PROEL MRCA20RD - RCA Male Aerial Connector in Nickel-Plated Brass with Flexible Spring and Red Ring
The Proel MRCA20RD is a professional-grade male RCA aerial connector designed to provide a secure, stable, and durable audio connection. Manufactured to Proel's engineering standards, this component is essential for sound technicians, installers, and audiophiles who need to repair or build their own interconnect cables with a superior quality guarantee compared to standard plastic connectors.
This model stands out for its robust nickel-plated brass construction, a material that not only provides excellent mechanical protection against bumps and drops, but also acts as an effective shield against electromagnetic interference. Its design incorporates a crucial element for cable longevity: a flexible cable guide spring on the back. This spring relieves mechanical stress at the soldering point, preventing the cable from bending excessively or breaking right at the connector exit—one of the most common failures in audio equipment.
The MRCA20RD is optimized to work with cables up to 6.2 mm in diameter , making it compatible with the vast majority of unbalanced instrument and line cables on the market. Furthermore, its distinctive red ring allows for quick and unambiguous visual identification of the right channel in stereo setups, facilitating connections in low-light environments or at the back of racks and amplifiers.
Main features
-
Integral metal construction: Body made of brass with a nickel-plated finish that ensures corrosion resistance and extreme durability.
-
Pull protection: Includes a high-strength flexible helical spring that protects the integrity of the cable and internal welds.
-
Clear identification: Red color coding ring, ideal for marking the right channel (R) or specific signals on patchbays.
-
Cable compatibility: Supports coaxial or shielded audio cables with an outer diameter of up to 6.2 mm.
-
Solder assembly: Internal terminals designed for clean and firm soldering, ensuring noise-free signal transmission.
Benefits for the user
Choosing the Proel MRCA20RD connector means investing in the reliability of your audio chain. Unlike inexpensive molded connectors, this connector can be reused and repaired if needed. Its metal housing provides superior shielding, minimizing the introduction of hum or other unwanted noise into the signal—critical in studio or live environments.
The addition of a strain relief spring significantly extends the lifespan of the pre-assembled cable, resulting in long-term savings by reducing the frequency of repairs or cable replacements. Its ergonomic design makes it easy to grip for smooth connection and disconnection without straining equipment.
Use cases
-
Custom cable making: Ideal for creating custom length RCA cables for Hi-Fi, Home Cinema or recording studios.
-
DJ equipment repair: Perfect for replacing damaged RCA connectors on turntables or mixer outputs.
-
Fixed installations: Use in auditoriums, conference rooms or domestic installations where a robust and permanent connection is required.
-
Car audio systems: Their metal construction withstands the vibrations typical of car audio well.
Frequently Asked Questions
What is the maximum cable diameter this connector supports?
The connector is designed to accommodate cables with an outer diameter of up to 6.2 mm, which covers most standard microphone and line cables.
Is soldering required to install this connector?
Yes, the Proel MRCA20RD is an aerial mount connector that requires tin soldering to secure the center conductor and shield to the internal terminals.
Can the spring be removed?
The spring is an integral part of the strain relief system, although in some specific assemblies it may be removed, it is strongly recommended to keep it to ensure the durability of the cable.
What is the red ring used for?
The red ring follows the international standard color code for identifying the right channel in stereo signals. The model with a black or white ring is typically used for the left channel.
