The M-300 V-Mixer provides powerful mixing capabilities with 32 mixing channels, 8 aux buses, and 4 matrices in a compact size. It integrates seamlessly with other Roland devices using REAC technology over Ethernet. The mixer has 4-band parametric EQ and dynamics processing on each channel as well as effects processors. It allows flexible system configurations and remote control capabilities. The M-300 is well-equipped for sound reinforcement and live production applications where space is limited.

2. Compact, uncompromising sound and features with impressive mixing capacity
The M-300 V-Mixer is the ultimate solution for a variety of venues and applications. It provides a substantial mixing capacity of 32 mixing channels, 8 aux buses,
and 4 matrices. The M-300 V-Mixer seamlessly integrates with other REAC devices. The user can directly operate the Digital Snake preamp, control an M-48
Personal Mixer, and set up the I/O for the S-4000M REAC Merge Unit. All of these features are contained in a very compact size and at a weight of 9.8kg (21 lbs
10 oz). The M-300 is the perfect choice for any venue with a limited set-up area, as well as for mobile sound reinforcement. Optional rack rails are also available.

3. Powerful Built-in Channel Effects
Equalization of channels and dynamics are the foundation of any great mix. The enhanced sound shaping abilities of the M-300 input channels include
4-band fully parametric EQ as well as gate and compression. A Key-In filter can be used for the Gate/Compressor to enable more expressive mixing. The 4
multi-effects processors can be set to use any of 11 different effects types. In addition to Reverb and Delay, modulation effects such as Chorus and Phaser
are also available. The M-300’s busses are also equipped with 8 bands of fully Parametric EQ and Signal Delay on each Aux, Matrix and Main output. The
M-300 is fully equipped with all of the sound adjustment tools built-in and ready to go.

5. USB memory recorder/player
Record the output of the M-300 Main, assigned AUX bus or MATRIX bus directly to a USB memory drive connected to the built-in USB port. A mix produced
with the M-300 can be saved as an uncompressed WAV file, without the need for an external recorder. WAV files on the USB memory drive can also be
played back on the M-300 and used for background music/tracks. User settings and mixer data can also be saved to a USB memory drive.

6. Advanced control surface design
The M-380 and M-400 V-Mixers are highly regarded for their ease of use and the M-300 continues this tradition starting with 17 - 100mm motorized
faders. Central to the M-300’s operation is a high-resolution 800x480 pixel color display. Channel Parameters such as Gain, Pan, EQ and Dynamics can be
comfortably operated from the Channel Edit section located on the left side of the display. All parameters can be instantly saved and recalled from Scene
Memory. The layers of faders can be easily switched with the LAYER button. Faders can be accessed and arranged freely, and saved as a User Layer.

7. Control remotely using a wireless LAN
By enabling Remote Desktop Connection on a local PC directly connected to the M-300 via the USB, the M-300 can be controlled remotely from another
PC using a wireless LAN. An iPad or tablet PC can be used to control the M-300 from a remote location. For example, you can be seated in the audience to
adjust the house mix during the rehearsal, or stand onstage to adjust the monitor mix while consulting the stage performer. The M-300 enables new mixing
possibilities that you could never achieve with an analog console.

8. Control remotely from a PC
The M-300 can be controlled remotely in real-time from a PC (Windows) connected via the USB port. Mixing functions on the M-300 can be operated
directly from a PC by using the M-300RCS dedicated control software which has the same GUI as the M-300 color display. The M-300RCS can also be
operated in offline mode, allowing data for various settings to be created in advance and saved to a USB memory drive. When you get to the venue, load
the settings and jump right into sound check and rehearsal.

9. Multi-channel recording to a DAW
Forty channels of 24-bit audio can be recorded directly to a PC (Windows) by connecting a REAC port to the gigabit Ethernet port on the PC via a single
Cat5e cable. Audio is recorded as individual WAV files using Cakewalk SONAR and can be mixed after recording using the powerful digital audio tools and
effects in SONAR.

10. V-LINK - Audio and Visual Solution
By connecting the MIDI input/output to the video switcher such as the V-1600HD, V-LINK automatically synchronizes the audio of the M-300 with the visual
images allowing“audio follows video”.

11. Support and management of multiple M-48 Live Personal MixersSupport and management of multiple M-48 Live Personal Mixers
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-5000, M-480, or M-200i Live Mixing Console allowing
the FOH engineer to assist in setup and mixing.

18. 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.
