You can indeed build an adapter to use the unbalanced inputs/outputs with balanced connectors. However, please note that this doesn't mean you will be benefited from the advantage of balanced connections (ex. better noise rejection, higher output power). An unbalanced to Balanced conversion is also prone to grounding issues (ground loops). We strongly recommend for that matter to either use an active converter or isolation transformer adaptor. 

This case scenario usually happens with users that have an amp with only balanced inputs. If you are looking for a processor that has balanced outputs, you might want to consider the 4x10HD or the SHD.
