Description of the DELTA System (cont.)
remote room and each room keypad's VIDEO button would access a specific VS-3 and
VS-3 output. In this option, the TVs need to be switched to an external input to receive
the central sources. If the client wants to hear the audio through the same speakers
which are used for central music, a CCA-20 Current Sensing TV Amp & Speaker
Switcher or a CCS-3 Current Sensing Speaker Switcher should be used to override the
speakers with the output of the TV whenever the TV is on. If the room is a home theater,
a LLS-2 Line-Level Switcher should be used in conjunction with some type of voltage
controller (CCS-4 or LVI-3800) to trip the input to the room's surround decoder from the
fixed output of a room's RAM-50 to the fixed output of the local TV or central VS-3. The
output of the TV might be used instead of the VS-3, because the TV tuner's audio may
need to be decoded in addition to the centrally switched video sources.
Option 3 - This option is a combination of the previous two options such that a single VS-3 can
provide independent direct switching to two rooms using the VS-3 outputs 1 & 2 (i.e.
Theater and Master Bedroom) while the rest of the house accesses a common non-
simultaneous (independent) output of the VS-3 (output 3). The two independent rooms
wire as in option 2 and the whole house wires as in option 1.
Option 4 - Using the VS-3 as a scrolling selector to gain transport control of video sources even
though the video sources are being modulated for distribution throughout the house.
In this application, the home could be broken into three areas when using one VS-3, to
gain independent control to the video sources over three areas simultaneously. Again,
this option could also be expanded using several VS-3s such that each room can access
a video source for keypad control independently of all other rooms.
Please note, ADA will introduce additional products which will operate with the Delta System.
