Remote input functionality
The amplifier also can be controlled with a linear taper 10k ohm potentiometer (fully CCW = 0 ohm,
fully CW = 10k ohm) and SPDT switch. When the SW1 switch is set to short the A/B pin to the COM pin,
the amplifier switches to input A. When the SW1 switch is set to make the A/B pin open, the amplifier
switches to input B.
