Question How can I get my BH250 / BG250-208 amp in update mode  Answer On the BH250 and the BG250-208, you have a small hole called "UTIL" at the back just below the Speakon Connector. On the BG250-208 It is not very easy to access it without disconnecting the speaker connector. Use a paper clip to press the small button inside the hole while powering on the unit. Once this is done, the amp will be ready to receive the update.  The updates can be found below:  BH250 software update BG250-208 software update IMPORTANT: make sure to download the software update that matches your amp. Do not load a BH250 software on a BG250-208.(and vice versa).
