RDL D-RC4ST Series 4-Channel Remote Control for ST-SX4 4x1 Audio Switcher

Deliver precise, professional audio control for conference rooms, control centers and security monitoring stations with the Radio Design Labs RDL D-RC4ST 4-Channel Remote Control. This wall-box mounted remote control module is designed specifically to pair with the ST-SX4 audio switcher, giving AV integrators and IT teams an easy, low-profile interface for selecting one of four unbalanced inputs via solid-state switching. The four push-buttons and corresponding LEDs offer intuitive, immediate visual confirmation for users, reducing mistakes during live meetings, surveillance monitoring or mission-critical broadcasts. Wiring is straightforward — connect to the ST-SX4 power and control terminals using a 3-conductor cable or a single shielded pair — and stereo installations are supported by using the ST-SX4 slave output. Built for reliability in commercial AV, security and video conferencing environments, the D-RC4ST streamlines audio routing while maintaining low noise and long-term performance. Ideal for video conference controllers, monitoring rooms and integrated security systems — specify the RDL D-RC4ST for your next installation or contact us for ordering and integration support.
