Possible manufacture date of Studio Konnekt 48 audio interface

New

Hello guys,


Could somebody help me to find out the possible manufacture date of Konnekt 48 device I've purchased recently? Its Serial Number is (21) 10070257 and TC Item Number is 967300051. Another interested detail that OPTO and ADAT toslink ports have different design, OPTO ones have no covers, but ADAT ones have doors. I've attached a photo of the internals as well (can provide more, if needed).


Thanks,
Vitalii
