Curve (1) is valid when the receiving amplifier is not driven or when MUTE = HIGH. Curve (2) is valid when MUTE = LOW and the receiving amplifier
is driven; V

asymmetrical.
The supply possibilities can be increased simply by setting the voltage drop over the circuit V
LN
to a higher value by means of resistor R
