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.

SAE TWO R3C

 Start out on the right receiver - SEA TWO R3C
If you're about to build a superb hi-fi system, you need a strong start. We recommend the R3C.
Pream, amp and AM/FM tuner. It's all the electronics you need in one compact, self-contained unit.
And it has features normally associated with receivers twice the price.
Examples: Loudness compensation to let you hear full bass and highs at low volume. Separate tuning and signal strength meters. They virtually guarantee perfectly accuraate tuning.
R3C - For a great system, start here.

Features
30 watts RMS per channel at 8 ohms from 20 Hz to 20 kHz with lesss than 0,09% THD
Separate signal strength and center of channel meters for precise tuning.
Full low and high frequency loudness compensation.
A low filter for rumble protection.
