Kenwood KA-6004


The Kenwood KA-6004 achieves an overall high level of reliability in every performance phase.

If only the strictest requirements are met by each component, then they are included in the full assembly potential of this outstandingly unique amplifier.

For example, the pre-amplifier uses a new type of can seal (metal cased) transistor which is capable of off setting the usual characteristic deterioration in signal to noise ratio resulting from humidity and temperature wear.

Low noise PNP transistors have been attached to the top of the equalizer circuit. Also, super high nichrome evaporated metal film resistors have been used in the feedback circuit in the equalizer stage. These same resistors are also equipped in all other significant circuits to vastly improve signal to noise ratio.


Power output: 40 watts per channel into 8Ω (stereo)

Total harmonic distortion: 0.5%

Damping factor: 32

Input sensitivity: 3mV (mic), 2.5mV (MM), 200mV (line)

Signal to noise ratio: 70dB (mic), 68dB (MM), 75dB (line)

Output: 200mV (line), 40mV (DIN)

Speaker load impedance: 4Ω to 16Ω

Dimensions: 435 x 153 x 300mm
