MCR-1 Marine Gauge Stereo Receiver – Big Sound, Small Footprint

Whether you're cruising across the lake, tackling off-road trails, or anchored at a quiet cove, the Edge Audio MCR-1 delivers reliable, high-quality marine audio in a compact gauge-style design. Engineered for 12V DC electrical systems (negative ground), this waterproof digital media receiver fits seamlessly into standard 3-inch gauge openings—making it the perfect upgrade for boats, jet skis, ATVs, UTVs, Jeeps, golf carts, and other outdoor vehicles where space is limited.

Despite its small size, the MCR-1 packs powerful features. Stream music wirelessly via Bluetooth, plug in a USB drive to play MP3/WMA files, connect external devices through the rear AUX-IN (R/L), or tune into your favorite AM/FM stations with auto-store presets. The large rotary knob gives you easy control over power, volume, and mute, while dedicated buttons allow quick access to track selection, source switching, and sound settings.

Customize your listening experience with built-in tone controls ( Bass / Treble / Subwoofer / EQ / Loudness ), and enjoy clear, room-filling sound with 4 x 40W maximum power output. 

Built for the elements and backed by Edge Audio’s commitment to quality, the MCR-1 is the smart, space-saving solution for anyone who wants great sound on the water or the trail—without sacrificing dashboard real estate.
