Axiom Home Page Forums General Discussion Technical Questions Using DVD calibration disc

I downloaded an Integra 8.3 manual and found the menu options for manually adjusting speaker levels (Speaker Setup => Level Calibration). If your subwoofer is enabled in the receiver it should appear in that menu so you should be able to send pink noise to the sub and adjust its level just like any other speaker.

If the sub does not appear double-check your speaker settings -- maybe the sub is turned off somewhere ?
