The audiophile RFi kit is specifically designed to suppress audio interference triggered by Radio Frequency Interference problems experienced in typical audiophile systems using a tuner/preamp/receiver, turn table, CD player and speaker system. The ferrite filters are selected to eliminate RFI from 1 to 300 MHz. The filters are easy to install, don’t require modification of the protected equipment and work in almost all cases.
What is included in the kit?
The Audiophile RFI kit contains a a 4 ring filters for the AC power cord and 8 snap-on filters (4-1/2" ID, and 4-3/8' ID) for the device interconnect wires as well as the speaker wires.
Also make sure you connect a good RF ground to the transceiver ground post.
Note to Flex Radio users: Use snap on ferrites for firewire cable, speaker cable and mic cable, Ring ferrites for Antenna output and DC power.
For additional RFI suppression, use a feed line choke at the antenna to suppress common current on the coax feed line – see our store for feed line choke alternatives for use at the antenna.
If you use a linear amplifier we have RFI kits for linear amplifiers that help suppress RFI in your shack or in your neighbor’s house.
