Processing

The Onkyo TX-SR576 offers all of the low-res codecs for both Dolby and DTS. In addition the TX-SR576 adds Dolby Digital Plus decoding should you have a new source that cannot decode this format internally. The TX-SR576 can also handle high-res multi-channel PCM over its HDMI input, but it will not decode Dolby TrueHD or DTS-HD Master Audio in Blu-ray disc soundtracks.

The Onkyo has a well implemented Mono mode that allows you to select from a stereo mix which channel or channels are output. Additional modes on the TX-SR576 are a generic THX Re-EQ mode called "CinemaFILTER", a MP3 enhancer called "Music Optimizer", a "Direct" mode that bypasses all of the Onkyo's processing and a host of generic DSP modes with names like "Unplugged" and "Orchestra".

The TX-SR576 offers great flexibility in fine tuning volume control and surround modes on an input by input basis. The IntelliVolume feature allows for a relative volume trim on each input of up 12 dB in 1 dB steps. Additionally, one can define a default surround mode for each input depending on the input type. The Onkyo offers a "lip sync" delay adjustable in 20 ms increments from 0 to 100 ms or, if you have a compatible display, there is an HDMI lip sync function that will do this automatically. The TX-SR576 also features the Audyssey 2EQ system for room equalization. Audyssey is my current favorite room eq system and is a great addition to a budget receiver like this.
