Installation of SDP module cards.
If you are using SDP (Speaker Drive Processor) modules, you can install them behind the cover on the front panel. To do this, switch off the amplifier and
unscrew the cover on the front panel. Place the SDP modules with the component-side up in the SDP connectors. The upper connector is for channel 1 or mono
bridge mode operation, the lower one is for channel 2. The modules lock into position and do not need to be secured. The ALC2 automatically routes the signals
through the modules once they have been inserted. All SDP modules can be used in normal mode, or in bridge mode. The ALC2 automatically recalculates the
limit thresholds to compensate for the extra gain of the amplifier. Once the modules are installed, put the cover back on.
