Remote Level Controller-Preset Levels

The RDL D-RLC3 is a premium remote panel for selecting preset audio levels from a dedicated wall control. Its pushbutton interface offers four selectable system levels, or three levels plus an off setting, while green LED indication provides visible feedback. The panel connects directly with compatible RDL modules through 0 to 10 Vdc, 10 kΩ resistive control, giving an audio system a clearly defined set of level choices rather than continuously variable adjustment.

Ideal Use Cases

The D-RLC3 is suited to audio installations that require convenient remote selection among predetermined volume levels. It can provide four available settings for systems that need a consistent range of audio levels. Alternatively, its minimum setting can be configured as off, creating three active levels plus an off position. Its narrow panel dimensions and compatibility with standard US electrical boxes make it appropriate for a permanent wall-mounted control location.

Direct compatibility with RDL modules using the specified control interface makes the panel particularly relevant when integrating an ST-VCA3 or RU-VCA2. Pushbutton operation provides a straightforward way to move between the configured High, Norm, Low, and Min selections.

Why Choose This Model

The principal advantage of the D-RLC3 is its combination of preset control, visible indication, and installation-oriented construction. Each selection corresponds to a defined resistance step from the CTRL terminal to ground. The High setting is fixed at 10 kΩ and 0 dB. Norm is adjustable from -3 dB to -30 dB, Low is adjustable from -5 dB to -40 dB, and Min is adjustable from -10 dB through off.

These adjustment ranges allow the installer to establish distinct choices appropriate to the connected system. Once configured, the front-panel pushbuttons provide access to those choices without requiring adjustment of the underlying RDL module. The premium-quality remote panel and professional aesthetic appearance also make it suitable for visible installation locations.

Installation and Integration

The D-RLC3 mounts in a standard US electrical box or in compatible RDL WB- or SMB-series boxes. A cover plate is available separately. The panel measures 4.11 inches high, 1.66 inches wide, and 1.72 inches deep. Metric dimensions are listed as 10.44 cm high, 4.06 cm wide, and 4.37 cm deep.

Electrical connections are made through a detachable terminal block. The interface uses a direct connection with RDL modules supporting 0 to 10 Vdc, 10 kΩ resistive control. Its output provides selectable resistance from the CTRL terminal to ground in four steps. Power must be ground-referenced 24 Vdc at 30 mA. The recommended power supplies are the PS-24AS for the USA and the PS-24AX for international use.

The specified ambient operating range is 0°C to 55°C. These mounting, connection, power, and environmental requirements should be considered when selecting the electrical box, associated RDL module, power supply, and installation location.

Performance Highlights

Four-step level selection is the central performance feature of the D-RLC3. The available attenuation ranges provide separation among the Norm, Low, and Min positions, while the High position delivers the defined 0 dB setting. Configuring Min through off allows the same controller to function either as a four-level selector or as a three-level selector with an off choice.

Green LED indication supplements the pushbutton controls with a visible panel indication. The combination of fixed selection positions and installer-adjustable level ranges gives the system defined operating choices while retaining configuration flexibility at installation.

What Makes It Different

Unlike a continuously variable remote level control, the D-RLC3 focuses on deliberate selection among four preset steps. This approach keeps the available choices tied to configured High, Norm, Low, and Min values. The option to turn the Min position into an off command extends that arrangement without adding a separate control.

The model also combines its control function with a compact, professional panel format. Direct RDL module connectivity, a detachable terminal block, standard electrical-box mounting, and compatibility with RDL mounting boxes provide a clearly specified path for integration.

Final Assessment

The RDL D-RLC3 is a focused solution for remote preset audio-level selection. It provides four pushbutton-selectable settings, or three levels plus off, with green LED indication and adjustable attenuation ranges for the Norm, Low, and Min positions. Its 0 to 10 Vdc, 10 kΩ resistive interface, 24 Vdc power requirement, detachable terminal block, and standard-box mounting support structured integration with compatible RDL equipment. For systems that need defined level choices from a premium wall panel, the D-RLC3 supplies the necessary control and installation features in a compact format.
