What is stereo?




There are now two system of high fidelity, monophonic (monaural) and stereophonic. Monophonic is a system that starts from one microphone and is fed through a single high fidelity set. Stereophonic is a double system. Two separate microphones are placed at different sides of the orchestra and two different systems are used to keep the two signals or channels separated. Two separate speakers are used, placed on different sides of you room. Stereo is much like 3-D photography, two slightly different sound reach your ears giving you a new dimension in sound.

JVC KD-D35 cassette deck

Fine Performance Teamed with Advanced Features Metal Cassette Deck

 

In many ways the KD-D35 is equipped to handle just about any taping situation. It's fitted with JVC's Metaperm rec/Play head for ful fidelity when utilizing metal tapes. The LED multi-peak indicators assure optimum recording levels. And for convenience, the KD-D35 is not lacking. JVC's velvety mechanical logic control system gives the deck luxurious soft-touch control. The single music scan system lets you zero in on the next selection ahead, or return to the exact beginning of the one you're listening to. For the money, you can't beat the performance and convenience offered by the KD-D35.

 

Mechanical logic control for soft-touch operation.

Most single-motor cassette decks have piano-key type transport controls, requiring firm pressure so that they engage properly. Not the KD-D35. JVC engineers have come up with a transport design that uses the rotational momentum of the motor/flywheel and a series of precision cams to operate all transport controls. Response is positive and only a soft-touch is required.

 

7-LED multi-peak indicator - one per channel

JVC first introduced their 5-LED multi-peak indicator several years ago to complement the standard VU meters. But the usefulness of the system was so widely recognized with mechanical VU meters altogether in many of our decks and expanded the meters to seven LEDs, more than adequate resolution for accurate reading of peak levels in programme material. Perfect recording levels are a cinch to set with the KD-D35.

 

Single music scan: An extra bonus

JVC's single music scan system iis an extra that should be standard on all decks. Once you use it, you'll see why. Quickly locating a particular section on a tape - the beginning of the one you're now listening to or the beginning of the next one - is a snap; all it takes is a touch of a button or two.

 

Metaperm Rec/Play head is ready for metal tapes.

The introduction of metal tapes required a great change in existing head designs because of the far higher current requirements JVC's metaperm Rec/Play head is fully capable of fine performance, whatever the tape type selected erase heads also required radical redesigning. Our 2-gap ferrite head is designed to give all tapes, even metal, a double dose of erasure, your assurance that tapes will sound quiet.
