RinTV
This pin is for input a right audio
signal from the main demodulator in
the TV set. The signal fed into this
pin is presented to RoutTV, Rout1,
and Rout2.
The input dynamic range of this pin
is 6.5 Vp-p and the input resistance is
70 k

VinTV
This pin is for input a composite
audio signal from the main
demodulator in the TV set. The
signal fed into this pin is presented
to Vout1, Vout2, Yout, and Cout. The
same signal is also output from Det
Select as a sync separation signal.
The input dynamic range of this pin
is 2.0 Vp-p and the input resistance is
30 k
.

LinV1
This pin is for input a left audio
signal from an external source (V1
channel). This pin can also be used
for PIP signal input. The signal fed
into this pin is presented to Lout1
and Lout2.
The input dynamic range of this pin
is 6.5 Vp-p and the input resistance is
70
