Adjusting the QM-FTDC Microphone Inputs
Once a QM-FTDC is installed and configured, settings for gain, gating level,
attack time, and decay time should be set using the SystemBuilder finish tab.
NOTE: Crestron recommends that you use the latest software to take advantage
of the most recently released features. The latest software is available from the
Crestron website.
Definitions
The QM-FTDC allows for adjustments to be made to microphone input signals.
The following are definitions of terms that are commonly used when making
adjustments.
Attack Time
The time it takes (in milliseconds) from when an input signal rises above the
gating level until the microphone output signal is enabled.
Clipping
A condition in which a signal level exceeds the maximum level (the clipping
level) a circuit can handle. This is usually caused by improper gating parameters
and gain settings.
Decay Time
The time (in milliseconds) from when an input signal falls below the gating
level until the microphone output signal is muted.

DESCRIPTION
Indicates that the FlipTop cover is fully open.
The feedback remains high for as long as the
cover is open.
If the cover is not fully open the signal will go
low, the keypad buttons will be disabled and
the unit will not report any button presses.
High/1 = FlipTop open;
Low/0 = FlipTop not fully open
Sets the levels that will be displayed on the
left bargraph. The bargraph is an 8-segment
LED and is proportional to the input.
Valid values range from 0% to 100%.
Sets the levels that will be displayed on the
right bargraph. The bargraph is an 8-segment
LED and is proportional to the input.
Valid values range from 0% to 100%.
