Remote Channel Selector-4 Channels-controls RU-ASX4D/R

The RDL D-RCS4 is a premium remote source selection panel designed to control the RDL RU-SX4A audio selector. Four channel-selection controls provide remote access to the selector, while five front-panel LED indicators communicate the current selection state. A green LED identifies each of the four selected channels, and a red LED indicates that no channel is selected. The panel supports multiple control and indication locations and presents the professional aesthetic appearance specified for the model.

Ideal Use Cases

The D-RCS4 is intended for audio systems that require source selection from a location separate from the associated RDL selector module. It is particularly applicable when users need a straightforward panel for choosing among four channels while receiving immediate visual confirmation of the active source. Support for multiple control and indication locations also makes the panel suitable for installations where selection status must be accessible from more than one position.

Because the controls and indicators are presented on a dedicated remote panel, the D-RCS4 provides a focused interface for source selection without exposing unrelated system controls. The red no-selection indicator also makes it clear when none of the four channels is active.

Why Choose This Model

The D-RCS4 combines four-channel remote selection with a five-LED status display. Each channel has a green selection indicator, giving the operator a direct visual reference to the selected source. When no source is selected, the separate red LED provides an unambiguous status indication.

The panel uses a pushbutton-actuated SEL output rated at 15 Vdc and 5 mA. Its LED inputs are activated by grounding and can connect directly from the RDL selector module. These defined control and indication interfaces make the panel purpose-built for integration with the associated RDL selection system. The source information also identifies the D-RCS4 as a premium-quality remote panel with a professional aesthetic appearance.

Installation and Integration

The D-RCS4 mounts in a US electrical box or in RDL WB-1U and WB-2U international wall boxes. A decorative plate is available separately, allowing the mounting assembly to be completed according to the installation requirements. Electrical connections are made through a detachable terminal block, which provides a removable connection point for control, indication, and power wiring.

The panel requires ground-referenced 24 Vdc at 25 mA. The recommended power supply is the PS-24AS for the USA or the PS-24AX for international applications; the power supply is not included. Installers should account for this separate power requirement when specifying the complete system.

Manufacturer data identifies direct connection from the RDL selector module for the grounding-activated LED inputs. The SEL output is generated through pushbutton actuation. Front and rear panel diagrams are available in American DXF format, along with CAD information that includes an engineering functional block in American DXF format.

• Grounding-activated LED inputs with direct connection from the RDL selector module.
• Pushbutton-actuated SEL output rated at 15 Vdc and 5 mA.
• Ground-referenced 24 Vdc operation at 25 mA.
• Specified ambient operating range of 0° C to 55° C.
• Detachable terminal-block connections.

What Makes It Different

The D-RCS4 is not simply a four-button control surface. Its indication system distinguishes between every selected channel and the absence of a selection. Four green LEDs provide channel-specific feedback, while the separate red LED communicates the no-channel state. This five-indicator arrangement gives the operator both selection control and visible confirmation from the same panel.

Its compatibility with standard US electrical boxes and RDL international wall boxes provides defined mounting paths for different installations. The combination of detachable terminal connections, documented control signals, separately available decorative plates, and downloadable technical resources supports planned system integration.

Final Assessment

The RDL D-RCS4 is a dedicated four-channel remote source selection panel for the RU-SX4A audio selector. It offers clear channel and no-selection indication, supports multiple control and indication locations, and provides defined electrical interfaces through a detachable terminal block. For systems requiring remote four-source selection in a premium-quality panel with a professional appearance, the D-RCS4 delivers the specified controls, status feedback, and mounting compatibility in a focused design.
