Herman # RDLRC4ST

This item has been discontinued.



The RC4‑ST is a wall‑box mounted remote module designed to directly control an RDL ST‑SX4 Audio Switcher Module. The ST‑SX4 provides solid‑state switching of one of four unbalanced audio inputs to a single unbalanced audio output. The RC4‑ST connects directly to the POWER and CTRL terminals of the ST‑SX4 using either a 3‑conductor cable or a single shielded pair.

The front panel of the RC4‑ST features four pushbuttons with four associated LEDs. Upon initial application of power, source 1 is selected. Touching any of the other three 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. For stereo installations, the SLAVE output from the ST‑SX4 is used to drive the CTRL input of an additional ST‑SX4.
