I have a Fredenstein Bento 2, holding 2 external preamps that I would like to connect to the Studio 192. If I understand things correctly, inputs 3-8 on the 192 bypass the preamps when a TRS connection is used.

The Bento 2 has balanced outputs (XLR or TRS), but AFAIK the TRS inputs of the 192 are mono.

Any advice on how to connect these?

Thanks!
