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.

Mitsubishi LT-30

The LT-30 is a late mode linear tracking design, thus containing all the advanced technology for tracking precision. It tracks the record precisely as the original masters are cut; in perfect tangency with the groove for the absolute minimum distortion.
The LT-30, also known as the Diatone LT-3, was introduced in 1980 as the pinnacle of Mitsubishi ‘s Linear Tracking turntables. The goal of every linear tracking turntable is to mimic the position of the cutting head as was during the master cut, yet few can track as precisely as the LT-30. Straight-line tracking completely eliminates the problems of tracking error and stylus overhang. Anti-Skating correction is unnecessary because the system exerts no skating force. External forces acting on the stylus are in complete balance. Further, the tangential arm is much lighter than conventional arms, since it is much shorter. For these reasons, the LT-30 transliterates records with unprecedented clarity and amazing sonic accuracy.
Some other features of the LT-30 include
Fully Automatic Operation -Just press play and the arm is set into motion into the lead in groove. It returns to arm rest when the end of the record is reached. Controls are provided to advance the tonearm in either direction as well as pickup/set down.
Auto Record Size Detection -Size of record is automatically detected and correct speed is set. Speed can be manually changed at any time.
Multiple Tonearm Adjustments -Tracking force, tracking angle, tonearm height, stylus height are all user adjustable
Repeat Feature -this feature allows play of the same record repeatedly.
Tracking Error Indicators -a 3 light display shows when optimal tracking is achieved
