Dimmer Buzzing - Noise Reduction

Hi, does anyone know of any way to reduce the buzzing sound coming out of a 12-Ch dimmer?

 

1. Put it in a sound proof enclosure... (just had to say it )

2. Usually due to low voltage downlight transformers not suitable with c-bus.

There are a few threads on the forum regarding this, use the search function... like this
