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
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
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.
expansion of Digital Snake System
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.
