4.4.1 Level Controls
Each of the front panel level controls has 31
detents for accurately repeatable settings. In
Bridge-Mono and Parallel-Mono modes, the
channel 2 level control should be turned down.
4.4.2 Meter Switches
The meter switches are located behind the front
panel. They make it possible to switch between
the dynamic range and signal level display
modes for the meters, or you can turn the
meters off. From the factory, the meters auto-
matically display dynamic range (which is
computed as the ratio of peak to average output
power). To change these switches, you will
need to remove part of the front panel. A phil-
lips screwdriver will be needed, and it will help
to remove the amplifier if it is mounted in a
rack. Follow these steps:
1. Make sure the amplifier is turned off and its
power cord is disconnected from the AC mains
source.
2. Remove the two screws that hold each end
cap in place and remove both end caps (see
Figure 2.1).
3. Remove the six screws that hold each handle
in place and remove each handle (see Figure
4.2).
4. Remove the dust filter by gently pulling it
away from the front panel.
5. Remove the two screws that secure the lower
half of the front panel and remove the lower
front panel.
6. Locate the meter switches as shown in
Figure 4.3. Set the switches as desired. The left
switch is used to turn the meters on and off,
and the right switch is used to change display
modes.
7. Reassemble the front panel, handles and end
caps in reverse order of disassembly.
8. Install the amplifier and reconnect power.
