Advanced, High Power
AM/FM Stereo Receiver with Tonal Quality-Oriented Design Features.
For a
practically-prieced integrated receiver, Pioneer's SX-750 delivers an
astonishing amount of state-of-the-art. Perfection. Conventionally, receivers
have been considered inferior in terms of performance to integrated amplifiers
and independent tuners. But the SX-750 is bound to after this convention. Its
pre-amplifier, power amplifier and tuner sections give first-rate performance
specifications, the equal in many respects to separate components.
There is an
abundance of power: continuous power output of 50 watts per channel min. RMS at
8 ohms, from 20 to 20,000 Hz with no more than 0,1% Total Harmonic Distortion.
Other design features contribute to the unit's overall stability and
sensitivity. The input/output terminals and circuits of the pre-amplifier/tuner
sections are laid out on one large printed circuit board, a process that
eliminates shielded input cords and enhances overall tonal quality. The front
end uses a dual gate MOS type FET and a 4-gang variable capacvitor for its high
sensitivity and selectivity. The IF section combines up-to-the-minute circuits
and differential amplifier ICs for its high signal/noise ratio and low
distortion.
The SX-750 by
Pionner: innovative, attractive, value-packed - another model of efficiency in
receiver design.
