Crestron MPS-300 Multimedia Presentation System 300
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 three QM inputs. 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 eight 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 (PROG OUT) 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 (REC
OUT) 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 three QM outputs are controlled separately from the other audio outputs,
allowing three different program sources and three different microphone mixes to be
monitored on touchpanels and output to additional audio equipment by way of an
appropriate QM receiver or other QuickMedia device(s).
Built-in Amplifier
A 40-watt amplifier is built into the MPS-300, 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-300 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-300 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.) which are easily entered using the out-of-the-box functionality,
SIMPL™ Windows
® software, or SystemBuilder software.
Easy setup of the MPS-300 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-300 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
