PCM-KW-669 combines one RJ45 8P8C female audio interface with two independent 3.5mm TRS male branches in a compact 20cm assembly. The short cable length is especially useful for broadcast consoles, desktop monitoring devices, compact audio interfaces, and short equipment-to-equipment connections inside racks.
Compared with combining long patch cables and multiple adapters, this integrated RJ45 to dual 3.5mm TRS audio cable reduces excess cable around closely positioned devices and provides a clearer physical breakout path for corresponding audio channels.
The short 20cm cable path minimizes unnecessary analog cable length between adjacent devices. When matched with the correct equipment pinout and wiring configuration, it helps reduce cable clutter, excess resistance, and potential interference associated with unnecessarily long interconnects.
The RJ45 side provides a centralized equipment connection while the two 3.5mm TRS branches route the corresponding audio channels to downstream devices, making the AXIA audio breakout cable practical for monitoring, testing, recording, and control-room auxiliary audio paths.

Product Features
Standard Dual-Channel Splitting
Precisely splits a single network signal into two independent 3.5mm TRS stereo connectors.
Compact Space Optimization
The 20cm short cable design eliminates rack clutter and reduces impedance loss.
Fully Shielded Anti-Interference Structure
High-density braided shielding effectively blocks studio high-frequency EMI and RFI noise.
High-Precision Female Socket
The RJ45 8P8C female receptacle features a reinforced clip design for secure frequent hot-plugging.
Core Application Scenarios
AXIA Livewire Network Breakout
Designed for audio breakout within AXIA Livewire broadcast networks, this cable routes compatible RJ45 audio interfaces to dual 3.5mm TRS connections for analog monitors, portable recorders, and test equipment. Its compact 20cm length is ideal for short links between consoles, Nodes, and monitoring devices, helping reduce cable clutter while providing clear and convenient dual-channel audio routing.


Digital Radio Control Rooms
Suitable for digital radio control rooms, studios, and engineering test areas, this cable provides flexible connectivity between broadcast consoles, AXIA audio Nodes, portable audio testers, headphone distribution amplifiers, and compact monitoring devices. The RJ45-to-dual-3.5mm TRS design supports both temporary signal testing and permanent auxiliary monitoring links, while the short 20cm length is well suited to closely spaced desktop and rack-mounted equipment.
Core Performance Advantages
● High AoIP Ecosystem Compatibility
Natively matches the impedance and pinout requirements of mainstream protocols like AXIA Livewire.
● Zero-Latency Linear Transmission
Pure copper conductors deliver lossless transmission, ensuring absolute sync for live broadcast signals.
● Ultra-Low THD
Professional acoustic tuning maintains exceptional sound fidelity even during high-dynamic signal transmission.
● Industrial-Grade Balance Rejection
Excellent Common Mode Rejection Ratio (CMRR) provides pure audio quality at the end of long AoIP runs.

Frequently Asked Questions
Q1: Can this cable be used for ordinary Ethernet network data transmission?
A1: No. This cable is a broadcast audio breakout cable; although it uses an RJ45 8P8Cconnector, its internal wiring is specifically designed for AXIA cables and audio signals, intendedsolely for stereo audio transmission and cannot transmit LAN or Internet data.
Q2: Why choose 20cm length? What is its help for sound quality?
A2 : 20cm is a compact audio cable length designed for racks. Excessively long cables in the cabinet will become"antennas" to absorb electromagnetic interference. The short line design not only makes the room more dean, but alsominimizes signal attenuation and achieves the high performance of the Lovw noise audio cable.
Q3: How do I connect this cable to my AXIA Livewire system?
A3: You simply need to plug the R4S female connector of the R4S to 3.5mm audio adapter (RJ4S to 3.5mm audioadapter) into a standard network patch cable from an AXIA node, and then connect the other two 3.5mm TRS maleconnectors to your stereo playback, recording or monitoring devices for instant plug-and-play distribution.
