7.3.2 Manual Control from a Graphics Plate
The primary way to control an equalizer is from a graphics plate. Each equalizer has a GDM or graphic display
module. A sample is shown below in Figure 7.4:
However, you don’t have to use the GDM that came with your equalizer. You can create a custom one tailored to
your specific needs. See Section 3.9 for more information about creating a custom GDM.
The controls on the equalizer GDM are very similar in function to the ones on the control block. They are
described next.
Fig. 7.4 A Sample Equalizer GDM
Level: The level control of each frequency band is located in the upper half of the GDM. They function like
“sliders” on a typical equalizer. Simply use the mouse to drag ({) a control up to increase the level or down to
decrease the level at the specified center.
DSPI: The DSPI or Data Signal Presence Indicator is an LED on the unit which flashes whenever it unit is polled.
The DSPI control is used to force the indicator to stay on as an aid to troubleshooting communication on the Crown
Bus. Once the DSPI control is turned on, the DSPI will remain on continuously even if the control block of another
device is selected. Turning off the DSPI control restores the indicator to its normal function of blinking when a valid
IQ command is received.
Mute: Mutes all audio going through the selected channel of the equalizer.
Flat: Quickly restores the settings of all equalizer Level controls to 0 (zero) dB.
Lock: Locks Channel A and B together. Turning on the Lock control causes the changes made to one channel
to also be sent to the other channel.
