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

The DS-RC4MC is a custom-labeled, four-channel remote control specified for use with the RU-ASX4D and RU-ASX4DR-Stainless. It provides a dedicated remote point for selecting among the four channels managed by the compatible switching system. Custom labeling is part of this product configuration, while the associated setup charge is identified under part number ZCST-LBL. This listing concerns the remote control; audio performance figures supplied in the source data apply to the RU-ASX4D switcher rather than independently to this remote.

Ideal Use Cases

This model is suited to an RU-ASX4D or RU-ASX4DR-Stainless installation that requires four-channel source selection from a remote location. It is particularly relevant when the system uses multiple switching control points or when the operator needs controls labeled for the installation's assigned sources. The compatible RU-ASX4D system switches four stereo, line-level inputs to one stereo output and supports local or remote control. The DS-RC4MC extends that control concept to a purpose-identified remote station.

Why Choose This Model

The primary reason to select the DS-RC4MC is its stated compatibility with both RU-ASX4D and RU-ASX4DR-Stainless systems. Its four-channel format corresponds with the four source inputs handled by the compatible switcher. Custom labeling allows the control position to reflect the intended source assignments instead of relying solely on generic channel identification. Buyers should also account for the separate custom-label setup charge identified by part number ZCST-LBL when planning the complete order.

Installation and Integration

Integration should be planned around the requirements of the selected RU-ASX4D or RU-ASX4DR-Stainless installation. The RU-ASX4D provides local or remote switching and supports multiple control points. Its listed control interface includes four 1 mA source-selection inputs pulled to ground, one 1 mA SEL input pulled to +15 Vdc, and five 25 mA open-collector outputs to ground. The switcher's audio and power connections use detachable terminal blocks, and its stated power requirement is 24 Vdc at 150 mA, ground-referenced. These are switcher specifications; the supplied data does not state the remote control's dimensions, power requirement, mounting method, or wiring details. Those values should therefore remain unspecified rather than being inferred from the host equipment. Custom label requirements and the ZCST-LBL setup charge should be addressed as part of the ordering process.

Performance Highlights

The remote is intended to control source selection within a system whose RU-ASX4D switching stage accommodates balanced or unbalanced stereo line-level inputs and output. Each source has gain trim at the compatible switcher. Listed RU-ASX4D performance includes a 10 Hz to 20 kHz frequency response at ±0.2 dB, THD+N below 0.01% from 20 Hz to 20 kHz, and more than 20 dB of headroom above +4 dBu at unity gain. The switcher also provides greater than 85 dB off attenuation at 1 kHz and crosstalk below -85 dB at 1 kHz. Its balanced output level is +4 dBu, with the unbalanced output 6 dB below the balanced level. These figures describe the compatible audio switcher's signal path and provide context for the system the DS-RC4MC controls.

What Makes It Different

The defining feature of the DS-RC4MC is the combination of four-channel remote operation and custom labeling for the stated compatible models. It is not presented as a general-purpose audio switcher or as a replacement for the RU-ASX4D hardware. Instead, it serves as a project-specific control component for an existing compatible switching architecture. Compatibility with both the RU-ASX4D and its RU-ASX4DR-Stainless counterpart also allows the same listed remote-control option to be considered across either specified system version.

Final Assessment

The DS-RC4MC is a focused choice when an RU-ASX4D or RU-ASX4DR-Stainless system needs a custom-identified, four-channel remote control point. Its value lies in direct model compatibility, alignment with the host system's four-source switching arrangement, and labeling tailored to the installation. Confirm the required label content and include the ZCST-LBL setup charge when applicable. Remote-specific physical, electrical, mounting, and accessory details are not provided in the supplied data.
