Product Features
20cm Anti-Clutter Matrix Cable Body
Precision-engineered 20cm short-run layout tailored to eliminate heavy cable slack and tangles behind busy device patch panels.
Die-Cast 3-Pin XLR Male Connectors
Terminated with dual standard 3-pin XLR male plugs featuring heavy-duty die-cast zinc alloy shells and full-surface gold-plated pins.
Recessed Fully Shielded RJ45 Receptacle
The input features an integrated, high-rigidity metal-shielded 8P8C RJ45 socket designed to deeply envelope and latch incoming patch cords.
Symmetrical Multi-Strand Acoustic Wire Geometry
Internal conductors utilize multi-strand Oxygen-Free Copper tightly twisted in a symmetrical geometry, insulated with low-impedance dielectric layers.
Core Application Scenarios
Professional Studio Installation
Ideal for professional recording studios, audio production rooms, and post-production facilities, connecting monitoring equipment, audio processors, consoles, and other XLR devices. The RJ45 to dual XLR design supports flexible point-to-point transmission of balanced or unbalanced audio signals.

Broadcast Console & Processor Connection
Suitable for point-to-point connections between broadcast consoles, audio processors, signal distribution equipment, and rack-mounted audio modules. The cable converts an RJ45 broadcast interface to dual XLR 3-pin male connectors for convenient audio routing and equipment interconnection.

Core Performance Advantages
Universal Balanced & Unbalanced Matching
Flawlessly adapts to dynamic point-to-point analog routing, delivering advanced capacitive balancing to eliminate amplitude distortion during level conversion.
Cross-Domain Matrix Noise Polarization
Utilizing continuous dense braiding from the network jacket down to the XLR shells, it provides flawless isolation against RFI and ground-loop hums.

Acoustical-Grade Interlocked Zero-Dropout Mating
Combining standard XLR retaining grooves with physical RJ45 clip latches, it maintains an absolute, ohm-stable interface under high-vibration field conditions.
High-Throughput Analog Headroom Performance
The ultra-low impedance internal path ensures that microvolt-level signals and high-level lines retain massive linear headroom during concurrent transmission.
Frequently Asked Questions
Q1: How does this cable simultaneously support both "balanced" and "unbalanced" analog audio point-to-point connections?
A1: Internally, the conductors are fully isolated and mapped according to high-fidelity dual-channel balanced audio topography (Hot+, Cold-, Ground GND). When linked to a balanced layout (such as a standard console or AXIA node), it delivers complete differential noise-canceling routing. For unbalanced integrations, you simply tie the Cold(-) and Ground(GND) legs together at your target outboard gear according to its port specification, ensuring seamless cross-compatibility without a cable swap.
Q2: What is the internal pinout map of this cable? How does it break down the single RJ45 into dual XLR heads?
A2: The assembly follows standard broadcast AoIP physical mapping criteria. The 8 pins (Pins 1-8) inside the RJ45 socket are bifurcated into two separate, electro-acoustically balanced channels routed to the respective XLR male plugs. The Left/Channel A (Hot/Cold/GND) and Right/Channel B (Hot/Cold/GND) legs map fully to XLR Pin 2 (+), Pin 3 (-), and Pin 1 (GND), ensuring polarity perfectly matches the logical layout defined by AXIA, Wheatstone, and other leading manufacturers.
