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. It provides the highest level of sound monitoring quality for both headphones and IEMs (In-Ear Monitors) as well as for wedge and powered monitors. The superb sound quality creates the ideal monitoring environment for live performance and recording as well as studio applications.

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.


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.

Unparalleled Usability

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.

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.
