Never before has a personal mixer given you this much control and flexibility over your monitor mix. Designed for the performing musician, the M-48 enables control of up to 40 audio sources that can be managed via 16 stereo groups - assignable and unique per musician. Adjust your mix using level, pan, 3-band EQ and solo. Enhance the playing experience using built-in reverb and an ambient mic. Expand your options with multiple headphones jacks, separate balanced outputs and auxiliary input.

2. Unprecedented Personalization
The M-48 enables control of up to 40 audio channels via 16 stereo groups. No longer do you have to share the same sources and in the same order as
everyone else. Each musician can choose what he or she wants to listen to - a truly personal mix.

3. Professional Sound Control and Quality
Sweeten your monitor mix to your exact preferences with volume, pan, 3-band EQ and built-in reverb per group ?all instantly adjustable by convenient
encoder knobs. A limiter is incorporated for protecting your ears from sudden and dangerous volume spikes. Based on REAC, the all-digital connection
results in a low noise floor, improved musicality and crystal clear sound.

4. Unparalleled Usability
The LED indicators on the control knobs enable instant adjustment and visual confirmation at a glance, even on a dark stage. The built-in ambient mic aids
in communicating with other musicians without have to remove your ear-buds or headphones as well as enabling a stage/room feel if desired. The AUX
Input allows a metronome or other device to be mixed into the primary sound.

5. Convenient Connectivity
Our newly developed“REAC Embedded Power”(via the S-4000D) transfers both power and 40 channels of audio to the M-48 via a single CAT5e cable
?dramatically simplifying wiring and stage layouts. Mini jack and 1/4 inch phone jack headphone outputs are provided. Balanced TRS line outputs support
wedge or other types of powered monitors. An independent stereo output mini jack enables recording with superb sound quality.

9. S-4000D - The REAC Splitter Equipped with Embedded Power
“REAC Embedded Power”is unique Roland technology that enables the transfer of not only the digital audio signal but also the power required by the
connected device - all via one CAT5e cable. The S-4000D Splitter and Power Distributor is equipped with 10 REAC ports including 8 ports of REAC Embedded
Power. The S-4000D can automatically detect and distinguish a product not supporting REAC Embedded Power. In this case, power is not provided allowing
the S-4000D to also function as a standard splitter when required. The S-4000D is required to use the M-48s.

17. 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.
