S-4000 Digital Snake Owner’s Manual
Optional Redundant Power Supply
The S-4000S and S-4000H units each provide rear panel EXT. POWER DC INPUT jacks for connecting an
optional S-240P External Power Supply Unit. The S-240P provides backup power—and uninterrupted
audio—should a unit’s internal power supply fail. As with the redundant REAC connection, this
provides an important “safety net” in critical sound reinforcement situations.
To provide redundant power for the entire system, use a separate S-240P for each S-4000S/
S-4000H unit.
The System Components: A Closer Look
S-4000S 40 Channel I/O Modular Rack
The S-4000S is the stage connection interface for the S-4000 System. Its modular design supports 40
channels of audio input and output (I/O). As standard, it comes in a 32x8 configuration—32 audio
inputs and 8 audio outputs.
The “modular” aspect of the S-4000S is in its connectivity. The unit’s chassis provides 12 slots for
various RSS modules. The standard 32x8 configuration includes:
•
eight SI-AD4 Input Modules
—Each SI-AD4 contains four balanced audio inputs with variable gain
preamps, phantom power, and pad. Additionally, each input is equipped with a 24-bit/96 kHz
A/D converter.
•
two SO-DA4 Output Modules
—Each SO-DA4 contains four balanced line level audio outputs.
Additionally, each output is equipped with a 24-bit/96 kHz D/A converter.
•
one S-REAC2 Module
—This module provides two REAC connection ports—one for the main REAC
connection, the other for a redundant backup.
•
one S-BP Blank Panel
—This panel covers the final unused module slot. An optional RSS module
can be installed here.
RSS modules are not user-installable. They must be installed at the factory or by an RSS
Authorized Service Center.
About the Remote Controlled Preamps
Each input on the SI-AD4 modules employ a newly-developed XR-1 variable gain preamp. Designed
for warm and accurate sound reproduction, the XR-1 accepts input signal levels from -65 to +10 dBu.
Additionally, it provides an enormous amount of headroom before distortion—an incr28 dBu
maximum input level. Each preamp’s gain is controlled remotely from the S-4000R or S-4000 RCS,
allowing you to optimize signal levels right at the connection interface.
If you’re connecting the S-4000 System to an analog mixing console, you may be wondering why you
need adjustable gain at the S-4000S’s inputs. After all, you have gain adjustment at the console inputs,
right? Well, there are a few very good reasons to adjust the signal level at the S-4000S inputs:
