Parallel Input Mode

What it is

The Parallel Input switches let you operate the amplifier in Parallel mode, delivering the same signal to both channels without using a Y cable. Each channel drives its own speaker load, with independent gain, filtering, and clip limiting.

Set switch positions 4 and 5 to "PARALLEL INPUTS" to couple the inputs together (Figure 8). Turn the switches to "STEREO" for stereo, bi-amping, or other 2-channel modes.

With the inputs in parallel, you can use the other set of input connectors to carry the signal to other amps (Figure 9). This is often called a “daisy-chain.”

When to use it

Use the Parallel mode when driving two speakers with one input signal (Parallel mode) while keeping separate control of both channels' gain, filtering, and limiting. Use Parallel mode and Bridge Mono mode to patch the signal to additional amplifiers through the extra input jacks.

Note: If you're using a balanced signal, use only balanced patch cables; even one unbalanced cable will unbalance the entire signal chain, possibly causing hum.

Note: Turn off the “Parallel Inputs” switches when feeding the amp two separate signals.
