Building on their success and wide adoption, the next generation of PacketAV™ Duet endpoints deliver powerful 4K UHD Video, Dante™/AES67 connectivity, and control, all via a single Main Gigabit LAN port. USB-C connectivity is standard, offering easy connection for sharing media via laptop, tablet, phone, or other USB-C connected devices, as well as enabling soft-codec integration via driverless USB 2.0 connection to a PC for web conferencing applications such as Zoom, Skype, Cisco WebEx, and Microsoft Teams.

The PacketAV™ Duet 2 Encoders & Decoders are also equipped with an Ethernet Expansion port, enabling network connectivity for control and managed IP traffic pass-through to remote devices including projectors, displays, and touch panel controllers. This expansion port also supports Power Over Ethernet (PoE) pass-through to connected devices for added flexibility.

Duet 2 encoders also offer multiple selectable local input sources with HDMI loop-through, enabling automatic switching between USB-C and dual HDMI input sources via input detect mode, or via programmed control system or web browser.
