Anybody here terminate DH Labs BL-1 cable?

I want to make sure I'm terminating these correctly.
They have 2 conductors, a drain wire and a shield.

For unbalanced RCA termination, 1 wire for signal, 1 wire for ground, and combine the drain on the ground wire?
Is that correct? Or is the drain only used for balanced connections?

Thanks,
Itsik
