What is the DB25 Input on the back panel of the RMB-1075 and RMB-1095 used for?
The 25-pin DB25 input on the RMB-1075 and RMB-1095 offers an alternative connection for the input signal rather than using the standard RCA inputs. The signal quality is comparable for either connection method, the main advantage of the DB25 being the convenience of connecting a single cable as opposed to five separate RCA cables. While Rotel does not manufacture cables, many audio cable manufacturers carry or can construct an RCA-to-DB25 cable for this purpose. For those wishing to wire their own DB25 cable, Rotel provides the pin configuration for this cable below.
