Getting
closer to digital sound in performance.
It's true
that audio equipment has been becoming more and more elaborate in circuitry
these years. But the more complex circuitry is, the greater there are chances
that the signals will be compromised in the process. So in the TD-V1010TN
cassette deck from the Super DIGIFINE series, JVC took the classic "less
is more" approach. Also in order to
ensure pure and clean sound, JVC has employed a number of ways to damp and
eliminate resonance and vibration.
Vibration-suppressing
mechanical designs
In the
TD-V1010TN, the precision base for the tape drive mechanism is built from rigid
and heavy die-cast aluminum. The front panel is fashioned out of non-resonating
high-specific-gravity resin, which is 1,5 times heavler and 1,7 times more
rigid than the conventional front-panel material. During recording and
playback, the cassette is held firmly in place by a stabilizing pad that damps
resonance and vibration. A metal sheet is attached to the circuit board
supporting the motor to stop the flywheel from vibrating. Further a massive
brass weight is used for a reel recepracle to damp resonance and also improve
rotating constancy. A solid and rigid base supports the entire chassis. Large
insulators isolate the deck from sound pressure and external vibrations. And
control knobs and switches are fashioned out of solid aluminum. This all adds
up to pure and clean sound, especially from digital sound.
Closed-loop
dual-caspian drive with direct-drive motor.
The
TD-V1010TN employs perhaps the most sophisticated tape drive mechanism ever
designed. With this drive, the portion of tape that runs across the heads is
held laut dyring both recording and playback. One advantage of this
sophosticated system is that it shuts out vibration and ther external
disturbances, rsulting in reduced modulation noise. This gives you sound that
is noticeably clearer and cleaner. And it improves head-to-tape contact for
better response. The capstan is driven by a JVC precision high-torque coreless
"pulse servo" motor which does not set up much vibration, further
"cleaning" the taped sound.
3-head
design for best response
The
TD-V1010TN features three independent heads, one each for recording, playback
and erase. This means since the heads are separate, each can be given the
optimum gap width for best response. Moreover, the azimuth, tilt and tracking
can be aligned head by individual head for best results - extended response and
low noise. This discrete 3-headconstruction also enables you to monitor
recordings as they are being made. There are separate circuits for Dolby
encoding and decoding, so you can monitor Dolby-encoded recordings in real
time.
"Fine"
amorphous heads using PCOCC wiring
The record
and play heads in the TD-V1010TN are made of newly developed "fine"
amorphous material, which combines superior high-frequency response and our SA
(Sen-Alloy) head's superior resistance to wear. For higher signal purity and
clarity, we use PCOCC for the coils and leads in the heads. PCOCC is purest
oxygen-free copper with single-crystal-like construction, featuring most
efficient signal transmission and coloration-free sound reproduction.
Elaborate
circuity for purer sound
Dc-servo
playback amp
The playback
amp features a low-noise FET differential input, cascade connection and DC
servo system - an elabortae design usually featured in the phono equalizer of a
quality amplifier. It has improved Signal-to-Noise ratio by 3 to 4 dB.
High bias
frequency.
The bias
frequency is twice higher than normal at 210 kHz. This reduces bet noise due to
interference of audio signals with the oscillator frequency.
Low-impedance
voltage-tracking power supply
A highly
regulated, low-impedance power supply is featured in the TD-V1010TN. Using a
large capacity transformer and electrolitic capacitors, it automatically tracks
positive and negative voltages to keep the ground potential zero and improve
the stability of amplifier circuits. Moreover, our power supply exhibits
extremely low output impedance across the audible frequency range. The result
is even most dynamic musical passages or external noise cannot affect the
steady performance of the power supply.
Separate
circuit construction
In the
TD-V1010TN, the audio amps, power supply and control circuits are mounted on
separate PC boards, and insulated from each other, to shut out interference -
both electric and magnetic. Furthermore, the deck uses circuit boards plated
with OFC to ensure that the most delicate nunces are reproduced precisely. Also contributing to cleaner sound is a
fluorescent display off switch which turns off the display to prevent low-level
digital noise.
