Handmade in Great Britain. Standard voltage version - you will need to check your average mains voltage to make sure it is not excessive (over 245v). If you don't have a voltage meter we can send you a small plug-in version. If your average mains voltage is over 245v, you will need our bespoke voltage model.


Normal mains is single ended. By changing this to balanced you remove noise and distortion. The BMU plugs in the mains wall socket and acts as a distribution box to four separate sockets mounted on the top of the unit; these can be used in the same way as any mains socket.
