VIDEO PRODUCTION, POST PRODUCTION,
AND AUDIO SWEETENING
Mixing audio for video has become a demanding
field, due to the rising sophistication of both the
production facilities and the viewing audience.
With the prol iferation of cable T.V. systems
offering stereo audio feeds as well as the coming
stereo and multichannel T.V. sound (MTS)
systems for over the air programming, the
awareness of the importance of quality audio
will continue to grow. Another rapidly emerg·
ing area of importance is non-broadcast video.
As corporate and industrial telecommunications
expand, the need for improved audio quality
will keep pace. The TASCAM 300 Series has
all the features necessary to fulfill the audio
control needs of the small to medium produc­
tion house or off line editing/sweetening facility.
Virtually all popular brands and models of 1/2"
and 3/4" VCR's and 1" VTR's will interface
directly with the 300's.
Typically, MONO or STE R EO audio signals from
a variety of sources can be mixed simultaneously.
These signals could originate from studio feeds,
VCR's, VTR 's, voice-over (v.o.) mics, turntables,
audio cassette or cart machines, or any other
mic or line level source. The mixed signals can
then be assigned to the master video cassette
editing recorder. Since the 300 Series features
four PGM outputs in addition to the stereo
outputs, multiple master copies of the audio
program may be recorded. These additional
signals may be remixed as clean feeds, without
the normal narration and voice-over mix. These
mix-minus masters can be used for later dubbing
in a second language.
The AUX sends may be used to generate cue
feeds to the v.o. announcer or for connection
to the studio I F B (I nterruption Foldback) or
P.L. (Private Line) systems. The EFF ECTS
SEND and R ETURN sections can be used for
side chains of special audio effects. I n the
example shown, two source VT R 's are shown in
a typical A-B roll editing situation. Two v.o.
mics are also connected as well as two additional
audio sources: a cassette and a cart machine.
These latter two pieces can be used to add mono
or stereo sound effects or wild track ambience
to the final mix. These machines could also be
used to roll effects into the mix live or "on the
fly".

Monitoring of the various mix components
and the final mix is handled through the 300's
comprehensive MON ITO R section and outputs,
while the v.o. cues are taken from the A UX 1
send.
The edit MASTER R ECOR D E R receives signals
from the STE R EO OUTputs while a clean inter­
national dub ( mix-minus narration and v.o.) is
being recorded from PGM OUTputs.
