Remote Level Controller-Preset Levels-Black

The RDL DB-RLC3 is a black, premium-quality remote panel for pushbutton selection of preset audio levels. It gives an operator four selectable system levels, or a configuration with three levels plus Off, while green LED indication identifies the selection. The controller uses a selectable resistance from the CTRL terminal to ground in four steps and interfaces directly with RDL modules that accept 0 to 10 Vdc, 10 kΩ resistive control, including the cited ST-VCA3 and RU-VCA2. Its compact format and professional aesthetic suit installations where clearly defined choices are preferred over continuous level adjustment.

Ideal Use Cases

The DB-RLC3 is intended for audio systems that need repeatable, limited level choices from a wall-mounted control point. Its four pushbuttons provide access to High, Norm, Low, and Min settings; the Min range can extend to Off. This makes the panel appropriate wherever users should select among established operating levels instead of working with an unrestricted control. Green LEDs give visible indication at the panel. The standard electrical-box mounting format also makes it suitable for installed systems using RDL WB- or SMB-series boxes.

Why Choose This Model

This model combines straightforward operation with individually useful level ranges. High is fixed at 10 kOhm and 0 dB. Norm can be adjusted from -3 dB to -30 dB, Low from -5 dB to -40 dB, and Min from -10 dB through Off. Those ranges allow the system designer to establish distinct choices while presenting the operator with simple pushbutton selection. The black panel, green indications, and premium-quality construction are paired with the professional aesthetic appearance identified for the product. For applications built around compatible RDL modules, its direct resistive-control interface keeps the control method clearly defined.

Installation and Integration

Installation is designed around a standard US electrical box or an RDL WB- or SMB-series box. A cover plate is available separately. Connections are made on a detachable terminal block, supporting panel wiring without a permanently attached lead. The unit requires ground-referenced 24 Vdc at 30 mA. The listed recommended supplies are the PS-24AS for the USA and PS-24AX for international use.

At 4.1 inches high, 1.3 inches wide, and 1.6 inches deep (10.4 x 3.30 x 4.10 cm), the DB-RLC3 is sized as a compact remote panel. Its interface is specified as a direct connection to RDL modules using 0 to 10 Vdc and 10 kΩ resistive control. The product data specifically references the ST-VCA3 and RU-VCA2; compatibility beyond the stated interface should be evaluated against the connected module’s control requirements.

Performance Highlights

The output presents selectable resistance from the CTRL terminal to ground in four steps. At the High position, the control value is 10 kOhm for 0 dB. The three adjustable positions cover broad attenuation ranges: Norm spans -3 dB to -30 dB, Low spans -5 dB to -40 dB, and Min spans -10 dB to Off. This arrangement supports either four selectable audio levels or three levels plus an Off selection, depending on the chosen Min adjustment. Green LED indication accompanies pushbutton selection. The specified ambient operating environment is 0°C to 50°C, defining the listed temperature range for installed operation.

What Makes It Different

Unlike a continuously variable panel, the DB-RLC3 centers operation on a small set of preset choices. That distinction is practical when the intended interaction is selection among system-defined levels. Adjustable Norm, Low, and Min ranges let the installer establish the available steps, while High retains its specified 0 dB setting. The panel brings selection, indication, and professional appearance together in one black wall-mount format. Engineering support data listed for the model includes a PDF datasheet, American DXF functional-block CAD information, and American DXF front and rear panel diagrams.

Final Assessment

The DB-RLC3 is a focused choice for compatible RDL audio systems requiring pushbutton access to preset levels. Its four-step resistive output, specified attenuation ranges, green LED indication, detachable terminal block, and standard-box mounting define both its function and installation needs. With 24 Vdc operation at 30 mA and direct 0 to 10 Vdc, 10 kΩ control integration, it provides a documented route to remote level selection through four available positions.
