As Onkyo's new flagship home network receiver, the TX-NR5009 packs the ultimate in clean power, precise processing, and abundant connectivity. Power is delivered through a massive toroidal transformer and multiple transformers for A/V processing, with the chassis encased in separate panels to reduce vibrations. Gold-plated HDMI terminals, speaker posts, and A/V inputs speak to build quality of the highest order. Video output from the TX-NR5009 benefits from advanced HQV Vida processing, ISF video calibration, and 4K upscaling via Qdeo technology. Audio, meanwhile, is processed via high-end 192 kHz/32-bit TI Burr-Brown DACs, with support for DSD Direct from SACD and DTS Neo:X surround-sound processing. Audyssey MultEQ XT32 gets the most out of movie and game soundtracks and fills your music with energy and pure musicality. As your all-purpose switching center, the TX-NR5009 includes eight 3D-ready HDMI inputs, 9.2-multichannel pre-outs, and an Ethernet port for internet radio and PC audio. Stringent THX Ultra2 Plus quality assurance guarantees stellar performance in even the largest home theater spaces.
