Operating Voltage
The Omega Mono power amplifier is set at the factory (internally) for
100V, 120V, 230V, or 240V AC mains operation, as appropriate for the
country in which it is to be sold. (
230V only in European Union countries,
in compliance with CE regulations.
) The voltage setting may not be
changed by the user.
Make sure that the label on the rear panel indicates the correct AC op-
erating voltage for your location. Attempting to operate your power am-
plifier at an incorrect voltage may damage the unit.
Warning:
The voltage setting of the Omega Mono power amplifier
may not be changed by the user and there are no user-
serviceable parts within the unit. Please refer any
problems to an authorized Classé service center.
If the AC mains voltage indicated on your power amplifier is incorrect,
please contact your authorized Classé dealer or distributor.
The Omega Mono power amplifier can be powered by a normal 15-
ampere AC mains line. For peak performance, we suggest that you con-
sider dedicating an outlet exclusively for the Omega Mono.
The Omega Mono power amplifier includes protection circuitry that
will prevent the amplifier from operating at dangerously high or low
voltages.
•
at startup:
the AC mains voltage must be within a range
of approximately -15% to +10% of its nominal value at
startup, or the amplifier will not turn on. For example, a
120V unit requires the AC mains to be between approxi-
mately 95V–135V in order to turn on.
•
over-voltage during operation:
if the AC mains voltage
surges by roughly 10% or more during operation, the am-
plifier will enter protection mode and shut down. The
Ω
Ω

indicator
color will alternate between red and blue to in-
dicate that the protection mode has been engaged.
•
under-voltage during operation:
if the AC mains volt-
age sags by 15% or more, the amplifier will continue to op-
erate (since this does not present a particular danger to the
amplifier), but note that it will not be able to achieve its
usual standard of performance under these compromised
conditions. The
Ω

indicator
will alternate between red
and blue to indicate this condition.
