Just Mix
Bigger Projects With Your Flying Faders System
Stop turning away
bigger projects because space is at a premium in your
control room. Add additional outboard channels that are
totally integrated with your console's multitrack,
stereo, aux and solo buses and your Flying Faders
automation system. And ACX won't compromise the sound of
a classic Neve or API console.
ACX was designed
from the ground up for you. Compact in size, yet generous
in features and performance, ACX is a whole new category
of audio console product. Add up to 32 channels with not
only automated faders, but also dual line inputs,
equalization, filters, 4 aux sends, 8 buses, stereo
panning, direct outs, inserts, solo and mute. And, as a
special feature, both line inputs can be on
simultaneously, creating dual summed inputs with trims on
each channel for 48 active inputs. As an option, the
events control facilities of Flying Faders can be used to
automate the input select, input sum, EQ and insert
functions.
ACX is a 16, 24 or
32 input, 8-bus console expander with fader and events
automation. Measuring less than 30 inches wide for the
24-channel version and only 32” from front to back,
ACX packs a lot of punch into a small space. The frame,
plug-in modules and motherboards are designed for
durability and serviceability, and the high-quality audio
circuitry features balanced inputs, outputs and even
balanced summing buses throughout.

_” (515 mm) long with the following functions:
All inputs, outputs and summing buses are balanced.
Output Assign 1 - 8
Provides assignment to 8 balanced mix buses.
Stereo Pan
MIX button connects pan pot to Stereo Mix Bus
POST button enables odd/even panning between bus pairs
(bus buttons are `post pan')
Input Level Trims
Provide separate +/- 10dB level trim with center detent
for both A and B inputs.
