JVC KD-A8
Luxury is
relative in hi-fi -and not always
related to cost. The design concept of the KD-A8 stresses convenience,
versatility and extraordinary sound fidelity. As we hear it, our new
top-of-the-line model has all these qualities, and more;
Metal Tape
Compatible with SA Heads.
Computerized
B.E.S.T. Tuning System for Bias/EQ/Sensitivity Tuning.
JVC S&L

Two-Motor Transport
JVC-Exclusive
B.E.S.T. Tuning System ends tape guesswork.
This unique
system uses a built-in computer to help you get a flat response (40 to 12,5 kHz
±1 dB) from any type or brand of tape. All automatically and all within half a
minute. Ordinary EQ/Bias selectors can't begin to match it. The initials stand
for Bias, Equalization and Sensitivity of Tape. All three factors are sampled
and set for:
Detection of
normal vs. chrome (and "chrome-equivalent") tapes.
Bias
adjustment (for widest possible dynamic range)
High
frequency equalization (for ideally flat range)
Tape
sensitivity adjustment (within ±0,5 dB for proper operation of noise reduction
systems)
Self-detection/self-correction
for errors.
Still more
luxurious JVC features:
Fully
compatible with the new metal Tape format.
Computer
B.E.S.T. Tuning System for the automatic adjustment of Bias, Equalization and
Sensitivity of tape.
Computer
B.E.S.T. Tuning System for the automatic
adjustment of the recording when you are not a t home.
Search &
Lock mechanism to Search for the maximum source signal level and lock the
recording level to the optimum setting.
X-cut Sen-Alloy record/play head for improved
frequency response, minimizing the contuor effect.
2-Gap
Sen-Alloy erase head for perfect compatibility with Metal tape.
2-Motors,
Independent Drive mechanism makes the wow and flutter a low 0,035% (WRMS)
Full-logic

5-LED peak
Indicator (MPI) - peaks instantly displayed in
-10, -5, 0 dB, +3 and +6 dB within one millisecond.
Bias and
Equalizatiom selected with one 3 position tape select switch.
Indicators
are grouped so as to be easy to chek.
Rec Mute
switch, Memory Counter with memory Stop/Play, Timer Standby, Real-Time pause.
Two-Stepped
Gear/Oil- Damped Cassette lid.
Automatic
input selector (Mic - Line)
Remote
Control terminal for optional remote control unit R-30E
Set-up takes
about 25 seconds on the average; the deck automatically records test signals,
samples them, and tunes itself for the actual tape in use. The system, with its
microcomputer brain, is available only from JVC.
JVC's
S&L (Search and Lock) system automatically sets maximum recording level for
carefree taping.
This super
deck is Fully compatible for metal Tape playback and recording.
An amazingly
low 0,035% wow & flutter (WRMS) results from JVC's unique Two-Motor ID
system.
