If you're enthusiastic about today's less efficient, super-accurate speaker systems, you know you need a very efficient, super-power receiver to drive them. And if your ears are good enough, you know the value of lots of power to handle critical musical passages with any speaker system.
That's why we created the new KR-8010. with 125 Watts per channel, minimum RMS both channels driven at 8 ohms, from 20 Hz to 20,000 Hz with no more than 0,03% Total Harmonic Distortion, you've got all the power you really need.
But more important, the KR-8010 gives you an extremely clean, low-distortion signal at the same time. For example, the Signal-to-Noise Ratio through the phono input is the best you'll find on any receiver (90 dB). Its overall frequency response is matched precisely to the RIAA curve ±0,2 dB. And the tuner delivers sensitivity and selectivity that you'll really appreciate in signal-crowded-cities.
To shape that signal into music, the KR-8010 offers a full range of front-panel control, usually found only in esoteric separates and recording studios. Like tape dubbing while listening to another source. And dual FM muting levels, Mic input and fade control. Bass, treble and midrange tone control. And more.
Features:
Direct-mounted power transistors permit greater heat sink efficiency for cool operation
Exceptionally low-noise phono equalizer with high overload level
4-pole dual-gate MOS FET's in RF stage and 6-element ceramic filters in IF stage for excellent sensitivity and selectivity
New PLL IC in FM Multiplex with Pilot Canceller Circuit
FM Dolby deemphasis switch and 2-level FM Muting switch
Microphone input for overdub on tape and Public Adress
2 tape deck capability with bi-directional dubbing and tape-through circuit
Triple tone controls with defeat switch
Optional CB-14K walnut veneer cabinet, B-14 walnut veneer side panels, or D-10 carrying handles available
