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.
