Author Topic: Denon Surround Receiver Problem Bobby Henderson "Ask me about Trajan." Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 05-24-2005 07:00 PM                     I'm looking for some help from people familiar with Denon receivers, particularly the model I mention below. One of my friends has a Denon AVR-1705 receiver with a set of Klipsch speakers connected. He has a problem with the audio in his left and right speakers. It seems as though the speakers have only high frequency audio coming out of them, and at low volume. The center channel and surround channels sound normal. I can't seem to figure out what could be causing this problem. The L, R, LS & RS channel speakers are identical (small 8 ohm bookshelf speakers). The center channel speaker is somewhat similar in design, but has two large drivers instead of one. The speakers in the front are connected using Monster Cable. The surrounds are connected with standard (and cheaper) speaker wire. Overall, it just sounds like the left and right channels are almost missing from just about any 5.1 mix. Is there some kind of crossover setting or tone bypass thing or some other goofy crap that could be causing this?  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

Some would say it was unnecessarily violent, but the fight scenes also had a humorous touch to it. More nudity would have been better though. Overall not bad mindless entertainment.  |  IP: Logged David Stambaugh Film God Posts: 4021 From: Eugene, Oregon Registered: Jan 2002 posted 05-24-2005 07:11 PM                        Besides the fact that it was making me simultaneously sleepy and angry, there was a problem with the sound. I got fed up with it and walked out. =================== Phase problem? (oops, DSpicer already suggested that). What happens in other non-5.1 modes, like ProLogic and plain old stereo?  |  IP: Logged Darryl Spicer Film God Posts: 3250 From: Lexington, KY, USA Registered: Dec 2000 posted 05-24-2005 07:12 PM                    For some reason this is in the wrong forum so someone will move it soon. But til the a couple of questions. Did you friend unhoo the speaker cables for any reason and put them back on out of phase. Has your friend tried switching wires putting the left or right channel to the center and putting the center to one of the left or rights to see if anything changes.  |  IP: Logged Brad Miller Administrator Posts: 17775 From: Plano, TX (36.2 miles NW of Rockwall) Registered: May 99 posted 05-24-2005 08:37 PM                     I must disagree with Michael. This movie flat out sucked. And who names their kid "Denon"??? Hollywood at it's worst. I think I will move this into the proper forum.  |  IP: Logged Bobby Henderson "Ask me about Trajan."

I was in a rush to go somewhere and quickly wrote the post, and thought I hit the "afterlife" button. Anyway, this is a pretty odd problem with my friend's receiver. I don't know what could be causing this issue.  |  IP: Logged Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 05-25-2005 06:18 PM                        OK my big problem here is trying to decipher what the freakin' hell Micheal's post is talking about. Using my vastly superior intelligence, I must assume that this thread was once in the Movie Review forum. Damn I'm smart. But now those posts have no relevance, and tat makes me sad, and also makes me want to ban someone at random. Bobby, It sounds like the receiver is set to channel the lows into a subwoofer. Try telling it that all speakers are "large". Also, make sure they are hooked up properly. Do you have them hooked to the "B" speaker connections when the "A" speakers are turned on?  |  IP: Logged Mike Olpin Chop Chop!

Are you using a "satalite" style subwoofer and front system wherin the left and right is passed first to s a subwoofer, and then onto the L & R speakers? Those types of subs tend to grab a lot of power out of the fronts.  |  IP: Logged Jeffry L.

Posts: 10973 From: Lawton, OK, USA Registered: Apr 2001 posted 05-26-2005 07:25 PM                     This past weekend I tried a number of things to troubleshoot the problem. The very first thing was setting the L and R speakers to "large". That didn't really have any effect. A pair of outdoor Bose speakers were wired to the "B" pair of L and R channels. We tried unhooking them. The problem still remained. I didn't have time to try a couple obvious tests to see if there are blown drivers in the L and R speakers or seeing if perhaps the speaker wire for the L and R channels is bad. With the audio problem being identical in both the L and R channels I have to think there's something going on in the receiver. Either there is some stupid setting that has the speakers switched this way or something is defective. ***update*** I got my friend to switch the speaker leads to his center channel speaker with the L and R speakers and check the test tone. Yep. He has blown drivers in both his L and R speakers.

Hope he has VERY friendly neighbours!  |  IP: Logged Andy Summers Master Film Handler Posts: 397 From: Bournemouth Dorset United kingdom Registered: Jun 2005 posted 07-15-2005 06:56 AM                 Very little experience, hell I won’t let him loose on my home THX sound system, although he may have been playing it at the normal levels like reference 0db level or -10db, but there are a load of new beasts on the block some real bad a$$ films. The Armageddon’s I call them, “The Core” “The Day After Tomorrow” “Flight of the Phoenix” and the remixing of the “Star Wars” trilogy, any one of these films called have taken out the mains left & right loudspeakers. By that I mean there dynamics are huge between 20Hz & 40Hz damage goods and not having something like multi-spectrum analyzers so that you can keep an eye on the dynamics, therefore saving the loudspeakers from utter doom. Reading back a little bit more on your post, smells like the LFE was sent to the mains, and with no way to limit the LFE with what I have on my Kenwood KRF-X9050D THX select Dolby DTS, AVR you can say good sweet night to the mains, but I run the LFE to a professional THX cinema sub like the JBL 4645 with a newer 18in driver with edge ribbon surround, and for 7 years no problems. And for the fronts three-screen JBL control 5 the back side surrounds JBL control 5 for the middle side surrounds Eltax HT-2Biopolra and for the centre back surround JBL HT-1F, all these are played to near 105dbc weighting each but that depends on the film mixes dynamics. All I can say is use matching loudspeakers for the front, and dumb the use of the internal amplification, use the pre-outputs with matching amplifiers EQ’s etc, etc, etc no worries then, as I can’t run my JBL control 5 on the Kenwood due to the impedance rating, the JBL control 5 are 4ohm load and any film with mad bass range from 20Hz to 40Hz will shutdown the AVR, it’s a safety factor built-in to it, what surprises me is that the Denon didn’t do the same thing and saved the loudspeakers from “Armageddon.”  |  IP: Logged
