Optionally, the amplifier can be placed on a
bench top; please keep in mind that the protective
powder-coating can be scratched when placed
on other equipment or on a bench top, especially
when there is dirt present. To protect the finish, a
set of rubber feet is included in the toolkit that can
be installed on the bottom of the amplifier.

NOTE: The 7548/7794/7796/7796HC amplifier
comes with a factory-installed 2.7-ohm, 2W, 5%,
metal-oxide resistor connecting the terminals
marked “SAMPLED COMMON” and “CHASSIS
GROUND” (see
Figure 2.2
). This resistor should
NOT be removed. WARNING: Removing this re

sistor can cause dangerous output and/or damage
to the load unless configuring multiple amplifiers in
series. See the

ELECTRIC SHOCK HAZARD.
Output potentials can be lethal. Make
connections only with AC Power OFF
and input signals removed.
WARNING

Do not operate the amplifier in a small
sealed chamber of any kind. Improper
operations and overheating will result.
CAUTION
2.4 Connecting the Load
Before connecting the amplifier, make sure the AC
power cord is unplugged.
This section describes output wiring to the load
when using the default amplifier configuration:
Single (or Master) amplifier operated in Controlled
Voltage mode. The amplifier also can be field-
adjusted for operation in Controlled Current mode
or for operation as a Follower amplifier in a multi-
amplifier system. These alternate configurations
