Operation
This section describes the operation of the Omicron Monaural Power
Amplifier.
Turning on AC power
The Omicron Monaural Power Amplifier is turned on by means of a
power switch located on the left side of the unit. Do not turn the AC
power on until all connections have been made. When AC power is
applied, the Omega symbol on the front of your Omicron Monaural
Power Amplifier will FLASH in blue for 10 seconds, which indicates a
normal initialization. When the Omega symbol switches to a solid
blue indicator your Omicron Monaural Power Amplifier is in the
normal operational mode.
Protection mode
The protection circuitry in the Omicron Monaural Power Amplifier
was originally designed for the Omega Mono Power amplifier. This
unique design utilizes current sensors for all internal power supplies.
This new arrangement removes fuses from the Mosfet pre-driver
stage and the result is a new level of uncompromised sonic
performance. The Omicron Monaural Power Amplifier also has a
protection circuit designed to detect unusual distortion and DC
content at the amplifiers output.
