Super8 Sound Studio
The Lab Recorder is a modified Crown PRO-700 three-motor
tape deck. The record-reproduce electronics are available in
monophonic and stereophonic versions. The Super 8 fullcoat
head assembly is manufactured by Crown to Super8 Sound
specifications. Each Lab Recorder is supplied by Crown
biased and equalized for recording on Super 8 fullcoat magnetic
film, with calibrated frequency response test charts.
The Super8 Sound Laboratory Recorder consists of three
components — the fullcoat transport, record/reproduce
electronics, and sync electronics. A portable case is available
but the three components are designed for rack-mounting
in standard 19-inch racks.
With its one hour running time, the Lab Recorder can do
transfers to the longest available Super8 film loads — 1200
feet. This length facilitates double-system sync transfers from
Super 8 to video with no need for intermediate stops on even
the longest video cassette.

Multiple Fullcoat Recorders
Since any number of Super8 Sound Recorders will run together
in sync with the AC line frequency, any number of
tracks can be mixed, and recorded on a master track recorder
also running in sync. The Super8 Sound Recorders are
started simultaneously in sync by using an AC Common Start
Box or a PhotoStart/BeepStart device, which responds to a
beep tone, and releases each recorder at the same instant.
How to accomplish multiple track mixes with multiple
Super8 Sound Recorders is described in detail in Section
III.G of the Super8 Sound Recorder User's Manual.
With an AC synchronous projector or an AC synchronous
editing table these mixes can be done while watching the
picture in sync. If your projector only has 1/F sync capa-

bility, you can still run up to six Super8 Sound Recorders
in sync with it by using special multiple recorder sync cables.
Post-synchronous sound, e.g. dubbing dialogue or replacing
li nes which are unusable in the original recording, can be
accomplished with two Super8 Sound Recorders with or
without picture.

Catalog for technical details on the Super8 Sound Recorder.

Multiple Track Recorders
Multiple-track tape recorders, used in conjunction with the
Super8 Sound Recorder, allow voice-overs, narration, sound
effects, and music tracks to be added alongside original sync
dialogue or on-location sound effects tracks.
Mixes of up to three sync tracks are readily achieved on quadraphonic
four-channel tape recorders (one channel carries
sync pilotone). Wild tracks may be fed in at the same time,
for example from wild recorders carrying loops of room tone,
wind effects, etc., using a multi-channel mixer.
The most desirable four-channel recorders have independent
recording channels and the capability to record straight
across from a prerecorded track, while listening to that previously
recorded track in sync with the track being laid down
via the record head (and not through a separate monitor or
playback head some distance away, which would introduce a
delay). Such machines are described as having "Syncro-
Trak" (SONY) or "Simul-Sync" (TEAC). In some cases, it is
possible to live with the delay, e.g., at 15ips it usually
amounts to only a couple of frames out of sync, at 7.5ips it
can be four or five frames.
The four-channel recorders listed below have straight-across
sync heads and four completely independent recording amplifiers,
unless otherwise indicated. They all have RCA phono
jack line inputs/outputs and are connected to the Super8
Sound Recorder with a single resolver and transfer cable
that carries sync signals to and from the Super8 Sound Recorder.
