4 Channel Remote Control for ST-SX4-stainless steel

Ideal Use Cases

The RDL DS-RC4ST is a stainless-steel remote control for installations requiring remote selection of four unbalanced audio sources through an RDL ST-SX4. It provides a dedicated control point with one button for each source, making it suitable wherever source selection needs to be accessible away from the ST-SX4 itself.

The unit mounts in a standard US electrical box or an RDL WB- or SMB-series box. This mounting format, combined with its professional aesthetic appearance, makes the DS-RC4ST appropriate for permanently installed audio systems that call for an integrated wall-mounted control. A cover plate is available separately.

Why Choose This Model

Four momentary pushbuttons give the operator direct, single-button access to all four channels. Each source has its own button, so no menu navigation or repeated stepping through channels is required. Four red LED indicators identify the selected channel and provide a clear visual reference at the remote control location.

The DS-RC4ST interfaces directly with the RDL ST-SX4 through a detachable terminal block. Its focused design combines source selection, channel indication, and remote wiring support in a single control. It is also presented as a companion to other RDL remote controls, which can help maintain a consistent professional appearance across an RDL-based installation.

Installation and Integration

The control supports 3-conductor remote wiring to the ST-SX4. The supplied technical information also identifies connection to the ST-SX4 control terminals using either a 3-conductor cable or a single shielded pair. A detachable terminal block provides the specified connection interface between the remote and the ST-SX4.

Power requirements are ground-referenced 24 Vdc at 30 mA. The recommended power supply is the RDL PS-24AS for USA applications or the PS-24AX for international applications. These requirements should be considered when planning the control wiring and power arrangement.

For mounting, the DS-RC4ST fits a standard US electrical box as well as RDL WB- or SMB-series boxes. The cover plate is available separately, allowing the installer to select the appropriate plate for the installation. The published ambient operating range is 0 degrees C to 55 degrees C.

Performance Highlights

The DS-RC4ST provides remote control over four unbalanced audio sources connected through the ST-SX4. Its four momentary selectors correspond directly to the four available channels. Pressing the button assigned to a source makes that channel selection, while the associated red LED indicates which channel is selected.

This direct control arrangement keeps the operating interface centered on the essential task of choosing a source. The separate indicator for every channel gives the user immediate selection status without relying on labeling alone. The control requires only 30 mA from a ground-referenced 24 Vdc supply.

What Makes It Different

The DS-RC4ST is specifically designed to interface with the RDL ST-SX4 rather than serving as a general-purpose standalone source selector. Its combination of four single-purpose pushbuttons, four channel-status LEDs, and direct ST-SX4 connectivity gives it a clearly defined role within the source-selection system.

The stainless-steel model also addresses the visible side of an installed control system with the professional aesthetic appearance identified for the product. Support for standard electrical-box mounting and RDL enclosure options provides multiple specified installation paths, while the detachable terminal block supports system connection and servicing.

Final Assessment

The RDL DS-RC4ST is a focused remote-selection interface for an ST-SX4 handling four unbalanced audio sources. Its strongest attributes are the one-button-per-source layout, individual red channel indicators, direct terminal-block interface, and support for 3-conductor remote wiring.

For an installation already centered on the RDL ST-SX4, this model supplies the matching four-channel remote control in a stainless-steel format. Confirm the required mounting box, separately available cover plate, ground-referenced 24 Vdc power arrangement, and applicable PS-24AS or PS-24AX supply when specifying the complete installation.
