The STS-RF1 is an aluminum chassis for mounting one STICK-ON module. The chassis provides shielding to suppress radio frequency interference. External audio, power supply or control signals are each connected to the STICK-ON module through a specialized radio frequency suppression filter. External wiring connects to a detachable terminal block. Cable shields are connected to a large grounding screw above the terminal block. The cover is equipped with tabs to securely mount the chassis to any flat surface.
The STS-RF1 is recommended for use in installations where excessive rf interference levels are anticipated from sources such as WIFI transmitters.
