These are balanced XLR-3-31 female input jacks for inputting analog
audio signals from mics or line level equipment. Make connections
after first checking the wiring diagrams of other equipment you
intend to connect.

By default, the CONSOLE INPUT jacks are patched to CH33–
CH40.
When connection cables with resistors are used, the volume
level of equipment connected to the inputs (CONSOLE INPUT,
STEREO IN, TALKBACK MIC IN) may be low. If this happens,
use connection cables that do not contain resistors.

These are balanced XLR-3-32 male output jacks for outputting
analog audio signals.Make connections after first checking the
wiring diagrams of other equipment you intend to connect.

By default, AUX1 OUT–AUX6 OUT and MONITOR L/R are
patched to the CONSOLE OUT jacks.

REAC A, B ports
These are RJ45 connectors for connecting input/output units
such as the S-1608, S-0816, or S-4000S via Cat5e Ethernet cables.
These connectors support Cat5e Ethernet cables up to 100
meters long. If you need a longer connection, we recommend
that you use the optional S-OPT.
The default input/output patching between the M-400 and
input/output units connected to REAC ports A and B is as
follows.
•
SPLIT/BACKUP port
This is used as a backup connection for the REAC A port, or for
split connection. You can also use it for multitrack recording on
a PC in which you’ve installed the REAC driver.
For details on backup connections and split connections, refer to
“REAC applications” (p. 181).
The REAC A and B ports and the SPLIT/BACKUP port have
REAC indicators that show the REAC communication status.
The state of the REAC indicator has the following significance.
1. CONSOLE INPUT jacks
2. CONSOLE OUTPUT jacks

The CONSOLE INPUT jacks and CONSOLE OUTPUT jacks can
also be used as input/output jacks for inserting external effect
processors into channels. For details, refer to “Inserting an
external effects device” (p. 137).
