1. LOW DISTORTION POWER Amplifier SECTION The power Amplifier section is composed of a current mirror load differential Amplifier, a class-A Amplifier, and an inverted Darlington type pure complementary circuit. The first stage is a transistorized differential Amplifier to which a current mirror circuit is loaded. The current mirror circuit increases the gain at the first stage and assures low distortion and stability. The power Amplifier stage consists of an inverted Darlington type pure complementary circuit to improve the power supply efficiency and to obtain high output power. If DC voltage exceeding specified limit is developed at the output terminal, the protective circuit turns off the relay to prevent the speakers from being damaged. This circuit also functions as a delay start circuit. 2. SEPARATION OF LEFT AND RIGHT CHANNELS POWER SUPPLY This power supply system is of DPS (dual power supply) type with a 2-winding transformer. The power transformer uses a large sized El core to provide excellent regulation. The combination of this transformer and a large filter capacitor forms a dual power supply system to supply power to L and R channels respectively. This power supply system eliminates dynamic crosstalk as well as it assures reliable operation of the Amplifier. The power supply unit for the preamplifier is equipped with a transistorized power voltage regulator to improve the circuit operation stability and the quality of sound. 3. TONE CONTROL CIRCUIT The tone control circuit has FET at the first stage; it also contains dual power supply unit, 2-stage direct-coupled flat Amplifier and bass/treble control circuit. This control circuit is so called BAX type NF control circuit that assures high stability and low distortion. The flat Amplifier is of the ICL (input capacitorless) type to adjust bass and treble tones up to ±7.5 dB at about 1.5 dB steps, thus enabling fine adjustment of tonal quality. 4. ICL Equalizer WITH FET CIRCUIT This circuit is a simplified ICL circuit consisting of FET input Amplifier, class-A Amplifier and pure complementary SEPP Amplifier. The use of newly developed super low noise FET and cleverly designed circuit reduces the impedance of the entire circuit to improve S/N ratio to 86 dB (2.5 mV input, IHF A). The adoption of precision resistors and film capacitors provides RIAA characteristic with error of ±0.3 dB. 5. SPECIAL TAPE-THROUGH CIRCUITRY This unit has facilities for simultaneous recording by two tape decks and for dubbing from deck A to B In addition, Kenwood’s tape-through circuitry allows you to dub while listening to a different program source. This may not be a feature you will use every day, but it is quite practical and will be appreciated when the occasion arises. 6. LARGE POWER METERS VISUALLY SHOW OUTPUT POWER With these full-size Power meters you always know what your Amplifier is doing. You can visually check output and balance channels. A refinement for audiophiles, these meters are large and illuminated for easy reading. Notice that sensitivity is adjustable for operation at both high and low levels to get maximum range in both cases. High: 0.1W to 80W; low, 0.01W to 3W. 7. TWO Speaker SYSTEMS You can attach two Speaker systems and select either or both. 8. LOUDNESS CONTROL This control ( + 8 dB at 100 Hz) boosts especially the low frequency range at a low listening level and offers you splendid stereo reproduction. 9. BALANCE CONTROL This control performs the volume adjustment of right/left speakers and headphones. 10. EXCELLENT DESIGN Kenwood's excellence of design and superior craftsmanship is evident not only in the electronics of the unit but also in all the controls. 11. OTHERS • 41-click master volume to suit audiophiles' tastes. • Subsonic filter of 1 8 Hz, 6 dB/oct.
