The RC4*RU is a wall*box mounted remote module designed to directly control an RDL RU*SX4A Audio Switcher Module. The RU*SX4A provides solid state switching of one of four balanced/unbalanced audio inputs to a single balanced/ unbalanced audio output. The RC4*RU connects directly to the power and SLAVE terminals of the RU*SX4A using a 3*pair cable (or a 6*conductor cable). The RC4*RU may be used to directly control the RDL RU*VSX4 Video Switcher. The front panel of the RC4*RU features four pushbuttons with four associated LEDs. Upon initial application of power, source 1 is selected. Touching any of the other 3 buttons de*selects source 1 and immediately selects the source corresponding to the button pushed. An LED adjacent to each button shows which source is selected. There are 4 output terminals on the RC4*RU. Each of these is an open*collector output, which is pulled to ground when the output is selected. For stereo installations, the RC4*RU is capable of driving two RU*SX4As simultaneously.
