RNC is the more transparent one, RNLA was introduced as a squashier/less transparent version. I have an RNC. They work really well.
The sidechain input is a little unconventional. It has an insert style where it outputs a mono mix of the inputs on the tip and takes the key input back on the ring. Which means you can run an insert Y-cable with an inline passive HPF to take the bass out of the sidechain signal to stop it overreacting to the kick. Lets you compress a house/techno mix buss quite hard in a live situation.
