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.

JVC L-E5 turntable

 

Ultimate Tracking Accuracy Combined with Full-Feature Convenience

JVC's L-E5 Linear Tracking Turntable is a masterpiece of miniaturization. Not only were our designers able to reduce outisde dimensions to little more than that of a record jacket (it's only 34 cm wide) but they were able to incorporate the most advanced and most accurate record tracking system in existence into its design. This actually contributed to the clean lines and unostentatious controls that make the L-E5 as much a pleasure to see as to hear.

 

Linear tracking eliminates tracking error, reduces distortion and produces clear sonic images.

The grooves in a phonograph record are the result of a parallel-tracking stuido cutting lathe and that's the way the tonearm of the :-E5 plays them back for yopu. Tracking error is eliminated and with it music marring distortion, intermodulation, crosstalk and poor separation. In the L-E5, a computer aided Electro Dynamic Servo system and a no-contact optical sensor keep the tonearm 90° tangential to the record groove from beginning to end of play.

 


Short low-mass straight aluminum tonearm with integrated dual-magnet cartridge.

The tonearm of the L-E5 is a studey in simplicity, its low-mass design reduces arm resonance and there is no need for the complex anti-skating compensation devices required by standard pivoted-tonearm designs. JVC's New Gimbal Support for the tonearm assures high sensitivity.

 

All tonearm movements are computer controlled via convenient front-edge controls.

The L-E5 is a fully automatic turntable with microcomputer controlled functions - lead-in, cue, return, or repeat. All controls are up front, outside the closed dust cover including the buttons that move the tonearm left and right for total hands-off control.

 

The coreless DC servo motor and JVC FG Super Servo.

Naturally the golden combination of two JVC technologies are employed to assure absolutely stable, cog-free speed accuracy.
