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.

Kenwood KA-80

 KA-80 Hi-Speed DC Integrated Amplifier
A masterpiece of clean, moder design. The swing-down front panel hides all controls not constantly in use. But nothing is hidden from the ear.

 48 watts per chennel, min. RMS, both channels driven at 8 ohms, 20 Hz -20 kHz, with less than 0,02% THD.
Hi-Speed amplifier for faster transient response for unprece dented musical clarity and crispness.
DC design for clear bass reproduction without phase distortion.
Damping factor constant at 120 from Dc to 20,000 Hz
Phono signal-to-noise an outstanding 92 dB for 5 mV input.
Illuminated Power Monitor and Source switches.
Mic/Line mixing with program source.
DC coupled Tone switch provides laboratory-flat response and serves as an effective subsonic filter.
