Description
The MA3MRM is a precision metal adapter connector engineered to bridge 3-pin XLR male and RCA male interfaces, allowing professional audio equipment with different connector standards to be paired quickly and reliably. Built around a rugged zinc die-cast shell, the MA3MRM is designed for long-term durability in demanding professional audio, broadcast, and live-sound environments where consistent signal integrity and mechanical reliability are essential. Its compact form factor (65.20 ± 0.30 mm in length, Ø20.20 ± 0.20 mm) makes it easy to integrate into existing cable runs and rack setups without adding bulk, while gold-plated copper alloy contacts and a secure latch-lock mechanism ensure a stable, low-resistance connection over thousands of mating cycles.
Key Features
- XLR-to-RCA Conversion: Converts a 3-pin XLR male connector to an RCA male connector, enabling seamless interfacing between mismatched professional and consumer audio gear.
- Rugged Zinc Die-Cast Shell: Constructed from durable zinc alloy (ZnAl4Cu1) for a long service life and high mechanical reliability, even under repeated use.
- Secure Latch Lock: Integrated locking device keeps the connection firmly seated, preventing accidental disconnection during use.
- Low Contact Resistance: Contact resistance of ≤6mΩ ensures minimal signal loss and stable performance.
- High Dielectric Strength: Rated at 1.5kVdc, providing reliable insulation and protection against electrical breakdown.
- Extended Mating Life: Rated for more than 1,000 mating cycles, supporting frequent connect/disconnect use in touring or studio applications.
- Compact, Consistent Form Factor: Precisely dimensioned (65.20mm length, Ø20.20mm) for predictable fit within cable assemblies and equipment panels.
Material and Environmental Specifications
