Inputs — Twelve balanced or unbalanced mic/line level on 3.5 mm, 3-pole and
6-pole captive screw connectors, eight with phantom power.

Outputs — Eight balanced or unbalanced line level on 3.5 mm, 6-pole captive screw
connectors.

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 128P AT models provide
scalable audio transport over a local area network using standard Internet protocols.
Each DMP 128P 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 128P AT units to create larger, cost-effective
audio matrixes. Both Dante and the DMP 128P 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.
