I could use some help in setting up/ calibrating a 5.2 with an SPL.
I can get there three ways:
1) The AVR is a Pioneer VSX-1120-K so it has MCACC to set up 5.1 speakers. Use it in full auto mode.
2) I also have the Disney: World of Wonder HD
(WoW) set up disk with 5 speaker & subwoofer test tones for use with SPL.
3) I can use "Manual Speaker Set Up" with AVR's test tone with SPL.
I bought a cheapo SPL from eBay (AZ8928) and I have been trying to set up the speakers using SLOW + 'C' weighting as many a google threads out there show.
The WoW instructions suggest:
For best results, use a sound pressure level meter to adjust channel levels. A comfortable volume is usually between 78 dB and 85 dB as measured on a Radio Shack or equivalent sound level meter set for C weighting and slow response.
There is the master AVR volume (goes from -80 to 0 dB: where 0 dB is reference) and speaker levels that range from -12 to +12 for each speaker (including SW).
This may sound stupid, but how does one get to 78-85dB with SPL placed at listening position
I set the designated speaker level to -12 and slowly crank up master volume towards 0 dB as the specific test tone is playing to reach 78-85 on SPL?Option 2:
I set the master volume to something more comfortable like -40 to -20dB (reference is VERY loud) and I set the designated speaker level to -12 and slowly crank up the speaker level towards + 12 as the specific test tone is playing to reach 78-85 on SPL? What if I cannot reach 78dB at the selected master volume?
I am using Option 2 but am I missing something?
They also suggest setting the subwoofer(s) to + 3dB above the level used to set up the 5 main speakers. So if I decide to use say 78dB for the 5 speakers, the sub has to be adjusted to read around 81dB on the SPL? Using Option 2? or something else?
