BillH2121 Posted January 15, 2006 Share Posted January 15, 2006 When I purchased my HT system a little over a year ago, I was completely new to HT and particularly digital equipment. A friend of mine that works at Ultimate Electronics picked out the interconnects and gave me a wiring diagram to connect my Denon 1705 to the speakers, TV, etc. I just noticed that line to the sub runs from the sub out on the Denon but instead of going innto the digital input on the sub, he split into two jacks and used the analog inputs. Is there a good reason to do this? Why analog over digital input? I removed the Y connection last night and went to the digital input, but haven't had the chace to listen to anything yet. Explanation anyone - or did my friend make a mistake? Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted January 15, 2006 Share Posted January 15, 2006 There's a digital input on your sub?? [:^)] Quote Link to comment Share on other sites More sharing options...
BillH2121 Posted January 15, 2006 Author Share Posted January 15, 2006 Sorry for the confusion - not digital input per se - the LFE input recommended in the Owner's Manual for use with digital processors. I'm asking is there a reason to favor the inputs for analog processor as opposed to the LFE for digital considering my receiver? Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted January 15, 2006 Share Posted January 15, 2006 I believe that with the LFE input it relies on your receiver for the crossover point. If you have an older receiver or amp that doesn't have a LFE output or its own built-in sub crossover then the regular line-in would be the way to go. Does your sub's manual have any recommendation for hookup? Quote Link to comment Share on other sites More sharing options...
BillH2121 Posted January 15, 2006 Author Share Posted January 15, 2006 The Klipsch manual mentions generally what I said above and what you mentioned - that use of LFE input bypasses the sub's crossover and allows the receiver to manage it. I set the crossover on my Denon to 80 Hz. I guess what confuses me is that the guy at Utlimate sold me the Denon with the HT speakers at the same time so should know that the receiver is capable of handling the crossover. I wondered if there might be a reason to prefer the analog L/R over the LFE or if he just was used to connecting them that way? Quote Link to comment Share on other sites More sharing options...
dougdrake Posted January 15, 2006 Share Posted January 15, 2006 In some subs, connecting to both inputs can raise by sub's output by up to 3db. That may be why it was done. Quote Link to comment Share on other sites More sharing options...
BillH2121 Posted January 15, 2006 Author Share Posted January 15, 2006 Doug - do you mean one into the LFE input and the other into either R or L input? Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted January 15, 2006 Share Posted January 15, 2006 No, i'm pretty sure he's talking about using a Y splitter to connect both the L & R inputs. Quote Link to comment Share on other sites More sharing options...
