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.
