PROEL MRCA20BK - Professional Male Aerial RCA Connector with Nickel-Plated Brass Body and Flexible Spring
The Proel MRCA20BK is the ultimate solution for sound engineers, professional installers, and audiophiles seeking reliable custom connections. This male RCA aerial connector is designed to exceed conventional durability standards, offering robust construction and superior cable protection. Unlike standard plastic connectors, the MRCA20BK stands out for its nickel-plated brass construction, a material that not only provides exceptional mechanical strength but also offers natural shielding against electromagnetic interference.
One of the critical points in the lifespan of any audio cable is the connection point between the cable and the connector. Proel has solved this problem by integrating a high-quality , flexible cable puller spring on the back. This spring acts as a dynamic strain relief, preventing the cable from bending at sharp angles that could break the inner conductor or damage the shielding. With an opening designed for cables up to 6.2 mm in diameter , it is compatible with the vast majority of instrument, patch, and coaxial cables on the professional market.
Its nickel-plated finish not only gives it a sleek and professional look, but also ensures excellent resistance to corrosion and wear from continuous use. The black identification ring facilitates channel coding (ideally used for the left channel or mono signals) in stereo or multi-channel setups, allowing for quick and clear visual organization on the back of racks and DJ equipment.

Benefits for the user
Choosing the Proel MRCA20BK provides immediate peace of mind in environments where failure is not an option. For the installer, the ease of soldering and precise threaded assembly of the body reduce working time. For the musician or live sound engineer, the protective spring means the cables can withstand tugs, being stepped on, and sudden movements without losing the signal mid-performance. Furthermore, its metal construction offers a solid, professional feel that enhances the perceived quality of any custom cable you build.
Use cases
-
Custom cable manufacturing: Ideal for creating RCA cables of specific lengths for pedalboards, effects racks or home studios.
-
Equipment repair: Perfect for replacing broken plastic RCA connectors on turntables, CD players, or mixing consoles.
-
Fixed installations: Recommended for cabling in bars, auditoriums or conference rooms where a long service life without maintenance is required.
-
Hi-Fi and DJ Systems: Excellent for interconnecting power amplifiers, preamplifiers and mixers with a secure and noise-free connection.
Frequently Asked Questions
-
How is the cable attached to the connector?
The cable is secured by soldering the internal terminals (live and ground) with tin. A basic soldering iron is required for installation.
-
What is the maximum cable diameter it accepts?
The flexible spring has an internal diameter designed for cables up to 6.2 mm. Thicker cables will not pass through the spring.
-
Does it work for video signals?
Yes, being a standard RCA connector, it can be used for composite or component video signals, provided the appropriate 75-ohm coaxial cable is used.
-
Does it come in pairs or individually?
This specific model (MRCA20BK) refers to the single connector with a black ring. For a stereo cable, you will generally need to use the version with a red ring.
Project description
Professional-grade male RCA connector, model MRCA20BK. The connector body is made entirely of brass with a corrosion-resistant nickel-plated finish. It incorporates a flexible metal coil spring strain relief system integrated into the housing, designed to protect cables with a maximum outer diameter of 6.2 mm from excessive bending. The contacts are nickel-plated to ensure electrical continuity. A black color-coding ring is included for channel identification. Conductor assembly and securing are achieved through internal soldering.
