Extron Unveils ‘DMP 128’ Audio Mixer

The DMP 128 was designed to provide a larger 12x8 audio matrix mixer and acoustic echo cancellation

Extron Electronics, a manufacturer of professional audiovisual system integration products, unveils the Digital Matrix Processor (DMP) 128, which is a 12×8 audio mixer featuring Extron ProDSP, automixing, input/output (I/O) expansion capabilities and acoustic echo cancellation (AEC).

The DMP 128 offers a configuration approach to digital signal processing (DSP) that simplifies mixing, routing, conferencing and room optimization, Extron says. The DSP Configurator Software enables the DMP 128 to be installed in very little time, with easy-to-learn adjustments that can be heard in real-time.

In addition, a digital audio expansion port enables two DMP 128 units to be linked together to expand input and output signal management and routing capabilities, the company says. The DMP 128 is “ideal for presentation and conferencing applications in boardrooms, courtrooms and conference centers that require advanced matrix mixing with DSP,” Extron says.

“The DMP 128 is our latest ProDSP processor, offering what our customers have been requesting a larger 12×8 audio matrix mixer and acoustic echo cancellation,” says Casey Hall, Extron’s vice president of sales and marketing. “Extron AEC employs advanced processing engineered for robust, dependable echo cancellation in videoconference scenarios and is very easy to set up and configure within the user-friendly DSP Configurator Software,” Hall says. “An expansion port enables further flexibility for sound system designers working with larger systems, allowing two DMP 128 units to be linked to create an expanded matrix.”

The DMP 128 C and DMP 128 C P models include Extron AEC for conferencing applications. AEC prevents audio at the near end from being returned to the far end as echo, ensuring clear, natural conversations for far end participants.

Those models include eight independent channels of high performance AEC, as well as selectable noise cancellation. AEC processing can be challenged by conditions such as double-talk, when talkers from both ends are speaking simultaneously and when near end talkers use wireless microphones. Extron AEC features advanced algorithms that deliver fast echo canceler convergence for optimal intelligibility, even in challenging conditions.
