onkyo 606 and polk rm6880 question

off1c3r

Hey

I posted this on another forum, but I am having some issues with my setup. I just got the Onkyo 606 with the polk rm6880 which I love.

Here is the exact post pasted:

"To sum it up, i have the front L / R and center speakers connected right now and sound is great but from the subwoofer out into the sub its just super low. I turn the gain up on the reciever and on the sub but its still super low. A guy from polk said to test the sub by putting the rca inputs into my bluray and feed the audio to the sub and yeah at 1% volume its loud, and bassy. For every other setup i try with the receiver its just super low. Even when i wired the recievers front R/L to the sub, and then had the output from the sub go to the front R/L .. still the same. The only way i have been able to get any kinda real response is from turning the sub gain 75%, raising the gain on the EQ +8 for sub, and raising the volume to like 30+ which is getting loud for me. I was going to try lowering the front/center gains on the reciever to like -db's and keep the sub 0? (to raise the overall volume higher to get sound but leaving the sub the same) I don't know if that would help though."

Thats pretty much it. I don't know if anyone else had this issue?

off1c3r not familiar with the 606 but there are a number of members here that probably will be more help but I'll give it a shot. The test that the Polk rep. had you try would indicate the sub driver and amp are working. So some of my first thoughts are something in the AVR set up. What is the source you are sending to the 606? Do I understand correctly, that you are using a line level input to the sub R/L RCA or LFE input? Set up should be something like Sub ON, F and center SMALL, cross over around 100hz. There also could be a setting to send all lower freq. to the sub not just LFE content (not sure on this). Did you run auto cal.? What did that set things at? If you send manual test tones out do you hear any thing from the sub? It could be a cable problem but if I understood correctly you have tried line level and speaker lever inputs which should rule that out. This should have also ruled out any problem with the sub out on the AVR.

Hope some one with the 606 can give you more help. Good Luck and welcome to club Polk.

I have an Onkyo 606 and had RM6880 speakers and sub hooked up to it. I hooked the sub up with an RCA jack from the sub out on the Onk to the left channel of the sub, set the sub at about 50% volume, and ran audessy. The results were very good, with plenty of bass.

Thank you for the replies...

I kept thinking it was something in the AV setup too but i can't figure out what it is. Yes i am using the sub preout line level with a coaxial cable (tried 2 different ones) into a Y adapter monster cable (tested it with Rca cables and bluray player and was no issue) and that goes into the sub. The LFE setting is on with the reciever, and the cross over is 100. The Fronts is set to full band, i didnt see a large/small option. When i do the gain test, i hear the swooooshhhhh noise from my Front L, center, front R, but then with sub nothing or its VERY VERY low. I connected the amp via speaker level input to sub, and same outcome. If its the same outcome with the speaker level inputs, what does that mean? I used speaker level from reciever to sub, then sub to fronts. the fronts had full range sound and were fine but sub had next to nothing.

I didn't run audessy.. not sure how to actually didnt read the manual 100%. Did plug and play sound like how i described? Did that happen to you? Again the only time i ever got some powerful output was when i connected the bluray player directly to the sub rca and i got full range sound, not filtered, but it still was super loud. I will start to read the manual more but from all the settings I messed with.. nothing =(

I reran audessy and it seemed to help a lot. It did however make my speakers -11 and -10 dbs and my sub -9 but i moved the sub back to 0, and I guess because the other speakers negative, it allows me to raise volume more and i guess get more output from it. I changed the -9 to 0, but left the speakers at -11 -10 and stuff, and then I raised the sub eQ to like +6 and it seems to be good right now. The subs gain setting is like 45%.

I don't have my surrounds setup yet, so i am a little nervous about redoing the audsessy setup since it definantly did something in a setting that i couldn't see to raise my subwoofer output. I would hate to rerun it and then it changes the output again and makes everything back to how it was heh.. but still this is very weird what happened and i never heard of other people having this issue. I still need to tweak the whole setup more though but at least I am going in the right direction

I'm following this post as you described the same problem I am experiencing with my 606 and a psw505. I have the fronts set to crossover at 100, sub on, and am using the lineout from the Onkyo to the unfiltered sub input. The auto set-up finds the sub, but playing movies in dolby d produces no sound from the sub(?)

Well, After double-checking all connections everything appeared correct. Upon watching the power lights on the back, I saw where it was not recognizing a signal from the receiver and powering up while in "auto" mode. Upon manually turning on the sub-woofer, it works perfectly! Tons of sound!!
