This pin is for input a right audio
signal from an external source (V2
channel). This pin can also be used
for PIP signal input. The signal fed
into this pin is presented to R

1
and R
out
2.
The input dynamic range of this pin
is 6.5 V
p-p
and the input resistance is
70 k
.

This pin is for input a chroma signal
from an external comb filter. The
signal fed into this pin is presented
to C
out
.
The input dynamic range of this pin
is 5.5 V
p-p
and the input resistance is
60 k
.
This pin also functions as a audio
mute switch. The entire audio output
can be muted by pulling the voltage
on this pin below 2.25 V.
