Yep, that's the TASCAM [1] audio connector which is DB-25 and super common in the audio world. Traditional audio uses AES [2] using either XLR or BNC connectors and only carries two audio channels. The TASCAM cable carries far more channels and, if using digital AES, there is no downside since it either works or doesn't.
