SONY STR-V55 (1979) | Pulse Power Supply

 

Synthesized Art. Sony's STR-V55 receiver from 1979 creates higher-fidelity with a computerized tuner, a DC power amp and Pulse Power Supply (a.k.a. switched-mode power supply or PWM power supply for more technically oriented enthusiasts). The measure of the receiver you invite into your home should feature unusually intelligent versatility. Ample power. Inaudible distortion. And an attractive design that speaks with a quality "finish." The tuner section is so sophisticated that a highly stable quartz-crystal oscillator locks in AM and FM signals for brilliantly faithful reproduction of broadcast programming. And the microcomputer gives you tuning options that simply don't exist any-where else. Memory scan means you press a button and preset stations are automatically tuned in sequence for approximately 3.5 seconds each. Hands-off tuning lets you automatically monitor your favorite stations and simply pressing the appropriate station button tunes in your selection for continuous listening. Choose auto tuning to capture stations with frequencies that you don't know for certain. A touch of a button precisely finds the next station encountered up and down the frequency band. Manual tuning lets you approach known frequencies at high speed and then obtains the exact frequency in precise, discrete steps. And preset tuning instantly recalls any of the eight stations that are stored in our the MNOS (metal nitride oxide semiconductor) memory that can't be accidentally erased. 

Beauty is not only designed for easy viewing, it's coordinated to be proudly displayed. Bright electro-fluorescent digits display frequencies. Bright green LEDs in a five-step array show signal strength. And red LEDs pinpoint your favorite stations at a glance. Consider the power of 55 watts per channel that propels the intimacy of the original performance through Sony's advanced DC amp technology. And a high-gain low-noise phono amp in the preamp section enables you to even use an MC cartridge with your turntable to capture the subtleness of the softest, most delicate music. It's also important to know that an efficient, compact Pulse Power Supply provides stable DC power even at peak levels. And highly responsive Hi-ft power transistors artfully reproduce complex wave forms even at high frequencies and full output power. Sound is so clear that quiet intervals are quiet even at the highest listening levels. Sony's STR-V55 is more of a receiver because you demand to hear more of your music.
