3.3 Wiring
The following section describes common ways to in-
stall your amplifier in a sound system. The input and
output terminals are located on the rear panel. Please
use care when making connections, selecting signal
sources and controlling the output level. The load you
save may be your own! Crown assumes no liability for
damaged loads resulting from careless amplifier use
or deliberate overpowering.
CAUTION: Always remove power from the unit and
turn the level controls off when making or breaking
connections—especially if the load is a loudspeaker
system. This reduces the chance of loud blasts or dam-
aged loudspeakers.
Macro-Tech amplifiers may be operated in one of three
modes (Stereo, Bridge-Mono, and Parallel-Mono) by
switching the Stereo/Mono switch on the rear panel.
There are VERY IMPORTANT wiring differences be-
tween these three modes which are discussed next.
3.3.1 Stereo (Two-Channel) Operation
The installation is very intuitive in Stereo mode. The in-
put of Channel 1 feeds the output of the same channel
as does the input of Channel 2. To put the amplifier into
Stereo mode, first turn the amplifier off, then slide the
Stereo/Mono switch to the center position, and prop-
erly connect the output wiring as shown in Figure 3.4.
Two sets of binding posts are provided for each chan-
nel to facilitate easy connection of multiple speakers to
each channel. Observe correct loudspeaker polarity
and be very careful not to short the outputs of one
channel to that of the other channel while in Stereo
mode.
CAUTION: In Stereo mode, never parallel the two
outputs by directly tying them together or parallel-
ing them with the output of any other amplifier.
Such connection does not result in increased power
output and can cause premature activation of the pro-
tection circuitry to prevent overheating.
