PCM-KW-672 · STEREO MINI AUDIO INTERCONNECT
RJ45 Male to 3.5mm TRS Stereo Audio Cable
PCM-KW-672 is a 6ft professional audio interconnect that converts a compatible RJ45 studio audio interface to a single 3.5mm TRS stereo male connection. Left and right analog audio channels are combined into the conventional three-contact mini-jack format for direct connection to compatible recording, playback, monitoring and AV equipment.

STEREO AUDIO ON ONE MINI PLUG
Connect RJ45 Broadcast Audio Directly to 3.5mm Equipment
PCM-KW-672 provides a direct cable connection between compatible RJ45-based studio infrastructure and equipment using a conventional 3.5mm stereo audio interface.
Instead of terminating the two audio channels on separate connectors, the cable carries both channels to one 3.5mm TRS plug, making it suitable for devices designed around a standard stereo mini-jack connection.
UNBALANCED STEREO CONFIGURATION
Left + Right + Common Return
The 3.5mm TRS connector uses one contact for each audio channel and a common return connection. This is different from the dual-TRS balanced cables in which each TRS connector carries one independent balanced channel.
STANDARD 3.5MM AUDIO INTERFACE
One Connector for Two-Channel Stereo Audio
The equipment side uses a nickel-plated 3.5mm TRS male connector, providing a familiar interface for compatible recorders, computers, playback devices, monitoring equipment and compact professional audio hardware.
Using a single mini connector keeps the destination-side connection simple where the equipment does not require separate left and right balanced audio inputs.

A Full-Length Cable Rather Than a Short Adapter
The 1.83-meter design allows the cable to run directly from a compatible RJ45-equipped console, node or studio connection to nearby audio equipment. No separate RJ45 patch cable is required when the available routing distance fits the installation.

CONNECT CONSUMER-STYLE AUDIO TO STUDIO INFRASTRUCTURE
Useful for Recorders, Computers and Playback Equipment
Not every device in a broadcast or production environment uses XLR or 1/4-inch professional connectors. Computers, portable recorders, media players and other compact equipment commonly rely on a 3.5mm stereo interface.
PCM-KW-672 provides a simple way to integrate compatible mini-jack equipment into structured RJ45 studio audio wiring without adding multiple conversion adapters.
Typical Applications
PCM-KW-672 WIRING
Stereo Pin Assignment
| 3.5mm TRS | RJ45 Assignment | Audio Function |
| Contact 1 | RJ45 Pin 1 | Audio Channel |
| Contact 2 | RJ45 Pin 3 | Audio Channel |
| Sleeve / Shell | RJ45 Pins 2 + 6 + Shell / Braid | Common Return / Shield |
Verify the connected equipment pinout before installation. This RJ45 connector is used for audio wiring and should not be treated as a conventional Ethernet connection.

Single Stereo Mini vs. Dual Balanced Mini
A single 3.5mm TRS stereo cable such as PCM-KW-672 carries left and right audio channels on one unbalanced mini connector. This is electrically different from RJ45-to-dual-3.5mm assemblies in which each TRS connector carries one separate balanced audio channel. Select the cable according to the destination equipment interface and required audio format.
