Input Section
Each input channel of the System 8/10 PLUS has the following:
• A set of five BNC connectors mounted vertically.
• A six-pin audio connector located below each set of BNC connectors.
• A green LED indicator above each set of BNC connectors ( ) lights to
indicate that this input is selected. (Only one input can be selected at a time.)
With this combination of input connectors, the System 8/10 PLUS can accept any
type of video input format (NTSC/PAL, S-Video/S-VHS or RGBS). Also, each
input can have stereo audio. The System 8/10 PLUS handles signals according to
how they are connected to the input, as well as how the configuration DIP
switches are set. Each type of setup is explained in detail later in this chapter.
When the System 8/10 PLUS is used to switch different types of signals, the
output signal will have the same format as the selected input. That is, RGB and
Sync (composite or separate H&V) will exit through the RGB and Sync output.
Likewise, NTSC and PAL video signals go to the Composite Video output.
Therefore, if multiple signal types are used in the same switcher, the same
multiple outputs must be used by the projector or display monitor. Some displays
receive all signals on the RGBHV port when under switcher control (see the
appropriate connection diagram in Chapter 3 for your projector).
Output Section
The System 8/10 PLUS has three sets of
output connectors, one for each video
format: RGBS, S-Video/S-VHS (Y/C) and
NTSC/PAL (composite video). There is a
green LED to identify which output is active,
as determined by which type of input is
selected. There is also a 6-pin audio output
connector at the bottom, as well as left and
right audio BNC outputs.
_____ If audio comes in on BNC connectors, it
goes out the BNC connectors; if it comes in
on the 9-pin Phoenix® connector, it goes out
the 9-pin Phoenix connector.
Video Loop Back (VLB)
When using Extron’s Sentosa, Lancia, a third-party scan converter or a
Composite/S-Video-to-RGB decoder, the System 8/10 PLUS allows the use of a
single scan-doubler or decoder with multiple switcher inputs to be looped back
through the System 8/10 PLUS and then out again as RGB Sync together with all
other RGB Sync inputs. These video configurations are described in detail later
in this chapter.
Power
Although the power cord connector is on the back panel, the fuse is actually on
the power supply inside the cabinet. System 8/10 PLUS switchers have power
supplies that accept 90-260 VAC, 50/60 Hz line power. No power configuration is
required. The fuse rating is 250 VAC, 2 Amp fast-blow.
