7800 SERIES OPERATION – SECTION 5
Do not attempt to access the Main Board
while the amplifier is running. Turn the
amplifier off and disconnect the AC
Mains before removing the amplifier
front panel.
After turning the amplifier off, let the unit
sit for 3-5 minutes before removing the
front panel. This will allow the electrical
charge in the Power Supply capacitors
to discharge.
Accessing the Main Board
The amplifier Main Board can be accessed by
removing the amplifier front panel.
IMPORTANT: Before removing the Front Panel,
make sure the amplifier is turned off for at least 3-5
minutes and the AC mains are disconnected.
Tool Required
Torx T15 driver

Procedure
1. Turn the power to the amplifier "OFF".
2. Remove the four hex-head screws, located
along the left and right edges of the amplifier
front panel using a Torx T15 driver.
3. Remove the front cover by pulling straight
towards you.
Custom Compensation Network Installation
When the 7548/7794/7796/7796HC amplifier is
used in Controlled-Current mode, the current con-
trol loop is tuned with an RC network. The factory
default network (CC1) provides 68.1k ohm resis-
tance and 47 nF capacitance. If this default net-
work is not adequate for your application and load,
CC2 can be used to install a custom RC network
on the amplifier main board.
First, install components with the required val-
ues in the main board at locations R5 and C2 as
shown in Figure 5.12.
To change the compensation network, locate
Compensation (CC1/CC2) DIP switch (SW#2)
on the main board. Move the switch to the Down
position to enable the path to the custom network
(CC2).
