These are RCA phono jacks for inputting analog audio signals from
line level equipment. By default they are patched to CH47 and
CH48.

This turns the power on/off.
If you need to turn off the power completely, first turn off the
POWER switch, then unplug the power cord from the power
outlet. Refer to
Power Supply
Use this to connect the M-400 to an electrical ground.
Do not ground the M-400 to locations such as the following.
•
Water pipe (doing so may cause electrical shock)
•
Gas pipes (doing so may cause fire or explosion)
•
Telephone ground or lightning rod (hazardous if lightning
occurs)
Depending on the circumstances of a particular setup, you may
experience a discomforting sensation, or perceive that the
surface feels gritty to the touch when you touch this device,
microphones connected to it, or the metal portions of other
objects, such as guitars. This is due to an infinitesimal electrical
charge, which is absolutely harmless. However, if you are
concerned about this, connect the ground terminal (see figure)
with an external ground. When the unit is grounded, a slight
hum may occur, depending on the particulars of your
installation. If you are unsure of the connection method, contact
the nearest Roland Service Center, or an authorized Roland
distributor, as listed on the “Information” page.

Connect the included power cord to the AC INPUT connector.
Use the power cord clamp to prevent the power cord from being
accidentally disconnected.
For details on attaching the power cord clamp, refer to
“Attaching the power cord clamp” (p. 16).
Do not connect any power cord to the M-400 other than the
included one.
You can use this power cord hook to prevent the power cord from
being accidentally disconnected. This provides greater security than
the power cord clamp.
For details on attaching the power cord hook, refer to
“Attaching the power cord hook” (p. 16).
This cooling vent cools the M-400. When placing the M-400, take care
not to block the cooling vent.
You can use this with a padlock to secure the M-400 from theft.
fig.BatterySlotGuide.eps
This slot contains a lithium battery that maintains the M-400’s clock
function and preserves the mixer settings.
If the battery runs down, you’ll need to replace it. For details on
replacing the battery, refer to “About the internal lithium battery”
(p. 18).
