Please Help - New Sony STR-DN1080 won't use my Sub

1,244 613 November 24, 2017 at 06:32 PM
Hey guys,
I just bought a new Sony STR-DN1080. I have set it up to replace my old Yamaha.
However my sub is not working. I have the SP set to 5.1 and have gone through the calibration multiple times, but the sub doesn't create any sound. My speaker/sub are Klipsch.
I borrowed a second sub to see if my sub was the issue and the borrowed one is doing the same thing.

Both subs have two inputs and the receiver has two sub outputs. My yamaha had the same thing. I have a cable that splits so you can plug it into both inputs on the back of the sub. Looking at the manual I am using the output on the receiver that is closest to the speaker connector ports. If this wrong, no worries, I also tested plugging into each input alone.

When my sub is plugged in and I run the calibration, I faintly hear some pattern coming from the sub, so I know its trying to receive a signal. But It won't get louder. And the smaller sub that I borrowed, I don't hear anything at all. When I go to the "Test Tone" section I don't hear anything from either sub.

Sony guides and troubleshooting hasn't helped much. They basically tell me to change the speaker pattern or run the calibration tool.

Any suggestions? There has to be a setting somewhere.

Thanks.

Things I have tested:
- change the level of DBs of the subs - nothing
- changed the speaker config to something other than 5.1 and back again
- Changed to small speakers in size
- reset the receiver holding the power button
- Crossover frequency was at 120 for the speakers and changed it to 80 at the suggestion of someone. However, the sub didn't have an option so I am not sure how that would have helped. They are back to 120.

Thanks again.

Check and see if the sub is on, specifically not set to auto. Frequently they don't get enough signal to turn on automatically.

What program are you using to look at your settings? Realteck Audio Manger, or ? This is computer based and goes thru a program for settings, right?

Program?

This is a TV AV receiver. So the settings were viewed through the internal settings of the receiver's home screen.

Ok, soorrry -- I'm computer based surround and not home TV AV. I did find when I had issues with mine that I had to not check all the components in the settings -- check off subwoofer, but nothing else in the first section and then only left and right full range in the speaker section as well as surround speakers

Figured out the problem. The issue was with the sub. IT passed the buzz test and the lights came on, so it must be internal to the sub.
Oh well, I upgraded.....2" bigger sub! Whoo hoo!!
