The Pioneer SX-50, introduced in 1983, is a computer-controlled stereo receiver with a retail price of $380 at launch. It was designed to accommodate emerging audio technologies, supporting inputs for both television audio and compact disc players. The SX-50 is capable of producing 50 watts per channel with a total harmonic distortion (THD) rating of just 0.007%, resulting in a clean sound profile. The receiver features a user-friendly front panel, characterized by numerous push buttons and a large green vacuum fluorescent display, providing an aesthetic reflective of the 1980s style. The controls include sliders for tone adjustments and large buttons for switching inputs. The SX-50 also includes a stereo simulation feature that enhances mono audio sources, making them sound wider and more engaging. The tuner capabilities allow for manual and automatic tuning and can store up to 8 preset stations for both AM and FM bands, making operation intuitive with visual feedback on its display. The rear panel accommodates input connections for a phono, two tape decks, an auxiliary input specifically for CD players, and an input for TV audio. The receiver can manage two sets of speakers and supports bare wire connections for antennas. The SX-50 was part of a lineup that included models like the SX-40, SX-60, and SX-V90, each differing in power output and total harmonic distortion levels.
