Before preparing the amplifiers, make sure the
amplifier is turned off and the AC mains are
disconnected. Let the unit sit for 3-5 minutes to
allow the electrical charge in the power supply
capacitors to discharge.

Parallel Systems Configuration, Wiring and Balancing
Parallel multi-amp configurations require a ballast resistor
(two resistors for 7796 models) to be mounted on each
amplifier’s back panel and connected to the amplifier’s
OUTPUT connector. Complete the following steps for each
amplifier in your system to install the ballast resistors for
Parallel System setup.
Before preparing the amplifiers,
make sure the amplifier is
turned off for at least 3-5 minutes and the AC mains are
disconnected.

Install Ballast Resistors
4.1.1
Mount and Connect Ballast Resistor
Locate the bracket-mounted ballast resistor(s) in the
1.
Ballast Resistor Kit. Position the bracket on the amplifier
back-panel grill as shown in
Figures 4.1 and 4.2.
Use the provided plastic ratchet fasteners to secure the
2.
resistor mounting bracket to the grill of the amplifier by
pushing each fastener through the bracket mounting hole and into a slot on the grill.
Connect the resistor’s terminal lead(s) to the output connector labeled OUTPUT as shown in
Figures 4.3
3.
and 4.4.
Tighten the screw to secure.
SHOCK/BURN HAZARD. DO NOT TOUCH
BALLAST RESISTORS while the system is
operating. The ballast resistors are not
protected against electrical or heat transfer.
Touching the ballast resistors during operation
can result in severe shock or burn.
