Ruth's sister 12-24V Semi Touch Music Controller Internal Power Cable

Semi-Touch Music Controller

The Ruth's sister 12-24V Semi Touch Music Controller is an internal power cable designed to manage LED lighting strips and modules via a 2.4 GHz radio frequency remote. It suits PC builders and hobbyists who want synchronised light effects driven by an audio source without external noise interference. The unit operates on a wide 12 V to 24 V input range and delivers up to 432 W across three output channels with two channels in parallel. A 3.5 mm audio input enables music-reactive modes for immersive ambient lighting.

Build Quality and Connectors

The controller measures 105 mm by 86 mm by 28 mm and weighs 220 g, while the remote measures 115 mm by 55 mm by 20 mm for handheld operation. Advanced PWM technology provides fine lighting transitions across 20 classic modes and 15 music change modes, all selectable from the semi-touch remote. Dual-channel RGB output increases drive capability for larger installations, and a memory storage function retains the last settings after power loss. The wide operating temperature span of -20 °C to 60 °C supports use inside warm chassis environments.

Compatibility Checklist

Verify that your power supply delivers 12 V or 24 V DC to match the controller's input voltage range before ordering. Confirm that the LED strips or modules you intend to connect do not exceed the maximum output current per channel. Ensure there is physical space for the 105 mm by 86 mm controller board and that a 3.5 mm audio source is available if music modes are desired. The 2.4 GHz remote requires line-of-sight or close proximity, so plan the mounting location accordingly.
