The Difference Between Modes
Stereo Mode
Stereo mode is the typical way of using the amplifi er. Each channel is fully independent. Separate signals connect at the inputs, the attenuation knobs
control their respective channels, and separate speakers connect to each output. The dip switches are set as shown in — Figure 16, a schematic
illustration in — Figure 17.
Examples:
• Two-channel (stereo) playback.
• Two independent mono signals, such as main and monitor mixes.
• Bi-amped operation, with the low frequencies in Channel 1 and the highs in Channel 2.

Parallel Input Mode
This mode is similar to the Stereo mode, except that the inputs for Channel 1 and Channel 2 are internally connected together. A signal into Channel
1 jack drives both channels directly (— Figure 18). Use Channel 1 Input, do not connect different sources to both channels. Each channel's attenuation
control still functions as usual, and each channel feeds its own speaker load. The dip switches are set as shown in — Figure 19.
In Parallel mode, you can patch the input signal on to additional amplifi ers by using any of the remaining input jacks. See Ch. 2 in — Figure 18.
Example:
One mono signal driving both channels, with independent attenuation control for each speaker system.
