Special care must be taken in the PCB layout to separate pin CLIP from
pins IN1+, IN1 , IN2+ and IN2 to minimize the crosstalk between the CLIP output and
the inputs.
To avoid switch-on plops, it is advisable to keep the amplifier in the mute mode during
in
and results in fast muting when switching off.
