AMPLIFIER OVERVIEW
Understanding the Amplifier
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 connec-
tions.
The amplifiers feature advanced thermal, current, and DC protec-
tion for each channel. Thermal protection monitors the tempera-
ture of the chassis and heatsinks and automatically deactivates the
specific channel(s) when they exceed their normal safe operating
temperature. Current protection ensures that the output transistors
are protected by limiting the current capability which is deter-
mined 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 trans-
former 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 will automatically be reset and the amplifier will oper-
ate normally. The channel status LEDs will turn back on, and the
red standby LED will no longer be lit.
The amplifiers are designed to meet the highest standards of
performance and sound quality. In addition, THX Ultra2 certifica-
tion ensures that the amplifiers meet the highest standards set forth
by Lucasfilm's Home THX division.

• Selecting LISTEN TO PRESET will load the preset frequency.
• Select the NAME parameter to customize the preset name.
The preset name can be up to eight characters long.
• Select CLEAR PRESET to clear the frequency and band
information from the preset.
See page 5-2 for additional tuner edit preset information.
