Name
Negative Supply Voltage.
Channel 1 Input Signal.
This capacitor works as an integrator, to control the quiescent current to output
devices in no-signal conditions on channel 1.
Negative voltage sense input for overload protection and for automatic quiescent
current control.
Three-functions Terminal.

High Impedance Power-stages Monitor.
Negative Voltage Sense Input for Overload Protection and for Automatic
Quiescent Current Control.
This capacitor works as an integrator, to control the quiescent current to output
devices in no-signal conditions on channel 2. If the voltage at its terminals drops
under 250 mV, it also resets the device from high-impedance state of output
stages.
Channel 2 Input Signals.
Negative Supply Voltage.
Feedback from Output (channel 2).
Out Signal to Lower Driver Transistor of Channel 2.
Out Signal to Higher Driver Transistor of Channel 2.
Positive Voltage Sense Input for Overload Protection and for Automatic
Quiescent Current Control.
AC Input Ground in MUTE Condition.
Positive Supply Voltage.
Positive Voltage Sense Input for Overload Protection and for Automatic
Quiescent Current Control.
