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.

Pioneer RT-1020L (1973)

Pioneer's advanced new open reel tape deck, the RT-1020L, is designed for tape enthusiasts who wouldn't look or listen twice at even the finest cassette decks, and who are seeking the ultimate of stereo tape performance. Luxuriously constructed with only the finst materials, built for years of rugged and dependable use under all operating conditions.

The RT-1020L offers remarkable cost/performance adventages, a variety of operating conveniences and the versatility that only an expensive machine can provide. Mechanically sound from three-motor tape transport, including six-pole induction motor, to extra-thick chassis and die-cast framework, the RT-1020L delivers the kind of reliability that only a studio engineer would appreciate. precision performance is another aspect of its all-around dependability, for this deck employs a 4/8 pole two-speed hysteresis synchronous motor, unusually accurate capstan - and then adds the new contour-less hyperbolic-type tape heads for high sensitivity and signal-to-noise ratio.

Indicative of its true professional capability, the RT-1020L accepts the large 10½ inch (267 mm) reels, rare for a deck of this attractive price. These extra-size reels permit twice the recording and playback time of ordinary 7 inch reels. You can thus record extra-long symphonies, or other musical performances, without reel or tape changing. And then for four-channel reproduction, the unit is equipped with a four-track in-line tape head and four-channels tapes now on the market. There are many other features, too, that make the Rt-1020L the tape deck buy of the year, no matter which other deck you might have been thinking of buying - and no mater how unlimited is your tape budget. For true tape deck value, no one ever has surpassed Pioneer.
