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.

Pioneer SG-540 (1985)

 Pioneer SG-540 
Seven-band Graphic Equalizer
7 equalizer controls per channel -
The Sg-540 is versatile enough to compensate for room acoustics, speaker response and so on Center frequencies, individually adjustable for each channel, are 60, 150, 400, 1k, 2,4k, 6k, 16k Hz, control range is ±10 dB for each.
LED-lit slide controls -
Graphically show the overall shape of the equaliation curve in effect
Equalizer recording -
Equalized sound may be recorded on a connected tape deck. In this way, scratch and hiss noise can be eliminated as you dub records and tapes.
Tape monitor switch -
Lets you hear a connected tape deck
Low-noise, low-distortion circuitry -
You can add an SG-540 to your hi-fi system with assurance that it improves, not degrades, overall sound quality.
Low silhouette -
Lets you conveniently and easily squeeze the unit into your audio rack or shelf.
