What Is an RJ45-to-Dual-TRS Audio Cable?
An RJ45-to-dual-TRS audio cable is a: Passive Audio Breakout Cable
It distributes multiple conductors from a compatible RJ45 audio interface to two independent TRS plugs according to a defined pin assignment.
Its basic operating principle can be represented as:
RJ45 Audio Port → Defined Pin Mapping → Two Audio Branches → TRS P1 + TRS P2
It primarily addresses the following requirements:
Different connector formats;
Limited equipment interface space;
The need to split professional audio lines;
Quick wiring inside equipment racks.
PCM-KW-667 →What Is a 6.35mm TRS Connector ?
The 6.3mm TRS connector, also known as a 1/4-inch TRS, consists of three separate conductive sections: Tip, Ring, and Sleeve. It is widely used in professional mixing consoles, audio interfaces, effects processors, monitoring equipment, broadcast systems, and patching installations.
TRS defines the physical contact structure rather than a fixed signal function. It may carry balanced audio, stereo audio, or other signals, so the actual pin assignment and electrical configuration must be verified against the equipment specifications.
Pain Points
Core Product Value
PCM-KW-667
◆ Why Use a 200mm Short Adapter?
PCM-KW-667 features a compact 200±10mm cable length, making it suitable for short-distance connections around rack equipment, console rear panels, audio nodes, patch bays, and control rooms. The short cable reduces excess cable accumulation, desktop clutter, and unnecessary routing inside equipment racks.
It also minimizes the need for additional fixing points, supporting cleaner installations, easier connector identification, convenient maintenance, and more efficient space management in high-density professional audio systems.
◆ Does Shielding Eliminate Noise?
No. Braided shielding helps reduce external electromagnetic interference, but it cannot guarantee a completely noise-free audio system. Actual noise performance also depends on equipment grounding, balanced or unbalanced audio topology, pin assignment, ground loops, cable length, power supply quality, and input/output circuitry. Proper shield termination, sensible cable routing, and equipment compatibility are equally important.
Noise performance should therefore be evaluated across the complete audio signal chain rather than judged solely by the presence of shielding.

Compatibility Statement
Compatibility Verification
PCM-KW-667 features an RJ45 8P8C female connector, but it is not a conventional Ethernet adapter and does not provide universal audio compatibility. Different manufacturers may use different RJ45 audio pin assignments, even when the connector appearance is identical.
Signal formats, audio levels, and input/output roles may also vary. Before installation, verify the equipment model, RJ45 pin assignment, balanced or unbalanced topology, input/output direction, signal level, and TRS wiring to prevent incorrect connections, signal loss, distortion, or potential equipment damage.
Technical Compatibility Notice
Tip, Ring, and Sleeve describe the three physical contacts of a 6.3mm TRS connector; they do not automatically define stereo audio or a fixed audio protocol. Depending on the equipment, TRS may carry balanced mono, unbalanced stereo, insert send/return, or proprietary signals.
PCM-KW-667 is a passive audio breakout cable without an ADC, DAC, audio codec, amplifier, transformer, or network conversion circuitry. It does not perform signal conversion, gain amplification, or active impedance matching. Its actual function must be confirmed against the equipment pinout and electrical specifications.
TRS ≠ Automatically Stereo
RJ45 ≠ Automatically Ethernet
How to Choose the Correct Audio Adapter ?
Verify the RJ45 Audio Pinout
Always verify the exact RJ45 audio pin assignment because different equipment may use different channel and signal mappings.
Confirm Balanced or Stereo TRS
Confirm whether the TRS connection is balanced mono, unbalanced stereo or another equipment-specific format.
Verify I/O Direction and Signal Level
Verify input/output direction and signal level because the passive cable performs no amplification or level conversion.
Match Cable Length to Installation
Use the 200mm version for equipment-side breakout applications and longer shielded assemblies for extended cable runs.

Conclusion：
PCM-KW-667 is a compact professional RJ45-to-dual-TRS audio breakout adapter designed for compatible broadcast, studio and AV systems.
Its value lies in routing defined audio signals from an 8P8C interface into two separate 6.35mm TRS connections while providing shielding, channel identification and compact rack-side installation.
Compatibility must always be verified from the actual equipment pinout and signal format.
Product FAQ
Does TRS Always Mean Stereo ?
No. TRS can carry balanced mono, unbalanced stereo or other equipment-specific signals depending on the wiring.
What Is Balanced Audio ?
Balanced audio uses two complementary signal conductors and a shield/reference path to improve immunity to common-mode noise.
Balanced Mono vs Stereo
A balanced TRS connector usually carries one differential audio channel, while an unbalanced stereo TRS connector can carry left and right channels.
Is PCM-KW-667 a Headphone Splitter ?
No. It should be treated as an equipment-specific audio breakout cable rather than a conventional headphone splitter.
What Is an Audio Breakout Cable ?
A breakout cable separates multiple signals from one multi-contact connector into individual equipment connectors.
