The Enova® DVX-3255HD 10x4 All-In-One Presentation Switcher is a unified audio, video, and control device that replaces the need for numerous individual components and eliminates the integration and reliability challenges that accompany them. The compact 3U Presentation Switcher integrates a variety of different functionality, such as a scaler, analog to digital signal converter, twisted pair transmitter and amplifier with built-in professional grade audio processing into a single chassis. With AMX-exclusive features, the DVX-3255HD is a simple to install, flexible solution, perfectly suited for large and complex conference rooms, classrooms and auditoriums.

The DVX-3255HD includes the next generation NetLinx Integrated Controller technology, the NX-Series. This new controller provides a scalable platform for the future by combining high performance, backward compatibility and extensive network security features.

The DVX-3255HD includes a long list of features to ensure optimal audio and video quality from virtually any source. The state-of-the-art professional grade audio DSP delivers quality audio throughout a room. The DVX-3255HD's multi-format video inputs support analog and digital signals including HDMI with HDCP sources - all in the same connector. Built-in SmartScale® Technology outputs video that is perfectly scaled for each connected display, eliminating the integration challenges that can occur when sources and displays have different optimal resolutions - making the DVX-3255HD easy to specify, easy to install and easy to use.

The Enova DVX's all-in-one architecture also delivers the lowest Total Cost of Ownership in the industry, thanks to ease of support, maintenance and configuration, as well as reduced hardware and cabling costs.


  • The DVX-3255HD is ideal for dramatically simplifying AV control and distribution in medium-sized and large conference rooms, boardrooms, classrooms, lecture halls and auditoriums.
  • With the included DXLink inputs, the DVX-3255HD is perfect for rooms where the AV rack is not near your source devices and display
  • The flexible DVX-3255HD is perfect for any complex collaboration space with a mix of analog and digital sources, multiple displays, or rooms that require support for video conferencing.
  • The DVX-3255HD is perfect for any room or facility with space constraints, especially those that lack space in equipment racks.
