+- Print Email Share RSS RSS

Extron Electronics has announced the immediate availability of all DMP 128 Series audio digital signal processors, including models with Dante audio networking, AEC (acoustic echo cancellation), and analog telephone connectivity.

The DMP 128 Series are 12 x 8 audio mixers with Extron ProDSP, automixing, and I/O expansion capabilities. The DMP 128 C P and DMP 128 C P AT are the newest models shipping, and feature POTS - plain old telephone service capability for connection to an analog phone line and handset.

The DMP 128 Series offers a configuration approach to DSP that simplifies mixing, routing, conferencing, and room optimization. Configuration using the DSP Configurator software allows the DMP 128 to be installed in very little time, with easy-to-learn adjustments that can be heard in real-time.

“We are pleased that all DMP 128 models are now immediately available for a wide range of audio presentation applications, from single-room conferencing systems to large-scale audio networks,” says Casey Hall, vice president of sales and marketing for Extron. “Whatever the application, the DMP 128 is very easy to set up and configure through the intuitive software application.”

The DMP 128 features Extron ProDSP, engineered from the ground up using a 64-bit floating point DSP engine and 24-bit converters with 48 kHz sampling. ProDSP is managed by the intuitive DSP Configurator software with GUI that allows for complete audio system visualization within a single window.

All DMP 128 models include an automixer with gated and gain sharing modes for managing up to eight groups of microphone signals.

DMP 128 C models have Extron AEC with eight independent channels of high performance, fast echo cancellation for optimal intelligibility in conferencing applications.

DMP 128 P models include analog phone interfacing with POTS line and handset connections, allowing users to answer and initiate calls to remote attendees over the PSTN—public switched telephone network or in a PBX - private branch exchange.

DMP 128 AT models with Dante provide scalable audio transport over a local area network using standard Internet protocols. Each processor sends out 24 channels of 24 bit/48 kHz digital audio and can receive 56 channels over the network.

A built-in 4-port Gigabit switch also provides direct interconnection of multiple DMP 128 AT units to create larger, cost-effective audio matrixes.
