JVC KD-D4 cassette deck

 True Convenience Is in The Limelight

Innovative JVC engineers have come up with a truly easy-to-use cassette deck, abounding with sophisticated devices for convenience and fun. Tape operation is smooth and trouble-free with the soft-operating buttons. Peak levels are shown at five frequencies for easy spectrum analysis on a fluorescent tube. The digital readout lets you know metered tape length, elapsed time, remaining recording/playback time, and the order of any selection being played at any given moment. The readout is selectable with a twist of a knob. A deck couldn't be more delightful, more carefree more fun.

 

Two-colour fluorescent SPI: A most useful multi-peak indicator

A spectro-peak indicator is the most useful, most accurate way to set optimum recording levels. It features five bars to show peak levels at five frequencies. In addition, there are two VU-reading bars (one for each channel) as well as one peak-reading bar for the composite output. It's one of the most comprehensive and useful level indicating system ever conceived.

 

Electronic multi-function digital counter: A versatile and useful indication.

The digital counter on the KD-D4 offers multiple functions, all useful and sure to add to your recording and playback delight. In addition to serving as a precision 4-digit electronic tape counter, it works at the twist of a knob, as an elapsed-time counter with a time accumulating function, a counter that displays remaining tape left in minutes and seconds, and an indicator for the JVC multiple music scan system described below.

 

JVC multiple music scan: Skip up to 20 selections to cue in on the one of your choice, instantly.

JVC's multiple music scan system has made selection of a particular song on a tape as simple an operation as on a record. And you can skip up to 20 selections on the way. Once you get used to it, you'll wonder how you ever lived without this feature before.

 

Mechanical logic for soft-touch operation

Trhe tape transport employs a JVC-exclusive mechanical logic system. By the ingenious use of precision cams and gears, the rotational power of the motor has been tapped so that you can enjoy soft-touch button operation for all modes.
