Crestron MPS-250 Multimedia Presentation System 250
Professional Audio Features Five stereo audio inputs on the rear panel accept balanced or unbalanced line-level
signals from computers and other program audio sources. Additional audio sources
can be brought in through the QM input. To accommodate a wide range of signals,
adjustable input compensation is employed to help maintain consistent volume levels
when switching between sources. Versatile matrix mixing allows the selected
program signal and the four microphone signals to be separated or mixed in any
combination to feed three “local” outputs, each with its own unique mix.
Three discrete balanced line level outputs are provided, each with independent
adjustments for volume, bass, treble, and mute. The stereo PROGRAM and mono
SPEECH outputs are normally intended for driving external amplification, with
relay muting on each output to prevent “thumping” on power up. The RECORD
output allows for a completely separate stereo mix to feed a codec, recording device,
or assistive listening system. Ten-band graphic equalization plus 2-band parametric
equalization on each output eliminates the need for expensive outboard audio
processors, and up to 40ms delay adjustment is available on the SPEECH output for
proper loudspeaker alignment.
The QM touchpanel output is controlled separately from the other audio outputs,
allowing a different program source and microphone mix to be monitored on the
touchpanel, or output to other audio equipment by way of an appropriate QM
receiver or other QuickMedia device.
Built-in Amplifier A 40-watt amplifier is built into the MPS-250, with three models available offering
the choice of 8-ohm stereo, 70V mono, or 100V mono outputs. For large rooms
requiring more power, the MPS-250 supports plug-and-play compatibility with
Crestron's QM-Series 3-channel amplifiers, providing a complete solution for driving
a professional loudspeaker system with discrete program and speech channels.
Front Panel Control Out of the box, the MPS-250 front panel supports easy pushbutton routing of input
sources to each of the outputs, and audio volume adjustment using the volume
control knob. Dedicated buttons and indicators are also provided for separate control
of system power and projector power. In addition, five preset buttons are included
for custom functions such as lowering a projection screen, closing blinds, or
selecting a lighting preset.
The front panel label strips are easily customized using Crestron Engraver software
or standard 3/8” tape labels, allowing for the clear designation of each input, output,
and preset button. When selected, these functions will also appear on the LCD
display as generic names (Input 1, 2…), or as custom names (DVD, Podium PC,
Screen Up, etc.).
Easy setup of the MPS-250 is facilitated through the LCD display without
necessitating a computer. Together with four softkey buttons, four menu navigation
buttons and the volume knob, the LCD enables configuration of IP network, audio,
and other system settings. For security, the front panel controls can be password
protected or locked out.
2- Series Control System Integrated into the MPS-250 is a Crestron 2-Series Ethernet control system complete
with e-Control®2 Web server and a host of RS-232, IR, digital input and relay
control ports for integration with third-party equipment. Anything from a basic AV
