Biamp Devio SCR-20TX Black Conferencing Hub with 4K HDMI, PoE+, and 2x15W Amplifier

The Biamp Devio SCR-20TX stands apart from typical USB conferencing bars by functioning as a dedicated collaboration processor that connects a single Biamp Devio microphone, room display, and speakers into a streamlined UC platform. Unlike all-in-one devices that force compromises in mic placement or speaker quality, this half-rack hub lets you design the room audio around the table and walls, while the SCR-20TX handles echo cancellation, noise reduction, and automatic mixing with pro-grade precision.

Highlights

• Single-cable connection to Biamp Devio ceiling or table microphone via RJ-45
• Built-in 2 x 15W amplifier drives 8Ω speakers directly — no external amp needed
• HDMI 1.4b input and output support 4K UHD video at 30Hz for crisp content sharing
• USB 3.0 Type-B to host PC plus two USB 3.0 Type-A ports for camera or touch display
• PoE+ (802.3at) powers the entire hub, simplifying installation and reducing cable clutter
• Compatible with Microsoft Teams, Zoom, Google Meet, and other major UC platforms
• Flexible mounting: half-rack 1RU or surface mount under a table or behind a display

In daily use

In a huddle room or small conference space, the SCR-20TX becomes the silent engine behind every call. Connect the Devio microphone, plug in the room's HDMI display and camera, attach a pair of 8Ω speakers, and run a single USB cable to the room PC. The hub automatically manages acoustic echo cancellation, noise reduction, and automatic gain control, so participants sound clear without manual tweaking. When a laptop user walks in, they can simply connect via USB and use the room's audio and video through the same processor. The web UI, Telnet, or SNMP give IT staff remote monitoring and control, while the PoE+ power means no separate power brick is needed if your network switch supports it.
