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 (analogue) 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.

Features:

  • Eliminates late upcuts
  • Reduces PA feedback and studio noise
  • Eight channels analogue 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
