PCM-KW-669 · COMPACT BALANCED AUDIO ADAPTER
RJ45 Female to Dual 3.5mm TRS Balanced Audio Adapter
PCM-KW-669 is a short-form professional audio adapter that converts a compatible RJ45 studio audio interface into two separate 3.5mm TRS balanced connections. Its 20cm construction is designed for equipment-side termination where long breakout cables would add unnecessary cable length around consoles, racks and workstations.
STUDIOHUB-STYLE ADAPTER
Two Balanced Mini Connections from One RJ45 Audio Interface
PCM-KW-669 separates the two analog audio channels available on a compatible RJ45 studio interface and presents them on two individual 3.5mm TRS male connectors.
Each mini connector carries its own balanced audio channel. This makes the assembly suitable for professional equipment requiring separate left and right balanced mini connections rather than a conventional stereo AUX connection.
BALANCED AUDIO FORMAT
Two TRS Plugs, Two Independent Audio Channels
The two 3.5mm connectors should not be interpreted as two duplicate stereo outputs. In this wiring configuration, one TRS connector carries one balanced audio channel and the second TRS connector carries the other balanced audio channel.
This product is therefore different from a conventional headphone splitter, AUX Y-cable or dual stereo distribution cable.
COLOR-CODED CONNECTIONS
Identify the Two Audio Channels at a Glance
The two nickel-plated 3.5mm TRS connectors use different molded colors, helping installers distinguish the individual audio branches during installation, testing and maintenance.
The compact mini connector format is useful where equipment panel space is limited while balanced analog audio connections are still required.
Designed to Sit Close to the Equipment
The short adapter format allows the RJ45 infrastructure cable and the equipment-side audio adapter to remain separate. This is useful in structured broadcast installations where different patch-cable lengths may be used while the final equipment adapter remains compact.
EQUIPMENT-SIDE CONNECTION
Compact Adapter for Consoles, Nodes and Studio Racks
PCM-KW-669 is suited to installations where a structured RJ45 audio run terminates close to professional equipment using balanced 3.5mm connections.
Typical applications include broadcast consoles, audio nodes, studio monitoring equipment, recording systems, test equipment, workstation audio and professional AV integration.
