PCM-KW-671 · STEREO MINI AUDIO ADAPTER
RJ45 Female to 3.5mm TRS Male StudioHub Stereo Audio Adapter Cable
PCM-KW-671 provides a compact interface between compatible RJ45 studio audio wiring and equipment using a standard 3.5mm stereo input or output. The 30cm cable combines two analog audio channels into a single TRS mini plug for convenient device-level interconnection.
FROM STUDIO WIRING TO MINI JACK
Connect RJ45 Audio Infrastructure to 3.5mm Equipment
Broadcast and professional audio installations often use RJ45-based structured wiring, while computers, recorders, playback devices and many compact audio products use a conventional 3.5mm stereo connection.
PCM-KW-671 provides the equipment-side transition between these two connector formats without requiring separate breakout boxes or multiple adapter cables.
STEREO ON ONE CONNECTOR
Two Audio Channels on a Single 3.5mm TRS Plug
Unlike dual-XLR or dual-TRS breakout cables, PCM-KW-671 combines the two compatible RJ45 analog audio channels into one conventional stereo mini connector.
This format is useful when the destination equipment expects a conventional stereo 3.5mm connection rather than two separate professional audio connectors.
3.5MM TRS INTERFACE
Compact Stereo Connector for Audio and AV Equipment
The cable terminates in a nickel-plated 3.5mm TRS male connector. The three-contact tip-ring-sleeve format provides two audio signal paths with a common return connection for compatible unbalanced stereo equipment.
Its compact connector size makes the assembly particularly useful with small recorders, computers, media equipment, monitoring devices, audio interfaces and control-room accessories.
APPLICATIONS
Where This Adapter Fits
DEVICE-LEVEL INTERCONNECTION
30cm Length for Clean Workstation and Rack Wiring
The 300mm cable length gives the adapter enough reach for equipment-level connections while avoiding the excess cable associated with standard full-length interconnects.
This makes it suitable for compact workstations, rack-mounted systems, equipment panels, broadcast furniture and other installations where devices are positioned close together.
Stereo Wiring Reference
RJ45 Pin 1
RJ45 Pin 3
RJ45 Pins 2 + 6 + Shell / Braid
The connected equipment should use the corresponding RJ45 audio wiring. Do not assume compatibility based on the RJ45 connector alone.
