The AVR 460/AVR 360 is calibrated with theaverage speaker sensitivity in mind; however, different speakers may havedifferent sensitivities. Use Calibration Offset to adjust the calibration of theAVR 460/AVR 360 according to the types of speakers you have.The average home audio speaker sensitivity is 88dB SPL (8 ohms, 1 watt,1 meter). Check the sensitivity specification for your loudspeakers, foundin the owner’s manual or on the manufacturer’s Web site. If your speakershave a sensitivity rating greater than 88dB SPL, increase Calibration Offsetby the difference between your speakers’ sensitivity and 88dB. If they havea sensitivity rating of less than 88dB SPL, decrease Calibration Offset by thedifference between your speakers’ sensitivity and 88dB.To adjust the Calibration Offset, press the AVR Settings Button and scroll tothe System Setup menu, then select it.
