As with the use of a VS-3 as a scrolling input selector, since the video sources do not route back
into the Delta when individual simultaneous video selection is required, special options exist
for controlling the audio path to specific rooms.
Audio Option 1 A & B - Rooms w/TVs that are also using the Delta-88's Amplifier for music.
Since the video sources are routed using the VS-3's outputs, each TV will need to receive its own
composite video signal and stereo line-level audio signal. Thus, the audio only sources are
routed through the Delta, amplified in the Delta and sent to the room's speakers. The video
sources are routed in the VS-3 and sent to the TV. If the TV's audio output is required to play
through the room's speakers, audio to that room will need to be switched locally at speaker
level, instead of at the mainframe at line-level. This is because the Delta-88's room amplifier
can not be used for
amplifying the audio
of the video sources
as it does not have a
processor-loop. To
amplify the audio of
the video sources you
can use the TV's built-
in amplifier along
with a CCS-3 Current
Sensing Speaker
Switcher.
If the TV's amplifier cannot drive the room's speakers, you can use the CCA-20 Current Sensing
Speaker Switcher and TV Audio Amplifier which is fed the TV's variable line-level output.
This will allow the audio output of the TV to be amplified when viewing stations on the TV's
internal TV tuner, viewing a central video source selected on the keypad with the TV set to an
external input, or
viewing a local
video source (local
VCR) with the TV
set to a second ex-
ternal input. Both
the CCS-3 or CCA-
20 will be located
in proximity to the
TV and the speaker
wires need to run
to these devices
and then home.
