G
WORD CLOCK IN/OUT connectors
These are BNC connectors used to transmit/receive word
clock signals to/from an external device. The WORD
CLOCK IN connector is internally terminated by 75
ohms.
H
MIDI IN/OUT connectors
These connectors are used to transmit and receive MIDI
messages to and from external MIDI devices. The MIDI
IN connector receives messages from an external device,
and the MIDI OUT connector transmits messages from
the M7CL. These are used mainly to record M7CL param-
eter operations or scene/library selections on an external
device, or to control M7CL parameters from an external
device.
I
ETHERNET connector
This connector allows the M7CL to be connected via a
CAT3 (transmission speed up to 10 Mbps) or CAT5
(transmission speed up to 100 Mbps) Ethernet cable to a
Windows computer. This is used mainly to control mix
parameters or edit scene memories and libraries from the
dedicated "M7CL Editor" application program.
NOTE
• The DME Network Driver required for connection to the Ethernet
connector, the Studio Manager required for starting up M7CL Edi-
tor, and the M7CL Editor itself can be downloaded from the follow-
ing Yamaha website.

Slots 1–3
These slots allow separately sold mini-YGDAI I/O cards
to be installed to expand the input/output ports.
K
AC IN connector
Connect the included power cable to this connector.
L
POWER switch
This switch turns the internal power supply on/off.
M
DC POWER INPUT connector
You can connect the separately sold PW800W power sup-
ply here as a backup external power supply. If the
PW800W is connected, the M7CL will continue receiving
power from the PW800W even if its own internal power
supply shuts down due to a problem.
CAUTION
• If you connect the PW800W, you must be sure to first power-
off both the M7CL and the PW800W. Then use the optional
power supply cable (PSL360) to make the connection. Failure
to observe this will cause malfunctions or electric shock.
HINT
• If the PW800W is connected, the M7CL will operate correctly
whether its own internal power supply and the PW800W are both
turned on, or whether just one of these is turned on.
• If both power supplies are on, and an abnormality is detected in
one of the power supplies, the M7CL will automatically switch to
the other power supply. If this occurs, the touch screen will show a
message to indicate this.
N
Grounding screw
In order to ensure safe operation, use this screw to connect
the M7CL to an electrical ground. Making a correct
ground connection will effectively eliminate noise such as
hum and interference.
