4 Channel Remote Control for RACK-Ups-Black

The RDL DB-RC4RU is a four-channel remote control designed for selecting among four audio sources. Each source has its own momentary pushbutton, giving the operator a direct, single-button selection method rather than a multi-step control sequence. Four red LEDs identify the selected channel. The unit supports remote selection of balanced audio sources and is designed to interface directly with the RDL RU-SX4A.

Ideal Use Cases

This model is suited to systems that need a dedicated control point for four-source selection while the associated RDL switching equipment is installed elsewhere. It fits applications where operators benefit from one clearly assigned button for each source, visible channel status, and a professional aesthetic that can sit alongside other RDL remote controls. It can also be used to control the RDL RU-VSX4 Video Switcher directly, making it applicable where the specified RDL video switcher is part of the system.

Why Choose This Model

The DB-RC4RU focuses on a specific control task and keeps the interface concise. Four selectors correspond to four channels, and each selector has a red LED status indicator. This direct relationship between source, button, and indicator supports fast recognition of the active selection. The detachable terminal block simplifies the physical interface to system wiring, while documented compatibility with the RU-SX4A establishes the intended companion switcher. Its professional appearance and compatibility with other RDL remote controls help maintain a consistent control surface.

Installation and Integration

Installation uses a 3-pair cable, or a six-conductor cable, connected to the SLAVE terminals of the RU-SX4A. The listed connection is a detachable terminal block, and the unit interfaces directly with the RU-SX4A. For installations built around the RU-VSX4 Video Switcher, the DB-RC4RU may also provide direct control. Power must be ground-referenced 24 Vdc at 30 mA. RDL lists the PS-24AS as the recommended power supply for the USA and the PS-24AX for international use.

For physical mounting, the control 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 a complete installation. The stated ambient operating range is 0° C to 55° C. These details allow the mounting box, cable, power supply, and cover plate to be planned before installation.

Performance Highlights

Operation is based on four momentary pushbuttons, one for each channel. Pressing the assigned control provides single-button source selection, while the corresponding red LED provides channel-selected indication. The remote is specified for balanced audio-source selection and uses three cable pairs, or six conductors, for remote wiring. Its 24 Vdc, 30 mA power requirement defines the electrical needs clearly, and its 0° C to 55° C ambient specification establishes the stated operating environment.

What Makes It Different

Unlike a generic multifunction panel, this model is explicitly arranged around four control positions: four buttons and four indicators for four sources. It is a companion to other RDL remote controls and is designed with a professional aesthetic. Direct interfacing with the RU-SX4A is part of its connection specification, and direct control of the RU-VSX4 is also identified. The combination of balanced-audio source selection, detachable terminal-block wiring, and standard electrical-box mounting gives system designers a defined integration path without adding functions not required for four-channel selection.

Final Assessment

The RDL DB-RC4RU is a focused choice when a system requires remote, single-button selection of four balanced audio sources with visible LED confirmation. Its value is strongest in installations using the RU-SX4A or RU-VSX4, where compatibility and wiring requirements are already specified. With four momentary controls, four red indicators, 3-pair or six-conductor wiring, standard-box mounting, and a 24 Vdc at 30 mA requirement, it provides a clearly documented remote-control interface for the intended RDL switching system.
