Lexicon RV-8 manual Amplifier Overview, Amplifier Channel Status

RV-8 Basic Operation

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.
