Help! Denon AVC-A10SE to subwoofer via power amp - how to lower fixed gain it's too loud! Q: I think I need to reduce a line-level phono signal by -20db, how can I do this? Can I make a simple circuit in-line with the phono level 1.1V subwoofer signal to lower the voltage by 25%? i.e. Can I use a simple resistor, or will that give the supplier or consumer equipment impedence problems? Why? ------- I am trying to use a new power-amp with fixed gain to drive my passive subwoofer. I currently get about 88db max with my old power-amp, but can get a cleaner 100db out of the same sub with a new power-amp in place of the "150w" one I currently use. Sub level limiting feature of the Denon amp... The power amp has a fixed input gain at normal, which is too high for me to use the subwoofer output level limiting function on my Denon AV amp. This feature appears to only work up to -18db, according to the on-screen graphics and interestengly translated manual. I really like the sub limiting function as it saves my hearing and listening room being destroyed by overly loud sub-bass, while keeping calibration levels correct. I think I need to lower the peak signal output level lower than the max -18db in order to stop the power amp cracking the subwoofer against it's stops (at about 100db!). I currently use a lower powered amp which has a variable gain, so I can merely lower the amp's input sensitivity to make use of the Denon's subwoofer limiting, which I really like. The problem is the current amp can only drive the speaker to about 88db before noticeable distorsion sets in. I would like to effectively lower the new power amp's input gain. Any help appreciated. regards, Rob.
