I'm hooking up an lc-1, and since it's an older one I'm told I can use a resistor to protect against voltage spikes, and it won't affect the input voltage if the efilive analog input is high impedence (like around 1 meg.). So need to know if this is the case. I have efilive v1. (It will be a 1K resistor between the lc-1 analog out and the efilive analog in.)
