Personal preference ... but at least the same as the other channels.It can be 1 dB, 2 dB, 3 dB, or even more, than the other channels.If you want more low frequencies volume, set it higher.

音壓係咪即係大細聲?用黎度皇帝位聽到每隻喇叭出聲一樣大細?

Thanks ching's advice
爬文睇過,音壓一般 set within the range of 75db - 80db,
but subwoofer auto setup 過後,音壓已去到 96db to 99 db,响 AMP 再點減個 db 都無可能去到 80db.....{:6_192:}
What should I do, please advice {:6_195:}

想買音壓計

我試過用音壓計同auto setup set三點測試作AB比較,發覺auto setup好準!

Your subwoofer should have a volume knob or something equivalent (my Velodyne SPL-800R is using the remote control to set the subwoofer volume).Try to turn down the volume knob.

75-80 dB is just a guideline.You can set all the front/centre/surr channels to, e.g. 82 dB, and then set SW to, e.g. 85 dB.That's is still perfectly ok.A more important thing is - the volume trim level settings in the AV AMP for all the channels should be well within their adjustable range (usually it is +/- 12 dB); and it is more desirable to set the front channels to 0 dB (which may result a SPL meter reading of, e.g. 82 dB) and then adjust the trim levels of all the other channels to match with that 82 dB.

其實將前置set做0, 定係中置set做0會比較好呀?
因為兩者都有說法! 謝!
