FEATURES & SETUP- REAR PANEL SWITCHES: INPUT CONFIGURATION

INPUT CONFIGURATION- This switch selects between STEREO or PARALLEL input configuration. The indicator LED’s above the switch confirm the switch setting.

STEREO: Each input is sent to its respective channel. Each channel has independent subaudio filtering, clip limiting, gain control, and outputs. In STEREO mode, a full-frequency signal may be presented to each channel.

When to use STEREO input configuration: Use STEREO for stereo sources (L-R inputs) and any other situation that requires each channel to be completely separate from the other.

PARALLEL: The CH 1 and CH 2 inputs are connected together, applying a single input signal to both channels of the amplifier. A signal into any input jack will drive both channels. Each channel's subaudio filtering, clip limiting, and gain control still function independently. Each channel feeds its own speaker load.

You can patch the input signal on to additional amplifiers (“daisy-chain”) by using any of the remaining input jacks. This feature eliminates the need for “Y” cables.

The orange PARALLEL LED on the front panel clearly indicates when the amplifier in configured for PARALLEL input.

When to use PARALLEL input configuration: Use PARALLEL when you need one signal to drive both channels.

NOTE: Ensure that the INPUT CONFIGURATION switch is set to STEREO when feeding two separate signals to the two channels.

NOTE: The “normal” position of the MODE switch is 2 CH when operating in STEREO or PARALLEL input for the operating conditions shown above. See the following section for more information regarding the MODE switch.
