INSTALLER-SELECTABLE OPTIONS
The SS730 has several options that can be selected during installation. Jumpers

should be set before installation of the unit.
Amplifier Cover Removal
CAUTION: DO NOT OVER-
TIGHTEN SCREWS!
Remove the four
protruding
Philips head screws located on the
top
of the
amplifier unit, and the four
flush
Philips head screws on the
sides
of the amplifier
unit. DO NOT REMOVE THE FOUR
RECESSED
SCREWS ON THE

Auxiliary Input Polarity
The auxiliary input is normally activated by applying a positive voltage to the
wire. If, instead, you would like to activate the auxiliary input by connecting it to
ground (negative), move the “AUX” option jumper from the “Pos. Switching” pins
to the “Neg. Switching” pins in the amplifier unit. (See Amplifier diagram below).
The wiring diagram on page 1 0 shows two connection examples.
