and adjustments are made to the frequency response of
the speakers to match the monitor's location and the
room's environment.

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 10 for information about replacing the
fuse.

2. Power Switch

Press this switch left to turn the MR studio
monitor on. Make sure the level control is down
before you turn it on. When the power switch is
turned on and the MR studio monitor is plugged into
an AC outlet, the LED on the front panel illuminates
green to let you know that it's ready to go.
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/unbalanced 1/4" 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
