S-4000S Digital Snake System

The digital audio transmission system
(Digital Snake) shall be a modular system

that can be congured in groups of 8
channels up to a maximum of 40 channels
per transmission cable. The system shall
consist of one Input or Stage Box Module,
with XLR or AES/EBU inputs, as well as
the option for multiple line-level “returns” or
Outputs. It will also consist of at least one
Output or Front-of-House (FOH) Module
that will have line level outputs as well as
the option for some line level inputs or
returns.

The modularity shall allow for different
congurations of the Input Module or Stage
Box including 40 inputs and 0 outputs, 32
inputs and 8 outputs, or 24 inputs and 16
outputs. The transmission cable between
the Input or Stage Box Module and the
Output or FOH Module(s) shall be a Cat5e
or Cat6 cable.

The inputs shall be of very high quality
and accept both line and microphone level
inputs with individually selectable phantom
power. The input gains or trims for the
inputs as well as their phantom power
settings, shall be remotely controllable from
the Stage or FOH Module using either a
hardware remote control unit or a computer.

The gain level shall be controllable in 1 dB

steps. The system shall also offer at least 10
preset memories of different congurations
of the input gain and phantom power
settings.

The audio protocol for a 40-channel system
shall have a 96 kHz sampling rate, provide
24-bit audio, and have a protocol latency of
375 microseconds from the stage unit to the
FOH unit. The system shall have redundant
Ethernet ports allowing the connection of
two Cat5e or Cat6 cables from the Input
unit to the FOH unit. The system shall be
designed to switch automatically from one
cable to the other in the case of damage to
one of the cables. The system shall allow
the user to copy or “split” the input sources
to several Output Modules using a fast
gigabit Ethernet switching hub.
