From the Channel Page, you can assign the function of each speaker, check the Phase for polarity, adjust the individual Channel Gains and set Delay in milliseconds or centimeters, for a rock solid and accurate front stage. The EQ page holds the heart and the brains of the App. You can use either the Graphic or the Paragraphic EQ’s. You can customize the crossovers to fit the needs of your individual system. You have adjustments for Gain, frequency, and Q factor. You can work on channels individually or you can link them. With the MIX function you can manually determine which inputs (USB-L/R, Digital-L/R, BT-L/R) will be used for each output (processing channel) and how much of each input the output will receive. The new Music Player function lets you have full control of all your favorite songs, inside the App. Be sure to connect a proper USB device containing audio files in the supported format (MP2/4, WMA, APE, FLAC, AAC, M4A,WAV, AIF, AIFC).
