The LX500’s back panel is equally rugged and sports high- quality connectors, with plenty of room between them for plugging in thick cables. Dual HDMI outputs are provided, one supporting video and audio, and another for audio-only connections. Unfortunately, the LX500 lacks an HDMI input—a distinguishing feature found on Oppo models that let you use the player’s video processing and scaling with external HDMI sources.
Pioneer’s Precision Quartz Lock System (PQLS), a feature provided in the company’s A/V receivers, is used to eliminate jitter in HDMI connections. The LX500 also has a “Zero Signal” terminal that supports a ground connection between the player and Pioneer gear featuring a similar terminal.
