Technics new Class A
receivers
Give you so much
because they give you so little. 0,00% switching distortion. 0,00% FM drift
Technics SA-818,
uncommon receiver, because he has it too, synchro-bias circuitry and
quartz-synthesized tuning. Together they give you that special something you've
come to expect from Technics : sonic excellence.
Synchro-bias. What
it does may seem complicated, but it sounds simply beautiful. With conventional
amplifier designs, the output transistors constantly switch omn and off as the
input waveform goes from positive to negative. Technics synchro-bias eliminates
switching distortion because it constantly sends minute amounts of current to
the transistor not in use. And since the transistors don't switch on or off,
distortion is eliminated.so is FM drift because both receivers include our
quartz-synthesized tuning system. With its quartz-crystal oscillator both the
frequencies broadcast and those received are quartz-synthesized so tuner drift
is completely eliminated. So is the hassle of tuning because SA-818 can be
preset to receive eight AM and eight FM stations.
You'll also like
Technics acoustic control because its high and low range boost and filter
switches can attenuate or boost two different frequency ranges.
Technics New Class A
receivers. They give you more what you want and less of what you don't.
