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.

2. Part of The V-Mixing
System Total
Integrated Solution
REAC (Roland Ethernet Audio
Communication) technology is the
cornerstone of the V-Mixing System.
REAC is Roland’s original technology
for low latency, high quality digital
audio transfer. REAC is an Ethernet
based technology that enables multiple
components to be easily integrated
using lightweight Cat5e/6 cable. With
just a single inexpensive cable, 40
input x 40 output channels of 24-bit
uncompressed audio data (including
level and control information) are
transferred.
Digital Snakes
Enjoy superior clear sound, great intelligibility with
minimal latency and the freedom to split or extend
your audio sources anywhere.
Bridging
The S-MADI REAC Bridge enables connectivity
b e t w e e n M A D I - e q u i p p e d d i g i t a l a u d i o
mixers/systems to any REAC-based devices.
Personal Mixers
The M-48 is the “next generation”
live personal mixer that offers
musicians the flexibly to control
exactly what they want to listen to
during their performances.
REAC Driver
The REAC driver enables users to
capture up to 40 audio channels from
a Digital Snake or V-Mixing System
directly into most ASIO-based DAWs
via Cat5e/6 cable.
Recording
Multi-channel recording and playback,
including virtual rehearsal is accomplished
with reliability and stability using the dedicated
R-1000 48-Track Recorder/Player.

represents a premium console choice. More than a digital mixing console; it is the
heart of a V-Mixing System ideal for any live event applications in corporate, church,
education or rental/staging environments.

10. Create a 40x40 Digital Snake using VLAN
Using VLAN technology, a single Cat6 cable can be used to transfer 40 inputs and 40 outputs between two points using Roland Digital Snakes.
1. Using a gigabit smart switch, create a
VLAN for each REAC network/path.
2. Create an additional VLAN assigned to a
specific port that consists of tagged VLANs
defined in step 1.
3. Setup the second smart switch with the
same configuration.
Two separate REAC networks are running
but the smart switches have the ability to
amalgamate multiple REAC networks down
one physical CAT6 cable and separate
out again at the other end. Setting up
additional ports on the switch as“seeing”a
specific VLAN allows normal splits to occur.
