RAIL 24V

The RAIL 24V is a combined lighting and audio system from KSCAPE, the architectural brand within the K-Array group. Built on a 1190 mm extruded aluminium profile, it integrates LED illumination with a three-transducer audio array in a single slim unit, designed for workplaces, residential, and commercial installations where both light and sound must share the same ceiling or wall plane.

Applications

The RAIL 24V suits open-plan offices, meeting rooms, retail stores, hotel lobbies, and residential living areas where a single ceiling fixture must provide both functional illumination and distributed background audio. Multiple optical configurations are available: Symmetric for corporate environments, Asymmetric for museum or gallery wall-washing, Diffused for hospitality interiors, and Electrified Track for projector integration. An indirect optic can be added for suspended installations. The audio system is powered by a K-Array amplifier such as the KA-14 or KA28, which provide cloud-based control and DSP presets.

Frequently asked questions

What amplifier does the RAIL 24V audio system require?
The audio section is driven by a K-Array amplifier such as the KA-14 or KA28. These provide the necessary DSP presets and cloud-based control functions for the integrated transducer array.

What lighting control protocols does the RAIL 24V support?
It supports standard 24 V DC on/off switching, DALI digital dimming, and Casambi Bluetooth wireless control. The LED driver is a remote electronic unit ordered separately from the fixture.

Is the remote LED driver included with the RAIL 24V?
No. The electronic remote driver is ordered separately. The fixture body includes the LED module, aluminium profile, audio transducers, and connectors, but the driver unit is specified and purchased independently.
