Links - buffered 2:2 section?

Hi :wave:, I understand that the 2:2 section of Links may be used as a 1:2 multiple. Is it buffered (like the 1:3 section) or passive? Thanks!

It is an active circuit, and the output signal doesn’t change whether only one, or both outputs are connected. “Buffer” would be a strange word for a circuit capable of adding without amplitude loss!
