DSP management by bt app (iOS/ Android) :  

1. CONFIGURATOR mode Mainly it’ll allow the DSP tuning. You can manage every DSP functon through your smartphone/ tablet/PC/MAC.

2. DRC mode The BT device becomes a remote control by using the dedicated app with a simple graphical user interface. Manage volume level, SUB level, select different setup files, upload a new setup file.
Setup file sharing via bt    Upload a setup file via BT through the BT APP when in “Configurator” or “DRC” mode.
DSP management by pc / mac / ios / android    Microsoft Windows (32/64 bit): Windows 10 (USB and BT BLE) Windows 11 (USB and BT BLE) Mac Os: 10.13 Hight Sierra or later (USB and BT BLE)
