The test tones are loud enough for the mic to accurately determine the speaker distance and size. The supplied mic has a 3.5 mm jack and quite a long cord for the mic. How would you use a test disc with the auto system? I would doubt if Outlaw will make a FW change to allow renaming of sources. They probably figure that once the 976 is configured there will be no need to display what the source is as the user should know.
