While there are many different ways to connect your source equipment to your VHD-4403
ULTRA, the examples shown above are the most common and are recommended by Runco.
• COMPOSITE VIDEO INPUT:
Composite video is the most common type of signal used, but is also the lowest in picture
quality. Many sources have outputs that are limited to composite video, such as most VCR’s
and some camcorders; others such as Laser Disc players actually produce slightly better
results when using composite video. While the VHD-4403 ULTRA has an excellent decoder
for composite video, it is recommended that composite video be used only if necessary.
• S-VIDEO INPUT
S-video is the second-best type of signal that can be used, but is MUCH better than compos-
ite video. Using such sources as Satellite receivers, high-quality VCRs and DVD players (with
no component output) will produce a MUCH cleaner and sharper signal. Decoder artifacts
that are associated with composite video (dot crawl and ‘rainbows’) are non-existent when
using S-video.
• COMPONENT INPUT
Component video is the best type of signal that can be used. The most common sources that
use component outputs are DVD players, and it is highly recommended that component be
used when possible. Component video goes one step beyond S-video in picture quality; chro-
ma (color) information is more resolved and the overall picture appears more well-defined.
• PASS-THROUGH
This input is used to ‘pass-through’ any high-definition or computer signals that do not require
processing. The signal by-passes the VHD-4403 ULTRA’s processing and is sent directly to
the projector. The pass-through may be used for COMPONENT outputs from a DTV decoder,
a progressive-scan DVD player or RGB outputs from a computer.
