Digital audio matrix 16×16 analog I/O + 16×16 Dante I/O

The DNM matrices embed Analog Device's SHARC 21489, a powerful digital audio signal processing platform based on a 64-bit floating-point DSP engine. This series offers a wide range of digital processing tools for designing, configuring and optimizing audio systems. The software can fully control and manage the entire DNM series, as well as all their processing functions, including :

  • AFC (adaptive anti-feedback control),
  • AEC (acoustic echo cancellation),
  • ANS (automatic noise cancellation),
  • ANC (ambient noise compensation),
  • "Bessel", "Butterworth" and "Linkwitz-Riley" filters,
  • AGC (automatic gain control),
  • Ducker (multiple priority management by modulation detection),
  • PEQ,
  • GEQ,
  • Delay,
  • Crossover,
  • Automatic mixing with gain sharing,
  • And much more !

The DNM software offers an intuitive graphical user interface, which provides quick and easy access to all channels in a single window. In this user-friendly environment, the audio system designer or installer can clearly view and adjust all input levels, DSP audio processing parameters, mastering and output levels.

All product details

The audio DSP shall have 16 balanced inputs and 16 balanced output channels for microphone or line-level analog audio signals, each independently controllable with removable euro block connectors. The DSP shall have Dante® digital audio networking up to 16 input and 16 output channels on 2 RJ-45 jacks, an Ethernet connection for control and programming on a separate RJ-45 jack, USB audio, and 8 channels of configurable GPIO and 2 serial ports on a removable euro block.
