Fast blanking (input)
Pin 16, + 1V to +3V for fast blanking
switching, 75
Ω
.
NOTE: if an unsynchronised TV picture
results after viewing an external source
(with a fast blanking signal) connected to
AV, this voltage must be removed to return
to TV mode.
Signal selection
Facilities are provided for automatic
switching when the equipment connected
provides switching voltages as follows:
Pin 8: +9.5V to +12V
- Auto switching to auxiliary O/AUX
channel.
Pin 16: + 1V to + 3V–Auto switching to
RGB.

Audio (in/out): 0.5V r.m.s. (nominal)
Input impedance:
≥
10 k
Ω
(20Hz–20kHz)
Output impedance:
≤
1 k
Ω
(20Hz
–20kHz).
