AVBridge

What the AVBridge does in a conferencing room

The Yealink AVBridge is a wired audio box that also extends audio and video signals. It takes signals from ceiling microphones, analog sources, cameras and other AV devices and carries them to the conferencing host, so the room's audio chain can be built around one small unit. It is not a wireless presentation dongle. Its listed functions are audio processing, Dante networking and A/V extension, so plan it as part of the audio and cabling design.

Because it combines audio processing with signal extension, it is most useful where a room needs more control than the audio built into a camera or codec provides. It sits between a basic setup and a fuller Pro AV installation.

Audio and connection facts that shape your design

• 4 × 4 Dante channels with AES67 and Dante protocol support, for routing audio across a Dante network
• 1 × 3-pin Phoenix analog input with 0 to 11 dB of analog input gain
• 1 × 5-pin Phoenix analog output with a limiting range of -10 dBV to +4 dBu
• Matrix mixer and PEQ for custom routing and foundational room tuning
• 100 Hz to 20 kHz frequency response, up to 24-bit depth and 48 kHz sampling
• RJ45 connector using Cat5e or higher cable, with shielded cable recommended

Pairing with CM20 and CM50 ceiling microphones

The unit is designed to work with Yealink CM20 and CM50 ceiling microphones, the combination that makes it a standard video conferencing audio solution. The specification lists support for up to four CM20 units alongside Yealink speakers and third-party Dante or analog speakers. For CM50 quantities and speaker counts in a medium or large room, confirm the configuration with the SmartRooms Qatar team against your room drawings before ordering.

Where it fits in Qatar

In a boardroom in West Bay, the AVBridge can carry ceiling microphone audio from the conference table into the video system while the camera and display stay on their own cabling. In a multi-purpose hall at a private school in Al Wakrah, it can connect a set of Dante-networked speakers and analog sources within one room audio chain. In a training room in Education City, the matrix mixer can route audio to the zones of the room that need it.

Planning the installation

• The operating temperature range is 0 to 40 °C with 0 to 95% RH humidity. Outdoor summer temperatures in Qatar exceed 45 °C, so place the unit in an air-conditioned room or a cooled, ventilated ceiling void rather than an unventilated cabinet.
• Power comes over Ethernet, drawing 8 W with no load and 13 W at full load, so check the PoE budget of the network switch serving the room.
• Dimensions are 150 × 100 × 28 mm and weight is 315 g. The Yealink Room Designer software supports setup.
• Use Cat5e or higher shielded cabling terminated at the RJ45 port.
