Overview
The Enova® DVX-2255HD 6x3 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-2255HD is a simple to
install, flexible solution, perfectly suited for large and complex conference rooms,
classrooms and auditoriums.
The DVX-2255HD 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-2255HD 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 DVX2255HD'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-2255HD 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.
Common Applications
The DVX-2255HD is ideal for dramatically simplifying AV control and distribution in small to medium-sized
and large conference rooms, boardrooms and classrooms.
With the included DXLink inputs, the DVX-2255HD is perfect for rooms where the AV rack is not near your
source devices and display
The flexible DVX-2255HD 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-2255HD is perfect for any room or facility with space constraints, especially those that lack space in
equipment racks.
Features
All-In-One Device – Controller, matrix switcher, scaler, analog to digital converter, amplifier, plus twisted pair
distribution and professional-grade audio DSP – all in a space-saving 3U chassis
Simplicity & Reliability – Replaces the need for numerous individual components and equipment, ensuring
high reliability and saving on configuring and programming costs
Low Total Cost of Ownership – With a consistent platform across a variety of sizes, it is easy to standardize
on the the DVX and reduce costs for hardware, training, support, troubleshooting and sparing
Unrivaled Network Security: Dual NIC – The LAN port is used to connect the master to an external network,
and the ICSLAN ports connect to AMX or third-party AV equipment isolated from the primary network,
providing rock-solid security
IPv6 and wired 802.1x – Supports modern networking standards for internet protocol IPv6 and port-based
Network Access Control utilizing X.509 certificates for access to protected networks

independent 10-band parametric EQ, independent input gain adjustments and variable compression, allow
precision tuning to match unique source and room attributes
Audio Breakaway – Stereo audio from any analog input or de-embedded from any HDMI input can be
broken away from its associated video, processed through the DSP, and switched independently to any
analog, HDMI or S/PDIF audio output
Audio Matrix Switching – Three independently switched and processed audio paths provide four unique
volume, EQ, ducking and mixing configurations for perfectly tuned room audio as well as integration with
audio/video conferencing, induction loop systems, voice re-enforcement speakers and audio recording
devices
Enhanced Microphone Processing – Independent 3-band parametric EQ, compression, gating, auto-ducking,
and limiting on each microphone input ensures crystal clear communication
