LX Power Amplifiers

Basic Operation

1. Power Switch

Disconnects power to the AC Input Connector. Set this switch to off when making or breaking connections to the amplifier, or when changing the setting of the MODE switch.

2. AC Input Connector

The AC input connector provides power to the unit with the supplied power cord (3 conductor, 14AWG). Do not use an extension cord. For optimal performance, use an isolated power receptacle with adequate current (15 or 20 amps). Line voltages ≥10% above the specified voltage may damage the amplifier. Line voltages ≤10% below the specified voltage may cause the amplifier to enter a protection mode, indicated by the red standby LED flashing.

3. INPUT 1 to 7 (LX-7) or 1 to 5 (LX-5)

Provide audio input for the speakers connected to the corresponding audio outputs. When using the unbalanced (RCA) audio inputs, make sure the UNBAL/BAL switch located to the left of each XLR connector is set to UNBAL. When using the balanced (XLR or 1/4-inch tip/ring/sleeve) audio inputs, make sure the UNBAL/BAL switch is set to BAL. The illustrations below show the appropriate cable ends for 1/4-inch T/R/S and XLR connectors.

4. OUTPUT 1 to 7 (LX-7) or 1 to 5 (LX-5)

Provide audio output for the speakers. 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 connections between the amplifier and the speakers. Observe correct speaker polarity.

WARNING Do not connect the OUTPUTs of one channel to the OUTPUTs of other channels or to other amplifiers.

Note:

If the rear panel MODE switch is set to INDIVIDUAL, speakers must have impedance ratings of 2Ω or higher. If set to (BRIDGED), speakers must have impedance ratings of 4Ω or higher. Using speakers with lower than recommended impedance ratings might activate protection modes.

5. MODE Switch

Configures channels 1 and 2 or 3 and 4 for INDIVIDUAL or (BRIDGED) operation. When set to INDIVIDUAL, all INPUTs and OUTPUTs function as separate channels. When set to (BRIDGED), the selected INPUTs and OUTPUTs are combined to create a single high-power channel.
