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.
CAUTION: IT IS NOT RECOMMENDED TO ADJUST THE GAIN SETTINGS OF AMP CHANNELS
CONNECTED TO DRIVERS WITHIN A MULTI-WAY SPEAKER SYSTEM RELATIVE TO ONE AN-
OTHER. THE RELATIVE LEVELS OF LOUDSPEAKER DRIVERS WITHIN A SPEAKER SYSTEM ARE
CAREFULLY OPT MI ZED DURING PRODUCT DESIGN AND ANY CHANGE TO THESE LEVELS
WILL ALTER THE ACCURACY THE REPRODUCED SOUND - THE VERY REASON FOR WHICH
YOU SELECTED A PRO LOUDSPEAKER IN THE FIRST PLACE!
DON’T DO IT!
STEP 6 : STORE DSP PARAMETERS IN AMPLIFIER MEMORY
This is the most important step, as failure to complete it will cause you to lose all your settings if
the amp is powered off.
Once the settings for all installed channels have been set in the software GUI (and therefore
transferred to the running DSP chip), the settings must be stored in the amplifier memory so they
can be reloaded the next time the amp is powered on. If they are not stored into memory, next
time the amp power is cycled, the previously stored settings will load into the DSP.
Carefully inspect all settings for the connected amp in the GUI. In particular make sure that driv-
ers within a multi-way speaker are routed to the same analog input. Make sure that woofer driv-
ers are connected to the correct low-frequency (LF) speaker programs and that high-frequency
drivers are connected to the correct (HF) programs. Check that the correct compensation filters
(if any) are loaded into the channels of the correct drivers. For example, screen compensation
should be applied only to HF drivers; room boundary compensation only to LF drivers, etc.
When you’re convinced that everything is correct, left-click the full-width “UPDATE AMP MEMO-
RY” button that appears just under the controls in the GUI. PMA Manager will write all settings to
the amp non-volatile memory so that they can be loaded every time the amp powers on. A prog-
ress bar will appear indicating the status of this process. Once completed, the progress bar will
close and the UPDATE AMP MEMORY button and asterisks on the front panel display will disap-
pear indicating that the settings in the DSP have been successfully written to AMP memory.
