Universal signal convertor & ground isolator
The Apart BUZZSTOP-MKIII is a universal input adaptor that can be used for all connections and extensions. The input level selector allows you to convert any amplifier output to any line-level output, balanced or unbalanced. (E.g.: You can convert a 100V loudspeaker signal into a balanced or unbalanced line level signal). The BUZZSTOPMKIII also makes it possible to convert an unbalanced signal into balanced and vice versa.
