This is a video on calibrating your receiver using Audyssey multEQ XT32 room correction on the Marantz SR 7010 9.2 channel av Dolby Atmos DTS X surround sound receiver. Performing this calibration literally makes a night and day difference in terms of the audio and how the surround sound effects someone. This is easy simple sometimes can take a while however really does make a difference. Determining things like delays distances and other aspects of speaker placement and layout issues. In my opinion this is one of the best forms of microphone calibration a receiver can utilize and once performed allows more sound options and sound modes than previously before.
