Reply To: H8000FW: are 1/4 inch in/out jacks balanced when TRS plug is used?

I'm going to assume your db25 adaptor is also lost in space, as this is for AES output.

The 1/4" inputs will accept either a TR mono unbalanced or a TRS balanced or unbalanced. Essentially, the signal is on the T and the R is grounded, so it will unbalance a balanced connection.
