+Never use unbalanced XLR connections with microphone cables, as this would short-circuit any phantom power transmitted over these cables!

3.4 Selecting The Operating Level

With the “Operating Level” switch on the rear of the BEHRINGER MULTICOM PRO you can adjust the internal operating level of the unit. Thus, the MULTICOM PRO can be adapted perfectly to various levels (e.g. both the typical home recording level of -10 dBV and the professional level of +4 dBu). The level meters are referenced automatically to the selected level, i.e. an optimum operating range of the meters will always be ensured.
