4-Input, 8-Output 96kHz Loudspeaker Processor and Matrix. Supports networked audio via DANTE and control via Martin Audio's VuNet software, allowing supporting products to be placed under VuNet control along with larger systems being driven by iKon amplifiers.

The Martin Audio DX4.0 is an advanced loudspeaker controller and system matrix with four input and eight output channels. Class-leading sonic performance is achieved by state-of-the-art audio converters and DSP algorithms, with a 96kHz sampling frequency delivering a nominally flat response beyond 40kHz.

Features

  • Four input channels and eight output channels loudspeaker processor and matrix
  • Analogue, AES3 and Dante™ digital audio inputs
  • High performance 96kHz DSP
  • Remote control and monitoring over Ethernet via Martin Audio VU-NET software
  • FIR optimisation for Martin Audio’s O-Line
  • VX limiting allows a passive enclosure the same protection as a fully active unit.
  • Comprehensive suite of EQ’s, delays and all pass filters.
  • Global mains operation 100-240V, 50-60Hz

Applications

  • Loudspeaker system digital controller
  • Front-of-house matrix to feed Dante digital audio to iKON amplifiers powering Martin Audio loudspeaker systems
  • Use with Martin Audio O-Line for FIR Optimisation
  • Use with Martin Audio U-Hub to feed digital audio and network to an MLA Series array/subwoofer array via a single cable
