APPLICATION NOTE POPPING ISSUE WHEN THE UNIT IS SWITCHED ON THE FIRST TIME by Stan Blleszynski, Bryston, 4-DEC-2020 1) Examine the "automut" parameters which governs the timing involving muting/unmuting related to a 'popping' issues (2): a) Using RS232 Termite: #30GETDautomut [ ends line and sends the command!] b) Using TCP/IP WebGui Terminal window: %2330GETDautomut. This command should return a value greater than 1, the standard default is 5 (in units of 0.1s) 2) If the value is 0 or 1 then it should be reinitialzed by running the "default EEPROM" command sequence: #30INIT00 [reinitializes user EEPROM configuration, takes 1s] or from the TCPIP: %2330INIT00. 3) Alternatively you can redefault all memory to FACTORY DEFAULT (EEPROM and FLASH) which is: #30INIT222 [unlocks the special commands] #30INITfa [reinitializes all FLASH and EEPROM configuration, takes 30s (*)] or from TCPIP: %2330INIT222. %2330INITfa. Note(*): INIT00 is safer to use, INITfa may also reset USB MASS STORAGE FLASH2, which stores "vol=255" parameter for the BDA3 so if you do this command on the BDA3 then you need to manually set it to "vol=255" afterwards. Setting the "vol" parameter is not necessary for BDA3.14 . Note (2): another related parameter is "hdmute" which governs mute/unmute related to HDMI source switching and play/pause. Stan B.
