(33 dB gain), or a fixed voltage gain of 26 dB.

 

To run in Stereo Mode: On the back panel, set the Bridge Output switch and the “Y” Input switch OFF (Figure 3.6).

If you want to give up stereo capabilities in order to drive your speakers louder, set the Bridge Out- put switch to ON. Then a single input will feed a single output with twice the voltage of stereo mode. You might use this configuration if you are running a distributed sound system from the K Series amp.

If you want to feed a mono audio signal to two channels, each with its own level control, set the “Y” Input switch ON. This connects both inputs in parallel. You might use this setup if you’re running a monitor speaker on one channel and a main speakers stack on the other channel, and you want to feed them the same signal.

If you want daisy-chained inputs fed to a double- voltage output, set the Bridge Output switch ON and the “Y” Input switch ON. For example, con- nect the input signal to the CH-1 XLR connector and use the CH-2 XLR connector plus the two 1/4-inch phone jacks for daisy-chained outputs that feed other power amplifiers.

3.6.3Stereo Mode See Figure 3.8.

INPUTS: Connect input wiring to both channels.

OUTPUTS: Maintain proper polarity (+/–) on output connectors.

Connect Channel 1 positive (+) speaker load to Channel 1 positive terminal of amp; repeat for negative (–). Repeat Channel 2 wiring as for Channel 1.

3.6.4Bridge-Mono Mode See Figure 3.9.

Use this configuration if you want to give up stereo capabilities in order to drive your speak- ers louder.

On the back panel, set the Bridge Output switch ON.

INPUTS: Connect input wiring to Channel 1 only.

OUTPUTS: Connect the speaker across the posi- tive terminals of each channel. Do not use the negative terminals (black binding posts) when the amp is being operated in Bridge-Mono mode.

NOTE: The Channel 2 level control should be set fully counter-clockwise when oper- ating the amplifier in Bridge-Mono mode.
