Wet Sounds WS-420BT — Marine Multi-Zone 4-Band Parametric Equalizer with Integrated Bluetooth

The Wet Sounds WS-420BT is a marine 3-zone equalizer and controller with integrated Bluetooth, featuring two independent 4-band parametric equalizers for separate tower and cabin zone control. Built on the award-winning WS-420 platform, the WS-420BT gives you complete control over your marine audio system — including independent volume control for tower speakers, in-boat speakers, and subwoofer — all in a half-DIN chassis. Includes a talk back microphone for rider communication.

The WS-420BT is Wet Sounds’ flagship marine audio controller — a 3-zone equalizer built on the award-winning WS-420 platform that has set the benchmark for marine audio system control. If you’re running a serious audio setup on your boat with tower speakers, in-boat speakers, and a subwoofer, the WS-420BT gives you the level of control and flexibility needed to get the most out of every component in your system.

At its core, the WS-420BT features two completely independent 4-band parametric equalizers — one for the tower zone and one for the cabin zone — allowing you to tune each part of your system separately for optimal sound at any speed or volume. Independent volume controls for tower speakers, in-boat speakers, and subwoofer mean you can dial in exactly the mix you want, then use the large master volume knob for quick overall adjustment. Run tower and subwoofer only, in-boat and subwoofer only, or all zones together — the WS-420BT handles any combination.

Integrated Bluetooth® connectivity allows wireless audio streaming directly to the system, alongside a 3.5mm auxiliary input and main input for additional source options. The included talk back microphone connects to the tower speakers for rider communication — when the microphone is keyed, the music mutes automatically for announcements, then resumes at the previous level when released. Microphone volume is independent from music level for easy adjustment.

For multi-boat setups, the optional Wet Sounds A-Link Kit (sold separately) allows you to share audio wirelessly between multiple Wet Sounds equipped systems. Built for the marine environment with a conformal coated board and high-performance Japanese operational amplifiers, the WS-420BT is designed to handle years of on-water use without compromise.
