JVC KD-A33 cassette tape deck


Metal-compatible cassette deck

If you've found that an affordable price usually means a sacrifice of performance, take heart. The JVC KD-A33 metal compatible cassette deck includes much of the technology found in our most expensive decks. Yet it happens to be one of our least expensive decks.

For example, it uses Sen-Alloy heads. These JVC-developed heads handle tremendously high currents with ease, so they're especially well  suited for recording and erasing metal tape. And SA's superb electromagnetic and physical properties give you accurate frequency balance, superb extension and low distortion through years of use.

When you use metal tape with the KD-A33, you'll get all the performance you expect from metal . But when your budget  dictates using a less expensive ferric-oxide tape, you can still get metal-like sound thanks to another JVC development - Super ANRS.

In recording, Super ANRE reduces the level of high-frequency signals so the tape can handle them without, saturating, in playback, it boosts them back to their original level. As a result, sounds like cymbal crashes, trumpet blast, and spoken sibilants (normally the downfall of cassette recording) are reproduced with astonishing clarity and fidelity to the original

 

 
And like our most expensive decks, the KD-A33 has logic-governed solenoid transport controls. You can switch directly between modes, even from "rewind" to "fast forward" with just a light touch of a switch. The KD-A33 also has provisions for adding a timer device and optional remote control.
