Hidden behind the water-resistant fold-down face, the shockproof storage pocket protects and charges your Apple® or Android smartphone while you're enjoying tunes from your digital media collection. The generous tray size accommodates a variety of devices, including the Samsung Galaxy S8 and iPhone® X.

NMEA 2K-compatible

The Fusion MS-UD755 can handle all your entertainment and communications needs when you're out on the water. In addition to working with a variety of wired and wireless devices, you can connect this highly-advanced receiver to your NMEA 2000 network. This lets you communicate with any Fusion-Link™ certified Multi-Function Display or Fusion NMEA 2000-certified wired remotes (connectors sold separately). An internal software switch allows you to choose between NMEA or "traditional" receiver functionality.

Plenty of cool connections

Built-in Bluetooth® connectivity lets you stream music wirelessly using your smartphone, while you view track information on the color display. The MS-UD755 supports iPod® or iPhone® audio and you can even enjoy Pandora control with “Thumbs Up/Thumbs Down” voting capability. The large rotary encoder controls most functions, while the color LCD screen lets you see what's playing. You'll also see album art and other graphics on your phone when you use the Fusion-Link app.

If you love satellite radio, you can connect a SiriusXM tuner (subscription also required) to enjoy music, sports, entertainment, news, and essential weather-related content when you're many miles offshore. And if you store your entertainment library on a USB thumb drive or portable device, the MS-UD755 includes the inputs you need to get connected and get crankin'.

Built-in ANT connectivity even allows you to control the MS-UD755 with your Garmin smart watch.

Best of all, with Fusion's innovative Zone Control, you can adjust the volume in up to four distinct zones – a great feature for larger vessels or tour boats.

Stylish and seaworthy

Fusion designed the MS-UD755 to be tough enough for marine duty, but also for ease of use. The fully-sealed aluminum chassis serves as a solid foundation, while the face and switchgear are IPX5 water-resistant. Designed specifically for the rigors of the marine environment, this receiver is backed by the Fusion True Marine™ 3-year warranty.

Bluetooth note: Use of this receiver's Bluetooth features will depend upon your phone's Bluetooth capabilities. Learn more in our article explaining Bluetooth profiles.

    Audio Section

    Class D Amplifier: The Fusion MS-UD755 is equipped with a 26 watt RMS (70W Peak) x 4 channel stereo Class D amplifier for driving two pair of full-range marine speakers. Amplifier components are optimally configured for the side-fin aluminum heat sink, producing greater thermal efficiency

    3V/3Ch Pre-Outs Per Zone (1-2-3-4): The Fusion MS-UD755 features 3V/3ch pre-outs for each Zone (1-2-3-4). Each set of 3ch pre-outs include stereo left/right channels and a mono-sub channel. You can set the head unit's low-pass sub pre-out filter to 55, 85, 120, or 160Hz for the mono-sub channel. You can also adjust the output level of the unit's sub pre-outs independently from the receiver's overall volume control.

    Audio Controls: You can adjust the marine receiver's bass, mid, & treble from -12 to +12. You can also balance the sound from left to right. In addition, you can set the head unit's maximum volume limit for all three Zones.

    Multi-Zone Technology: The MS-UD755 marine stereo features multi-zone technology which enables four audio Zones with independent volume control from the system's built-in amplifier and pre-outs. Each audio Zone will play the same source, but offers independent volume control of each Zone. You can set the balance, volume limit, subwoofer level, and name for each of the zones. When using the MS-UD755's built-in amplifier, up to two pairs of speakers can be connected per zone in parallel to increase the amplifier output. When using the unit's pre-outs, you will need an additional amplifier in that zone.

    Dual Aux Inputs: Fusion's MS-UD755 marine stereo is fitted with two rear-panel stereo RCA auxiliary inputs for connecting external audio devices, other than an iPod/iPhone or Android device. The Aux inputs allow for a wide range of input levels thanks to its adjustable input gain (-9 to +9 dB).

    Mounting Options

    Bulkhead Mount: The MS-UD755 requires a rectangular cutout in the bulkhead for inserting the chassis. The marine receiver has a shallow mounting depth, perfect for space conscious installation on small boats and personal watercraft, where this is especially crucial. Four screws (supplied) fasten the faceplate against the mounting surface, and hold the waterproof gasket against the bulkhead. A paper template is supplied to assist you with the cutout and drilling the screw holes.

    • Cutout Width = 7.125"
    • Cutout Height =  2.125"
    • Cutout Depth =  7.875"
    • Nose Width = 8.5625"
    • Nose Height =  3.125"
    • Nose Depth = 1.375"
    Note: The screw holes are spaced 7.6875" (w) x " 2.5625 (h) apart.

    Hinged Door: Because of its folding-face plate to access the integrated UNI-Dock , there needs to be at least 0.625" of space left below the unit's front-panel and 3.5" of space in front of the front-panel in order to allow the hinged door to open.

    Mounting Angle: You can install the unit within 45° of horizontal.
