This has been specifically designed for enhancing the contact characteristics of RCA (phono in the U.K.) plugs and similar, such as XLR plugs.
This conditioner improves all electrical contact surfaces by application of a trace amount which is burnished into the surface with a soft cloth. Then, a second trace amount is applied and rubbed into the metal to fill microscopic irregularities. This creates a smoother surface for improved signal transfer at the contact interface.It is best to apply to the socket into which the RCA (phono) plug will be inserted.
It only a small amount is needed to enhance the performance of a connection. To maintain that performance, re-apply every thirty to sixty days.
Caution: Cardas Contact Conditioner was not intended for use on Cardas (6.35mm) 1/4" and (3.175mm) 1/8" (jack) Phono Plugs or on Cardas Power Cords because it is highly conductive and may compromise the dielectric properties of the connectors.
