Know before you buy
Rhodium is an exceptionally hard, corrosion-resistant metal that provides a stable, long-lasting contact surface. When plated over silver, it maintains the high conductivity of the silver base while preventing oxidation, ensuring your connection remains pristine over years of use.
Yes, the GRMO is specifically engineered to accommodate substantial audio cables up to 9mm in diameter. This makes it a versatile choice for DIY enthusiasts working with thicker, shielded, or high-gauge cabling.
Non-magnetic materials prevent the introduction of electromagnetic interference and eddy currents that can distort the audio signal. By using eutectic brass, Cardas ensures the connector remains electrically neutral, preserving the purity of your signal path.
The Cardas GRMO male RCA plug is sold individually. This allows you to purchase exactly the number of connectors required for your specific custom installation or cable repair project.
While primarily designed for high-performance analog audio, the high-quality materials and precise construction of the GRMO series make it an excellent candidate for various signal-carrying applications where signal integrity is the priority.
