RDL DB-RC4ST – Four-Channel Remote Control for ST-SX4 Audio Switcher

The RDL DB-RC4ST is a wall-mounted remote control panel designed to operate the RDL ST-SX4 audio switcher. It enables selection of one of four unbalanced audio sources from a single control location, making it ideal for professional AV installations.

The front panel features four momentary pushbuttons, each corresponding to a source input. Adjacent LEDs indicate the currently selected source. Upon power-up, source 1 is automatically selected. Pressing any other button deselects source 1 and activates the chosen input.

The DB-RC4ST connects to the ST-SX4 via the POWER and CTRL terminals using either a 3-conductor cable or a single shielded pair. For stereo setups, the SLAVE output of one ST-SX4 can drive the CTRL input of a second unit.

Built with a steel frame, the electronics are securely housed in the rear enclosure. Connections are made via a detachable rear terminal block.
