This unit creates a surround-sound or ambient sound effect
by deriving the reverberant sound information from the
original stereo (or mono) signal and selectively reproducing
it through front and rear pairs of speakers. The unit is
thereby capable of recreating the expansive natural
ambience of a concert hall or movie theater. This is
especially effective with video sources since the picture and
sound reinforce each other.
Not only is this useful with stereo sources—monophonic
video tapes, TV broadcasts, and any other mono sources can
be reproduced with a simulated stereo effect. Simply add
this unit and a pair of rear speakers to easily create a

with video source.
The BGV and microphone mixing functions let you
add music, commentary, narration, and sound
effects to video sound during reproduction or
while copying from one VCR to another. The
microphone mixing control is downstream from
the BGV mixing circuit so when the BGV mixing
on-off switch is ON, youcan add microphone input
to your BGV mix; and when the BGV mixing on-off
switch is OFF, you can add microphone input to
your choice of sources as selected by the
audio/video input selectors. These features make
it remarkably easy to create original sound tracks
for video tapes.
BGV (“background video”):
The term BGV (“background video”) refers to
watching a video source while listening to a
complementary sound source to go with it.

switching.
When one of the three audio/video input selectors
is pressed, this unit automatically switches both
the video and audio signals for that source. For the
VCR 1/tape 1 and VCR 2/tape 2 selectors, both the
input and the output are switched in this way. The
“TV/video” selector only handles input signals.
This system makes it easy to copy and edit video
tapes in either direction between two VCRs.
Furthermore, when the source button is depressed,
the source selected on the connected amplifier or
receiver automatically becomes the input source
and is reproduced through the speakers.
