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.

Teac CD-3

 Center-Mounted Mechanism
The CD drive mechanism is mounted in the front center of the unit, providing ideal chassis balance and stability. In the CD-3, the large power supply transformer is positioned in the rear center, and the digital and analog blocks are on opposite sides, preventing any interference from degrading sonic purity.

High-Precision 1-Bit Bitstream D/A Conversion
Bitstream Conversion is the latest advance in 1-bit D/A conversion technology. It converts the original 16-bit music data to a high-speed 1-bit data stream, which is then converted into analog signals by the high-performance 1-bit DAC. This 1-bit processing eliminates the main source of non-linearity and distortion, resulting in exceptionally transparent music reproduction, especially of delicate, low-level signals.
The CD-3 also employ a 20-bit 8-times oversampling digital filter. This  sophisticated filter stage eliminates left and right channel interference and even-order high harmonics while maximizing signal-to-noise ratio for incredibly clear sound reproduction.
 CN Servo
Servo feedback is a possible cause of signal noise, which is why these players are designed to require a minimum of servo correction. To protect against any residual interference, they are equipped with Teac's exclusive CN (clean Noise) servo system. It uses a low-pass filter to eliminate potentially de-stabilizing elements from the servo signal, and also helps minimize vibrations in the optical assembly.

Track Focus Holding System (T.F.H.S.)
Teac's unique T.F.H.S. prevents tracking slips and increases stability. Even if the disc surface is scratched or dirty, T.F.H.S. will read tracking and focus error signals accurately while the pickup holds those signals directly in front of the dirty or defective area. As soon as it is passed, the laser continues reading the same track. The result is fewer errors for more accurate music reproduction.
