How would one drop levels down or raise them up with the 4I/O? I'm not seeing any knobs to adjust levels like on some of the eurorack pedal interfaces.

It doesn't use them. Instead, the 4I/O is a bit more "automatic"; all voltages are constrained to the AE's "operating window" of 0 - +5V. For additional gain inside the AE environment, you'd then use the 2SIGNALAMP to get more level, and on the "outside" you'd just need to turn down your effects' gain, since the voltage difference between the AE standard and typical line level isn't as potentially extreme as in other modular formats.
