Information

SX-950 FEATURES LATEST TECHNOLOGY FRONT END Two dual gate MOS FETs (field effect transistors), RF amplification and a buffer TV Multimedia">Amplifier between the local oscillator and mixer stages exemplify the advanced technology built into the FM front end. Together with carefully selected circuit components, this provides outstanding performance in terms of sensitivity, overload resistance, image rejection and spurious rejection. In all of its specifications, the SX-950 FM TV Multimedia">Tuner section compares favorably with the most rcspected separate component type tuners. HIGH SELECTIVITY IF STAGES Excellent capture ratio, stable operation and Sharp selectivity are assured by three ceramic filters in the IF stages and 1C limiters. The filters never need realignment and contribute to high reliability against aging and ambient temperature variations. QUADRATURE DETECTOR AND PLL MPX DEMODULATOR A balanced bridge differential TV Multimedia">Amplifier performs quadrature detection of the FM signal. Linearity is assured throughout the frequency band, while distortion bccomcs minimized. Clear and stable separation is provided by the PLL (phase locked loop) multiplex circuit design. REDUCED DISTORTION AM CIRCUIT Careful engineering is also evident in the AM TV Multimedia">Tuner circuit. Automatic gain control in the RF and IF stages, together with a 3-gang variable capacitor and 1C circuitry deliver improved image ratio, selectivity and frequency response, plus reduced distortion. HEAVY DUTY SPLIT POWER SUPPLY The dual positive and negative power supply incorporates extra large 22,000 /iF electrolytic capacitors and possesses plenty of reserve power. Protection and muting functions are included to both safeguard equipment and eliminate power on-off noise. PRECISION RIAA PHONO TV Multimedia">Equalizer Deviation from the RIAA standard is performed within ±0.3dB, while the ability of the phono inputs to accept relatively strong signal levels without distortion (200 mV rms) results in a wide dynamic range. HIGH RELIABILITY PROTECTION CIRCUIT VERSATILE TONE CONTROLS PLUS TURNOVER SELECTORS Active NFB type bass and treble control circuits provide precise and stable control without affecting the mid-range. Turnover frequency selector switches determine the points at which the tone controls take effect, and a convenient tone on-off switch is also employed to allow a flat frequency response to be obtained at any time regardless of tone control and turnover switch settings. This is useful for checking the effects of the phono cartridge, speakers, listening room acoustics, etc. on the spaciousness of the sound. DIRECT COUPLED POWER TV Multimedia">Amplifier The power TV Multimedia">Amplifier of the SX-950, is a direct-coupled, pure complementary parrallel push pull circuit, which uses a differential TV Multimedia">Amplifier at first stage. SX- 950 delivers Continuous power output of 85watts* per channel, min., at 8ohms from 20Hertz to 20,000 Hertz with no more than 0.1% total harmonic distortion. Plently of power is available for rich and stable stereo reproduction. IMPORTANT ADDITIONAL FEATURES Two tape monitor circuits allow two stereo tape decks to be used for recording, playback and tape duplication. TV Multimedia">Microphone input on the front panel adds to versatility and enjoyment. The audio muting switch can be used to temporarily reduce the volume by 20dB when changing records or tapes or for other reasons, without continually adjusting the volume control. Indicator lamps provide clear indication of operating mode. TASTEFUL STYLING COMPLEMENTS HIGH PERFORMANCE The exquisitely designed aluminum front panel is trimmed with solid walnut. Control functions and layout also add to both versatility and top grade TV Multimedia">Components appearance. In comvination with high quality source TV Multimedia">Components and TV Multimedia">Speaker systems, a magnificent stereophonic music system is composed for providing rich audio enjoyment.
