Remote Level Controller-Preset Levels-stainless steel

The RDL DS-RLC3 is a stainless-steel remote level controller designed for pushbutton selection of preset audio levels. It provides four selectable system levels or can be configured for three levels plus off. Green LED indication identifies the selected setting, while the premium-quality remote panel presents a professional appearance for installed audio systems. The controller interfaces directly with compatible RDL modules through 0 to 10 Vdc, 10 kΩ resistive control.

Ideal Use Cases

The DS-RLC3 is suited to installed audio systems that require users to select among established volume settings instead of making continuous level adjustments. Its HIGH, NORM, LOW, and MIN selections provide clearly defined operating choices for systems where preset levels are preferred. The MIN setting can be adjusted down to off, allowing the controller to operate with four selectable levels or three levels plus an off selection. Green LED indication provides visible confirmation at the panel.

Its mounting format supports installation in a standard US electrical box as well as RDL WB- or SMB-series boxes. These options make the controller applicable to wall-mounted control locations where a compact remote panel and direct access to preset audio settings are required.

Why Choose This Model

This model combines pushbutton operation with configurable preset ranges. HIGH is specified at 10 kOhm 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 to off. These ranges allow the system installer to establish distinct selections appropriate to the connected audio system while leaving straightforward controls for the user.

The stainless-steel format, green status indication, and professional aesthetic distinguish the DS-RLC3 as an installation-oriented control panel. A detachable terminal block supports the required wiring connections.

Installation and Integration

The DS-RLC3 connects directly with RDL modules that use a 0 to 10 Vdc, 10 kΩ resistive control interface. The supplied interface specification references the RDL ST-VCA3 and RU-VCA2 as examples. At its CTRL terminal, the controller provides selectable resistance to ground in four steps. This electrical arrangement enables the four pushbuttons to select the configured system levels.

Power must be ground-referenced 24 Vdc at 30 mA. The recommended power supplies are the RDL PS-24AS for the USA and PS-24AX for international use. Wiring is made through a detachable terminal block. The controller mounts in a standard US electrical box or in an RDL WB- or SMB-series box. A cover plate is available separately.

The panel measures 4.1 inches high by 1.3 inches wide by 1.6 inches deep, equivalent to 10.4 by 3.30 by 4.10 cm. Its specified ambient operating range is 0°C to 50°C.

Performance Highlights

The four-step output gives each pushbutton a defined resistance setting at the CTRL terminal. The fixed HIGH selection corresponds to 10 kOhm and 0 dB, while the other three selections provide installer-adjustable attenuation ranges. NORM covers -3 dB through -30 dB, LOW covers -5 dB through -40 dB, and MIN covers -10 dB through off.

This arrangement provides access to one high setting and progressively lower selectable settings. When MIN is adjusted to off, the same panel supplies three active audio levels plus an off selection. Green LEDs provide indication of the selected level.

What Makes It Different

Rather than presenting a continuously variable control, the DS-RLC3 centers operation on four labeled pushbutton selections. The adjustable NORM, LOW, and MIN ranges let installers define the lower operating levels, while HIGH remains specified at 0 dB. This balance of fixed user selections and installer-adjustable settings is the model’s defining control approach.

The direct RDL control interface, detachable terminal block, electrical-box mounting compatibility, compact dimensions, and stainless-steel presentation are combined in one remote panel. Engineering resources listed for the model include a PDF datasheet, an American DXF engineering functional block, and American DXF front and rear panel diagrams.

Final Assessment

The RDL DS-RLC3 is a focused solution for remote selection of preset audio levels in compatible installed systems. It offers four pushbutton choices, configurable attenuation ranges, an optional off selection through the MIN setting, and green LED indication. With 24 Vdc operation, direct 0 to 10 Vdc resistive-control integration, and support for standard US electrical-box or RDL box mounting, its specifications are clearly aligned with professional audio control installations.
