Overview
The Sony SB-V500 is a video/audio selector having 4 sets
of input jacks, 5 sets of output jacks, and tset of monitor
output jacks. The signal introduced via the input jack
selected by the INPUT SELECT switch will be issued from
the monitor output jacks and from the output jacks which do
not correspond to the selected input jack.
+ Dubbings from video equipment (such as a VTR) onto
four different VTRs can be performed at the same time.

+ There are two sets of IN/OUT 4 jacks; one on the front
panel and the other at the rear. The front IN/OUT 4 jacks
may be used to connect equipment which will be
connected and disconnected frequently, such as a video
camera recorder.
The signal introduced via the IN 4 jacks can be issued
from the OUT 4 jacks as well as from the OUT 1, 2 and 3
jacks. When a video player is connected to the IN 4
jacks, dubbings onto five different VTRs can be performed
at the same time.
A composite video signal' input to this unit is
automatically transformed into a Y/C separated S video
signal' when output. (A composite signal is also output.)
* Composite video signa! and S video signa!
The composite video signal is composed of the Y
(luminance) signal and the C (color) signal. When a
picture signal is input and output in the form of a
composite video signal, the picture quality may be
degraded by interference between the Y and C signals.
The Y/C separated signal (or the S video signal) is input
and output with the Y and C signals separated from each
other. As a result, there is no interference between the Y
and C signals, and this offers a high quality picture
recording and playback.
