How do I tell, see, check, confirm firmware version on Sound Devices 552?


What is the current firmware on my Sound Devices 552? How do I find the firmware version on my 552? This is maybe not as obvious an answer as you might wish. SVEN will not tell you. The answer isn’t in the manual, but it is on the end of this video from the Sound Devices website. The answer is, the last two lights of the power up display tell the tale. The left channel LED place number is the most significant bit, the right channel LED place number is the least significant bit. This picture indicates firmware version 1.4
