SX-950 FEATURES
LATEST TECHNOLOGY FRONT END
Two dual gate MOS FETs (field effect transistors), RF amplification and a
buffer 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 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 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 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 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 Amplifier
The power Amplifier of the SX-950
is a direct-coupled, pure complementary
parrallel push pull circuit, which uses a differential 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.
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
Components appearance. In comvination with high quality source
Components and Speaker systems, a magnificent stereophonic music system
is composed for providing rich audio enjoyment.
