The WS-420SQ Equalizer is a state of the art equalizer designed to provide amazing control and flexibility of your marine audio system. The WS-420SQ is 3 Zone equalizer/controller with 2 separate equalizers in one half din chassis using our exclusive design which allows you to independently control the volume of tower speakers, in boat speakers and subwoofers all independently and have EQ adjustments of both in boat and tower speakers independently. The WS-420SQ is the world’s only true marine audio zone controller/equalizer. The Wet Sounds talk back microphone allows the boat driver to communicate with the rider or other boats in the area. By pushing the button on the microphone, the system will automatically mute the music playing from the tower speakers and allow you to use your tower speakers as a PA system. Once the button is released, the tower speakers will begin to play again at the level they were at. Additionally, the WS-420SQ includes Wet Sounds exclusive Boat Link™. Boat Link gives you the ability to link up with other WS 420SQ equipped boats for the ultimate party cove experience.
