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.

Technics SA-626 receiver

Technics quartz-synthesized receivers

No tuning system on earth is more precise than quartz.

Tune in an FM station with a Technics SA-626 quartz-synthesized receiver and you can be absolutely sure that it will be perfectly in tune. And that station will stay in tune because the chance of encountering FM drift is 0,00% thanks to the crystalline accuracy of technics quartz-synthesized tuning.

Technics synthesized quartz also eliminates the hassle of tuning. Just push a button and you can preset and instantly retrieve seven AM and seven FM stations. And with Auto-scan, you can sample FM stations automatically.

The amplifier in the SA-626 will give you clean, crisp and dynamic sound because of Technics synchro-bias circuitry which completely eliminates switching distortion. By sending minute amounts of current to the amplifier transistors, synchro-bias never allows them to switch on or off. So there's absolutely no switching distortion.

Listen to the SA-626 and hear the sonic purity of synchro-bias circuitry and the crystaline tuning precision of Technics synthesized quartz.
