The S-4000S is a modular digital snake system delivering up to 160 channels
of high quality 24-bit/96kHz audio over Cat5e cables. System highlights
include remote controllable XR-1 professional quality mic preamps, redundant
ethernet ports and splits using standard Ethernet hardware.
Join the Revolution
from Analog to Digital Snakes
Make the change from analog multi-pair cable,
which is thick, heavy, difficult to install
and prone to interference and audio degradation;
to the next generation: a Digital Snake. Digital
Technology offers lightweight, easy to install,
and superb quality audio. This is the new
generation of audio transmission made possible
using Roland's original "REAC" Ethernet
audio technology and the S-4000 Digital Snake.
Standard setup of Digital
Snake
Improve your audio with
the superior clarity and intelligibility of
an S-4000 system
Audio from a microphone is very low-level
audio. When you run low-level signals down
an analog snake you have inevitable losses
from the resistance, capacitance and inductance
of the audio cable. In addition, analog cables
are susceptible to induced hums and buzzes
from transformers, power lines and other environmental
"hazards".
By placing your mic preamps right next to
your sources, and converting your audio to
digital right on the stage, you avoid all
of these audio hazards and your sound quality,
clarity and intelligibility are all greatly
improved.
Simple and flexible installation/operation
The S-4000 is very easy to configure and use.
Using standard 32 input and 8 output or return
systems, it's easy to configure 32x8, 64x16
and 96x24 systems. To make the system work,
you just plug in the cabling and turn on the
power. No computer knowledge is needed!
The gain of the preamps is easily controlled
using the S-4000R Remote Controller from either
the stage or FOH console location. You can
also use a computer to control up to 160-channel
systems using the free S-4000RCS software.
Very low cost and flexible
installation using Cat5e Ethernet cable
Ethernet cabling is very low cost as well
as very slim and lightweight. That makes installation
much easier than using analog cable bundles.
Also, due to digital audio's immunity to environmental
hums and buzzes, you often have many more
routing options for running cable. Splitting
your audio is very easy with the S-4000 system.
Using standard Ethernet switching hub, you
can split all of your stage source audio to
a recording, broadcast or monitor location.
Cable runs can also be extended from the 100-meter
standard Ethernet spec using these same hubs.
Installation cost and time can be drastically
reduced compared with installations using
Analog multi-pair. And since Cat5e cable is
so inexpensive and easy to run, you can add
a few extra cables at the time of the installation,
so that later it will be very easy to add
extra input and output channels. Your customers
will thank you for designing a "future-proof"
system!
Cabling and Power Supply
Redundancy provides a secure audio transmission
system
The S-4000 is designed to be a trouble free
system, and is equipped with various mechanisms
for safety and redundancy. Heavy duty Neutrik
ｮ connectors are provided for the Main and
Backup cables on all chassis. Furthermore,
redundant Main + Backup cable connections
are standard, providing security and the automatic
continuation of audio transfer even in case
one of the cables is accidentally damaged.
The S-4000H provides heavy-duty strain relief
rails. All power switches and cables have
security covers to prevent accidentally unplugging
or turning off the power. Both the S-4000S
and S-4000H can use the optional S-240P redundant
backup power supply. In fact, system reliability
and redundancy has been at the heart of all
of the S-4000's design criteria.
Functional
expansion of Digital Snake System
Version 1.5
With an updated S-4000 system, ｔhe
built in pre-amp (XR-1) of an SI-AD4
can be remotely controlled from
select digital mixing consoles from
YAMAHA Corporation.
By connecting the REMOTE terminal of an S-4000S or S-4000H with the RS-422 HA REMOTE connector on select YAMAHA consoles using an RS-232C/RS-422 converter, the Gain/PAD/Phantom power of the SI-AD4 “4Ch Analog Input Module” built in to an S-4000S can be remotely controlled.
