M-400
Discontinued

A breakthrough live mixing and recording system

The M-400 is a complete digital mixing system that provides the purest sound possible. The complete system incorporates a digital snake and mixing console in one integrated system.

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.

Support for LCR Sound Systems

The LCR (Left-Center-Right) mode is supported. Simply enable the LCR mode in the system configuration to activate this feature.

Support for Personal Mixing and Monitoring

The M-380 V-Mixer can be used to setup, configure and control multiple REAC-enabled M-48 Live Personal Mixers. The M-48 represents a breakthrough in professional personal monitoring and mixing.

Vintage Effects

Access some of Roland’s legendary vintage effects within the M-380. Original sounds used by engineers the world-over extends the range of live expression.

GEQs Can be Switched to PEQs

Any existing 31-band Graphic EQ can be switched to an 8-band Parametric EQ. The Real Time Analyzer enables a quick look and instant adjustment of the acoustic characteristics of a venue.

Vintage Effects

Roland has been a leader in creating some of the world's most popular effect processors. Included in the M-380 are six perfectly emulated popular and classic vintage effects.

Support 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.

* 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.
