Dan Dugan Model E-1A Automatic Mixing Controller
MPN #MODEL-E-1A
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.
