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-P100

 For home and studio digital recording appilcations Technics presents the SV-P100 , a wholly self-contained unit with built-in VHS tape mechanism. The Technics SV-P100  is the most compact digital recording system in existence. lt has everything you need to start making the highest quality recordings you've  ever heard. Advanced semiconductor circuitry provides  outstanding performance in a compact package. Plus you enjoy versatile digital  editing features. W ith all this state-of-the-art technology, you'll  be happy  to find that the SV-P100 is just as easy to use as an ordinary cassette deck-perhaps easier.
 High-Density LSls for Compact Size
State-of-the-art semic onductor technology is the  key to the compact dimensions of the SV-P100, the world's smallest digital recording system. Three original  LSI c hips handle virtually  all  of the signal  processing including digital-to-analog and analog-to-digital conversion. They also take care of error detection,  error correction, video signal modulation and time-base correction. Since these take the place of thousands of transistors and hundreds of  lCs, circuit size is dramatically reduced.

Built-in VHS Mechanism
Built into the SV-P100 is a very high quality VHS video tape transport mechanism with advanced video heads and quartz locked direct drive motors. Basic operation is just like on a conventional cassette deck, with the comfort of microcomputer feather-touch control keys. You simply put a cassette into the front loading compartment and press the rec and play buttons together to begin recording. The cassette door is motor driven for smooth, silent operation when you want to load or eject a cassette.
Multi-FunctioN Display
There's adigital LCD tape counter display, bright FL recording/playback level display, and indication for all functions that you might need. The FL  level display uses fluorescent display tubes to provide very accurate indication of recording level. Besides instantaneous peak indication, it also has  peak-hold which shows  you the highest signal peaks reached in each 2 -second period. T his makes it much easier to set optimum recording level. Another valuable feature is the playback data check indication which gives you a readout of playback signal quality
 Versatile Editing
Since the digital signal is recorded on the tape's video tracks, the space usually used for audio is left free. The SV-P100 uses these extra tracks for "jump" and" search" marks.  This gives you a kind of electronic editing ability that is not possible in ordinary cassette decks. Record a jump mark along a specific section of the tape and the deck will automatically bypass that section at 8 times normal speed.  Normal playback resumes after the end of the  jump mark. This is useful when you want to skip over undesired portions of a recording. Search marks let you rapidly locate specific points on the tape. The tape will advanced to the nearest search mark at 8 times normal speed and then stop. lf you press the play key with the search key, then playback will begin when the search mark is reached.
You can record as many search and jump marks as you want, using the convenient editing levers. Since these marks remain on the tape, you can take advantage of this convenience every time you listen to a recording. Of course you can also selectively erase search and jump marks (by pressing the "clear" lever) as required.
In addition to all this,you have the "locate" function which serves as a memory linked to the tape counter. But unlike on conventional cassette decks,  you don't have to set the counter to zero. This memory stores the actual tape counter number at the instant you press the locate button. The tape will then stop (or begin play)att he memorized position. You can also check the locate memory position by pressing the recall button.
