4 Channel Remote Control for ST-SX4-Black

The RDL DB-RC4ST is a four-channel remote control designed to interface directly with the RDL ST-SX4. It provides remote selection of four unbalanced audio sources from a professional control point. Four momentary pushbuttons, one assigned to each channel, make individual source selection straightforward. Four red LEDs indicate which channel is selected. The controller uses 3-conductor remote wiring and connects through a detachable terminal block.

Ideal Use Cases

The DB-RC4ST is suited to ST-SX4 installations that require source selection from a separate control location. Its four-button arrangement is appropriate when an operator needs dedicated access to each of the four available audio sources. Because each source has its own momentary pushbutton and selection indicator, the interface presents all four choices together rather than requiring a multipurpose selector. Its professional aesthetic appearance also makes it appropriate for installations where the remote control will remain visible. The model can be used alongside other RDL remote controls when a coordinated control arrangement is required.

Why Choose This Model

This model combines a defined ST-SX4 interface with an uncomplicated one-button-per-channel control layout. A red LED for each channel identifies the current selection, providing immediate visual confirmation at the remote location. The four selectors are momentary pushbuttons, so each channel has a consistent physical control. Compatibility is explicitly centered on the RDL ST-SX4, and the detachable terminal block provides the specified connection point. For systems already based on the ST-SX4, these characteristics provide a purpose-specific remote-selection interface rather than an unspecified general control panel.

Installation and Integration

The DB-RC4ST mounts in a standard US electrical box or in RDL WB- or SMB-series boxes. A cover plate is available separately, so it should be accounted for when planning the finished installation. The detachable terminal block interfaces directly with the RDL ST-SX4, while the documented 3-conductor remote wiring keeps the required control cabling clearly defined. The unit requires ground-referenced 24 Vdc power at 30 mA. The recommended power supplies are the RDL PS-24AS for the USA and PS-24AX for international installations. Its specified ambient operating range is 0° C to 55° C. These mounting, wiring, power, and environmental requirements should be confirmed against the planned electrical box, RDL enclosure, and installation location before deployment.

Performance Highlights

• Remote selection of four unbalanced audio sources
• Four momentary pushbuttons, with one selector for each channel
• Four red LEDs that indicate the selected channel
• Direct interface with the RDL ST-SX4 through a detachable terminal block
• 3-conductor remote wiring
• Ground-referenced 24 Vdc operation at 30 mA
• Specified operation from 0° C to 55° C

The performance emphasis is focused on source-selection control: every channel receives both a dedicated pushbutton and a dedicated red selection indicator. This gives the operator a compact view of the four available choices and the selected channel.

What Makes It Different

The DB-RC4ST is distinguished by its direct relationship with the ST-SX4 and its balanced set of four selectors and four indicators. The control count corresponds directly to the ST-SX4’s four source choices, creating a clearly organized front-panel arrangement. Its installation flexibility is also notable: it can be fitted to a standard US electrical box or selected RDL WB- and SMB-series boxes. The professional appearance and compatibility with other RDL remote controls allow it to serve as part of a broader RDL control layout while retaining its dedicated four-source function.

Final Assessment

For an RDL ST-SX4 installation requiring remote control of four unbalanced audio sources, the DB-RC4ST provides the specified selectors, channel indicators, wiring interface, and mounting support in one focused model. Its four momentary buttons and four red LEDs keep selection status visible, while the detachable terminal block and documented 3-conductor wiring support direct integration. Installers should plan for ground-referenced 24 Vdc power, a compatible electrical box or RDL enclosure, and the separately available cover plate.
