In this mode, channel A and channel B operate independently (as a conventional
stereo amplifier). The channel A input signal will be output from the channel A
output connectors, and the channel B input signal will be output from the
channel B output connectors.
The D series power amplifiers provide three operating modes: stereo mode,
parallel (mono) mode and bridged mode, you can decide each specific operating
mode according to your actual application circumstance.
