Should i use volume limiter, line out level vrms or pre-gain?

[Dangogh]

I saw a thread says that 2vrms is better for wiim pro plus, so should i adjust in the volume limiter or pre gain? Also how does the limiter and pre gain affect the quality?

This depends on what input and output you use.

The voltage settings is for the analog output only (after DAC).

The pre-gains are digital and before EQ.

Volume limitation is a upper digital volume level.

If any of those are set too high, it may cause distortion. Else they don't cause any sound quality issues.

And while some have asked if a higher output voltage was always better I can't remember anybody giving a positive answer. Even if someone said so, I disagree.

The (max.) output voltage should match the input sensitivity of the power amplifier or active speaker. If it's too high you risk distortion overdriving the input. If it's too low you cannot make use of the full power and risk additional noise.

match the input sensitivity of the power amplifier

Interesting. I have my WiiM Pro Plus set to 2Vrms and it seems to work fine. Best I can tell from the specs of the Fosi amp is that input sensitivity is 280mV. Do I have my settings wrong?

As long as you play on low volume it doesn't matter.

It is however best to align the output voltage to the amplifier and then turn up the volume settings on the WiiM. A high volume (60-80) makes a better dynamic range.

So what would that be for 280mV?

I would try 200 mVrms. If you think it's to low then 500 mVrms.
