The Yamaha R-500 is a versatile stereo receiver designed to deliver high-quality audio performance. It features ToP-ART (Total Purity Audio Reproduction Technology) which combines advanced technologies and quality components to maximize sound fidelity. With a power output of 75 watts per channel at 8 ohms (20 Hz - 20 kHz, 0.04% THD), it ensures reliable performance whether driving A and B speakers simultaneously or handling various audio sources. The frequency response ranges from 10 Hz to 50 kHz, allowing it to reproduce a wide range of audio frequencies. The receiver supports dual zone capabilities, enabling playback of two different audio sources in different locations when paired with additional equipment. It includes features like loudness adjustment, a Pure Direct mode that bypasses tone controls for unaltered sound quality, and a record output selector for flexible audio management. Speaker connections use binding posts, and it also supports bi-wiring for compatible speakers. The R-500 is equipped with a phono input for moving magnet cartridges, a mono subwoofer output, and a standard 1/4" headphone jack for private listening. Additional features include max volume adjustment, a sleep timer, and a remote control for convenient operation.
