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.

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.
