ART DTI Dual Transformer/Isolator

Purchased a few Australian Monitor WPBT-W wall panels, these generated a 125hz buzzing when idle, I tried the ART Cleanbox which reduced it, but the ART DTI worked perfectly in fully removing and resolving this issue.

It works as expected. :)

I purchased this item hoping to address a persistent hum in my system. Unfortunately the result was that the volume of the hum increased substantially. When I contacted Sounds easy using the contact form on web page, to see if I could return the product in its original packaging, there was no response (as of now about a week later). Previously this form had resulted in a quick turnaround.
