Panasonic SA-5800
From a highly sensitive FM/AM stereo receiver housing powerful direct-coupled ITL-OTL-OCL amplifier and 2-FETs, 1-ics stereo tuner.
Designed to faithfully entertain your ears, you, the discriminating audiophile. This new FM/AM Stereo Receiver highlights all of the exclusive national Panasonic Features: Direct-Coupled ITL-OTL-OCL amplification circuitry and newly developed Differential amplifier circuits reward you with exciting distortion-free audio power. Two highly sensitive 4-pole (MOS) Field Effect Transistors, a Linearly Variable 4-gang FM capacitor, and a costly Monolithic IC in the specially built MPX circuit will gratify your growing need fro selectivity in today's crowded FM world.
Wider frequency response, higher damping factor with lower distortion and noise level, and superb, clear output signal all add up to incomparable stereo enjoyment. The skilfully designed station targeting system, bolstered by highly sensitive tuning circuitry, makes the SA-5800 the most advanced stereo receiver available today. The well-bred child of a close-knit family of electronics wizards, this sensitive instrument effortlessly meets your highest standards.
Powerful 100W Music Power
Lend an Ear & Listen with Care. No sound has ever been so pure and so powerful as that of the SA-5800. These 100 watts of output power are more than sufficient to engulf your whole house in a sea of crystal-pure sound. Whether you want to lose yourself in the driving rhythms of Jazz or the New Rock, or slide into that warm, classical world, let the SA-5800 be your magic Carpet. Its vibrant power will set a crowd swinging to the throbbing beat, or gently soothe the meditative individual.
Reliable, Stable Amplification
Apart from the unique Direct-coupled circuitry, this receiver also features newly developed differential amplifier circuits. No matter how weak the input signal, the amplifier section will magnify it faithfully, in no way impairing its tonal colors. Furthermore, it assures you of rock-stable performance with clean, linear response to all audible frequencies.
Exclusive ITL-OTL-OCL Circuitry
The Tremendous power of the SA-5800 is channelled through a totally new concept in circuit construction. By eliminating the need for the input and output transformers, and the output capacitor, the very source of noise and signal distortion has been eradicated. this new direct-coupled circuitry greatly widens the range of frequency response and boosts the damping factor to new higher levels. it also reduces the signal distortion to the range of imperceptibility.
Clean Full-Bodied Sound
Even the transistors at the heart of this unique circuitry are totally new. Specially selected high performance transistors have been liberally employed throughout, enabling your to fully perceive the richness and grandeur of any musical sound.
The full complement of tone controls gives you the greatest possible range of Bass and Treble selection allowing you to tailor the sound to your most demanding needs and tastes. The volume control will help you to fill your ears with full concert hall stereo reality
Totally Noise-Free Pre-Amplifier
The SA-5800 offers your ears crisp-clear sound rich, in all the perceptible tonal colors. ALL the thanks go to the extremely low-noise transitory (2SA666) and the honestly built 2-stages PNP-NPN directly coupled equalizer incorporated in the pre-amplifier.
Whatever the strength of the signal you feed into theSA-5800, it will respond faithfully, keeping the amplified signal free from any distortion or noise.
Regulated Power Supply
Have no worries. Be assured that the power output of the SA-5800 as in all National Panasonic's top quality audio in its, is perfectly regulated for reliable sure performance. For producing electrifying Symphonic climaxes, heavy Rock, cool Gypsy violins or soft Mood Music, The power supplied to the different component circuits is maintained at the same stable level allowing precisely balanced stereo reproduction and tonal richness.
Two Highly Selective MOS FETs
The SA-5800 features an entirely new FM frontend design. Completely shielded in a subchassis from distortion producing interference and trouble power hum , it houses two highly selective Field Effect Transistors (4-pole MOS type) in both the first and the second RF stages which are perfectly co-ordinated with a linearly variable 4-gang Tuning Capacitor and 4 tuned circuits. This flawlessly engineered design, assures you of unrivalled sensitivity and peak selectivity for collecting any FM station, near or far.
Stage IF Amplification Circuit
Complementing the highly effective FM frontend, is a specially designed 6-stage IF Amplification Circuit employing 5 Differential Amplifiers and a unique 6-element Ceramic Filter. The highly refined selectivity characteristics offered by this advanced 6-stage IF Circuit are unparalleled by any receiver or tuner of this price range. Alternate Channel Selectivity is as much as 80 dB and capture ratio is far better than 1,5 dB
Noise-Eliminating Muting Switch
The SA-5800 is an absolute joy to operate. You'll find that its performance is as clear and smooth as the cool, distinctive lines of its solid teak cabinet. Its pure tones should never be marred by interstation static shocks, hisses or hums. However, if it happens that such noise does interfere with your listening pleasure, just switch on the Muting Circuit. This feature rids the signal of unwanted noise for uninterrupted musical enjoyment.
