  • High Performance Switcher Transmitter — Professional HDBaseT Switcher transmitter for providing long–reach signals over twisted pair copper infrastructures. This switcher transmitter is a standard transmitter that can be connected to any market–available HDBaseT–compliant extension product.
  • Simple and Powerful Maestro Room Control — Out–of–the–box configured room control for a typical meeting room setup, and intuitive user interface enables you to control your meeting room elements. Room devices are controlled, locally or remotely via HDBaseT, right out–of–the–box by an extensive range of triggers, including input/output connectivity and routing. By minimizing user intervention, Maestro room control saves meeting prep time and minimizes human error before presentations.
  • Automatic Display Operation — Part of the out–of–the–box Maestro configured room automation. Meeting presentation is simplified by automatically turning ON/OFF a CEC–enabled display when the presentation source is plugged in / unplugged with user–defined shut–down delay.
  • BYOD Ease and Convenience — Connect any DP–Alt–Mode–capable USB–C device as an AV presentation source, while providing the connected device, if PD–2.0–capable, with up to 60 watts of power (with the use of an optional 20V power supply).
  • Plug & Play Auto Switcher — Automatically plays the switched user device source signal on the connected display according to user–configured preferences, such as priority or last–connected input. When the user manually switches, by pressing a button, the auto switching is overridden.
  • HDMI™ Signal Switching — HDCP 2.3 compliant, supporting deep color, x.v.Color™, lip sync, HDMI uncompressed audio channels, Dolby TrueHD, DTS–HD, 2K, 4K, and 3D as specified in HDMI 2.0.
  • I–EDIDPro™ Kramer Intelligent EDID Processing™ — Intelligent EDID handling, processing, locking and pass–through algorithm ensures plug & play operation for HDMI source and display systems.
  • Multi–channel Audio Switching — Up to 8 channels of digital stereo uncompressed signals for supporting studio–grade surround sound.
  • Audio De–embedding — The digital audio signal passing–through to the output, is de–embedded, converted to an analog signal and sent to the stereo analog audio output. This enables playing the audio on locally connected speakers, in parallel to playing it on the speakers connected to the AV acceptor device (such as TVs with speakers).
  • Bidirectional RS–232 Extension — Serial interface data flows in both directions, allowing data transmission and device control.
  • Reliable PoE (Power over Ethernet) Powering — Auto–senses the HDBaseT extension line PoE status, it accepts power from a remote PoE provider such as a PoE matrix, with optional mains powering from connected power adapter.
  • Cost–effective Maintenance and Management — Status LED indicators for Power, HDMI, and HDBT ports facilitate easy local maintenance and troubleshooting. Local device management using built–in web interface via the USB–C connection . Local firmware upgrade via USB–C and RS–232 connection tool ensure lasting, field–proven deployment.
  • Easy Installation — Compactly fits into standard US, EU and UK 1–gang in–wall box size, supporting decorative integration with room deployed user interfaces such as electrical switches. Wall–plate installation is fast and cost–effective via a single twisted pair cable, providing both video signal and power (PoC) connections.
