Information
Designed for high performance with total reliability at the
lowest possible price for such quality.
The 810 includes every important feature that directly
contributes to fine performance and total reliability, with
little that might be considered "frills." In short, you'll
find the 810 the perfect deck if you're looking for your
first recorder or if you're simply looking for great value.
Among the many features the 810 shares with the
higher-priced Dual cassette decks are the Direct Load and
Lock system (DLL), high-torque DC servo-control motor with
integral frequency generator, twin-belt drive system,
equalized peak reading meters, logic-controlled intermode
switching and foolproof tape protection.
The DLL system is one of those features that will make you
wonder why it hasn't been thought of before. Instead of a
door that's always in the way of the cassette, you have
direct, unimpeded access to the cassette compartment. The
necessary protection for the tape heads is provided by a
shield that swivels out of the way the moment you switch the
machine on. Then you simply place the cassette into the
compartment, where it locks in perfect alignment.
To remove or replace the cassette, you just reach for it and
pull it out. You can even do that while the tape is in fast
forward! The instant your fingers touch the side of the
cassette they activate auxiliary stop switches.
The one area where no TV Multimedia">Cassette deck can afford compromise is
in its drive system. If that's not reliable, nothing else
matters. The 810's drive system has two precision-ground
belts in a vibration-isolating system, plus a high-speed
direct-gear rewind and fast forward. Precise speed control
is assured by a high-torque
DC servo-control motor whose speed is constantly monitored
and instantaneously corrected by feedback from an integral
frequency generator.
If a faulty cassette should ever jam or spill, an electronic
tape motion sensor automatically stops the transport. So if
you've ever been annoyed with such problems, you can now
forget them.
Thanks to the logic-controlled switching you can go from
mode to mode—even to or from fast wind— without going
through stop.
Another way the 810 excells in its price class is in its
specifications. We invite you to compare them with the specs
of decks selling for considerably more. For example, wow and
flutter is 0.045 percent (WRMS) and frequency response
extends from 20 Hz to 17 kHz,
± 3 dB. One of the reasons for the excellent high end
response even with the Dolby system operating is the
switchable multiplex filter. When recording off the air from
stereo FM stations, the filter is needed to suppress the
high frequency sub-carrier which is part of the multiplex
process. When recording from other sources, you want to be
able to switch out that filter, thus extending high
frequency response beyond FM limitations.
Signal-to-noise is better than 66 dB, and harmonic
distortion is less than 0.5 percent at full recording
levels. Other specs, such as erasure factors, cross-talk and
fast-wind times, are identical to those of the higher-priced
Dual decks.
Now you know what we mean when we describe the 810 as
offering "high performance with total reliability" and a
very attractive price.
