PMA AMPLIFIER SERIES

4.8 - Channel Level Controls (only visible when “Advanced Controls” are activated).
To adjust the gain of an amp channel left-click on the button under the Level heading in the GUI.
This will open up a new window, or form, with a volume slider and text entry field. To execute
an adjustment, left-click-and-hold on the slider (virtual sliding volume control) and drag up or
down to the desired setting. The exact value of the adjustment will appear in the text box above
the slider. Once the target value is reached, release the left mouse button and PMA Manager
software will load the setting into the amp DSP and display the setting in large text on the level
readout.
Note that the change does not take place until you release the moust button.
For precise adjustments, it may be easier to type the desired gain setting directly into the text
box on the gain form. To do this, left-click and drag to highlight ALL the text in the text field,
then release the left mouse button and type in your desired setting. Hit ENTER (RETURN) and
PMA Manager will update the text box, slider and readout, then will load the setting into the DSP.
NOTE: You must hit the ENTER or RETURN key after typing in the text box to execute the change.
Once the desired setting has been entered and confirmed, close the gain slider control by left-
clicking on the CLOSE button at the bottom of the form.
NOTE: The level setting form is modal, that is it will be on top of the main PMA Manager GUI and will
stay there preventing you from working with the main form until you close it by selecting the CLOSE
button.
5 - UPDATE AMPLIFIER MEMORY BUTTON
Once all the settings and programs are correct, use this button to store all the settings, filters and
programs shown in the GUI (and which are therefore running in the DSP) in the on-board amplifier
memory. This will insure that the amp “remembers” the programming when it is powered off and
then powered on again.
This will make the programming persistent
during amp power cycles. Failure to
execute this step will cause the amplifier to boot with the last-saved settings.
To store the settings, left-click on the large “Update Amplifier Memory” button. PMA Manager will
write all the current settings to the non-volatile amplifier memory. A progress bar will display while
this is taking place. PMA Manager is writing a lot of data at this point and the process will take a
mintue or two.
Once all parameters have been written, the progress bar and the Update Amplifer Memory button
will disappear from the GUI, indicating that the amp memory now corresponds to the running DSP
parameters which are shown on the GUI and on the front panel display. The “Channel Modified”
asterisks will disappear from the display. Everyting at this point, is “in-sync”.
6 - STATUS BAR
When PMA Manager is writing parameters to amplifier DSP chip or to amplifier memory, the status
bar will update and amplifier commands will display to the right of the progress bar.
During complex writes, such as loading a speaker program or updating the amp memory, another
status bar will appear on top of the main PMA Manager form indicating overall progress.
