Well, that must mean that any receiver with this Trinnov system (like the new Sherwood Newcastle R-972 and the upcoming 998), in addition to being able to automatically set the correct trim dB levels for Dolby Digital Reference Level calibration of all your speakers, must also have full range equalizer hardware built into the receiver that can compensate for room interactions that can cause peaks and dips in the frequency response of your speakers at the listening position.

This means you could place the microphone at the listening position, turn on the Trinnov setup routine, leave the room, and when you come back, all speakers, subwoofer included, are now calibrated to Dolby Digital Reference Level and all the speakers are delivering a pretty flat frequency response all across the whole range of frequencies. From your tweeters in your main speakers to your subwoofer. That's pretty impressive, if it actually works that well.
