1. Power Connection and Fuse

Connect the power cord to this IEC socket securely,
and plug the other end into a live AC outlet. Make sure
the AC outlet has the correct voltage indicated next to
the IEC socket.
Disconnecting the plug's ground pin is
dangerous. Don't do it!
The fuse is located behind the fuse cover, at the
bottom of the IEC socket. See the "Troubleshooting"
section on page 9 for information about replacing the
fuse.

2. Power Switch

Press this switch left to turn the MRmk3 studio
monitor on. Make sure the level control [6] is down
before you turn it on. When the power switch is turned
on and the MRmk3 studio monitor is plugged into an
AC outlet, the Running Man logo on the front of the
monitor illuminates to let you know that it's ready to go.

CAUTION: REPLACE WITH THE SAME FUSE AND RATING.
DISCONNECT SUPPLY CORD BEFORE CHANGING FUSE.
Press the right side of this switch down to put the
speaker into standby mode. It will not function, but
the circuits are still live. To remove AC power, either
turn off the AC supply, or unplug the power cord from
the speaker and the AC supply.

3. Signal Inputs

Connect the line-level signal from the mixer
(or other signal source) to one of these input jacks.
There are three types of input connectors to choose
from: balanced XLR, balanced 1/4-inch, and unbalanced
RCA. Since all three of them are connected together
electrically, do not connect more than one signal at a
time to the input jacks.
A balanced signal provides better noise rejection
and is the preferred method, especially if using a cable
longer than 20 feet (6 meters).
They are wired as follows, according to standards
specified by the AES (Audio Engineering Society):
Balanced XLR
Hot (+)
Cold (–)
Shield (Ground)
Balanced XLR Connectors
Balanced 1/4" TRS
Hot (+)

Unbalanced RCA

For more information on these connectors, see
