Gaidin Posted November 27, 2005 Share Posted November 27, 2005 Hello all, I'm running a pair of RP-3's for my fronts on a Denon 3803. As you know, the RP-3's have the built in, 10" subs. For years, I signaling the sub through the speaker input, but recently decided to split the sub-out on my receiver and run directly into both RP's. Now, the two knobs that control the volume and frequency have no effect. The bass is out of control!! I thought I blew them watching War of the Worlds the other night. I've tried turning down the db's in the level controls, but then I find that the subs will sometimes not kick on at all...I'm assuming due to lack of bass signal? should I go back to pulling the sub signal off the speaker connections, or is there a way I can control the bass? Hope I'm posting this in the right spot. Thanks Quote Link to comment Share on other sites More sharing options...
Gaidin Posted November 27, 2005 Author Share Posted November 27, 2005 Okay...a little more info. I was running the input into the LFE input. If I plug them into the Line inputs, then I can control them with the knobs. So my question now, should I be running them through the LFE or Line inputs? My Denon literature is so vague. I don't even know what LFE means... Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted November 27, 2005 Share Posted November 27, 2005 LFE means Low Frequency Effect, its the ".1" of a 5.1, 6.1, etc system. It filters all the bass information into the subwoofer(s). Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted November 27, 2005 Share Posted November 27, 2005 When you run the LFE input, all controls of the powered subwoofer are defeated (I believe). Meaning you have to adjust everything as far as bass output level, crossover point, etc from your receiver. The line inputs will work just fine.

Gaidin Posted November 27, 2005 Author Share Posted November 27, 2005 Gotcha...so I should probably be running into the LFE input then... So, how can I control the volume of the subs? BTW, the Denon website sucks and I was unable to find anything other than a cheesy FAQ and downloadable manual. Quote Link to comment Share on other sites More sharing options...
Gaidin Posted November 27, 2005 Author Share Posted November 27, 2005 Thanks for the feedback wuzzer. One more question...should I split the lines going to the subs and run into both the LFE and Line inputs at the same time? And while I'm at it, this is what the knobs on the sub control say; "Line Level" and "Bass Countour". I'm assuming Line Level is the volume control, but what is "Bass Contour"?

wuzzzer Posted November 27, 2005 Share Posted November 27, 2005 Here's the manual for your speakers: http://www.klipsch.com/media/Products/reference_om.pdf Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted November 27, 2005 Share Posted November 27, 2005 Here's some tips I gathered from the speaker manual: If you use the 'line in' remove the gold straps from the speaker level in and hook the speaker wire into the 'high' input section only. Line in input may be used together with the LFE input. LFE input must be connected to an input that filters out high frequencies (i.e. subwoofer output from receiver) LFE input should not be connected to a full-range (i.e. line out or pre-out from receiver). Configure the speakers as 'Large' or 'Full Range' on your receiver. 'Bass contour' adjusts volume of low frequencies produced by the subwoofer only. Initially set it to 'flat' and then adjust as needed. 'Line level' adjusts entire bass range when using the 'line in' input. Initially set it to 'normal' and then adjust as needed.

toddvj Posted November 27, 2005 Share Posted November 27, 2005 It's been a few years, but when I owned the RP-5's, I'm pretty sure I had them connected via the LFE in. I also did not remove the jumpers. Quote Link to comment Share on other sites More sharing options...
fletcherkane Posted November 28, 2005 Share Posted November 28, 2005 I agree about the denon website being next to worthless. I had an integrated amp that I sold recently. It was early 90's vintage, and there was absolutely no info about the amp on the site. No specs, no acrobat manual, nada. I did not have the original manual, and really had to scour the internet to find a few specs to post on the ebay ad. Annoying! Quote Link to comment Share on other sites More sharing options...
