3.3 Wiring

The following instructions describe the most common
ways to install your amplifier in a sound system. The
input and output terminals are located on the back
panel. Please use care when making connections, se-
lecting signal sources and controlling the output level.
The load you save may be your own! Crown assumes
no liability for personal injury or damaged loads from
careless amplifier use or deliberate overpowering. All
units include an output cover to prevent accidental elec-
trical shock and short circuits. We strongly recommend
that you use this safety feature.
DANGER: The outputs can produce lethal energy
levels. Do not change the output wiring unless the
amplifier has been off for at least 10 seconds. Turn-
ing off the amplifier also reduces the chance of blasts
that can damage your hearing or loudspeakers.
Your amplifier can be operated in Stereo, Bridge-Mono,
or Parallel-Mono mode by switching the back panel ste-

reo/mono switch. Turn off the amplifier and wait at
least 10 seconds before changing this switch or in-
ternal damage to the circuitry may result. There are
VERY IMPORTANT wiring differences among the three
operating modes that will be discussed next.

3.3.1 Stereo (Two-Channel) Operation

In Stereo mode, installation is intuitive: input Channel 1
feeds output Channel 1, and input Channel 2 feeds out-
put Channel 2. To activate Stereo mode, first turn off the
amplifier and wait 10 seconds for the power supply to
discharge. Then, slide the stereo/mono switch to the
center position, and connect the output wiring as shown
in Figure 3.4.
CAUTION: In Stereo mode, never parallel the two
outputs by directly tying them together, and never
parallel them with the output of another amplifier.
Such a connection does not result in increased power
output, but may result in overheating and premature ac-
tivation of the protection circuitry.
