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 model 600

New State-of-the Art Engineering with quality as the Only Parameter Puts the Model-600 in a Class by Itself. Featured are High Power. Low Distortion and Two Independent Power Supplies.

The Supreme Series was sold as an exclusive, 'special order only' line in most of the world (some but not all Supremes were available as parts of regular lines in Japan, Belgium and Germany), and was only available from some exclusive dealers in Canada and Califiornia. I am sure many regulars on eBay will feel bad for either missing these or letting them go for a song, as they are the absolute pinnacle of Kenwood's amplifier building knowledge, which has remained largely unsurpassed to this day - these amplifiers are the progenitors of all sought after dual-mono Kenwoods.


Adoption of 3-stage differential amplifier and parallel push-pull ICL, OCL, DC amplifier which employs FET in the inital stage.

Adoption of the ASO detecting limiter and relay system for the protection circuit which protects power transistors and the speaker systems.

Two independent power supply systems installed for right and left channels.

4-stage direct-coupled all-FET equalizer with differential circuit in the initial-stage.

All-FET tone control with the turn-over switches.

Professionalized attenuator type 4-gang volume control.
