Crestron QM-AE 

 

QuickMedia™ Audio Extractor

 

The trim band inputs adjust the gains of the graphic EQ filters. The gains are 
adjustable within a range of -12dB to +12dB. Valid analog values range from  
-120 (-12dB) to +120 (+12dB). 2-Series symbols such as the Analog Scaler with 
I/O Limits and Analog Ramp (Bounds Limited) are capable of handling range 
and sign mapping. 

A trim band value of 0 (0dB) means that the signal will pass unaffected. Values 
above and below 0 will boost or reduce the gain in increments of .1dB. That is, 
changing the analog value by 1 signifies a boost or attenuation of 0.1 decibels. 

All save and recall inputs are level sensitive. Thus when <SaveTrimPreset> is 
driven high, the ten trim band values will be saved in the indicated 
<TrimPreset#>. Valid values for <TrimPreset#> range from 1 to 10. 

Similarly, when <RecallTrimPreset> is driven high, the values stored in 
<TrimPreset#> will be recalled and immediately propagated to the outputs. 
Here the program left, right, and microphone trim band feedback signals may 
have different values than their corresponding inputs. 

In addition to the 10 trim presets, the QM-AE provides five filter presets, where 
a filter preset is a set of 12 filters. A filter consists of the center frequency, gain, 
bandwidth and filter type (EQ, high/low pass, treble/bass shelf) for each of the 
three outputs channels. These values are only settable using DMT software. 

When <RecallFilterPreset> goes high and remains high, the current filter 
values stored in <FilterPreset#> (as set in the SystemBuilder software) will be 
recalled and applied to the outputs. Valid values for <FilterPreset#> range from 
1 to 5. 

An example program for the QM-AE is available from the “Example Program” 
section of the Crestron website (http://www.crestron.com/exampleprograms).  

 

NOTE:  Crestron recommends that you use the latest software and that each 
device contains the latest firmware to take advantage of the most recently 
released features. Please check the Crestron website 
(http://www.crestron.com/updates) for the latest versions of software and 
firmware. New users are required to register to obtain access to this site. 

Assuming a PC is properly connected to the entire system, Crestron 
programming software allows the programmer to upload programs, projects and 
firmware to the system and touchpanels after their development. However, there 
are times when the files for the program and projects are compiled and not 
uploaded. Instead, compiled files may be distributed from programmers to 
installers, from Crestron to dealers, etc. Even firmware upgrades are available 
from the Crestron website as new features are developed after product releases. 
In those instances, one has the option to upload via the programming software or 
to upload and upgrade via the Crestron Toolbox.  

The following sections define how one would upload a SIMPL Windows 
program to the control system or upgrade the firmware of the QM-AE. 
However, before attempting to upload or upgrade, it is necessary to establish 
communications.
