I'm thinking of separating the preamp from the rest of the system. (I want
to keep the preamp in front of the listening position, but I'd rather get
the amps and processor boxes out of the way.) The preamp is line level with
unbalanced outputs, and the receiver is an active crossover which has
balanced inputs. Would an unbalanced interconnect, say 10m long, be likely
to have a problem?

The main amp may have a potentially balanced input, but you're
unbalancing it :-)

A professional audio setup wouldn't dream of using an unbalanced
connection, especially of this length. They have to KNOW the
connection won't get noisy, even if a new piece of equipment is added.
But the audiophile world is only loosely connected to the pro-audio
world :-) I imagine once set up, your setup will stay as it is? Try.
If it hums get a box to balance the preamp output.
