Does exactly what it claims to do
on 20 August 2010
Bought one of these about a year ago when I was suffering from noise and hum problems in my iMac/USB audio setup. There was a ground loop from my USB audio equipment, and some noise/interference from power-supplies, driving me mad after shelling out some serious dough on audio gear and a new mac. I was at a loss as to how to fix it, until I discovered this neat little gadget.
I have to admit I was skeptical when I ordered it... but...
I plugged it in, and.... nothing. :) No noise. No hum.
This no-nonsense little grey box *completely* eliminated my hum problems, and the background noise level from my Synth equipment dropped so low it only shows up if I push my input amp way beyond normal recording levels, whereas before I had to use a gate filter to eliminate the noise from some recordings.
Regarding quality of the box -- it's a simple folded sheet-metal box, screwed together. It looks pretty robust, and the sockets are perfectly fine. No unnecessary lights, switches, or extra power supplies -- it just sits there silently doing its job.
My only complaint is that the price of these things seems to have risen substantially over the last couple of years... but if you've got problems like I had you probably won't mind shelling out a few tenners to fix hum problems in much more expensive audio/computer gear!
