The APM series is a complete, audio system with control interfaces and signal processing. The application range from active louderspeaker concepts (digital 3 way 3 unit, 2 way 2 unit crossover, bass enhancement, etc.) and realize the tansformation from 2.0 to 2.1. With four potentiometers, customers can get the default function and adjust the gain, cut-off frequency of bass and treble.

With integrated debug port for Sigima Studio, customers can pre-program with Sure Electronics ICP1, ICP2 or the original Analog USBi to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics

processing, delay compensation, etc.

Hi, how meny hz is the crossover

Hi, helge. Sorry for the late reply. The preset frequency range of DSP is as follows and you can adjust within the range through the potentiometers on the board or the APP with our ICP3. High-pass Filter: 250Hz-2kHz Band-pass Filter: 60Hz-120Hz(High-pass); 200Hz-400Hz(Low-pass) If you program through SigmaStudio, you can adjust the cut-off frequency to your speakers' condition and your requirements within 20Hz-20kHz. Please be noticed that once the program you write is uploaded to the DSP, original program will be covered.

Hi, what is the acceptable voltage range on pin 10 (J1) labeled VIN?

Dear Anton, Sorry for the late reply. J1 of the DSP is used to connect with the Extension Kit. We do not suggest that you use it for other use.
