| Hiss becomes noticable
Hiss is often from gain-staging problems. Nothing broken, just adjusted wrong.
In a simple set-up (short cables, no patch bay), bal or unbal connections makes little difference at line levels.
Are you using powered monitors? A monitor controller or analog preamp?
Chart your analog signal path from PT converter to speaker. You want full output from the D-A converters, then attenuation to desired level at the amp (or powered speaker) input.
Using digital attenuation (low output from D-A converter), and having the amp (or powered speaker) cranked could cause noticeable hiss.
