Eight channels of acoustic echo cancellation (AEC) — The DMP 128 C models
•
include eight independent channels of high performance AEC, as well as selectable
noise cancellation. Extron AEC features advanced algorithms that deliver fast echo
canceler convergence for optimal intelligibility in situations that challenge AEC
performance, including double-talk, and the use of wireless microphones at the near
end.
• Dante™ Audio Networking — Dante equipped DMP 128CP AT models provide
scalable audio transport over a local area network using standard Internet protocols.
Each DMP 128 AT 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 provides
direct interconnection of multiple DMP 128 AT units to create larger, cost-effective
audio matrixes. Both Dante and the DMP 128 AT processor four-port switch are
AVB - Audio Video Bridging ready. Dante is a trademark of Audinate
Digital audio expansion port for linking two DMP 128 units — An expansion port
•
allows any two DMP 128 models to be linked together via a single shielded CAT 6
cable. This allows eight matrix mixes of the inputs, plus eight virtual paths to be sent
and received between units.
• Automixer with eight gate groups — The DMP 128 features an automixer with
advanced features for managing signal levels from multiple microphones. The automixer
includes a gating mode that automatically gates channels on or off, as well as a gain
sharing mode that maintains the overall system gain based on the number of active
mics.
• ProDSP audio signal processing — The DMP 128 features 32/64-bit floating point
audio DSP processing, which maintains very wide dynamic range and audio signal
transparency, to simplify management of gain staging while reducing the possibility of
DSP signal clipping.
48-volt phantom power — The DMP 128 is equipped with selectable 48-volt
•
phantom power for the first eight inputs, allowing the use of condenser microphones.
• 24-bit/48 kHz analog-to-digital and digital-to-analog converters — Fully preserve
the integrity of the original audio signal.
• Fixed, low latency DSP processing — Input to output latency is low within
the DMP 128 and stays constant, regardless of the number of active channels or
processes. While latency increases marginally on channels with AEC enabled, overall
latency remains low. Fixed latency processing keeps audio in sync with video, and
prevents distractions to presenters or performers resulting from delayed live audio.
• DSP Configurator Software — A powerful yet user-friendly PC-based software
tool for managing all audio operations of the DMP 128. It enables complete setup
and configuration of digital audio processing tools on the ProDSP platform, as well as
routing and mixing.
• Intuitive Graphical User Environment — The DSP Configurator Software features
a graphical user environment that offers a clear view of all input and outputs, audio
processing blocks, routing, mix-points, and virtual routing in a single screen. This allows
a designer or installer to quickly view an audio configuration without having to access
multiple dialog boxes or menus.
• Device Manager — Device Manager in the DSP Configurator Software enables
easy configuration of multiple Extron DSP products, including two linked DMP 128
processors, by toggling between graphical user environments for each unit. Processors
can be grouped into folders for organizing as separate rooms or buildings. Settings for
multiple Extron DSP products in the Device Manager can be saved to a single file.
