4 Channel Remote Control for RACK-UPs

The RDL D-RC4RU is a four-channel remote control designed for single-button selection of four audio sources. Four momentary pushbuttons provide one control per channel, while four red LEDs indicate the selected channel. The unit supports remote selection of balanced audio sources and connects directly to the RDL RU-SX4A through a detachable terminal block. Its focused layout, professional aesthetic appearance, and compatibility with other RDL remote controls make it a practical control interface for RACK-UP systems.

Ideal Use Cases

The D-RC4RU is suited to systems requiring a separate control point for choosing among four audio sources. It is intended for remote selection of balanced audio sources with the RU-SX4A, and it may also directly control the RDL RU-VSX4 Video Switcher. The combination of one dedicated button and one indicator for each channel provides source-selection control and visible channel status at the same location. Its mounting format accommodates projects based on a standard US electrical box or an RDL WB- or SMB-series box.

Why Choose This Model

Each of the four sources receives its own momentary pushbutton, providing a direct selection interface without combining multiple channels under a shared control. Four corresponding red LEDs indicate which channel is selected. This arrangement is particularly relevant when a system requires clearly defined four-source operation, balanced-audio source selection, and visual confirmation from the remote panel. The D-RC4RU is also designed as a companion to other RDL remote controls, allowing it to maintain the professional aesthetic appearance specified for the product line.

Installation and Integration

The D-RC4RU mounts in a standard US electrical box as well as RDL WB- or SMB-series boxes. A cover plate is available separately and is not identified as included with the unit. Connection is made through a detachable terminal block, with direct interfacing supported for the RDL RU-SX4A. Wiring to the RU-SX4A SLAVE terminals uses a 3-pair cable or a 6-conductor cable, giving installers two equivalent conductor descriptions for planning the connection.

The specified power requirement is ground-referenced 24 Vdc at 30 mA. The recommended supply is the RDL PS-24AS for the USA or the PS-24AX for international use. The documented ambient operating range is 0°C to 55°C. The D-RC4RU may also be used to control the RDL RU-VSX4 Video Switcher directly, extending its documented integration beyond the RU-SX4A audio-source application.

Performance Highlights

The supplied specifications focus on control operation, status indication, wiring, and system compatibility. All four selectors are momentary pushbuttons, with one assigned to each channel. Four red LEDs provide corresponding selected-channel indication. The unit supports remote selection of balanced audio sources and uses only three cable pairs, or six conductors, for its remote wiring connection. Its 24 Vdc, 30 mA electrical requirement and 0°C to 55°C operating range provide concrete parameters for power-system and environmental planning.

What Makes It Different

The D-RC4RU combines a precise four-source control layout with direct compatibility for specific RDL switching equipment. Rather than presenting an unspecified general-purpose control interface, it is documented to interface directly with the RU-SX4A and to control the RU-VSX4 Video Switcher directly. Dedicated selection buttons, individual red status indicators, a detachable terminal block, and support for standard electrical-box mounting are all integrated into the same panel. Its companion styling also allows it to be installed alongside other RDL remote controls while retaining a consistent professional appearance.

Final Assessment

For an RDL system that requires remote selection of four balanced audio sources, the D-RC4RU provides the essential controls, channel indication, and documented integration path in one wall-mountable unit. It is especially applicable when direct RU-SX4A interfacing, optional RU-VSX4 control, six-conductor remote wiring, and standard electrical-box mounting are project requirements.
