DigitalMedia™ Presentation System 300 w/Acoustic Echo Cancellation

An enhanced version of the DMPS-300-C featuring full-bandwidth acoustic echo cancellation.

The DMPS-300-C-AEC from Crestron® is a complete, high-definition presentation control and signal routing solution for boardrooms and videoconference rooms. Integrating the control system, multimedia matrix switcher, mic mixer with AEC, audio DSP, and amplifier all into one 3-space rack mount package, the DMPS-300-C-AEC affords extensive signal routing flexibility and high-performance signal processing without the need for separate components. Auto-configuring inputs enable plug-and-play compatibility with a wide range of digital and analog sources. Built-in DigitalMedia™ and HDBaseT® connectivity affords a streamlined wiring solution for interfacing with remote AV sources, computers, and display devices.

The DMPS-300-C-AEC is an enhanced version of the DMPS-300-C featuring full-bandwidth acoustic echo cancellation on each of its six mic inputs. It integrates directly with up to two audio or video codecs for a total teleconferencing system solution.

HD System Switcher
The DMPS-300-C-AEC provides high-performance routing of numerous digital and analog sources to up to four separate projectors, flat panel displays, codecs, touch screens, and other devices. Connectivity is provided for up to five HDMI® sources[1], or other combinations of HDMI, RGB, SPDIF, analog audio, and analog video sources (plus additional remote sources via DM 8G+® or HDBaseT). Input auto-detection and auto-switching eliminates the need to configure the inputs - simply connect your source and the DMPS-300-C-AEC selects the right audio and video combination. Built-in matrix switching allows routing of seven simultaneous sources to four different digital AV devices and three additional analog audio components.

Flexible Audio Routing
The HDMI, SPDIF, and analog audio inputs may be configured to follow their associated video inputs, or switched independently. In fact, the audio from any HDMI source can be extracted from the digital stream and converted to analog to feed an outboard processor, mixer, or codec, with the return signal feeding back through any analog input, which can be embedded with any video source to form a new HDMI output. Routing of multi-channel PCM, Dolby®, and DTS® audio sources is supported through the HDMI and DM 8G+ outputs. The HDMI, SPDIF, and analog audio inputs include adjustable input compensation to accommodate a wide range of signals and maintain consistent volume levels when switching between sources.

DigitalMedia 8G+®
Integrated DM 8G+ inputs and outputs afford the ultimate in simplicity, providing a true one-wire interface for remote sources and display devices. Easily add up to two DM 8G+ transmitters to provide connectivity for HD AV sources and computers at a table or lectern. Connect two DM 8G+ receivers to provide independent signal routing and control for two separate projectors or flat panel displays. Supporting wire lengths up to 330 feet (100 meters), DM 8G+ can also provide an ideal interface to a central DigitalMedia switcher as part of a larger multi-room or room-combining system.

DM 8G+ requires just one CAT5e wire run to each location, transporting high-definition video, audio, and Ethernet for each device without compromise. Power over DM (PoDM) is supplied over the same CAT5e connection, providing a centralized power source for all compatible transmitters and receivers.[2,3]

HDBaseT® Certified
Crestron DigitalMedia 8G+ technology is designed using HDBaseT Alliance specifications, ensuring interoperability with third-party HDBaseT products. Via DM 8G+, the DMPS-300-C-AEC can be connected directly to any HDBaseT compliant source or display device without requiring a DM® transmitter or receiver.

6-Channel Microphone Mixer
For a complete presentation or conferencing solution, the DMPS-300-C-AEC includes built-in mixing and processing for six microphones. Each mic input provides selectable mic or line level with 60 dB of gain adjustment, switchable 48V phantom power, fully-adjustable gating, compression, limiting, and 4-band EQ. Sophisticated matrix mixing allows for a completely different stereo mix of all 6 microphones at each of the DMPS-300-C-AEC's seven outputs.

Acoustic Echo Cancellation
High-performance adaptive AEC on each mic input enables the DMPS-300-C-AEC to be connected directly to audio and video codecs to form a complete teleconferencing system solution. Low-latency, full-bandwidth performance affords highly-effective echo cancellation with natural sound quality. AEC is employed independently per microphone, with a fast convergence rate of 80 dB per second and tail lengths up to 200 ms, allowing the DMPS-300-C-AEC to handle any typical small to medium sized room with ease.

Expanded signal routing and audio processing in the DMPS-300-C-AEC allows one or two codecs to be connected to any of the seven source inputs, and either (or both) of the aux outputs. Dual codec support allows both codecs to be used simultaneously, even allowing the signal from one codec to be fed to the other for a fully inclusive teleconferencing experience. Plus, any local presentation source can be mixed with the microphones and routed to the codecs, allowing far end participants to experience the full presentation without any distracting echo.

Professional Audio DSP
Each analog audio output on the DMPS-300-C-AEC includes its own digital signal processor, allowing each output to be optimized to feed a power amplifier, codec, recorder, or assistive listening system. In addition to real-time adjustable volume, bass, treble, and mute controls, each DSP provides 10-band graphic equalization, 2-band parametric equalization, and 85 ms speaker delay adjustment. Hardware relay muting on each output helps prevent "thumping" on power up.

An additional dedicated DSP is included to process the AEC reference signal inside the DMPS-300-C-AEC, allowing its EQ and volume level to be set to track that of the main program output feeding the room speakers. In some situations, this can reduce the demand on the AEC's adaptive filter for even more transparent performance.

Built-in Amplifier
Its built-in 40-watt amplifier allows the DMPS-300-C-AEC to directly drive a pair of stereo speakers, or a string of 70 or 100 Volt ceiling speakers. Fed by the main "Program" output, the internal amplifier benefits fully from the onboard DSP. For larger applications, Crestron AMP-Series power amplifiers may be added, providing a complete solution for driving separate program and speech speakers, or any multi-zone loudspeaker system.

EDID Format Management
The DMPS-300-C-AEC allows for management of the EDID (Extended Display Identification Data) information that passes between the display devices and input sources in the system. Using Crestron Toolbox™ software, the format and resolution capabilities of each device can be assessed, allowing the installer to configure EDID signals appropriately for the most desirable and predictable behavior.

A Scaler for Every Display
Through a distributed scaler approach, the DMPS-300-C-AEC affords a very flexible and user-friendly solution for handling multiple disparate display devices and video codecs. Employing discrete outboard scalers like the HD-SCALER[4] and DM-RMC-SCALER-C[4], the DMPS-300-C-AEC allows an independent high-performance scaler to be installed at every display device and in front of each codec, ensuring an optimal image on every screen no matter what sources are selected.

QuickSwitch HD® Technology
Handling high-definition digital media means handling HDCP (High-bandwidth Digital Content Protection), the encryption scheme used by content providers to protect their DVDs, Blu-ray™ discs, and broadcast signals against unauthorized copying. Viewing HDCP encrypted content requires a source device to "authenticate" each display and signal processor in the system and issue it a "key" before delivering an output signal.

Using a conventional HDMI or DVI switcher, it is common to experience a complete loss of signal for up to 15 seconds during the authentication process each time a new source or display is selected anywhere in the system. Also, every source device has a limited number of keys available, so connect too many displays and the source will simply stop outputting a signal without warning.

Crestron QuickSwitch HD manages the keys for every HDCP-compliant device in the system, maintaining continuous authentication for each device to ensure fast, reliable routing of any source to any number of display devices.

Auto-Locking™ Technology
Crestron Auto-Locking Technology enables super fast signal switching by instantaneously configuring every device in the signal path, including DM transmitters, DM receivers, and scalers, as soon as the signal hits the first device. Whether switching between sources or TV channels, Auto-Locking significantly reduces the time it takes each device to sense the new signal and configure itself to handle the changes, virtually eliminating any noticeable gap while switching.

Built-in Ethernet Switch
In addition to transporting digital video and audio, the DigitalMedia 8G+ ports on the DMPS-300-C-AEC can also extend Ethernet out to each display and source device, providing high-speed connectivity for each room device that requires a LAN connection. Ethernet is also utilized internally by the Crestron control bus to manage each transmitter and receiver and provide device control.

Private Network Mode
To streamline its implementation on a corporate or university LAN, the DMPS-300-C-AEC employs Private Network Mode to provide a single-point connection for the complete system. Using Private Network Mode, the DMPS-300-C-AEC requires just one IP address for the complete DM network, plus one additional IP address for the built-in control processor.

Integrated Control System
Its built-in 2-Series control system enables the DMPS-300-C-AEC to provide complete, customizable control of every AV device, as well as room lighting, window shades, and projection screens, without requiring a separate control processor. The DMPS-300-C-AEC supports the full line of Crestron touch screens, keypads, and wireless remotes for a user experience custom tailored to the specific requirements of each end-user. Support for Crestron control apps and Crestron Fusion® Enterprise Management Software delivers the industry's most powerful platform for remotely controlling and managing multiple rooms using computers and mobile devices.

CEC Embedded Device Control
The primary objective of every Crestron system is to enable precisely the control desired for a seamless user experience. In addition to conventional IR, RS-232, and Ethernet device control, the DMPS-300-C-AEC can provide an additional alternative by harnessing the CEC (Consumer Electronics Control) signal embedded in HDMI. The DMPS-300-C-AEC provides a gateway for controlling many devices right through their HDMI connections, potentially eliminating the need for any dedicated control wires or IR emitters. Through proper CEC signal management, the DMPS-300-C-AEC allows you to take control of each device as you like.

Easy Setup
Every step of the DMPS-300-C-AEC setup process is designed to be quick and easy using its front panel or Crestron Toolbox software, configuring inputs and outputs automatically while letting the installer make intelligent design decisions along the way. Out of the box, the DMPS-300-C-AEC front panel supports basic signal routing for easy testing and troubleshooting during installation. The front panel label strips can be customized using Crestron Engraver software or standard 3/8" tape labels, allowing for the clear designation of each input and output. Inputs and outputs may also be designated by name through the software to appear on the LCD display.
