You must install a switch per drawing above at each headphone station if you want both stereo AND monaural capability. If a monaural headphone is to be used, switch that station to MONO mode. If you don't, the entire system will not operate properly and a warning tone may sound. Switches and mounting plates for six(6) stations are included with the 403 and 403d
