3.6 Set Up and Wire Your System
First, turn down the Level controls (fully coun-
terclockwise) and turn off the amplifier.
3.6.1 Set the Mono Modes Switches
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.
3.6.2 Set Input Sensitivity
Set the Input Sensitivity switches of each chan-
nel to the desired setting (see Figure 3.7). Two
choices are available: 1.4V for full rated output
(33 dB gain), or a fixed voltage gain of 26 dB.
3.6.3 Stereo 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.
3.6.4 Bridge-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.
