The Bittree B48DC-FNSSH/E3 M2OU7L has a spacious 2x24 jack configuration with mono (even) jack spacing. With selectable normalling and grounding circuits can be easily changed via shunts under both designation strips. Patchbays with switched grounds feature an additional switching contact in every jack. Grounds are lifted when patching, ensuring a proper grounding scheme is maintained, and ground loops, or earth loops, are avoided.
