Direct-Drive Cassette Deck. The Performance Approaching Open-Reel Quality
The JVC DD-9 is truly a deck worthy to be termed "professional", if there ever was one. Thanks to our own JVC-manufactured quartz-lock Pulse Servo motor, we've succeeded in practically eliminating wow/flutter; it's only 0,055% (DIN 45 500), the lowest figure ever achieved in a consumer cassette deck. This and other features help you get the highest level of performance - open-reel quality recording performance - from the compact cassette format.
Direct-Drive plus quartz-lock Pulse Servo motor equals (0,055% wow/flutter)
By linking our capstan directly to the motor shaft, we've eliminated all the linkages - belts, cams, pulleys, etc. - found in lesser decks that can create unwanted speed variations known as Wow and Flutter. The low-rpm motor, designed and manufactured by JVC, is used for capstan drive, it has completely eliminated tiny rotational fits and starts known as "cogging" that can audibly tarnish musical reproduction. A quartz-referred servo circuit has been added so that absolute speed accuracy is impeccable.
Computerized B.E.S.T. tuning system - the matchmaker
You can obtain flat response from 40 to 12,500 Hz with a tolerance of only ±1 dB, using just about any tape, all at the touch of a button. The built-in computer matches deck parameters - bias, equalization, and sensitivity - for each specific tape. Distortion and dynamic range are both optimized.
Three-head design specially configured for B.E.S.T.
As you tune the deck to the tape, you can actually attest to the system's effectiveness, for the DD-9 has separate record and play heads (JVC X-cut SA combination Rec/Play heads), allowing you to monitor the tape while you're recording. You can also witness the unusually extended highs, for each head is given an optimized gap.
Dolby C-type noise reduction: Inaudible hiss and distortion free "hot" passages
The newest circuitry from Dolby Laboratories is incorporated in the DD-9 - Dolby C-type noise reduction. At high frequencies, noise (hiss) is reduced by an additional 10 dB (to a full 20 dB of noise reduction)
Two-colour digital fluorescent level meters with peak-hold function.
They are electronically accurate and have a peak-hold function so that instantaneous transients may be analysed for proper level setting during recording.
