HARMONY DSP 4+‎

The Harmony DSP App allows you to setup and tune your system with your smart phone or tablet.
In the main screen you will find the Input Source menu where you can choose BT, HI-LEV, USB and AUX. Here you also find 8 Presets (saved into your device) to choose from, you access the Music Player, you have the Main and Subwoofer Volume, and the Advanced menu with Channels, EQ, System and Mixing.
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). From the App it is possible to access the folders and the contained audio files.
