Well, first of all, the Bybee filters are always mean to be installed in series, NOT in parallel...i.e. NOT from H to N or (+) to (-) of AC mains. This would throw a breaker

.
Ideally, I recommend installing a pair of Bybee filters at the AC mains, but with only one, there will still be benefit to installing it in the H or (+) AC input to the player. The small units are rated for 4A, so it should be no problem for a player that likely has a 1A fuse.
I hope this helps. If you choose to purchase another small bybee filter, I can supply you with one for $95.
Thanks,
Dan
