I also had an UPS near my gear Rack and the A2D hummed like crazy! I Had to move the UPS to another room. It was both channels however, it's strange that on yours only one channel is affected.
Conclusion is keep your UPS / Power conditioners / anything with transformers that could create a strong electrical field away from APIs
