Originally posted by Tom_Bombadil After you use a SPL meter and a test disk to find your 75dB volume setting, some receivers will allow you to then reset your volume control to this being the "0" volume setting. You would have to read your manual to find out how to do this. Oh, and you would want to use your meter to set your speaker level settings first. If you set the overall volume to 0 first, then tweaked all of your speaker volume settings, the final result might be a 75dB setting that is off a dB or two on your volume control from where you started. The receiver cannot possible know beforehand what the volume setting needs to be for your system to be producing a 75dB sound level. Your speakers and your room can affect this by several dB. So there is no factory setting that would prove to be reliable - although they might assume you have speakers with 90dB sensitivity in a medium sized room, and thus come pretty close. |
