More Info

Easy to Use
The M-400 is designed to be fast and intuitive to use for the beginner or the experienced professional. It features dedicated knobs and buttons for all console functions, 25 touch-sensitive moving faders, onboard Help, large - bright TFT LCD display and Cat5e connectivity for low cost installation and truly portable systems.

Outstanding Sound Quality
The M-400 is a complete digital solution maintaining 24-bit audio from the stage to the splits and back to the stage. Preamps on stage provide the highest possible sound quality and intelligibility. Cat5e snake eliminates the high frequency losses inherent in analog snakes. Onboard digital processing, channel DSP and routing eliminate any chance for buzzes from extra cabling and analog to digital conversion losses. Built-in 24-bit recording provides lossless capture of live events. The Digital Split allows lossless transmission to monitoring, recording or broadcast positions. Bus and Main LRC returns over Cat5e enables a complete digital signal path back to the stage.

Powerful Digital Benefits
Instantly change from event to event with 300 Scenes for total recall of all mixer, effect and routing parameters. Password level access provides only the relevant controls for any particular type of user. PC software allows loading/saving setups as well as real-time control. Libraries provide the ability to for storing custom channel, patchbay and effect settings. Direct to PC recording over Cat5e enables up to 40 channels of direct digital recording.

m48_standSupport and management of multiple M-48 Live Personal Mixers for the ultimate in monitoring environments
For the performing musician wanting the best possible sound quality and flexibility in their individual stage mix, the M-48 Live Personal Mixer offers control over 40 audio sources that can be easily managed in 16 assignable stereo groups. Configurations are straightforward with the ability to control, save and recall all connected M-48s from an M-400 or M-380 V-Mixer allowing the FOH engineer to assist in setup and mixing. The use of IEMs (In-Ear Monitors) dramatically reduces the amount of sound picked up by stage microphones. It also eliminates feedback while providing superb sound quality for both live performance and recording.

logo_reacThe backbone of the V-Mixing System is based on REAC – Roland’s Ethernet Audio Communication transmission protocol for low latency, high quality digital audio transfer. Products using REAC technology are installed today in many venues and have been used for high profile events worldwide. REAC’s 24-bit, 40x40 channel protocol delivers pristine digital audio via lightweight, inexpensive and easy to install cable (Cat5e). REAC technology is immune to externally induced signal quality degradation or hums and buzzes typically found in analog systems. You have more freedom in cable placement resulting in lower cost and better sounding. Learn more about the power and benefits of REAC.

* 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 dependent upon the specifications of the splitting device, (0dBu=0.775Vrms) though the maximum delay amount for a single splitting device should be about 200 microseconds.
In the interest of product improvement, the specifications and/or appearance of this unit are subject to change without prior notice.
