Neutrik NA2M-D2B-TX 3-Pin Male XLR to RCA Balancing Audio Transformer

• Solve ground loops, hums, and signal mismatch issues instantly with the professional Neutrik NA2M-D2B-TX 1:1 Miniature Audio Transformer Balancing Adapter.
• Built specifically for broadcast environments, recording studios, live staging, and high-end AV installations, this inline utility component acts as a passive impedance-matching bridge and balancing adapter between consumer unbalanced lines and professional balanced systems.
• The adapter features a premium 3-pin male XLR connector on one end and a female RCA/phono socket on the other, wrapped inside a rugged, black-anodized aluminum extrusion housing that offers tour-grade structural durability.
• Inside, it features a high-performance 1:1 audio transformer with a 200 to 200 impedance ratio.
• This internal transformer physically isolates the input and output stages, effectively blocking common-mode noise, ground loop hums, and radio frequency interference (RFI) without needing an external power source, ground switches, or manual gain adjustments.
• Optimized strictly for line-level signals, the NA2M-D2B-TX accommodates a maximum input level of -3 dBu at 50 Hz with less than 1% Total Harmonic Distortion (THD), maintaining a flat, transparent frequency response across the audible spectrum.
• To eliminate configuration mistakes in complex multi-channel routing layouts, the RCA side features a clear, red color-coded identification ring.

Features

• Passive Signal Balancing: Converts unbalanced consumer RCA line signals to true balanced male XLR lines smoothly without requiring batteries or phantom power.
• Ground Loop Isolation: High-quality internal 1:1 audio transformer breaks physical ground paths to suppress system hums, buzzing, and static.
• Extruded Aluminum Housing: Rugged, black-anodized metal outer shell protects the inner transformer core from heavy crushing forces and drop impacts.
• Red Channel Color Coding: Outfitted with a distinct red visual ring on the RCA entry point for fast, error-free channel pairing in high-density patches.
• Low Distortion Performance: Delivers clean audio transmission tracking up to -3 dBu input levels with nominal harmonic distortion under 1%.
• Secure Latch Lock Support: Standard XLR male design interfaces cleanly with any locking female socket to prevent unexpected cable separation.
