I’ve never used that particular pedal personally but the spec on their website says its dynamic range is +8dBu, a form of measurement that is outside of my level of expertise although it seems eurorack is classed at +13dBu, apparently.
What I do when I send a modular signal into something supposed to take a much lower level is simply start fully attenuated and then bring it up bit by bit, then stop before it clips. If you start bringing the levels up beyond that clipping range is when you’re at a risk of damaging the equipment.
If you don’t feel like you know what you’re doing, just get an interface module, they mean you have to think about this a whole lot less.
