Reference Two
Channel Power
Amplifier
The Reference Two Channel Power Amplifier is
supplied with the following accessories:
• Power cord.
• Bridge-mode link.
• This manual.
If any of these items are missing please contact your
retailer.
NOTE: You should retain the packaging in case you
need to transport the unit.
Siting
During normal operation the internal heatsinks may
become quite hot. The power amplifier should therefore
be positioned to allow a free flow of air through the
cooling vents on each side of the case. Do not place
the power amplifier:
• In direct sunlight.
• Near heat sources, such as a radiator.
• Stacked with any other audio products, as the heat it
generates may damage the other products.
• On a soft surface, such as a carpet, which would
obstruct the ventilation holes in the base.
Standby
Once set up, the power amplifier can be left in standby
as it consumes minimal power in this mode.
If you are not going to use the power amplifier for a
period of several days you should switch off the unit
completely, at the back panel and disconnect it from
the AC power supply.
Trigger input
The Trigger input can be used to bring the power
amplifier out of standby by applying a signal from a
control unit or preamplifier.
Operation
The indicator on the front panel shows the status of the
amplifier:
