The Bittree B96DC-HNSST/ID M2OU7B is a front selectable TT (Bantam) 969s Series audio patchbay in 2RU with high-density 2x48 jack configuration with mono (even) jack spacing. 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.
