Click 'Upload sample calibration' below to browse to an Audyssey calibration file (.ady) that has the same speaker configuration as your current set up
Haven't measured your speakers with REW yet? Click one of the buttons above to create a 'REW measurement mode' ady file and transfer it to your AVR
The calibration file will reset certain settings on your AV receiver and configure it for correctly measuring your system with REW
You'll need a microphone with its custom calibration file and an HDMI cable from your computer to your receiver
Next, measure all your speakers and subwoofer(s) by using the included Dolby Atmos REW sweeps. You can optionally do so with Dynamic EQ enabled
REW has capacity for storing up to 500 different measurements at as many different mic positions as you like
Ensure your measurements in REW are named correctly and there's only one measurement for each speaker/subwoofer in your system at the end.
Check this dropdown list for a complete list of allowed speaker/subwoofer names in alphabetical order:
Save your measurements and upload REW one of the included target curves of your choice before running the optimization
In REW, go to Preferences > API > Start server
For a smooth optimization process: Keep REW on the 'SPL & Phase' tab and close any open child windows
Running optimization multiple times? In REW, 'Save all', 'Remove all' and 'Open' saved measurements before each run
When all is set, click the 'Optimize calibration' button below and sit back and relax. Your home cinema will be 'transformed' within minutes!
