More details on the Wet Sounds Light Sync 4

Product Research


Overview: The Wet Sounds WS-4Z-RGB is a 4-zone controller for LED lights for your boat or RV. It was co-developed by Wet Sounds and Shadow-Caster, a manufacturer of under water and above water boat lights. With the WS-4Z-RGB, you can control four separate zones, either individually or simultaneously. You can change the color and brightness of the lights, or set the lights to "dance" to music. The kit includes the 3.5" diameter controller with mounting hardware and an 18" wiring harness.

Light Controller: The controller is made with a UV-stabilized polycarbonate cover with a stainless steel bezel, and a machined aluminum rear housing. It can be installed in a standard 3" gauge opening. The controller's 16 backlit silicone buttons can perform the following commands:

  • All / Off: One press of the All button turns on the controller. Pressing it again returns all connected lights to the previous setting. The Off button turns off the lights in all zones, or, if preceded by a zone number, turns off the designated zone.
  • 1, 2, 3, 4: Buttons are provided for each of the four lighting zones. The backlighting of the button will match the selected color and mode of that zone.
  • White, Red, Green, Blue: Buttons are provided for the available colors of lights. Pressing and releasing a color button will turn on the lights at full intensity. Pressing and holding a color button will cause the lights to fade up from black and stop when the button is released.
  • <, >, ˅, ˄: Left/right and up/down arrow buttons can shift the color hue, sync the lights with music, strobe the lights, or fade the lights.

Wiring: The included wiring harness has a 26-pin Molex connector that plugs into the back of the controller. The harness has the following wires:

  • Zones: Four sets of three 18" RGB (red/green/blue) wires run to four individual lighting zones.
  • Power/Ground: 18" Red/white and Black/white wires connect to +12VDC power source and ground.
  • Shadow-NET: 18" Orange and yellow wires are for connecting the controller to an optional Shadow-caster PD Plus power distribution box.
  • Audio Input: This 40" cable has a female 3.5mm audio input for connecting the controller to your system's head unit. With this audio input, you can sync the lights with the tempo of the music you're playing.
