I would like to get a patchbay to make patch changes easier in my rack. Im looking at the Beringher px2000 or px1000. What is the difference between Balanced and Unbalanced? (the PX2000 is unbalanced.) All my cables are 1/4" mono plugs for routing around the various boxes. Some times I do voice through the same rack. Any help appreciated on the above or even a recommendation as to which one to get. the px2000 is only $49 new so thats why im looking at it. Thank you for any tips.
