PROEL S400 - Professional 6.3mm "Mini Jumbo" Mono Male Jack Connector with spring protection
The PROEL S400 is a professional audio connector designed to exceed the demands of live sound and studio environments. Classified as a "Mini Jumbo" connector, this 6.3 mm (1/4") mono male jack stands out for its ability to accommodate larger gauge cables, offering a robust and reliable solution where standard connectors often fail.
Constructed with a solid nickel-plated brass body, the S400 not only guarantees exceptional durability against bumps and drops, but also offers effective shielding and a professional silver finish. Its design facilitates the installation of high-end custom cables, ensuring clean and stable signal transmission.
What truly sets this model apart is its high-strength , flexible cable puller . This component is vital for preserving the integrity of the wiring, as it absorbs mechanical stress at the most vulnerable point of the connection: the junction between the cable and the connector. Thanks to its generous 9 mm opening, it's the perfect partner for thick speaker cables or high-performance instrument cables.
Main features
-
"Mini Jumbo" design: Slightly oversized body for easier handling and to allow the entry of large diameter cables.
-
Nickel-plated brass construction: Corrosion-resistant and physically wear-resistant metal casing, ideal for intensive use.
-
Pull protection: Incorporates a flexible steel spring at the rear that prevents the cable from bending excessively or breaking right at the connector exit.
-
Wide gauge compatibility: Accepts cables with an outer diameter of up to 9 mm , a capacity above the average of standard connectors.
-
Mono TS Connection: Standard 6.3 mm Tip-Sleeve configuration for unbalanced signals.
Benefits for the user
The PROEL S400 eliminates the frustration of working with flimsy connectors that won't close properly when using thicker, higher-quality cables. Its robust construction protects your internal solder joints from accidental tugs on stage, dramatically extending the life of your cables. Furthermore, its nickel-plated finish ensures consistent conductivity and oxidation resistance over time.
Use cases
-
Charging Cables (Speaker): Ideal for making Jack-Jack cables to connect guitar/bass heads to screens, thanks to its capacity for thick section cable.
-
High-End Instruments: Perfect for guitarists and bassists who use "boutique" instrument cables with diameters greater than 7mm.
-
Fixed and Touring Installations: Repair or creation of audio hoses that require connectors that can withstand the daily abuse of assembly and disassembly.
Frequently Asked Questions
Does it work for stereo cables?
No, this is a mono connector (TS - Tip/Sleeve). If you need a stereo or balanced connection, you should look for the TRS (stereo) version.
What is the maximum cable diameter it supports?
The spring and housing are designed to accommodate cables up to 9 mm in outer diameter, making it very versatile for thick cables.
Is it difficult to weld?
Being a "Mini Jumbo" connector, it offers a reasonable interior space that facilitates soldering the conductors, even for those with average experience in electronics.
