The Extron DMP 64 Plus series of compact Digital Matrix Processors features six DSP input channels with AEC, in only a half rack space. With a flexible mix matrix, a USB audio interface, and 6×4 analog connectivity, the DMP 64 Plus provides the ability to easily connect and route signals to accommodate system requirements. The AT models can be powered by PoE+ and provide 32×16 Dante connectivity for popular Dante microphone arrays, and other Dante devices, while the V models include up to eight VoIP lines for collaboration applications. Featuring an ACP bus for audio control panels, an expansion port for bidirectional digital audio connection with a DTP CrossPoint® or another DMP, eight audio file players, and configurable macros, the DMP 64 Plus can be used in a wide variety of smaller systems.

Acoustic Echo Cancellation
The DMP 64 Plus series includes Extron AEC for conferencing applications. AEC is essential for effective remote room-to-room conversations, ensuring clear, natural communication for all participants. These models include six 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.

The DSP Configurator™ Software simplifies AEC and noise cancellation setup with a user-friendly interface that provides real-time metering for ERL – Echo Return Loss, ERLE – Echo Return Loss Enhancement, and TER – Total Echo Reduction levels. Guided alerts appear whenever ERL is outside of the optimal range for echo cancellation and DSP templates serve as starting points with routing optimized for AEC workflows. Optional settings include fine adjustments for NLP – Non-Linear Processing to maximize AEC performance in acoustic environments with significant sonic reflections or reverberation.

Dante Connectivity
The Dante-equipped DMP 64 Plus AT models provide scalable audio transport, with Dante Domain Manager support, over a local area network using standard network protocols. Each DMP 64 Plus AT model sends out 16 channels of digital audio and can receive 32 channels over the network, offering easy connectivity to popular Dante microphones. A built-in two-port Gigabit switch provides direct connection to other Dante-enabled devices to create simplified, cost effective audio systems. Additionally, the DMP 64 Plus AT models can be configured to support primary and redundant Dante audio networks, as well as AES67 compatibility. Setting up a network of Extron Dante-enabled audio devices requires Dante Controller, and Extron DSP Configurator Software.

Power Over Ethernet
The AT models with Dante connectivity can be powered by PoE+.

FlexInputs
All six main DSP channels of the DMP 64 Plus offer FlexInput source selection to route any Dante input, expansion input, or one of the six mic/line inputs, to a main DSP channel. This enables the DMP 64 Plus to process audio from any source with the full range of DSP capabilities, including AEC.

VoIP – Voice over Internet Protocol Capability
The DMP 64 Plus V models include up to eight SIP 2.0 VoIP lines, with wideband codec support, that can be configured as individual extensions or with multiple call appearance channels to support local conferencing applications. Compatible with select VoIP systems, any single V model of the DMP 64 Plus series can be used for a single VoIP line or as a VoIP farm for up to eight rooms.

USB Audio Interface
The included USB audio interface provides connectivity to a computer for use with soft CODEC applications and computer sourced audio. The input/output configuration of the USB Audio Interface can be set to 0x8, 2×6, 4×4, 6×2, or 8×0. This allows for more input or output streams, as required by the system application.

Automixer
The DMP 64 Plus series features an automixer with gated and gain sharing modes that can manage up to eight groups of microphone signals. Gating threshold, signal level reduction, and timing parameters are user-adjustable per channel. This allows for fine-tuning to avoid the “chopped” sound characteristic of a traditional automixer when a mic is gated off. As the number of active microphones is doubled, system gain is automatically reduced, uniformly attenuating microphone signal levels to minimize audible changes in the overall sound and the possibility of feedback. For a natural sounding mic mix, the automixer also offers a gain sharing mode which allows all mics to remain on, while the gain for each mic is adjusted in real time to ensure a constant system gain.

Powerful Routing Across Two ProDSP Processors
The DMP EXP expansion port allows two Extron DSP units to be linked together via a single shielded CAT 6 cable. This creates a 16 channel bi-directional 24-bit/48 kHz high-resolution digital audio expansion bus between the two units, allowing expanded input and output signal management and routing capabilities. This expanded 16×16 I/O channel transport between devices allows designers to create audio mixes with advanced I/O and signal management scenarios combining the capabilities of two processors. The expansion port is also available on Extron DTP CrossPoint matrix switchers. This allows a 16×16 I/O channel transport between the matrix switcher and a DMP 64 Plus to expand the number of available audio inputs for a DTP System, and to offer additional capabilities such as automixing, AEC – Acoustic Echo Cancellation, and VoIP – Voice over Internet Protocol.

Versatile Control Options
Each model is equipped with an ACP port to support the use of Extron Audio Control Panels. Audio Control Panels offer an economical way to provide volume control, source selection, and preset recall in configurations that do not require a full control system. A DMP 64 Plus can also be controlled and configured via RS-232 serial control, Ethernet control, or USB. Each model also includes digital I/O ports, which allow for external triggering such as mic activation and muting.

ProDSP
Extron’s exclusive ProDSP is engineered from the ground up using a powerful 64‑bit floating point DSP engine to provide very wide dynamic range and reduce the potential for clipping. ProDSP also utilizes studio grade 24‑bit audio converters with 48 kHz sampling to maintain audio signal transparency. ProDSP is loaded with powerful, easy‑to‑configure tools to control level, adaptive gain, automixing, dynamics, filters, delay, ducking, loudness, feedback suppression, and AEC.

Easy-to-Use DSP Configurator Software
The power of ProDSP is easily harnessed with the DSP Configurator Software. The flexible on‑screen layout offers fast access to all of the digital audio signal processing tools. Designers can quickly get a snapshot view of the entire audio system, including processing blocks and routing assignments, all at once.
