Special care must be taken in the PCB-layout to separate pin 9 from the pins 10, 11 13 and 14 to minimize the crosstalk between the clip output

and the inputs.

To avoid switch-on plops, it is advised to keep the amplifier in the mute mode during a period of ≥ 150 ms (charging the input capacitors at pin

10, 11, 13 and 14).
