Crestron MPS-250 Multimedia Presentation System 250
The MPS-250 ships with the Volume Control Mode set to the Master Vol. setting.
When switching the Volume Control Mode from the Master Vol. setting to either
the Program Only setting, the Speech Only setting, or the user selectable
Pgm/Spch Sel. setting, the Minimum and Maximum Volume levels for the
SPEECH and PROGRAM outputs must be set to ensure proper operation.
• Set the Volume Control Mode to Program Only, Speech Only, or
Pgm/Spch Sel. as described on page 46.
• Set the PROGRAM output’s Minimum and Maximum Volume levels to
30% and 70% (respectively) as described in the instructions on page 40.
• Set the SPEECH output’s Minimum and Maximum Volume levels to 30%
and 70% (respectively) as described on page 47.
• Set the Startup Volume levels for the PROGRAM and SPEECH outputs
to 30% as described on pages 42 and 49.
• Set the Master Startup Volume to 100% to obtain the maximum dynamic
range for the installation. Refer to the instructions on page 53.
• Raise or lower the Startup Volume levels for the PROGRAM and
SPEECH outputs as necessary. These levels will determine the volume
level of the system each time it is turned on.
If the Volume Control Mode is to be returned to the Master Vol. setting from the
Program Only setting, the Speech Only setting, or the user selectable Pgm/Spch
Sel. setting, the Minimum and Maximum Volume levels for the SPEECH and
PROGRAM outputs must be set to ensure proper operation.
• Set the Volume Control Mode to Master Vol. as described on page 46.
• Set the PROGRAM output’s Minimum and Maximum Volume levels to
30% and 70% (respectively) as described in the instructions on page 40.
• Set the SPEECH output’s Minimum and Maximum Volume levels to 30%
and 70% (respectively) as described below and on the following page.
• Set the Startup Volume levels of the “loudest” outputs (PROGRAM or
SPEECH) to 100% as described on pages 42 and 49 so maximum dynamic
range is available.
• Set the Master Startup Volume to the desired level (will probably be less
than 50%). Refer to the instructions on page 53.
Set the Speech Minimum
Volume The Speech Minimum Volume control is used to set the lowest volume setting of the
SPEECH output. The RECORD and PROGRAM outputs are not affected by
changes made to the Speech Minimum Volume level.
To set the Speech Minimum Volume level:
• Access the Speech Output menu as described on page 43.
• Press the k or j buttons until “Min Volume” is displayed on the LCD and
press ENTER to open the Speech Minimum Volume controls.
