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.
Convenient Connectivity
Our newly developed “REAC Embedded Power” 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.
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
IEMs 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.
■ Rear Panel
The M-48 is the “next generation” live personal mixer that offers

creates the ideal monitoring environment for live performance and
recording as well as studio applications.
