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-5

 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-5, 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.

Innovative Vibration-Resistant Foot Design
The CD-5 features an original foot design for increased vibration damping. Each foot is constructed of diecast zinc-alloy, and is specially mounted to the body to minimize vibration. The point of the foot rests on an independent base featuring a hybrid construction of aluminum and rubber damping material that further prevents the transmission of vibration. These feet not only give the CD-5 an exciting high-tech look, they also contribute to higher sound quality.

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-5 / 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.
 Time Edit
This function is extremely useful when making tape copies of your favorite CDs. Just press the Time Edit button on the remote control and input the total time of the cassette you're using. In seconds, the tracks that will fit on side A will appear on the calendar display. The CD-5 assumes you'll want to record the tracks in order,but if there's extra time it tells you which tracks will fit on the remaining tape and gives you the optionof adding one of them to the programmed sequence. Press Time edit again and the process is repeated for side B. you maximize recording time and never have the frustration of running out of tape in the middle of a selection.

Synchro Dubbing
When the CD-5 is used together with a teac compatible cassette deck, Synchro Dubbing allows you to control both at once. First use Time Edit to select the CD tracks to be recorded onto the cassette, then press the deck's CD Sync button. CD play and cassette recording begin simultaneously, giving you a simple, miss-free recording start every time.

Pitch Control Functions
The CD-5's remote control includes a Pitch Control function that lets you fine-tune the music by increasing or decreasing pitch in 1% steps up to 12%
