The Audio Tower - Euphonix CS3000 Operation Manual

Section 1: Introduction

The Audio Tower

Audio Tower
Audio processing for up to 56 faders
I/O Audio Module
Audio processing for 2 faders
1 - 4
faders worth of audio. Consoles above 56 faders have two Audio Towers; the
first houses the audio electronics for 48 faders, and the second for up to 56
faders, making a potential maximum of 104 faders. The bottom 4
channel slots in the first Tower of a 2-Tower system house the
bus link cards, which bridge the audio between the two Audio
Towers. The Master Audio Module resides in the bottom of the
first Tower while the Submaster Audio Module is in the second
Tower as its Master Section.
A single I/O Audio Module includes all the analog electronics for
2 faders or 1 channel strip. Each module also includes 2 equaliz-
ers, 2 variable input amps, 4 line input amps, 3 output amps, a
stereo/dual-mono direct output, a 6-into-1 Combiner (submixer),
4 aux send gain DCAs as well as the 2 stereo fader DCAs.
As audio goes through the channel, it passes from the patchbay
to an I/O Audio Module in the Tower, and back out again to the
patchbay and/or to the various buses that run within the Tower.
This is similar to a conventional console. What is different is
that all of the controls are located remotely in the Mix Control-
ler.
Great care has been taken in designing the circuitry to maintain
the highest possible integrity in the audio path. Wiring lengths
are kept to a minimum; digital control signals are kept clear of
audio signal paths; high-grade components are utilized; and
each stage of the signal flow has been optimized for low noise,
low distortion, and low crosstalk.
The result is an electronically well-managed audio control
system. Since all of the analog audio circuitry is in a remote
Tower, the Euphonix Mix Controller is sleek and compact, freeing
up valuable control room real estate. The remote location of the
Audio Tower also causes the system to generate
very little heat in the control room.
