Extron’s new DMP 128 Digital Matrix Processor is a 12×8 audio mixer featuring Extron ProDSP, automixing, I/O expansion capabilities and available AEC (acoustic echo cancellation). AEC prevents audio at the near end from being returned to the far end as echo, ensuring clear, natural conversations for far end participants. The DMP 128 offers a configuration approach to DSP that simplifies mixing, routing, conferencing and room optimization. An intuitive configuration system using the DSP Configurator Software allows the DMP 128 to be programmed quickly with adjustments that can be heard in real-time. A digital audio expansion port allows two DMP 128 units to be linked together to expand input and output signal management and routing capabilities.
The DMP 128 C and DMP 128 C P models include Extron AEC for conferencing applications. These models include eight independent channels of AEC, as well as selectable noise cancellation. Extron says its AEC features advanced algorithms that deliver fast echo canceler convergence for optimal intelligibility, even when multiple people are talking at the same time. The DMP 128 C P model includes analog phone interfacing with POTS line and phone connections.
Extron’s ProDSP is engineered from the ground up using a powerful 32/64-bit floating point DSP engine and studio grade 24-bit audio converters with 48 kHz sampling. It is managed by the DSP Configurator Software, a PC-based application featuring a GUI that allows for complete audio system visualization within a single window. Designers can quickly get a snapshot view of the entire audio system, including processing blocks and routing assignments, all at once.
