hey guys/girls,
i'm sure this question has been asked, but i couldn't find it through search...
when you are doing your speaker calibration with a SPL meter, is there an optimum starting volume? right now i have the unit at 30, and i will normally watch movies between 35-40. as it stands now, all my db setting are way down to achieve a 90db setting through the SPL meter. i'm going to mess around with it a bit more this week, maybe i will stumble on an initial volume i like.
thanks in advance!

The most important thing is that all your speakers end up at the same relative loudness. (You want it to be loud enough that background noise isn't affecting it, and not loud enough to risk damaging your speakers.... which gives you a pretty wide range.) hey guys/girls, i'm sure this question has been asked, but i couldn't find it through search... when you are doing your speaker calibration with a SPL meter, is there an optimum starting volume? right now i have the unit at 30, and i will normally watch movies between 35-40. as it stands now, all my db setting are way down to achieve a 90db setting through the SPL meter. i'm going to mess around with it a bit more this week, maybe i will stumble on an initial volume i like. thanks in advance! |

ok. i got that, but has anyone messed around and figured out if the relative volume at 20 yields a better product, than starting with a relative volume of 30. i haven't done it yet, but i'm guessing if i have the relative volume at "10" and then calibrate to 80db all my db settings will be in the "positive". as it stands now, with the relative volume at 30, all my db settings are high "negative" numbers. i think what that means is when i watch a movie, instead of having the master volume at "40", i may have it at "30".

Since there's never an "exact" science (and since most systems are different, there never will be), this is how I did it with my UMC-1… - In the Speaker Level menu (Setup > Speaker Level), set the "Trim" level of each channel to 0dB. - Set the master volume of the UMC-1 relatively low. - Start the test tone (which will begin with the left front channel). - Adjust the master volume (not the speaker "Trim") until you achieve your desired "reference" level (whether 75 or 80dB) in the front left channel (while still maintaining 0 dB as the "Trim" level). - Take note of the master volume level displayed as this is now your "reference" volume level. - While maintaining the same master volume level, adjust the trims of the remaining channels as needed. Ultimately, your goal should be to establish your "Reference" level with your speaker "trim" set as close to 0 dB as possible using the front left channel as the starting point. Then, use the level "Trim" to balance the remaining channels. Hope this helps...  |
