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.
