RV-8 Basic Operation
2-13
AMPLIFIER OVERVIEW
The RV-8 features a 7-channel power amplifier with 140W per
channel. The RV-8 can be configured so that all amplifier channels
are dedicated to the Main Zone or so that outputs 3 and 7 (labeled
Rear Right and Rear Left) are used for Zone 2 or Zone 3. Heavy duty
gold plated 5-way binding posts are provided for speaker
connections.
The amplifiers feature advanced thermal current and DC protection
for each channel. Thermal protection monitors the temperature of
the chassis and heatsinks and automatically deactivates the specific
channel(s) when they exceed their normal safe operating temper-
ature. Current protection ensures that the output transistors are
protected by limiting the current capability which is determined by
the output voltage, while DC protection prevents DC and
frequencies below 10Hz from reaching the speakers. Dedicated
channel status LEDs are located on the front panel to provide at-a-
glance viewing of channel status at all times. If the main power
transformer temperature exceeds 100°C, the transformer will
deactivate, all channel status LEDs will no longer be lit and the red
standby LED will flash rapidly. Once the transformer has cooled, it
automatically resets and the amplifier operates normally; the
channel status LEDs turn back on, and the red standby LED is no
longer lit.
The amplifiers are designed to meet the highest standards of perfor-
mance and sound quality. In addition, THX Ultra2 certification
ensures that the amplifiers meet the highest standards set forth by
Lucasfilm's Home THX division.
AMPLIFIER CHANNEL STATUS
Each channel has a blue Channel Status LED on the front panel that
is illuminated when the unit is powered on. If there is a problem
with an amplifier channel, the LED will turn off.
MAKING CONNECTIONS WITH THE AMPLIFIER
OUTPUT
The amplifier output connectors can accept bare speaker wires,
banana plug connectors or certain spade connectors. When using
bare speaker wires, loosen the connector, insert the wire into the
top of the receptacle, then tighten the connector. The same
procedure should be used for spade connectors. Banana plugs
should be inserted into the outward-facing receptacle.
Use heavy-gauge speaker cable to ensure low-impedance connec-
tions between the amplifier and the speakers. Observe correct
speaker polarity.
CAUTION! Do not connect the outputs of one channel to
the outputs of other channels or to other amplifiers.
