With a bit of extra income coming in from multiple sources, I'm really considering taking the dive, but i have some concerns. I'm thinking about getting basically the AE modular starter rack 1, rehoused in their 16u eurorack adapter, with a few changes and putting that in a Tiptop Audio Mantis for future expansion, along with an Arturia Keystep. I understand that the AE system is limited to 0-5 volts on CV, is it also limited to 0-5 volts in it's audio signal? I don't want to plug in my guitar or, say, a line of One sample players and blow up my AE system. If it is limited to 0-5 for Audio, what would I do to step down levels simply? Would I use a VCA? Is an audio signal's voltage the same as it's amplitude? like instrument level vs line level vs modular level?
