Using H9 as Line Level Processor

[nickrose]

Two issues:

1) H9 is designed for guitar level, so a hot line level will probably overload it. Note that people talk about "line level" as if it is a clearly defined thing, but in practise there is a wide range – +4dBu is probably a nominal level – peaks may be much higher.

2) H9's inputs and outputs are unbalanced. You can connect it to a balanced input or output if your connections unbalance the input(output) – this often happens automatically.

At the end of the day, do what makes sense. If it clips, drop the level. If it hums, you are probably not unbalancing it properly. Or you have a dread ground loop.

I want to use my H9 as a line level processor. I understand from the manual that you can input line level as long as you keep the signal below +4dBu. I plan using the H9 through a balanced patchbay.

First, what issues if any do I need to consider patching between the balanced patchbay and the H9? For example, should I use a balanced or unbalanced patch cable?

Second, would it be significantly better, i.e., less headache and much better signal, to go the extra mile and add Line to Instrument boxes between the balanced patchbay and the H9?

Finally, if using Line to Instrument boxes, do I use balanced or unbalanced patch cables between the patchbay and the Line to Instrument boxes?

Thanks for any help.
