No subwoofer sound

[pascaldutchy]

I upgraded from a Denon AVR-X2500H to an AVC-X3800h.
speaker setup
front r820f
center r504c
Surround r51m
subwoofer r120sw

Previously I got decent bass from the R120SW.
almost nothing now.

I have my front and center set to 80hz.
Surround at 120hz.
subwoofer connected to LFE.
gain at 40%
crossover on the subwoofer on LFE.

crossover subwoofer via denon at LFE and 120hz.

what am I doing wrong?

Welcome @pascaldutchy

He'll help you sort it...

What are the speaker and sub output levels in the receiver set to?

[pascaldutchy]

I don't quite understand you with output levels.

do you mean dB?

[pascaldutchy]

Front +2 dB

Center +1,5 dB

Rear + 2dB

Subwoofer 0,0 dB.

If i raise the dB for the sub it don't make af difference

Are those results from you setting them or did you run your receiver’s auto setup?  Is anything turned on such as a power saving mode or late night mode?

Sounds like a dead amp.

I first did it with Audyssey. As a result, I discovered that I barely got any sound from the sub.

therefore a factory reset. after this manual setup was done. the test tone made the sub come to life, but after that it was nothing again. so the sub just works. What happens if I plug the plug into subwoofer output 2 and it indicates that I have 2 subwoofers while this is not the case?

I don’t know about the two subwoofer thing but Audyssey generally sets the bass output lower than most people like.  If you lower the dB level to each speaker to -5dB on your receiver but leave the subwoofer dB the same, then what happens?
