The Difference Between Modes
Stereo Mode
Stereo mode is the typical way of using the amplifier. 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 14), a schematic
illustration in (Figure 15).
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 16). 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 17).
In Parallel mode, you can patch the input signal on to additional amplifiers by using any of the remaining input jacks. See Ch. 2 in (Figure 16).
Example:
• One mono signal driving both channels, with independent attenuation control for each speaker system.
