Hi, I’m having some trouble with the Wiim Amp Ultra,

If I want a loud sound I have to turn everything to 100, and even though the sound is not that loud… my 20y old denon delivered much louder sound… what am I missing? Thanks

What are you playing? Are you using Replaygain? How loud is loud?
 
Whatever I play. Right now is a vinil record. It’s a 100. I ajusted the pregain to +10db. If it’s a zero it’s REALLY low !
I suggest you start a troubleshooting thread for your specific issue in the appropriate sub-forum. This is not a common issue or a characteristic of the WiiM Amp Ultra.

I am sure the community will be able to help.
 

You should make sure that you have selected the LINE option on your turntable.


Output Level Pre-amp "PHONO": 2.5 mV nominal at 1 kHz, 5 cm/sec Pre-amp "LINE": 150 mV nominal at 1 kHz, 5 cm/sec
Phono Pre-Amp Gain 36 dB nominal, RIAA equalized

Which phono preamp are you using? It is common for vinyl to be quieter than streaming.
The gain of your turntable preamp is 36dB which probably isn't enough for a 2V line input.
I don’t understand… my turntable is very good and it worked perfectly well with my denom with 20y… and it’s a recent turntable, what’s wrong with this setup ?
 
It’s selected like that.
Please confirm that the switch is in the LINE position. It must not be in the PHONO position as shown on the picture.

To which input of your Denon has the turntable been connected? If the amplifier input was labelled PHONO, then the switch is not in the right position for use with the WiiM Amp Ultra.

I think that 36 dB of preamplifier gain should be sufficient to get a usable output from the AT-LP120-USB.

Which model Denon?
Fundamentally, the line level output of the turntable is too low for what the wiim expects as a line in.
Some amps only need a low signal level. The denon probably has an input sensitivity around 200mv whereas the wiim is seemingly much higher.
So "what's wrong" seems to be that these two devices aren't well matched because the phono output is quite weak and the wiim expects something much stronger, like a CD player outputting 2000mv (2v)
 
PS: Whatever you do, switch off all your devices prior to flipping this switch or making or breaking any connections ...

Sorry, my mistake: it’s selected as LINE. As it was with the denon. I’ve tried switching back do PHONO and I can only hear a very very low sound coming out of the speakers.
