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.

Page 2 THE SLAVE Every 40-channel S-4000 system has one and only one SLAVE device. The Cat5e cable for the SLAVE device comes directly from the MASTER unit or from a gigabit switch connected to the MASTER unit. The outputs of this device come from the MASTER unit. The inputs to this device are sent back to the MASTER unit and only to the MASTER unit.

Returns from FOH position go back to the stage.
Page 4 MULTI-UNIT S-4000 SYSTEMS Each S-4000 system’s Cat5e cable can transport up to 40 channels of high quality 24-bit 96kHz audio The typical configuration for a basic system is 32x8 and consists of an S-4000S-3208 and an S- 4000H connected using one Cat5e cable, or (two when using redundant cables.) For a 64x16 system, two separate 32x8 systems are specified using two independent Cat5e cables.
