Two DB-15 connectors allow for remote control of other audio gear. The Remote B connector holds the start and stop pulses for stereo inputs one through seven. The Remote A connector is home to speaker muting relays and external remote mic and telco channel muting. The external meter socket feeds line (0VU at 0dBu) program left and right levels to an audio meter via a DB-9 connector. The 12 configuration dipswitches on the back of the mixer allow for setting up different on/off button options.

Using unbalanced RCA jacks for connection to control room speakers and an external monitor source can be viewed in two ways: Cost effectiveness on the part of the manufacturer, and/or end-user usability. In the case of the XB-14, providing options for users to interconnect with prosumer grade audio equipment is paramount. Additionally, for example, small powered speakers almost always have unbalanced inputs, and nearly every FM or AM receiver has RCA jacks. In that regard, the XB-14 is a friendly and forward-thinking product. In providing USB in/out, remote interfacing, telephone hybrid ins and outs, and a beautiful mix of unbalanced and balanced ins and outs, the XB-14 will easily find a home where multiple applications and close attention to the budget are necessary.
