The Advent
model 201 Tape deck is, to our way of thinking, the ideal source for playing
music in the home. It combines the important characteristics of a
high-performance open-reel tape recorder
with the convenience of cassettes. The Advent Model 201 will make
recordings that are indistinguishable from most source material, including the
best stereo records and FM broadcasts.
Of equal
importance, the Model 201 realizes the full potential of the new
"Dolbyized" commercially recorded cassettes, the most significant
source of recorded music since the introduction of the stereo disc. The best of the "Dolbyized"
pre-recorded cassettes are easily the equivalent of the best disc recordings,
and the number of releases will be continually in creasing.
The Model
201 has the ruggedness and day-to-day operating dependability of the best home
recorders, and will maintain its original performance over long and constant
use.
Intro
The Advent
Model 201 is a high performance cassette tape deck incorporating many recent
advances in home entertainment electronics. The most significant of these is
the Dolby System, a patented electronic circuit that greatly reduces the amount
of noise added by the tape during the recording process. In addition the Model
201 incorporates the circuitry to take full advantage of the new
DuPont-developed chromium dioxide tape sold by Advant under the ADVOCATE Crolyn
label.
The Model
210 incorporates more than the usual number of user-accessible adjustments to
permit the serious recordist to achieve the recording quality that, just a
short time ago, was thought possible only with the best and most expensive open
reel recorders.
Specifications
The Model
201 is the synthesis of the various elements required for high fidelity
cassette performance; a heavy duty transport mechanism with stable mechanical
characteristics; low-distortion, low-noise electronics; a high performance
head; the proper use of Crolyn tape, and the Dolby System. A separate low noise
microphone preamplifier is available as an accessory for those interested in
professional quality live recording.
The
transport uses a high-torque AC motor coupled through an intermediate rubber
idler to an oversized, balanced capstan flywheel. In addition to low wow and
flutter, the transport provides very fast wind speeds and an extremely accurate
tape counter for easy indexing of recorded material. At the end of cassette,
the pinch roller and heads are automatically disengaged.
The
electronics, completely designed and manufactured by Advent, adapt many of the
features found previously only in expensive reel to reel tape decks to cassette
circuitry. The dynamic range and Signal-to-Noise ratio in all electronic stages
exceed by a significant margin those of any known tape so that the electronics
in no way limit performance. In fact, the ultimate performance, like that of
the very good open reel recorders, is limited by the tape itself.
