Hello -

I have an old Atlantic Technology BPM-62 powered sub, being fed by my 1050. Lately, when the entire system is off (with the exception of 1050 standby mode), the sub will randomly crackle and pop. The AC plug of the sub is not grounded, so I plugged into a power strip with ground plug - did not help. I tried swapping interconnect, did not help.

My first thought is that the sub is malfunctioning, but am wondering if perhaps the sub out on the 1050 might be the problem.

Any thoughts or advice are appreciated!!
