Kenwood KA-4002

 Solid State Stereo Amplifier Kenwood model KA-4002

Is the solid state stereo amplifier that packs a compact-sized wallop. With 95 watts and intensely low-low distortion, this instrument guarantees top-level performance of the highest proportions. Another remarkable example of kenwood complete, high-quality circuitry, the KA-4002 also stresses modern, up-to-date design with its simple stylized exterior. Its unbeatable craftmanship makes this model another testimony to Kenwood deserved world fame.

 Special Features

Compact-sized outside

Kenwood has thoroughly researched what is really needed for a stereo amplifier and what is not. The KA-4002, one of the smallest high-quality amplifier in the world is a product that only Kenwood can achieve. It is quite care-free for setting.

Condensed Inside

You could not imagine the inside of KA-4002 from its size. The all silicon-transistorized circuitry provides abundant 80 watts IHF power (at 4 ohms) with less than 0,5% intermodulation distortion and wide 18 - 30,000 Hz power bandwidth.

Speaker Selector

Two sets of speaker system can be connected and selected by the switch on the front panel. They can also be driven together.

Precise Tone Control

For each bass and treble control the click type switches are used. They bring accurate increase/decrease by 10 dB at 100 Hz and 10,000 Hz. You can arrange most preferable performance according to the listening condition.

Two Input Jacks for Phono

You can use 2 sets of stereo player. In addition, you can combine the second tuner or stereo cassette deck because KA-4002 has 2 input jacks for Aux.

Tape Dubbing jack

The tape dubbing jack on the front panel makes it possible to connect the second tape deck and to dub from another deck.

Other Features

Stereo headphones jack, High, Low filter and Loudness, Mono output jack.
