all switches so you never need to replace burned-out bulbs. External In-Line Power Supply for hum free, cool reliable operation.
• On-Air Light
  Front panel LED between the meters, and a relay output to drive an external ON AIR light. Activates when a mic channel is ON and enabled for monitor mute.

Bottom-mounted dip switches for easy programming

MONO SUM
PGM outputs can be stereo or mono sum

INPUT LEVEL
LINE and EXT input can be set to +4dBu (broadcast professional standard) or –4dBu (consumer)

MONITOR MUTE
Mic inputs
can mute monitor speaker when mic channel is turned on (prevent control room feedback)

SPLIT CUE
Sends CUE to the left channel, L+R sum of the selected monitor source to the right channel

CUE TO MONITOR
When on, any source in cue will interrupt the monitor speakers, similar to solo
