What up, I'm hear for some help because I'm just getting to confused reading various threads. Here's my situation ! I have a Saffire Pro 40 and was looking into buying one or to channel strips or preamps. Preferably an Avalon VT?737 and maybe a Great River or a Grace 101. Unsure of that yet, but my question is, what is my best option to hook these up to the Pro 40.? I've read threads about using the Pro 40's line inputs and setting it to unity gain which is about 4-5. Than I read threads that say your better off getting an external converter and wiring the pre's into that. However, how does that work? I know you hook the converter up to the Pro 40 via ADAT, but than what? In all reality, whats the best way to wire an avalon to the pro 40 or any other preamps/outboard gear? This is with setting price aside. Should I get an external converter or sell the Pro 40 and look into another interface that is suitable for what I'm looking to do. Any help, recommendations, or advice is much appreciated.
