INSTALLER-SELECTABLE OPTIONS

The SS730 has several options that can be selected during installation. Jumpers

on the back of the control head, as well as on the printed circuit board inside the

amplifier case, allow the installer to select these various options. These options

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

UNDERSIDE OF THE AMPLIFIER! Lift the top cover upwards. This cover can

be removed completely from the amplifier unit.

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 10 shows two connection examples.
