The HB 410 ADSP 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 6 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.
