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.

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.
