Hello everyone,
after I was able to learn a lot here by reading along, I have bought a home theater system according to my budget, consisting of:
I have the problem that the all the five tweeters of my speakers clearly "scratch" or produce a distorted sound at certain frequencies. This is especially audible at piano.
I have proceeded as follows or have tried the following solutions to the problem:
Then, of course, I first suspected the speakers themselves. Luckily had another amplifier there for testing, namely a SABAJ A4. Was quite baffled when with this amplifier the distortion was no longer present. Same wiring. So now I suspect the Denon AVR.
I have already turned off all software preprocessors like "Restorer".
Unfortunately, I lost the Audyssey calibration microphone, have already ordered a replacement. But even without calibrating, there shouldn't be such serious problems, right?
I can attach the complete configuration of the AVR here, but actually everything is in factory state. Ran through configuration wizard, set front L and front R to "large", levels I left all untouched.
Does anyone here have any other ideas of what I could try? I'd also be happy to make a recording of the distortion/scratching if it's not entirely clear what I mean.
I hope this isn't a hardware fault, as the system is performing great otherwise. It's also not a very audible issue, on most movies and music I don't hear it, just with isolated sounds in certain frequencies like higher piano octaves.
Thanks in advance!
after I was able to learn a lot here by reading along, I have bought a home theater system according to my budget, consisting of:
- Denon AVR-S650H
- Jamo S626 HCS 5.0
I have the problem that the all the five tweeters of my speakers clearly "scratch" or produce a distorted sound at certain frequencies. This is especially audible at piano.
I have proceeded as follows or have tried the following solutions to the problem:
- Changed the cabling: with/without banana plugs, both terminals supplied with separate cables/used a cable with a bridge at the speakers.
- Reset the AVR to factory settings
- AVR manually set to 6 Ohms
- tried different sources: streaming via TIDAL/Spotify, audio via HDMI, audio via optical
