Audio System
VHS HI-FI Sound
Your VCR has two separate sound-recording
systems, the
high-quality
"VHS
Hi-Fi" system
and the standard
"lin-
ear"
system.
With two exceptions
(see "Second
Audio
Program"
and "Audio
Dubbing"
on this page) the same
sound is recorded
by both systems -- on separate stereo
channels
by the VHS Hi-Fi system, and monaurally
by the
linear system. (The linear track is always recorded,
so that
the cassette can be played on a VCR that does not have
VHS Hi-Fi.)
To hear stereo playback, you must connect your VCR to a
stereo amplifier
receiver
or stereo monitor TV using the
stereo
audio
out
jacks.
See
pages
7
and
8
for
connections.
The Hi-Fi/MIX/LINEAR
switch normally
should
be set to
Hi-Fi, because the sound quality from the Hi-Fi tracks
is
much better. The VCR will automatically
switch to the lin-
ear system if the Hi-Fi tracks are vacant (for example,
if
the cassette was recorded
on a VCR that does not have
VHS Hi-Fi).
Recording Broadcast Stereo TV
The basic procedure
for recording broadcast
stereo TV is
the same as it is for normal off-the-air
recording.
Before you begin recording,
be sure the MONO light in
the display unit is off. If it is lit, press the MONO/STEREO
button to turn it off. As long as the MONO light is off, the
STEREO light will come on if the station is broadcasting
in
stereo. Press both PLAY and RECORD to start recording.
Note: if the stereo signal is noisy (from a weak station, for
example) press the STEREO/MONO
switch. This turns on
the MONO light and turns off the STEREO light, and the
audio
you receive will be monaural.
Monaural
reception
may improve
a noisy stereo signal (page 23).
You can use the Timer or XPR for recording
stereo TV.
Just be sure the STEREO/MONO
switch is set so that the
MONO light is off.
Second Audio Program
Some stations transmit a "Second
Audio Program"
(SAP).
The SAP is normally
used for a second
language.
Get
ready to record in stereo as explained
above, and then
press the AUD B SETswitch.
This will turn on the B SET
light. When the station
broadcasts
a Second Audio
Pro-
gram, the AUD B light will turn on. Press both PLAY and
RECORD to begin recording.
The stereo
sound
will be recorded
on the VHS Hi-Fi
tracks,
and the Second Audio
Program will be recorded
on the linear track. Use the Hi-Fi/MIX/LINEAR
switch to
select the one you want for playback: Hi-Fi for the stereo
sound or LINEAR for the Second
Audio
Program.
(The
MIX position
will play both.)
To hear the SAP sound while you are making a recording
or while you are using the VCR's tuner for viewing, set the
Hi-Fi/MIX/LINEAR
switch
to the LINEAR position.
This
will not affect a recording
in progress.
Return the switch
to the Hi-Fi position
to hear the normal audio.
Note: if you play a tape recorded
with SAP on a VCR that
does not have VHS Hi-Fi, you can hear only the sound
from the second audio program.
Audio Dubbing
Audio dubbing is the process
of recording
new audio in
place of the audio that was formerly recorded
on the lin-
ear audio tracks. Audio dubbing
does not disturb the rec-
orded
video and it does not disturb
the audio that was
formerly
recorded
on the VHS Hi-Fi tracks.
1. Plug a microphone
(not supplied)
into the MIC jack
on the back of the VCR, or connect the audio source
to either (or both) AUDIO IN jacks. (Stereo inputs will
be mixed and recorded
in monaural
on the linear
track.)
2. Set
the
TUNER/SIMULCAST/LINE
SWITCH
TO
LINE.
3. Play the tape you intend to modify to the point where
dubbing
is to end and press STOP.
4. Press DISPLAY on the remote twice to display the
tape counter.
5. Press MEMORYto
turn on the memory indicator.
(An
"M" will appear under the counter reading whenever
the memory is turned on.
6. Press RESET to set the tape counter to 0000.
7. Press PLAY and then use 44
SEARCH to locate a
point
a few seconds
before where
dubbing
is to
begin.
8. Release
the
SEARCH
button
and
press
PAUSE
exactly where dubbing
is to begin.
9. Press and hold PLAY.
10. Press AUDIO
DUB and then
release
both AUDIO
DUB and PLAY at the same time. The A. DUB light
turns on.
11. Press PAUSE to begin dubbing.
The VCR will stop at counter
reading 0000. If you do not
want the audio dubbing
to stop at a predetermined
point,
omit steps 3, 4, and 5, and press STOP to stop dubbing.
After you have dubbed
in audio, use the Hi-Fi/MIX/LIN-
EAR switch to select the audio for playback.
You may also monitor the audio being dubbed by switch-
ing to the LINEAR position.
This will not affect the audio
dub.
• Hi-Fi plays back the audio that was originally
recorded
on the VHS Hi-Fi tracks.
• LINEAR plays the audio that you dubbed in.
• MIX plays the audio recorded
on both the Hi-Fi tracks
and the linear tracks. Therefore
you will have "sound*
on-sound"
when you play a dubbed tape using mixed
audio output.
Automatic Level Control
The Automatic Level Control
(ALC) should
be used for
normal
recording situations. However, manual level con-
trol (ALC turned off) is very useful if one audio input level
is much
lower than the other (recording
from micro-
phones connected to your stereo amplifier, for example).
Use the following procedure for Manual Level Control:
1. Use the normal
recording procedure,
but turn off
ALC.
2. Press LEVEL DISPLAY, if necessary, to turn on the
level display.
3. Adjust AUDIO LEVEL for each stereo channel so that
two red segments of the indicators
light occasionally
during
the loudest
parts of the material
you are
recording.
