TO
Output of the transmitter amplifier. Connected through a resistor of 47 to 100 ohm to -L.
Sets the DC-charateristic of the circuit.The output has a low AC output impedance and
the signal is used to drive a side tone balancing network.
TI
Input of transmit amplifier. Input impedance 17 kΩ ± 20 %.
+C
The positive power supply terminal for most of the circuitry inside the PBL 385 82
(about 1 mA current consumption). The +C-pin is to be connected to a decoupling
capacitor of 47 µF to 150 µF.
GR
The control input for the gain regulation in the receiver.
