Symbol
RECO
Function
Receive output attenuator.
This pin is normally ac coupled to the
input of the speaker amplifier
(Pin 19 – SAI)
Receive input attenuator.
Input resistance is nominally 5 k
.
Resistor connected from Pin 28 to
ground determines the nominal gain of
the receive attenuator. The receive
channel gain is directly proportional to
the RG resistance.
