Hi,
I now have my passive subwoofer powered by a Sony STR-DE475 with audio input from the LFE of a Denom AVR-1910.
The Denom AVR-1910 is setup as:
All speakers set to Small.
All bass out of LFE.
The sony is setup so that only the Front L/R and Center outputs are in use (all other outputs disabled) with the subwoofers' three coils connected to each.
The speakers are also set to Large.
LFE is disabled on the Sony to force the bass out through the output connections.
I originally hoped the connections would run:
Denom LFE >> Sony Multichannel IN Subwoofer >> Front L/R & Center Outputs to Subwoofer.
However this never produced any audio (no idea why, the manual for the Sony says its for putting through an already decoded signal which of course the Denom should be, and amplifing it through the outputs which sounded ideal). Because of the lack of sound I found the below works:
Denom LFE > Y-Splitter > Sony CD In >> Front L/R & Center Outputs to Subwoofer.
The reason for the Y-Splitter is that without a R channel input both the center and (naturally) right didn't appear to output sound.
So, this all works - but there's a few odd things happening I'd like to try and sort out but I have no idea where to begin:
1) If I plug a phone into the Sony's CD In, and play a subwoofer frequency test file, it is loud enough to make the furniture shake (literally!) at a volume of 20 (max is 31).
2) If I use the same phone and test file from the Denoms' CD In, and have it pass the bass over the LFE then it's so quiet that I have to have the Sony at 28-31 to hear the lowest frequencies (things are better at a higher range but still not as good as directly plugging into the Sony) and it doesn't shake the furniture as it's alot quieter.
I just wondered if there was any way to get the Sony playing and loudly from the Denoms' LFE as it does when directly connecting?
I did notice that when using the test mode on the Denom (which by default plays the subwoofer at 15db more than I have the master volume set to) then it's a big deep sound, but I haven't seen anything on the Denom to let me adjust just the subwoofer channel. The manual does say you can do it by using the remote control, which of course I don't have - the only channel levels I did find where in the test section, and appear to only affect the test sound - at any rate adjusting the levels to be higher and then trying through the phone resulted in the same lack of bass.
I have yet to try setting the volume to 0db and then adjusting the input source to the Denom, but I still don't understand why it's so much quieter than directly the phone connecting to the Sony.
Thanks.
