Macro-Tech 24x6 & 36x12 Power Amplifiers
3.3 Wiring
This section describes the most common way to install
the Macro-Tech 24x6 and 36x12 . Each model is de-
signed for biamplified systems and includes both a
high-power and a medium-power channel. The input
and output terminals are located on the back 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 am-
plifier use and/or deliberate overpowering.
CAUTION: It is always wise to remove power from
the unit and turn the input level controls off while
making or changing connections—especially if the
load is a loudspeaker system. This will eliminate any
chance of loud blasts or damage to the loudspeakers.
Because each channel produces a different power
level, the Macro-Tech 24x6 and 36x12 are dedicated
Fig. 3.4 Wiring (a Macro-Tech 36x12 is shown)
to two-channel operation. They do NOT offer mono
operation.
WARNING: Never strap the outputs together for
Parallel-Mono operation! Never bridge the outputs
for Bridge-Mono operation!
Installation of the Macro-Tech 24x6 and 36x12 is very
intuitive. The Channel 1 input feeds the Channel 1 out-
put and the Channel 2 input feeds the Channel 2 out-
put. Be sure to connect the output wiring as shown in
Figure 3.4. Five-way binding posts are provided to fa-
cilitate easy connection of loudspeakers to each chan-
nel. Note: Because of its higher output power, Channel
1 of a Macro-Tech 36x12 has an additional set of bind-
ing posts. Observe correct loudspeaker polarity and
be very careful not to short the outputs of one channel
to the outputs of the other channel.

Use Channel 1 for loads like low-frequency drivers (like woofers) that need more power.
Use Channel 2 for loads like high-frequency drivers (like horns) that require less power.
