(7-6) Component Out
EURO-AV Component video output check
This check is executed only for European models DVP-
S325/DVP-S525D (except for Australian model)/DVP-
S725D (except for Australian model).
AVD color bar command write → Video (EURO-AV Com-
ponent) OUT
Error: Not detected.
With the Component of video output turned on, the color
bar signals are output from the EURO-AV terminal.
(7-7) Euro AV Through
Euro-AV2 input check.
This check is executed only for European models DVP-
S325/DVP-S525 (except for Australian model) /DVP-
S725D (except for Australian model).
Check video and audio signal pass through from Euro-AV2
to Euro-AV1.
Error: Not detected.
8. Audio
(8-2) ARP → 1930
Error 14 : ARP → 1930 video NG
15 : ARP → 1930 audio NG
(8-3) Test Tone
A pink noise signal is output from the AVD (IC401) through
optical coaxial digital terminal and analog audio terminal.
Error: Not detected.
For DVP-S330 (2ch models):
All channels → 2ch Left → 2ch Right are checked in this
order.
For DVP-S525D/DVP-S725D
(DD models):
All channels → 2ch Left → 2ch Right → Front Left →
Front Right → Rear Left → Rear Right → Center → Sub
Woofer are checked in this order.
Caution: Sub Woofer is checked only for low-frequency
components, and no sound will be heard unless a
proper super woofer is connected.
