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-2002

 Kenwood's KA-2002 solid state stereo amplifier highlights all the best Hi-Fi features in compact size. Simply, yet tastefully, designed in appearance, liek all other Kenwood products, the KA-2002 puts quality above all else. Absolutely harmonious in the synchronized performance of all its units, the KA-2002 matches perfectly with the KT-2001 stereo tuner.
 Special Features
Compact-sized Outside
Kenwood's technology and experience has minimized the high-quality stereoamplifier. Its weight is only 10,6 lbs. Its width is 13 inches only. You can handle KA-2002 as you like and position it where you like.

Condensed Inside
All silicon-transistorized circuits provide enough 46 watts IHF power (at 4 ohms) with less than 0,8% distortion and wide 20 - 30,000 Hz power bandwidth.

Precise Tone Control
For each bass and treble control the click type switches are used. They bring accurate increase/decrease by 10 dB (5 steps) each at 100 Hz and 10,000 Hz. The most suitable reproduction can be offered according to your performance or room acoustic condition.

Balance Control
The click stop is equipped at the center of balance Controller so that the «0» balance may be easily pointed out.

Push Type Switched
Loudness, Mode and Tape Monitor are controlled by newly developed, convenient push type switches.
