Appendix E: Returning Slave Amplifiers to Stand-Alone Use
The configuration settings required for Series system operation must be returned to the factory-default
settings before a Slave amplifier can be used as a stand-alone amplifier. To reconfigure your Slave amplifiers
for stand-alone use, complete the following.
Amplifier Main Board Settings
IMPORTANT: Before accessing the Main Board, make sure
the amplifier is turned off for at least 3-5 minutes and the
AC mains are disconnected.
Accessing the 7224 Amplifier Main Board
7224 amplifiers contain an Access Panel built into the top
cover to allow easy access to the amplifier main board for
configuration of the Master/Slave setting.
On each 7224 amplifier that has been configured for Slave
1.
operation, locate the Access Panel as shown in Figure E-1.
Make sure that all 8 screws are accessible. Remove the
unit from its rack, if necessary.
Using a #2 Phillips screwdriver, remove the 8 screws
2.
located on the top and side of the amplifier.
Remove the Access Panel and set it aside.
3.
Accessing the Main Board on 7548/7796 Amplifiers
The 7548 or 7796 amplifier Main Board can be accessed by
removing the amplifier front panel.
Turn the power to the amplifier “OFF”.
1.
Remove the four hex-head screws, located along the left
2.
and right edges of the amplifier front panel.
Remove the front cover by pulling straight towards you.
3.
Set Master/Slave Jumpers
On the main board, locate the jumpers P1 and P2
(Master/Slave). For Master operation, set both jumpers to the
UP position (upper two pins shorted). See
FigureE-2
for jumper
locations.
Re-install Output Terminal Resistor
For each Slave amplifier that has been configured for Series
– Single Ended Output configurations, it is important to re-
install the output terminal resistor.
On each Slave amplifier back panel, re-install the resistor
connecting the terminals labeled COM (7224 amplifiers) or
SAMPLED COMMON (7548 and 7796 amplifiers) and
CHASSIS GROUND on the output connector. See
Figures E-3
and E-4.
