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.

Luxman T-117

Luxman T-117AM/FM Stereo Tuner
Luxman tuners offer Computer-Analyzed Tuning which continuously samples the incoming FM signal. The audio Output is automatically switched to "high-blend" when the level is too low for noise-free stereo. In this way, audio quality is improved for most receivable.
Utilizes twin FM detectors for unequaled performance. A calibration button improves the quality of recording from FM broadcasts.
