Built around a half-DIN chassis, it provides independent control of tower speakers, in-boat speakers, and subwoofers, along with dedicated EQ shaping for both tower and cabin zones.\u003c\/p\u003e\n\u003cp\u003eAt its core, the \u003cstrong\u003eWS-420 SQ\u003c\/strong\u003e features a dual equalizer architecture with two independent 4-band parametric EQ sections. This allows separate tuning for tower and in-boat speaker zones, each offering up to 12 dB of cut or boost per band for detailed system shaping and optimization.\u003c\/p\u003e\n\u003cp\u003eA large master volume knob provides fast overall system control, while separate zone level controls allow users to balance tower, in-boat, and subwoofer output independently. This makes it possible to run multiple listening configurations, including tower-only riding setups, in-boat cruising setups, or full system playback with custom balance between zones.\u003c\/p\u003e\n\u003cp\u003eThe integrated talk-back microphone system enables rider communication by muting tower audio during use and routing voice through the tower speakers as a PA system. Microphone gain is independently adjustable, ensuring clear communication without affecting music levels. Once released, audio resumes at the previous volume setting.\u003c\/p\u003e\n\u003cp\u003eThe WS-420 SQ also includes Wet Sounds Boat Link\u003csup\u003e™\u003c\/sup\u003e functionality, allowing multiple compatible systems to connect via the optional A-Link\u003csup\u003e®\u003c\/sup\u003e Kit for synchronized audio experiences across boats.\u003c\/p\u003e\n\u003cp\u003eAdditional system flexibility includes auxiliary input switching, gain adjustments for input sources, and a 3.5mm auxiliary input for external devices. Illumination settings allow selectable color output, and ground isolation options help eliminate potential alternator noise in complex electrical systems.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e3-zone marine audio controller with integrated 4-band dual EQ\u003c\/li\u003e\n\u003cli\u003eIndependent control of tower, in-boat, and subwoofer zones\u003c\/li\u003e\n\u003cli\u003eSeparate EQ adjustment for tower and in-boat speaker systems\u003c\/li\u003e\n\u003cli\u003eMaster volume control with quick system-wide adjustment\u003c\/li\u003e\n\u003cli\u003eTalk-back microphone with PA functionality through tower speakers\u003c\/li\u003e\n\u003cli\u003eAutomatic music mute during microphone use\u003c\/li\u003e\n\u003cli\u003eAuxiliary 3.5mm input for external audio sources\u003c\/li\u003e\n\u003cli\u003eBoat Link support via optional A-Link Kit for multi-boat audio\u003c\/li\u003e\n\u003cli\u003eInput gain and sensitivity adjustments for system tuning\u003c\/li\u003e\n\u003cli\u003eSelectable illumination settings (blue or red)\u003c\/li\u003e\n\u003cli\u003eGround isolation feature for noise reduction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eA full-featured marine audio control hub designed to deliver precision tuning, flexible zone management, and advanced communication features for high-performance marine sound systems.\u003c\/p\u003e","brand":"Wet Sounds Store","offers":[{"title":"Default Title","offer_id":53342153998615,"sku":"WS-420 SQ","price":399.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0981\/6506\/3959\/files\/420SQ_Front_with_Mic__47339.1658239355.1280.1280.png?v=1779111813","url":"https:\/\/www.wetsounds.com\/products\/ws-420-sq","provider":"Wet Sounds Store","version":"1.0","type":"link"}
