Quartz
synthesizer digital tuning provides exact and drift-free reception. A choice of
three tuning modes: 14 preset stations (7 FM and 7 AM), up/down manual, and
auto-scan. Digital frequency readout plus analog display. LEDs for signal
strength, quartz-lock and preset channels. New Class A and Linear feedback
amplifier design. Space Dimension Control expands the stereo image to a maximum
of 240°. Dimension and power level dispaly. Input-capacitorless phono equalizer
first stage allows direct MC cartridge connection. Electronic protection
circuit. Protection/safety indicators. Two-way tape dubbing IF band selector.
Soft touch volume control.
Beyond
quartz, the world's most precise tuning system, lies a new ability to expand
sound.
Imagine
you're in a room with Technics SA-828 receiver.
What you
hear is beautiful stereo. Then you activate Technics variable Dimension
Control. Incredibly, the sound begins to move. The stereo image widens to the
point where the music begins to surround you. You're intrigued by its richness
and depth. You're enveloped by a new experience in sound. That's the wonder of
the patented technology in Technics Dimension Control.
Just as
wondrous is quartz synthesis, the world's most precise tuning system. That's
how the SA-828 quartz synthesizer eliminates FM drift as well as the hassle of
tuning. You can even preset and instantly retrive 7 FM and 7 AM stations, all
perfectly in tune.
Another
perfect example of Technics technology is our synchro-bias circuitry. What it
does is constantly send minute amounts
of power to the amplifier transistors. And since they can't switch on or off,
switching distortion is eliminated.
And when it
comes to power, thr SA828 has plenty;
100 watts per channel minimum RMS into 8 ohms from 20 Hz to 20 kHz with
no more than 0,005% total harmonic distortion.
The SA-828
goes on to show its sophistication with a super-quiet phono equalizer, soft
touch program selectors, fully electronic volume control, and a Dimension
Control display that doubles as a power level meter.
