Description
The DS-RC4ST is a wall-box mounted remote control panel designed to operate an RDL ST-SX4 audio switcher. It provides four momentary pushbuttons and LED indicators that show the currently selected unbalanced audio source. The unit is intended to be mounted in a standard US electrical box and presents a professional stainless steel front.
The front panel includes four pushbuttons and four red LEDs, one LED per button, to indicate the selected source. On power-up the unit selects source 1 by default and the LEDs reflect the active selection. Buttons are momentary and immediately switch the connected ST-SX4 to the corresponding input when pressed.
Control connections are made to the ST-SX4 POWER and CTRL terminals using a three-conductor cable or a single shielded pair as required. The DS-RC4ST interfaces directly with the ST-SX4 control inputs and can be daisy-chained using the SLAVE output on the ST-SX4 for stereo installations. Power is ground-referenced 24 Vdc as specified for the ST-SX4 control circuit.
The remote is optimized for unbalanced audio selection and offers a clean user interface for source switching in installed systems. Wiring requirements are minimal and the control signals are solid-state through the ST-SX4 switcher module. The red LED indicators provide clear visual feedback of the active source at a glance.
Typical applications include small presentation rooms, background music zones, and AV racks where wall-mounted source selection is needed. It is suitable where one ST-SX4 module controls one output and where a second ST-SX4 can be added for stereo by using the SLAVE/CTRL chaining method. The stainless steel finish matches common faceplate aesthetics in commercial installations.
Installation is straightforward and follows standard low-voltage control wiring practices. The DS-RC4ST mounts in standard US electrical boxes or compatible RDL WB or SMB series boxes and accepts optional cover plates. The unit is built for reliable operation in commercial ambient conditions and presents a professional appearance for installed AV systems.
