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 D-E5 cassette deck

A Full-Feature Mini Metal Cassette Deck

All cassette decks may look aloke to the uninitated. Take a look at JVC's D-E5 cassette deck. Your first impression that it's smaller than the normal deck is correct. It's down-sized to match the other mini components from JVC. Now take a close look and you'll see full-touch controls. Super ANRS, metal tape capability, two-way JVC "Single Music Scan" system LED peak meters (seven LEDs per channel) and more - all features guaranteed to put the D-E5 in a class by itself. Check out the features of this deck more closely. You'll sold on JVC.

Two-Motor Full-Logic Controlled Tape Transport convenience feature.

Tape transport operation is simpler and more reliable because all models are controled by a full-logic circuit contained inn a JVC-developed IIL integrated Injection Logic) IC. Also featured are the Cue and Review functions that operate even in the Record mode. Playback automatically resumes when either the Cue or Review button is released. Naturally, all control buttons are the feather-touch type. The D-E5 utilizes one motor to rotate the capstan, the other to drive the reels. This contributes to the low wow and flutter , 0,17% (DIN 45 500), of this deck.


 
JVC SMS (Single Music Scan) System facilitates locating the beginnings of musical programmes.

Use the Rec Mute switch to place blank spaces between songs when recording. During playback, use SMS to scan the tape (forward or backward) to locate these blank spaces. When one is reached, the transport automatically goes into the play mode. Truly a convenience feature that'll make you wonder how you ever got along without it before,

Metal Tape Capability for Extra Wide Dynamic Range.

To fully realize the full dynamic range, low noise capabilities of metal tape, JVC designed its own heads and electronics to accommodate it. The JVC SA (Sen-Alloy) Record/Play head is the result of this research. Improved performance with normal and chrome tapes too, is a side product of our "metal" research.

Super ANRS Noise Reduction for more listenable playback.

The D-E5 utilizes JVC's exclusive Super ANRS noise reduction system to improve the Signal-to-Noise Ratio and increase dynamic range. JVC's ANRS, which is compatible with Dolby-B type, is also available.

7-LED multi-peak indicators assure low-distortion recording

Instead of conventional needle-and-scale VU meters, the D-E5 uses two multi-peak indicators, one for each channel. Seven  LEDs are designed to flash on at threshold levels of -20, -10, -5, 0, +3, +6, and +9 dB. They are responsive and accurate, helping you make recording with low distortion.
