4 Channel Remote Control for RU-ASX4D and RU-ASX4DR -Custom Labeled (See Part # ZCST-LBL for setup charge)

Ideal Use Cases

The RDL D-RC4MC is a custom-labeled four-channel remote control for installations using an RU-ASX4D or RU-ASX4DR audio switcher. It is suited to systems that need source selection from a remote operating position or as part of a layout with multiple switching control points. Within an RU-ASX4D system, the controller supports operation of a switcher that routes four stereo, line-level inputs to one stereo output.

Why Choose This Model

The primary reason to select the D-RC4MC is its combination of four-channel control and custom labeling. The labels can align the controller with the sources used in a specific system, helping identify the available selections at the control location. A setup charge for the custom labeling is referenced separately under part number ZCST-LBL.

The compatible RU-ASX4D provides local or remote switching and supports multiple control points. Its four source inputs include individual gain trim, while its selected-input control output is open-collector to ground. The D-RC4MC is intended to place four-channel remote control within that operating environment without replacing the host switcher.

Installation and Integration

Plan the D-RC4MC as a control component for the RU-ASX4D or RU-ASX4DR rather than as a standalone audio switcher. Audio remains connected to the compatible host unit. On the RU-ASX4D, the four stereo line-level inputs and stereo output use detachable terminal blocks and can operate with balanced or unbalanced audio connections.

Before ordering, define the custom label content and account for the ZCST-LBL setup charge referenced in the product title. The supplied information does not specify the controller’s dimensions, mounting arrangement, wiring connection, power requirements, or included accessories. These details should therefore be confirmed for the intended installation rather than inferred from specifications published for the associated RU-ASX4D.

Performance Highlights

The D-RC4MC is a remote control, so the supplied performance figures describe the compatible RU-ASX4D audio switcher rather than the controller itself. The RU-ASX4D has a stated frequency response of 10 Hz to 20 kHz within ±0.2 dB and THD+N below 0.01% from 20 Hz to 20 kHz. Its maximum input level is +25 dBu, and its balanced output level is +4 dBu.

The host switcher’s published noise is below -85 dB with an input selected and below -95 dB with no input selected, both referenced below +4 dBu. It also provides more than 85 dB off attenuation at 1 kHz and more than 70 dB at 20 kHz. These specifications establish the audio environment in which the remote selection function is used; they are not separate performance claims for the D-RC4MC.

What Makes It Different

The defining feature is the product-specific labeling applied to a four-channel remote control compatible with both RU-ASX4D and RU-ASX4DR models. This distinguishes the D-RC4MC from a controller supplied without the custom-label designation. The separate ZCST-LBL reference also makes the labeling setup charge explicit at the ordering stage.

Final Assessment

The D-RC4MC is a focused choice for an RU-ASX4D or RU-ASX4DR system that requires four-channel remote operation with labels tailored to the installation. Its value lies in compatible source-selection control and custom identification, while audio routing, gain adjustment, metering, and signal performance remain functions of the associated switcher. Buyers should verify the controller-specific installation details that are not included in the supplied source data.
