DSPs (Digital Signal Processors)

Extron – DMP 64 Plus C V AT

The Extron DMP 64 Plus series of compact Digital Matrix Processors features six DSP input channels with AEC, in only a half rack space. With a flexible mix matrix, a USB audio interface, and 6×4 analog connectivity, the DMP 64 Plus provides the ability to easily connect and route signals to accommodate system requirements. The AT models can be powered by PoE+ and provide 32×16 Dante connectivity for popular Dante microphone arrays, and other Dante devices, while the V models include up to eight VoIP lines for collaboration applications. Featuring an ACP bus for audio control panels, an expansion port for bidirectional digital audio connection with a DTP CrossPoint® or another DMP, eight audio file players, and configurable macros, the DMP 64 Plus can be used in a wide variety of smaller systems.


  • Four models – The DMP 64 Plus offers signal routing and management for a wide range of sound system applications:
    • Inputs: 32 Digital via Dante or Expansion Bus, 6 Analog balanced/unbalanced mic/line level, 8 Aux for USB or VoIP
    • Outputs: 16 Digital via Dante or Expansion Bus, 4 Analog balanced/unbalanced line level, 8 Aux for USB, VoIP or File Players
  • 32×16 Dante audio networking with Dante Domain Manager and AES67 support — Dante audio networking provides scalability for creating larger audio matrixes over a local area network using standard protocols. A built in two port Gigabit switch can be configured to support primary and redundant Dante audio networks.
  • Six channels of AEC – acoustic echo cancellation — The DMP 64 Plus includes six independent channels of high performance AEC, as well as selectable noise cancellation. Extron AEC features advanced algorithms that deliver fast echo canceler convergence for optimal intelligibility in situations that challenge AEC performance.
  • Ability to be powered over PoE+ on AT models
  • All models include a USB Audio interface, providing up to four channels of digital audio sends and returns — Support for USB Audio simplifies implementation of systems with either soft-codec conferencing or computer-based audio and enables use of the same interface for both small and large scale systems.
  • V model includes up to eight VoIP lines that support generic Session Initiation Protocol – SIP 2.0 connectivity per RFC 3261— The DMP 64 Plus C V AT is compatible with select VoIP systems and can be used for a single VoIP line or as a VoIP farm for up to eight rooms:
    • VoIP configuration via onboard web page separates AV and IT workflows
    • Flexible local conference calling with Extron exclusive independent audio processing and control per call – level, mute, hold, and hang-up per caller
    • Onboard SIP logging eliminates the need for network capture software
    • Supports standard and wideband codecs, with selectable priority
    • Quality of Service – QoS support for Layer 2 and Layer 3
    • Transport Layer Security – TLS and Secure Real-Time Transport Protocol – SRTP ensures industry standard call security
    • NAT Traversal supported via STUN, TURN, and ICE simplifies integration across challenging network topologies
    • VLAN support via 802.11Q Tags
