Max2 Posted January 30, 2015 Share Posted January 30, 2015 A few months back I remodeled my "above garage room". New flooring, paint, acoustical panels, can lights, etc. Since then something sounded a little bit mono and kind of thin, but I had made so many changes in my room in a short period I let it go. Well , last night I pulled both of my mains out and sure enough, I had the main speaker input wire out of phase on the left side. How in the world do I go red/negative and black/positive? Maybe because the lighting is so bad up there even though I added 4 can lights? Anyway, I was elated and had a little celebration all by myself right then. I swapped the wires, sat down and immediately the left+right speakers meshed so much better. I popped in in DVDA and ran about 10 watts through them even though the baby was asleep at the other end of the house, yeah I was that happy. I haven't had in phase stereo in months, but the weekend is going to start out much better knowing what I was missing was replenished with the easy swap of two wires. 3 Quote Link to comment Share on other sites More sharing options...
The Dude Posted January 30, 2015 Share Posted January 30, 2015 DVDA Whenever someone post about dvda, I think of something else. Anyways those little things are the ones that make you scratch your head. Your mad that you didn't catch it sooner, but happy its something so simple. I thought my left speaker output went out on my receiver. I was telling my buddy about it at work, he reminds me of the little ones at home who are learning to walk and grabbing everything in sight. Especially knobs, soon as I was home I checked the balance knob and sure enough it was turned to the opposite side. What do you know something simple, woo hoo. 2 Quote Link to comment Share on other sites More sharing options...
Max2 Posted January 30, 2015 Author Share Posted January 30, 2015 You're right Duder. I think the majority I have learned in life has come from complicated and simple mistakes, but it sure is nice once in while correcting a mistake so quickly and easily with 100% reversal and no blood to wipe up, bandaids to break out or a hijacking of the wallet. 2 Quote Link to comment Share on other sites More sharing options...

billybob Posted January 30, 2015 Share Posted January 30, 2015 Listened to a Carver 250 watt amp setup for a couple of days before realizing the mono switch was set on the rear. 1 Quote Link to comment Share on other sites More sharing options...
Thaddeus Smith Posted January 30, 2015 Share Posted January 30, 2015 sheffield labs' "my disc" is the first thing I always play after any system change (especially ones that involve interconnects and speaker wires) to test for proper channel connections and phase. 2 Quote Link to comment Share on other sites More sharing options...

Oh yeah, bass straightened out and it seemed to lose a midrange kind of warble or thin sound. 1 Quote Link to comment Share on other sites More sharing options...

That's pretty cool and I could use one of those. Audyssey said that my left front and left rear were both out of phase, but I have seen that before and both turn out not to be. I just let it go. As many times as I have setup Audyssey only to get crappy sound with music I have given up. After the big rug and padding I put down in the room along with 100 sq feet of Acoustic panels I thought maybe Audyssey will throw me a good card this round correcting all the reverb, echos, etc.....Nada. Audyssey still covers up or masks music content with the boosts and cuts. It may make up with a boost here or there, but it seems to cover up delicate features of the song or color it in a way where it just sounds compressed or distorted. Resolution is tossed out the window. I hear a lot of people that have great luck with AudysseyXT 32 versions with music, but my setup seems to morph the original into something that not only its not, but do it in a way that it just sounds like crap. Im wondering if I have a bad mic, but I have used the Audyssey mic with REW and it seems to be ok and doesn't show any crazy readings. Im just sticking with a direct source. 1 Quote Link to comment Share on other sites More sharing options...
Moderators dtel Posted January 30, 2015 Moderators Share Posted January 30, 2015 These things happen, we once watched 30 minutes of a movie not realizing the button to turn off mains was pressed. Glad you found the problem and Congratulations on the new room. 2 Quote Link to comment Share on other sites More sharing options...

angusruler Posted January 30, 2015 Share Posted January 30, 2015 just recently plugged my front channel cornwalls into the wrong spkr inputs on my receiver......DUH! and I was wondering why there was no sound! love to blame it on the lighting, but, my eyes are getting BAD! 2 Quote Link to comment Share on other sites More sharing options...
wvu80 Posted January 30, 2015 Share Posted January 30, 2015 (edited) You crossed your pos and neg? Geez, that IS boneheaded. I'm sure nobody else here has ever done that.

richieb Posted February 2, 2015 Share Posted February 2, 2015 Yep been there too, matter of fact just last week. Found that when we wired the networks to the tweeters in my new KHorns the right side tweet was wired out of phase. Had some friends over for a listen and a golden eared veteran with years of critical listening experience was certain something didn't sound right. "Something's out of phase or the room is causing an imbalance". We look at each other, and with my three decades of hifi heard nothing, neither did another. So now I'm concerned something is wrong with my cherished KHorns so the next day I pull 'em out the corner and there it is, cross wired at the network input. Big relief, all was put right and yep they certainly sound much more coherent. Embarrassed I didn't pick it out, for several days none the less. So I used the opportunity to replace older cable with better and pipe insulation seal to the corners. All is good but a dinged ego. Quote Link to comment Share on other sites More sharing options...

Paducah Home Theater Posted February 2, 2015 Share Posted February 2, 2015 If it makes you feel better, recently after rearranging some stuff I had a full range signal going to one of my subwoofers. I had one sub output going to one side of my sub amp, but the other side of the amp was getting a full range signal. I don't have a crossover set up on the amp either. I had voices and guitars and all kinds of stuff coming through half my subs, with me wondering why things sounded weird. The RCA output for the subs was in a row of other RCA outputs and I was one off. 1 Quote Link to comment Share on other sites More sharing options...
