In this 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.
The MAC 2 series 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.
