M-48 Control
About the M-48
The M-48 is a next-generation live personal mixer that gives each
performing artist full individual control of the balance of the
personal monitor mix.
The M-48 operates as a REAC SPLIT device.

Where M-48 Settings Are Saved
M-48 settings are saved in each respective M-48 unit. The M-5000
imports the settings from each M-48 for editing and management.
The following two methods are available for saving M-48 settings
externally.

Connecting the M-5000 and M-48 Units
You connect M-48 units to the REAC A, B, and SPLIT/BACKUP ports
on the M-5000. Making settings and controlling the M-48 from the
M-5000 is not possible if the M-48 is connected via an XI-REAC card.
Connecting the M-5000 and an M-48 requires an optionally
available S-4000D splitter and power distributor.
Output from the M-5000’s REAC ports is split by the S-4000D to up
to 64 M-48 units connected using REAC cables.
The mixing engineer can make settings on each M-48 unit from the
M-5000.
Restrictions in Use with the M-48 at 96kHz
When the sampling rate is set at 96 kHz, the number of audio
channels that a REAC slave device present at the REAC port where
the M-48 is connected can send to the M-5000 is 32. Sending 33 or
more channels produces noise.
(Because of the M-48’s control signals, obtaining a band on
100BASE-TX ample enough for the REAC slave device to send 40
audio channels at 96 kHz is not possible.)
