Automatic mixing controller with unbalanced analog audio inputs and outputs

The Model E-1A Automatic Mixing Controller helps professional audio mixers handle multiple live mics without having to continually ride their individual faders. This eight-channel (analog) or sixteen- channel (digital) signal processor patches into the input insert points of an audio mixing console.

It detects which mics are being used and makes fast, transparent cross-fades, freeing the mixer to focus on balance and sound quality instead of being chained to the faders. The Model E-1A's voice-controlled crossfades track unscripted dialogue perfectly, eliminating cueing mistakes and late fade-ups while avoiding the choppy and distracting effects common to noise gates.
  • Eliminates late upcuts
  • Reduces PA feedback and studio noise
  • Eight channels analog or sixteen channels digital
  • Dugan Control Panel for Java included
  • Channels may be grouped into three independent auto mixers Half-rack size " mount two in one RU
  • Link up to eight units for up to 128 channels
  • analog audio inputs: unbalanced, 6 kOhm, -22 to +4 dBu nominal level, +21 dBu maximum
    analog audio outputs: unbalanced, 100-Ohm source, drives a 600-Ohm load, +21 dBu maximum
    output noise: less than -91 dBu (A-wtd); 112 dBA dynamic range
