APSUB-CH41
AmpPRO PC App
Use of the AmpPRO PC App
allows you to do the following:
• Configure User Interface Options such as:
• Minimum Volume Level
• Enable / Disable Factory EQ
• Set Bass Center Frequencies and Q Factor
• Update Product Firmware
• Read Firmware / Hardware Versions
• You can download the AmpPRO app at :
https://pac-audio.com/app-downloads/
PLEASE NOTE: These settings can be adjusted with the module installed in the vehicle, or on the bench. However, it is
recommended to make the adjustments with the module installed, and the factory radio on, so that the changes can be
heard.
Minimum Volume Level - This allows you to set the minimum volume level of the factory radio (factory radio volume level 1).
EQ Enabled - This allows you to enable / disable the bass band factory EQ from adjusting the APSUB output.
Bass Freq / Q Factor - This allows you to set the center frequency that will be adjusted when setting the bass band on the
factory EQ, as well as the Q Factor for the frequency. The Q Factor determines how many of the adjacent frequencies will be
affected when adjusting the selected frequency. The lower the Q Factor, the more frequencies will be affected. See below for
available frequencies and Q Factors. Note: This setting only affects the output of the APSUB and does not change the way that
the factory EQ adjusts the factory speakers.
