Kenwood KR-9400


The KR-9400 is the most powerful stereo receiver Kenwood has ever built, delivering a minimum of 120 watts of continuous power per channel into 8 ohm speakers, both channels driven, 20 Hz to 20 kHz, with no more than 0.1% total harmonic distortion.

The precision equalizer phono preamplifier section of the KR-9400 uses low-noise metal encapsulated transistors to deliver an exceptionally high signal to noise ratio and assure utmost circuit reliability.

The KR-9400 provides extremely high FM stereo separation throughout the audio spectrum, thanks to a newly developed phase lock loop IC circuit incorporated in the stereo FM decoder section, achieving more than 45dB separation at 1 kHz; better than 35dB at all frequencies from 30Hz to 10kHz.

A cool-running power transformer and massive heat sinks form the heart of a dual positive-negative power supply to the high-output transistor stages. This no-compromise design assures safe, cool operation even under continuous full-power output.

I've had my KR-9400 since 1979, and pretty much use it everyday. I've heard a lot of stereos in my life, but I still think my Kenwood sounds the best. It still can flex my windows at volume 7, and I'm sure I could break them at volume 9 with my pair of Jensen CS 315's.

KENWOOD KR-9400 stereo receiver

I found my KR-9400 several years back in like new condition. It's a MONSTER "boomer".
However, I love the "clarity" at various volumes with all types of add on accessories. Adding a high quality EQ along with top notch speakers will only enhance the quality.

The frequency response of this unit is 5 to 40,000 Hz. This is a large frequency range, which will give a deep bass at the low frequencies and sharp treble at the high end. The total harmonic distortion over this frequency range is 0.02%. The power output is 120 watts per channel rated at 8 ohms with dynamic or peak output power at 310 watts. As for power consumption, the unit uses 415 watts at full power and 60 watts at no signal.

Regarded by many to be Kenwood's best of the 1970's...If you find one in decent condition, get it !!!
