Remote Channel Selector-4 Channels-controls RU-ASX4D/R -Custom Labeled (See Part # ZCST-LBL for setup charge)

The RDL D-RCS4C is a custom-labeled, four-channel remote channel selector specified for control of an RU-ASX4D/R audio switching system. It gives users a dedicated point for choosing among four channels while keeping the associated switching unit positioned where the system design requires. This listing covers the remote selector rather than the RU-ASX4D audio switching hardware itself. Custom labeling is included in the product configuration, with the related setup charge referenced separately under part number ZCST-LBL.

Ideal Use Cases

The D-RCS4C is suited to installations that require selection among four channels from a location separate from the associated RU-ASX4D/R. It is especially relevant when generic channel numbering would not communicate enough information to the user. Custom labels allow the available selections to be identified according to the source names used in the installation.

Within the associated switching system, the RU-ASX4D handles four stereo, line-level inputs and routes the selected source to one stereo output. The switcher supports multiple switching control points as well as local or remote operation. This makes the D-RCS4C appropriate when the system design calls for a clearly identified remote selection position without relocating the central audio connections.

Why Choose This Model

The defining combination is straightforward: four-channel selection, compatibility with the specified RU-ASX4D/R, and custom labeling. The channel count corresponds to the four source inputs handled by the associated switching unit, creating a focused control surface for source selection. Custom labels can make each choice immediately recognizable rather than requiring users to interpret channel numbers or consult a separate reference.

The D-RCS4C should be selected when those three requirements are already established. It is not presented as a standalone audio switcher, and the available source data does not specify compatibility with equipment beyond the RU-ASX4D/R named in this listing.

Installation and Integration

Plan the D-RCS4C as the remote selection component of an RU-ASX4D/R system. The associated RU-ASX4D provides local and remote controlled switching, four source-selection control inputs, and open-collector control outputs that indicate the selected input. Its audio inputs, stereo output, and power connection use detachable terminal blocks. The RU-ASX4D requires 24 Vdc at 150 mA with a ground-referenced supply.

Before ordering, determine the exact custom text and channel order required for the installation. The product title directs purchasers to part number ZCST-LBL for the custom-label setup charge, so that charge should be accounted for when configuring the order. Cable requirements, mounting dimensions, supplied accessories, and installation hardware for the D-RCS4C are not identified in the provided data.

Performance Highlights

The D-RCS4C performs the selection role; the published audio performance figures belong to the associated RU-ASX4D switching unit. That switcher supports balanced or unbalanced stereo line-level inputs and output, with rear-panel gain trim for every source. Its specified frequency response is 10 Hz to 20 kHz at ±0.2 dB, while THD+N is below 0.01% from 20 Hz to 20 kHz. Maximum input level is +25 dBu, and headroom above +4 dBu is greater than 20 dB at unity gain.

The RU-ASX4D is also specified for greater than 85 dB off attenuation at 1 kHz and greater than 70 dB at 20 kHz. Crosstalk is below -85 dB at 1 kHz and below -65 dB at 20 kHz. These specifications describe the host audio path and should not be interpreted as separate audio circuitry inside the D-RCS4C.

What Makes It Different

This model is distinguished by its custom-labeled configuration. A standard four-channel selector identifies positions numerically, while this listing explicitly provides for labeling tailored to the intended system. That distinction is valuable where the selector must communicate the identity of each available source directly at the control point.

Its purpose is also tightly defined. The D-RCS4C is listed specifically to control the RU-ASX4D/R, avoiding the ambiguity of a general-purpose control panel. The four available selections align with the associated switcher’s four stereo inputs, and the setup-charge reference makes the custom-order requirement visible before purchase.

Final Assessment

Choose the RDL D-RCS4C when an RU-ASX4D/R installation requires a remote, four-channel selector with channel names customized for the project. It combines a clearly bounded control function with labeling tailored to the available sources. For accurate ordering, specify the required label text and include the ZCST-LBL setup charge referenced in the product title. Applications requiring standalone audio switching or compatibility with another host model should use a product with those capabilities explicitly documented.
