5.1.2 Video Connectors CN8 and CN9
Standard Cinch connectors are used to input the composite video signals for the two video channels 1
and 2. The nominal impedance for each video input is 75
Ω
. The signals are AC coupled to the video
processor via 47 nF capacitors. The nominal video signal voltage level is 1 V
PP
, but due to the auto-
matic gain adjustment within the video processor, signal levels between 0.5 V
PP
and 1.4 V
PP
are
acceptable.
