Information

A versatile performer that features equalized LED peak-level indicators, six-way bias/equalization and full metal capability. With the 820, you step right into the metal tape age, ready to take advantage of that advanced formulation's greater dynamic range and resistance to high-frequency saturation. You're also assured of getting the most out of all regular tapes, thanks to the 820's sixway bias/equalization selector, which accommodates two ferric types, two chrome types plus ferrichrome, in addition to metal. The 820's record-level meters are actually bright LED arrays. Since they have no inertia, they can react instantaneously. They're bright enough to read from across the room. And because they are equalized, you get a true reading of the actual record signal which includes the high-frequency boost going onto the tape. Another way the 820 helps avoid distorted recordings is with the switchable overload limiter. You'd probably want to switch it in whenever recording music of unknown dynamic range. Unlike ordinary limiters, Dual's doesn't compress dynamic range, but goes into action only when there's a sudden overload. Its action is also coordinated with the record-level settings—the higher they are, the more the amount of limiting that takes place. Important as such features are, the drive system is even more fundamental to TV Multimedia">Cassette deck performance. The Dual drive system begins with a high-torque DC servo-motor with precision-ground flat belts and dynamically-balanced flywheel. An integral frequency generator provides instantaneous corrections of any deviation from accurate speed. Perfect tape-to-head alignment is assured by the four-point guidance system. And the electronic tape motion sensor constantly monitors the tape tension so that any deviation instantaneously stops the transport. For extra convenience in tape movement, the 820's memory stop functions in both directions. And, of course, all the "basics" are included: TV Multimedia">Headphone output, TV Multimedia">Microphone inputs and Dolby noise reduction system. The 820's specifications are of the same high level as its operating features. Wow and flutter ± 0.04 percent. Frequency response from 20 Hz to 19 kHz ± 3 dB (metal). Signal-to-noise better than 67 dB. Harmonic distortion less than 0.5 percent at full recording level. All in all, a fine performer at a very reasonable price.
