What kind of scenario would require long cable runs for an RNC? Why wouldn't you keep it pretty close to the mixer?

Just a hunch, but wouldn't the parts to do such a mod come close to the cost of a new RNC anyway?

What will it take?

Two Jensen transformers would do it. Talk to Jensen to see which transformers would do the job. http://www.jensentransformers.com

2? Isn´t 4 requiered for balanced stereo in+out?

Yep, my bad.

Check out the November 2000 issue of Recording which describes how to make a cable using an inexpensive transformer for coverting unbalanced to balanced.

mats,
How many transformers needed will be dictated by what signal you send to the RNC and what signal you need to have coming out. Depends on your output from the board. Can you send an unbalanced signal from an aux or insert or secondary main out? Are ya gonna use it as a sub bus compressor, main bus compressor or insert? Just some thoughts...

Lundahl makes some high quality converters with built-in transformers. See http://www.lundahl.se/catframe.html
under category 'problem solvers'.

Depending on your application, you may only need to balance the inputs in order to get common mode rejection.

The input transformer will allow common mode rejection and avoid unbalancing the output of sensitive balanced gear.

An unbalanced output feeding the appropriate level into and expecting the correct impedance from a balanced input should sound fine. And the inoput transformer down the line will still do common mode rejection even if the signal isn't differentially balanced.

In this way, perhaps you only need 2 transformers?

...or...you could just wait a month or 3 for the "RNMP" (Really Nice Mic Pre) which is going to act as a 'balance box' for the RNC as well as acting as a mic-pre...
