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-1000

 Introducing the Technics SA-1000. With more power and less distortion than any other receiver we've made: 330 watts per channel minimum RMS into 8 Ω  from 20 Hz-20 kHz with no more than 0.03% Total Harmonic Distortion. But that's only one reason to buy the SA-1000.  Dynamic range is another.
To capture the sheer dynamics of a live symphony, there's an equally dynamic amplifier section. Like 72,000uF worth of high capacitance filtering, separate DC rectifiers, current-mirror loading and direct coupling. The results are impressive: tremendous reserve power, negligible transient crosstalk distortion and excellent stability.
And just for the record, the SA-1000's phono equalizer gives you everything from a super-high S/N ratio of 97 dB.  To a phono input that can handle a 300 mV signal at 1 kHz.
 On FM you'll get outstanding specs plus two RF stages with low-noise, 4-pole, dual-gate MOS FETs, Technics developed fiat group delay filters and a Phase Locked Loop IC in the MPX section.
As good as all that sounds, Technics Acoustic Control makes it sound even better, because it adds low and high range boost and filter switches to enhance the tone controls. There's also a midrange control with a variable centre frequency. And 24 LED peak-power indicators that let you keep an eye on what your ears will hear.
The Technics SA-1000. In the world of receivers, it bats 1000.
