Extron is shipping the DMP 128 AT and DMP 128 C AT audio digital signal processors with Dante network connectivity from Audinate. Both DMP 128 models are 12×8 audio mixers featuring Extron ProDSP, automixing and I/O expansion capabilities. The DMP 128 C AT version also features AEC — acoustic echo cancellation. DMP 128 AT models feature a 56 input by 24 output expansion matrix, providing efficient scalability for creating larger audio matrices over a local area network using standard Internet Protocols. A built-in four-port Gigabit switch provides direct interconnection of multiple DMP 128 AT units. The award-winning DMP 128 Series offers a configuration approach to DSP that simplifies mixing, routing, conferencing and room optimization. Quick and intuitive 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.

DMP 128 AT models 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 four-port Gigabit switch also provides direct interconnection of multiple DMP 128 AT units to create larger, cost-effective audio matrixes. Dante technology distributes a virtually unlimited 512×512 audio channels at 24-bit/48 kHz over a single Gigabit Ethernet link, or 48×48 audio channels at 24-bit/48 kHz over a single 100 Mbps Ethernet link, plus integrated control data with extremely low latency. Both Dante and the DMP 128 AT processor’s four-port switch are AVB – Audio Video Bridging ready.

The DMP 128 features Extron ProDSP, engineered from the ground up using a powerful 64-bit floating point DSP engine and studio grade 24-bit converters with 48 kHz sampling. ProDSP is managed by the intuitive DSP Configurator Software, featuring an easy-to-use 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. Select DMP 128 processors feature Extron AEC with eight independent channels of high performance, fast echo cancellation for optimal intelligibility in conferencing applications.
