Pioneer SX-535 receiver

 Advanced stereo receiver featuring 20 watts per channel, min. RMS at 8 Ω  from 40 Hz to 20,000 Hz with no more than 0,8% T.H.D.

Why pay for watts are wasted? The pioneer SX-535 combines practical power with advanced features and high performance to prove that high power is not always the answer when it comes to good high fidelity listening.. The FM tuner section employs a low-noise FET and a frequency-linear 3-gang variable capacitor in its front end to result in a high sensitivity of 1,9 µV (IHF). The FM IF stage uses a 5-stage limiter and phase-linear ceramic filters to boost FM station selectivity to 60 dB (IHF), capture ratio to 1,0 dB (IHF) and Signal-to-Noise Ratio to 70 dB. And to ensure stability under all operating conditions, the FM MPX circuit is the advanced PLL (Phase Lock Loop) type with an IC. Accurate high fidelity reproduction of all sounds is achieved by using a particularly precise phono equalizer in the Pioneer SX-535.. It keeps RIAA deviation within ±0,5 dB. As for versatility, the SX-535 has special circuits for two tape decks (deck 1 to deck 2 tape duplication is possible),, a dual meter tuning system with FM-linear dial scale and other control luxuries. And as for power, the SX-535 is ideal for use in the average-sized listening room with its continuous power output of 20 watts, per channel, min. RMS at 8 ohms from 40 Hz to 20,000 Hz with no more than 0,8% Total Harmonic Distortion. There are no wasted watts in the Pioneer SX-535  a stereo receiver value you shouldn't pass up.
