INSTALLING AN RM MODULE

STEP 3: Plugging-in the RM MODULE

A. Turn-off amplifier. Remove amplifier cover and

locate the two RM Module receptacles.

B. Align the RM Module and press it onto the port by

applying downward pressure. There is no polarity

that needs to be observed. Be sure that the connectors

are fully seated.

C. Turn amp on and audition the system. If further

adjustment is necessary, turn amp off and exchange

the RM Module for a higher or lower value.

Warning, the RM Modules will become HOT during

normal use. To avoid burns, caution should be taken

when exchanging an RM Module.

A. Remove the RM Module from the packag-

ing and inspect the circuit board.

B. Locate the two connectors soldered on the

bottom of the circuit board. See illustration 1

C. Simply align the two connectors with the

two circuit board mounted receptacles located

on the 302a and 403a amplifiers and plug the

RM Module into place by applying downward

pressure.

The RM Modules serve two purposes. First they acti-

vate the “passive speaker terminals” on the 302a &

403a and, secondly, they add 4, 8, 12 or 16 dB of atten-

uation to the speakers attached to the “passive speaker

terminals”. Normally, the rear fill speakers are attached

to the “passive speaker terminals” but any speakers (ie

tweeters / center channel) that you desire to attenuate

(turn down) may be attached to these terminals. The

appropriate module is dependent upon speaker effi-

ciency and the distance of the listener to the speakers.

In a mini or standard pick-up truck, where the rear

speakers are in relatively close proximity, the higher

value RM 12 or RM 16 may be appropriate. In a sedan

or coupe, the RM 4 or RM 8 may be better suited. The

modules are easily interchanged and a little experi-

mentation will help you determine the best value.
