With the Neutrik NA2BBNC-D9B D-shape adapters, connection problems in professional and semi-professional installations are a thing of the past. Their resistant bar-molded aluminum housing offers reliable protection against corrosion, as there are no iron components in it. It reacts only slightly with oxygen and then forms a protective layer. The bayonet locking of the adapter ensures a secure connection even in case of vibrations. In addition, the RCA types are colour-coded for simplified handling.
