Take full control of your marine audio system with the Wet Sounds WS-420 BT Marine Equalizer and Zone Controller. Built on the proven WS-420 platform, the WS-420 BT combines advanced zone management, precision sound tuning, and integrated Bluetooth® streaming in a compact half-DIN format designed for marine and powersports installations.
Engineered specifically for boat and wake environments, the WS-420 BT provides independent control over tower speakers, in-boat speakers, and subwoofer output. This allows users to build completely customizable listening profiles for different on-water scenarios, from cruising to towing to anchored entertainment.
Dual 4-band parametric equalizers enable independent tuning of tower and cabin zones, giving precise control over frequency shaping for each listening area. This ensures optimal clarity, balance, and output regardless of speaker configuration or system size.
The integrated Bluetooth® module provides direct wireless audio streaming, while the system architecture supports seamless switching between sources and zones without interrupting system performance. A large master volume control allows instant system-wide adjustment while maintaining individual zone settings.
For communication behind the boat, the included talk-back microphone enables rider interaction by temporarily muting music and routing voice through the tower speakers. Microphone gain can be independently adjusted for clear communication in varying conditions.
The WS-420 BT is also compatible with the optional Wet Sounds A-Link® system, enabling wireless audio sharing between compatible Wet Sounds systems for synchronized multi-boat playback.
