Reference Voltages
The Behringer CP35 module is hungry for rack space (21HP !) but a lot of people only need the 6V voltage references.
So, from an idea by LEK Productions, here is a compact (4HP) module containing just +6V and -6V voltage references. Three different build options are available depending on how accurate you want the reference voltages to be.
