SX-434
15Wx 2 RMS stereo receiver with high-performance tuner and direct-coupled OCL power amplifier.
There is a wide range of Pioneer stereo receivers to satisfy the needs and demands of virtually every audio fan. One of the latest, the SX-434, is specifically designed for those who insist an low distortion but who feel that paying for power they don't need is wasteful. The SX-434 has more than enough power, yet is priced to appeal to budget-consicious music lovers. Its FM section provides an excellent 1.9uV sensitivity (IHF), a capture ratio of 1.0dB (IHF), selectivity of 60dB (IHF), and superb stereo separation of more than 30dB over a 50 to 10,000Hz range. Advanced electronic circuitry throughout includes a low-noise FET and a frequencylinear 3-gang variable capacitor in the FM front end, exclusive IC and phase-linear ceramic filters in the FM IF section and more. The phono equalizer in the SX-434 is high-fidelity all the way, with RIAA equalization of less than ±1 dB deviation. The power amplifier circuitry is the purecomplementary direct-coupled OCL type with wide response and power bandwidth. The SX-434 produces 15W+1 5W continuous RMS power (both channels driven at 8 ohms) with harmonic distortion of less than 0.8% over 40 to 20,000Hz bandwidth. This is enough to drive two pairs of stereo speaker systems individually or simultaneously. Listen and compare. This new Pioneer receiver may just be the value you've been looking for.
HIGH-PERFORMANCE FM FRONT END
The Pioneer SX-434 features top-class FM capabilities. The low-noise FET and frequency-linear 3-gang variable capacitor in the FM front end contribute to the excellent sensitivity of 1.9uV (IHF), improved Image and spurious rejection characteristics and a high signal-to-noise ratio in performance. FM IF SECTION WITH IC AND CERAMIC FILTERS
State-of-the-art techniques are also employed in the FM IF amplifier of the SX-434. Phase-linear ceramic filters and an advanced IC afford a high selectivity of 60dB (IHF) and a capture ratio of 1.0dB (IHF), figures you'd expect from a tuner or receiver in a higher price category.
FM MUTING SWITCH
Annoying inter-station noise can be cancelled during tuning by the handy FM Muting switch.
EXCLUSIVE IC-EQUIPPED AM SECTION
Maximum fidelity and noise-free listening can be enjoyed in the AM band with the IC-equipped AM section of exclusive Pioneer design. RMS CONTINUOUS POWER 15Wx2
The pure-complementary direct-coupled OCL design of the power amplifier section in the SX-434 assures wide frequency response, wide power band
width and satistactorily low distortion. Continuous RMS power over the 40 to 20,000Hz frequency bandwidth (measured with both channels driven into 8-ohm loads) is a stable 15W+15W with less than 0.8% harmonic distortion. TWO-PAIR STEREO SPEAKER FACILITIES
With its ample power provisions, the SX-434 drives up to two independent pairs of stereo speaker systems, one pair at a time or both together. Ideal for powering those remote speakers.
PRECISE RIAA EOUALIZATION
The two-stage direct-coupled NF (Negative Feedback) design of the phon-o equalizer in the SX-434 enables audio reproduction of records within ±1dB deviation from the RIAA characteristic curve.
CLICK-STOP TONE CONTROLS
The BASS and TREBLE tone controls are the click-stop type for convenience in adjustment.
OTHER FEATURES
The control capabilities of the SX-434 are ideal for the average hi-fi set-up: it handles a turntable, tape deck, microphone, AUX and has an output jack for stereo headphone. The provided LOUDNESS contour switch enhances freauencv resoonse at low-volume levels.
