3. Power Switch
Press this switch left to turn the MR10Smk3
studio subwoofer on. Make sure the level control [9]
is down before you turn it on. When the power switch
is turned on and the MR10Smk3 studio subwoofer is
plugged into an AC outlet, the LED [6] illuminates to
let you know that it’s ready to go.
Press the right side of this switch down to put the
subwoofer 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.

(or other signal source) to these input jacks.

This is where the signal is connected to the subwoofer
and adjustments are made to the frequency response of
the speakers to match the subwoofer’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 below
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. Voltage Selector Switch
Make sure the switch is in the correct position for
your local AC mains voltage before connecting the AC
power cord. Use a small flat screwdriver to slide the
switch, if required.
