## Questions & Answers

**Q: Could these work for a 3.5mm double coil wire?**
A: These cores come in various sizes, that you need 3.5 mm is accommodated in a 1.5 mm cable at least up to 3.5 mm maximum, and if it does not work, you can use the core of 5 mm, which fits into a 3.5 mm cable at least up to 5 mm and I think that the cable you have should fit well in one of those two cores.

**Q: what frequencies do these absorb**
A: that depends on the length of cable they are being used on.  It's the cables that act as antennas, both radiating and receiving signals.  It may take multiple units on your cables to reduce/eliminate the bothersome signals.

**Q: Will these filter out a radio station leaking into my audio**
A: It depends on the strength and the proximity of the transmitting station.  Under most conditions, you may be able to minimize or eliminate incoming radio frequency interference by clamping these onto your speaker leads.  It may take more than one if the signal is very strong.

**Q: Could these work for a 3.5 mm double coil wire?**
A: Should work fine.
