Power
Voltage Selector
Before connecting the speaker to a power sup-
ply, ensure the voltage selector setting matches
your local main voltage supply (100
–
115V or
230V), +10% or –15%.
Fuse
The fuse protects your speakers and other com-
ponents of the RMS speakers from being dam-
aged by electrical under or over-powering,
spikes, and other anomalies. Do not use fuses of
any other rating except the ones indicated on
the back panel of the unit.
Fuses and Voltage
You must use different fuses for the 100
–
115V
and 230V setting. The 100
–
115V setting uses the
3.15A fuse, and the 230V setting uses the 1.6A
fuse. If you change the setting to 230V, you
must also change to a 1.6A fuse.
To change fuses:
1
Use a small screw driver to remove the fuse
holder.
2
Remove the factory-installed fuse.
3
Install the new fuse in the fuse holder so that
it goes in first.
Power Switch and AC Connector
The AC port accepts an AC power cord included
with your monitor. Once connected, use the
Power switch to turn the unit on or off. To com-
pletely isolate the mains, remove the power
cord.
Inputs
Analog
The analog audio input is a female XLR connec-
tor. The input is electronically balanced with
the following connections.
If the source signal is unbalanced, connect the
unused pin to ground. For optimum results, use
only quality cable and connectors.
Voltage selector
Always make sure to install the proper fuse
after changing voltage settings. See below.
