S-4000S MASTER / SLAVE / SPLIT QUICKSTART
The S-4000 Modular Digital Snake delivers 24-bit, 96kHz audio over Cat5e cable using Roland’s
REAC protocol. This document outlines how to set the REAC Modes for all of the S-4000 units
used to configure an S-4000 digital snake.
There are currently two products, the S-4000S and the S-4000H, used to configure an S-4000
digital snake. Typically the S-4000S is on stage and provides connections for all source inputs as
well as returns for speakers and monitors. S-4000H units are used at the FOH position and at all
split locations.
Each S-4000S product has a small “dip switch” that is used to select the REAC MODE
for that device.
THE MASTER
Every 40-channel S-4000 system has one and only one device that is configured as the system
MASTER.
The inputs to this device are sent to every other device in the system.
Typically the MASTER device is the S-4000S unit that is on stage.
