The Perfect Digital Solution for Live Audio Transfer and Mixing

RSS by Roland is continuing to evolve digital audio and live audio mixing. The V-Mixing System is fully digital using Roland's REAC (Roland Ethernet Audio Communication) technology to transfer audio from the high quality mic pre-amps on stage to the mixing console. V-Mixing System is the next generation in live audio mixing technology.

- Superb Sound Quality
- Quick and Easy Installation and Setup
- Intuitive and Easy Operation
- Supports advanced integration applications

Superb Sound Quality

The V-Mixing system uses the REAC technology to convert the audio to digital
on stage using high quality 24-bit remote-controlled mic pre-amps. Because the
V-Mixing System is all digital, the integrity and sound quality of the audio signal
is maintained from the stage units to the M-400 V-Mixer and back to the outputs
for connection to amps and speakers.

Quick and Easy Installation and Setup

The V-Mixing System uses the REAC protocol between the stage units and
console using a simple Cat5e cable connection. The Cat5e connection is also
immune from the hums buzzes and crosstalk associated with analog snakes.
With no configuration required, simply plug the Cat5e cable from the stage
units to the REAC A & B port located on the rear of the M-400 V-Mixer and the
system is ready to go.

Intuitive and Easy Operation

The M-400 V-Mixer features 25 x 100mm motorized and touch sensitive faders,
a large bright 800 x 480 color screen, dedicated effect knobs for EQ, Pan, and
Gain, and fully recallable scene settings. Designed for all levels operator, the
intuitive interface is quick to navigate and easy to learn.

Supports advanced integration applications

Up to 40 channels of multi-track audio can be recorded by simply connecting
a Cat5e cable from the REAC Split port on the M-400 V-Mixer to a gigabit
network port on your PC running Cakwalk's SONAR. You can connect the
V-Mixing System to Edirol's video mixers for a completely integrated audio
and video performance solution.

*1: When a REAC Splitter S-4000-SP or a switching hub is used in-line with REAC cables, the network latency will increase by the amount of processing delay introduced by the splitting device itself.
The actual delay is dependant upon the specifications of the splitting device, though the maximum delay amount for a single splitting device should be about 200 microseconds.
