I dont think you can rewire a 50ASX2 stereo to become a BTL. The BTL module is missing som parts compared to the stereo module, at least there is only one output choke.

What you can do is to feed them balanced signal from you DCX, connect speaker to both "hot" outputs, and hope for the best. It will work, but if its any good I cant tell.

If I recall correctly, the missing components on the BTL module were stripped for cost reasons only. You should be able to use a stereo module for BTL without issues (no guarantees though, my memory may be off )

Small info,
just got replay from ICEpower that stereo version can't be transfer to BTL mode.
Thay say that they are two diferent versions from factory and modification can't be done.

The info come from icepowerinfo (at) bang-olufsen (dot)dk

Default 50asx2

Hello,
I have a ICEpower 50asx2 module, SE edition (2x50W) and I found something interesting concerning the sound. I want to know if this is a problem or a normal behavior?
I connect the IN connector of the module either directly to the laptop output or a audio mixer (Phonic AM220) master output. When I move the balance to L or R, I get more bass on one or the other speaker. If I put the balance to middle position (normal), the sound loose some bass. Is this normal? Do I have to make different connections on input of the module? I think it's a simple analog input with L, R and common ground.

Maybe you have one of the speakers out of phase? That would explain this.

Definately sounds like one speaker is out of phase.
