24 channels of Flying Faders in 30"

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.

ACX Features
The Input Modules are 1.2” (30 mm) wide by 20 _” (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.
Screwdriver trim adjustments on each input
'B' Input Select with L.E.D.
Selects `B' line input.
Logic available on external connector to provide master selection of A or B inputs.
May be controlled by Flying Faders automation.
'Sum' Select with L.E.D.
Sums the `A' and `B' inputs after level trims, allows both inputs to be used simultaneously.
May be controlled by Flying Faders automation.
"Phase" Reverse Switch with L.E.D.
Applies polarity reverse to selected input.

Auxiliary Sends
Auxiliary sends 1 and 2 are post-fader.
Auxiliary sends 3 and 4 may be selected pre-fader.

Low Pass Filter
2nd order (12dB/octave)
In/out switch (jumper provided to include filters with EQ In /automation control).
Frequency range: 330 Hz – 20 kHz.

High Pass Filter
3rd order (18dB/octave)
In/out switch (jumper provided to include filters with EQ In /automation control).
Frequency range: 22 Hz - 1.5 kHz.

Equalizer
High frequency range: 1.5 kHz – 25 kHz.
15 dB boost/cut with detent at `0'.
Peak/Shelf switch, `Q' in peak position is 1.7.
Mid-high frequency range: 700 Hz - 15 kHz
15 dB boost/cut with detent at `0'.
Hi `Q' switch changes `Q' from 1.7 to 4.3.
Mid-low frequency range: 70 Hz – 1.2 kHz
15 dB boost/cut with detent at `0'.
Hi `Q' switch changes `Q' from 1.7 to 4.3.
