Professional Audio DSP
Each analog audio output on the DMPS-100/200/300-C 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-100/200/300-C 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
multizone loudspeaker system.
EDID Format Management
The DMPS-100/200/300-C 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-100/200/300-C 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
and DM-
RMC-SCALER-C (both sold separately), the DMPS-100/200/300-C 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 and Blu-ray Disc™ releases 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 simply
stops 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.
