DMP 128 FlexPlus • Introduction 2
• Twelve channels of AEC - acoustic echo cancellation — The DMP 128 FlexPlus includes twelve
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.
• All models include a USB Audio interface, providing up to four channels of digital audio sends and
returns — Support for USB Audio simplifies implementation of systems with either soft-codec conferencing or
computer-based audio and enables use of the same interface for both small- and large-scale systems.
• V-model includes up to eight VoIP lines that support generic Session Initiation Protocol - SIP 2.0
connectivity per RFC 3261 — The DMP FlexPlus C V AT is compatible with select VoIP systems and can be
used for a single VoIP line or as a VoIP farm for up to eight rooms.
• Compact half rack size — Allows more input and output channels, with more processing power, to be
installed in less space.
• FlexInput capability on main inputs — All twelve main inputs offer FlexInput capability to select a Dante
channel, expansion input, or one of the four mic/line inputs. This allows incorporating the full range of DSP
capabilities, including AEC, for incoming Dante channels.
• Optional ACP Series audio control panels provide intuitive audio system control — Direct interface
with the DMP 128 FlexPlus offers flexible audio control for systems that do not require a full control system.
• Digital I/O ports for remote control or feedback — Two digital input ports and two digital output ports are
provided, so that the DMP 128 FlexPlus can be programmed to sense and then respond to external triggers
such as mic activation, muting, and recall of presets.
• Macros allow the sequencing of commands that can be sent to the local device or external devices via
the LAN port — A single DMP 128 FlexPlus can act as the central interface from a control system, sending
commands to other DMP, AXI AT, and DTP CrossPoint devices.
• Aux inputs and outputs can be individually configured as audio file players, USB Audio, or in the
V-model, VoIP lines — Audio file players can be allocated to any aux input and used to play back
prerecorded content. USB Audio and VoIP can be allocated to any aux input and any aux output. In these
cases, the aux inputs function like returns and the aux outputs function like sends. For USB audio, that would
be sends and returns to/from a room PC running a software codec, and VoIP would be sends and returns to/
from the central VoIP PBX.
• Advanced audio processing on all eight analog outputs and all 16 direct Dante/Expansion outputs —
Up to 24 speaker zones can be implemented on one DMP 128 FlexPlus with full processing for each zone,
making it ideal for full mix-minus implementations.
• Extensive mix matrixing in every DMP 128 FlexPlus allows all inputs to be discretely routed to any or
all outputs — Allows all 12 main inputs, 8 aux inputs, 48 Dante inputs and 16 virtual bus returns to be
discretely routed to any or all of the 8 analog outputs, 4 aux outputs, 24 Dante outputs and the 16 virtual bus
sends.
• 16 virtual processing loops allow for great flexibility in sub-mixing and processing — Processing
common to many inputs can be applied using a single virtual channel.
• Up to eight audio file players can be used to play back audio files for system set-up or as part of the
system design — Use the provided pink noise, white noise, and sine wave files, or import your own WAV,
MP3,WMA,AIFF,AAC,orRAWfiles.Supportedfileformatsareautomaticallyconvertedto24-bit,48kHz
RAW for approximately 20 minutes of playback time and saved to the onboard storage.
• Low latency — Powerful DSP chips maximize performance, resulting in latency that is very low, from input to
output, regardless of the number of active channels or processes. While latency increases in channels with
AEC enabled, and marginally with the automixer, overall latency remains low. This keeps audio in sync with
video, and prevents distractions to presenters or performers resulting from delayed live audio.
