OPERATION IN STEREO MODE
The APX2000 provides three operating modes: stereo mode, parallel (mono) mode and bridged mode, you can
decide each specific operating mode according to your actual application circumstance.
In STEREO MODE, channel 1 and channel 2 operate independently (as a conventional stereo amplifier). The channel
1 input signal will be output from the channel 1 output connectors, and the channel 2 input signal will be output from
the channel 2 output connectors.
OPERATION IN PARALLEL MODE
In this mode, the channel 1 input signal will be outputted from the output connectors of both channels. The channel 2
input jack is not used and the channel 1 and 2 volumes can be adjusted independently. Use Parallel Mode when you
want to drive two speakers with only one input signal keeping separate control of the volume of the two channels.
NOTE: Since you are not using the channel 2 input you can use this socket to "daisy-chain" to another amplifier.
