Use of the AmpPRO App allows
you to do the following:
• Congure User Interface Options such
as:

frequencies and Q factor

PLEASE NOTE: These settings can be adjusted with the module installed in the vehicle, or on the bench. However, it is
recomended 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)
Chime Volume Level - This allows you to set the volume of the AP4 chimes (ie: park sensors).
Front / Rear Chimes Enabled - This allows you to enable/disable AP4 chimes (ie: park sensors). This is used when mixing
factory and aftermarket speakers.
3 Band EQ Enabled - This allows you to enable / disable the 3 band factory EQ.
Bass / Mid / Treble Freq / Q Factor - This allows you to set the center frequency that will be adjusted when setting the 3 band
factory EQ, as well as the Q Factor for each 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.
