Power Conditioner for Sub - Blu-ray Forum

-DLS- · 01-28-2009, 11:39 PM

I read this on a review for an APC H15 Power Conditioner.

"The only issue I had with the H15 was its interaction with a subwoofer. Some amps are designed such that they will fool the H15 into thinking that it is in a low voltage situation. The H15 will naturally boost the voltage to accommodate. This can blow the fuses on the sub amps which have very tight operational tolerances (provided they have them). I had this happen twice before I discerned it was the H15/sub interaction. From the standpoint of blame - it's hard to find a culprit. The amp is doing what it is supposed to be doing and the H15 is doing its job. My suggestion is to connect the H15 to a subwoofer with caution. Under normal circumstances this shouldn’t be an issue, but if you find a similar experience when you plug your subwoofer into this unit, disconnect it and plug it into a standard surge protector (APC makes plenty of these as well). I would like to note that I had a number of receivers plugged into the H15 without a problem so my issue may be isolated specifically to the subwoofer I was using in this review."

Other power conditioners would maybe act the same way. I plugged my sub to a surge protector by itself. My other stuff will be going into the APC that I just ordered (for a great price - $149 on audioholics.com).
