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.

Technics SV-100

 SV-100 Digital Audio processor, designed for use with a VCR, provides very high quality digital audio processing for digital audio recording and playback.  Not only is the SV-100 compact, it weighs only 2,9 kg (net) making it the world's lightest digital audio processor.
This means that the SV-100 is ideally suited for portable use, especially when combined with the matching Panasonic NV-100 VCR.  Its attractive styling also complements other high quality audio components when used in a home hi-fi system.
 Advanced Semiconductor Circuitry for Compact Size
Sophisticated original LSI and microprocessor technology contributes to this processor's surprisingly compact size and light weight. The PCM signal processing LSI (MN6601) contains about 10,000 elements in a 6,08 x 5,58 mm chip; the playback LSI (MN6602) has about 15,000 elements in a 6,46 x 6,18 mm chip; the recording/playback control LSI has about 6,000 elements in 4,48 x 3,62 mm chip.
Together, these tree LSIs are equivalent to about 320 logic Ics. Instead of the conventional separate A/D and D/A converters, a single AD/DA converter is used for conversion from analog to digital and vice versa.  This revolutionary circuitry also means more dependable performance.
 Designed for Quick Precise Control
For quick and accurate adjustment, the SV-100 has a master level control and a stereo balance control. This unusual system is actually the most practical for most purposes such as recording FM broadcasts or Compact Discs. In both cases it is easiest to adjust same time and no stereo balance adjustment is usually needed. The same goes for live recording where the left and right  channel microphones are normally matched. Furthermore, the less used controls are of the slide switch type, so there is little danger of accidental misoperation.

2-Color FL meters for Accurate Indication
In digital as in analog recording, accurate meters are essential for correct recording level setting. However, with digital audio, it is all the more important not to set recording level  too high. Therefore, the SV-100 is equipped with precision FL meters that extend all the way from -50 dB to +6 dB. Since clipping occours above 0 dB, this wide-range metering system lets you see exactly where you should set recording level to avoid distortion. Comparate this with other digital audio processors that give only an "over" indication if recording level is too high.
 Versatile Connection Facilities
The SV-100 has two complete sets of video input/output jacks, one set on the side and one on the rear panel. This lets you use the Sv-100 in a vertical or horizontal position. The matching Panasonic NV-100 VCR has similar connection facilities so that the two are ideally suited for portable use. Of course, the SV-100 can be used with virtually any home VCR (or ¾-inch U-matic type VCR).

Suplied AC power Unit with Handy Video/Audio Switch
TheS V-100i s ready to use right away since it comes with its own AC power unit for home use. This compact  unit is designed to simplify connections while supplying power to the SV-100. It also works as a battery charger for the optional battery packs available for  the SV-100 On the AC power unit's front panel is a "recording" switch that lets you use your VCR for recording TV programs or for PCM digital recording without having to change any connections
 VCR Tracking Check and Battery Check Functions
A front panel slide switch lets you change the display from recording/playback level indication to VCR tracking and battery check indication. The VCR tracking readout tells you how well the video tape recorder's heads are tracking the recorded tracks during playback. You can then adjust the VCR to obtain optimum playback quality. This is particularly important if the tape is being played back on a different VCR from that used for recording. The battery check readout tells you how full the battery is and whether it needs charging.
