Question 1

My subwoofer seems to kick on and produce a low hum when I turn on the coffee pot or microwave even when on standby. Will this product eliminate it?

Accepted Answer

It worth a shot since this product should isolate your sub from any electrical interference.

Question 2

Wow I can't believe this is made in USA!!! My question is what else makes it different from other units for $10? I see no gold plate, etc. Thanks!

Accepted Answer

I haven't ever seen one of the $10 units you mention so can't say specifically how it may differ from another unit, but our supplier who manufactures these in California (Energy Transformation Systems) is known for high-quality audio and video transformers and the frequency response on this is nice and level.  We don't use gold plate on the jacks as ETS doesn't generally use gold and there really is not, contrary to common perception, a performance advantage in it.  Plating on connectors is generally chosen for durability (important) and conductivity (less important) -- you want it to endure multiple insertions and removals.  Nickel plating, as is used here, is very hard and durable.  The "advantage" of gold, so far as it goes, is that gold is more conductive -- but the plating thickness on a connector is millionths of an inch, and so the difference in contact resistance between a higher-conductivity metal and a lower-conductivity metal is minuscule and meaningless, especially in a high-impedance circuit like line-level audio where considerations like capacitance and shield effectiveness are much more important than resistance.

Question 3

I have a fusion (marine stereo) and fusion sub-woofer.  connect via rca cables left and right.  where/how do i install this?  do i for each rca?

Accepted Answer

Yes, unfortunately, you probably need to do two, one for each RCA connection.

Question 4

What is the frequency response for this. Will it pass audio without distortion at 1hz? Most are 20hz and I need lower.

Accepted Answer

Ask BJ or Calrad about its bandwidth; I am sure it does not highpass at 20Hz or close to it, and probably much much lower than that is its rolloff. Its response at 1Hz, who knows? (You do not want or need that in any case.) It will not pass dc, by definition, and for sure you would not want it to. (Can't tell if you understand VLF and perception thereof correctly.)
