Are there any balanced electronic X-over's?


I am thinking of going with an active cross over but everything in my system is balanced and I would only do it if I could get a balanced crossover with XLR inputs and outputs. Are there any units like this available? Thanks in advance for any help

Pass Labs has a very functional and affordable balanced/SE unit called the XRV. Nelson Pass has been doing active crossovers for a long time. I believe all the Threshold units were from his mind. Here is the link:

Probably for less money you could get a Marchand just the way you like it. My XM9 2-way (balanced only, 250Hz, 24 db) is sold (so far). The frequency modules are very cheap, if you want to experiment. Go on their site (marchandelec.com) and check them out. I'm enjoying my XM44-3 which came single ended AND balanced. A nice touch.
