TAPE RECORDER

The practical cassette has become an accepted recording medium in profes-
sional audio engineering, be it for OB applications, for disc recording or AV
studios, Common requirements of professional users are superb audio per-
formance, reliability, consistent performance to specifications, and stability
in continuous duty - qualities that are also expected of cassette recorders!
With the development of the A721 cassette recorder Studer has succeeded
in satisfying all requirements of professional users. Principal features: solid-
metal die-cast chassis for enduring precision, 4-motor direct drive with dual
capstan and 2 DC spooling motors, microprocessor control for very gentle
tape processing and simple operation, tape counter with digital real-time
indication, modular audio electronics with automatic record parameter cali-
bration, peak program meter with backlit LCD bargraph instruments,
changeover between DOLBY® B&C as standard equipment, including tape/
source monitoring, balanced inputs and outputs, calibrated and uncali-
brated. Suited for 19" rack mounting.

...THE TAPE TRANSPORT
TECHNOLOGY

The construction of the tape transport
clearly exemplifies the high standard of
precision and stability which was set for
the entire unit. Precision has a direct
influence on audio quality especially
where the narrow tape is concerned.
And stability is one of the basic require-
ments of a unit designed for constant
professional use. And yet the A721 has
performance capacity to spare:

0 Tape deck chassis and headblock as-
sembly made of rigid die-cast aluminum
alloy.

0 Four-motor tape transport mechan-
ism: two direct-drive fast responding
spooling motors, plus two high-preci-

sion disc rotor motors for the dual cap-I

stan direct drive.
0 All transport functions managed by
microprocessors.

...THE OPERATING CONCEPT

The A721 is extremely easy to operate, a
fact which clearly contributes to the re-
liability of the machine and which
enables the userto make efficient use of
the comprehensive function repertoire.
To permit fast and error-free operation,
large-surface keys have been provided
forthe primary tape deck functions. The
logical arrangement of the secondary
controls for the audio electronics and
the tape transport control enables the
user to take full advantage of the wide
range of programmable auxiliary func-
tions. The well-arra nged LC display is ea-
sy to read under any lighting conditions
and provides continuous and compre-
hensive information on the real-time
tape position, output level, operating
modes, and machine states.
