KA-3700 Integrated Stereo Amplifier
The lowest distortion of any amplifier in its class and full power down to 20 Hz. Overal performance you would expect in a much higher priced amplifier.
Features
20 watts per channel, min. RMS both channels driven at 8 ohms, 20 Hz to 20 kHz, with no more than 0,08% THD.
Oversize capacitors and high-output power transistors.
Power stability with a direct-coupled complementary differential amplifier.
Low-noise, direct coupled phono equalizer (78 dB).
Clik-stop tone controls.
Low boost loudnest control for realistic listening at low and medium volume.
Oversize Volume and Selector controls.
tape monitoring.
Optional CB-3 walnut veneer cabinet, B-5 walnut veneer side panels, or D-5 carrying handles available.
