{"product_id":"qbp102633","title":"JL Audio MediaMaster 55 Marine Source Unit, NMEA 2000 Certified, 10-16V, IP67, 3-Zone Audio, Bluetooth, 2.8 in Color LCD","description":"\u003ch6\u003eOverview\u003c\/h6\u003e\u003cp\u003eThe JL Audio 010-03365-00 is a weather-resistant marine source unit with a 2.8-inch TFT full-color display (320 x 240) and three audio zones for independent control around the boat. The front-panel design is IP67-rated for spray, washdowns, and open-cockpit use, and it runs on 10 to 16 V DC electrical systems.\u003c\/p\u003e\u003cp\u003eFor speaker power, it includes a built-in amplifier rated at 25W x 4 at 4 ohms for Zones 1 and 2, with a 2 ohm minimum per channel when your system requires it. Each zone also supports RCA preamp outputs with a stereo pair plus a dedicated mono subwoofer output, letting you mix powered zones and external amps without having to compromise the layout.\u003c\/p\u003e\u003cp\u003eSources cover the usual onboard mix: Bluetooth (with SBC and Qualcomm aptX audio), USB 2.0, and an analog AUX input, plus AM\/FM tuning with RDS and 18 presets. NMEA 2000 networking is built in via a Micro-C connection (LEN 1) for integration with compatible displays and network remotes.\u003c\/p\u003e\u003ch6\u003eKey features\u003c\/h6\u003e\u003cul\u003e\n\u003cli\u003eIP67-rated face and controls for marine exposure and routine washdowns\u003c\/li\u003e\n\u003cli\u003e2.8-inch TFT color display with 320 x 240 resolution for at-helm visibility\u003c\/li\u003e\n\u003cli\u003eThree-zone audio architecture with per-zone stereo preamp outputs and a mono subwoofer output\u003c\/li\u003e\n\u003cli\u003eBuilt-in amplification for Zones 1 and 2: 25W x 4 at 4 ohms, with 2 ohm minimum per channel\u003c\/li\u003e\n\u003cli\u003eSystem-friendly power requirements: 10 to 16 V DC input, 15 A max draw, 15 A fuse value\u003c\/li\u003e\n\u003cli\u003eBluetooth audio plus USB 2.0 playback with up to 1 A device charging\u003c\/li\u003e\n\u003cli\u003eNMEA 2000 connectivity on a Micro-C port (LEN 1) for network integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch6\u003eInstallation and fit\u003c\/h6\u003e\u003cp\u003eThis unit is meant for a flush helm or console install. The mounting hole size is 3.74 in wide x 3.15 in high (95 mm x 80 mm), and the overall chassis measures 4.65 in x 3.74 in x 3.66 in (118 mm x 95 mm x 93 mm). Before cutting, confirm you have room behind the panel for the chassis depth and for cable bend radius on power, speaker leads, RCA outputs, antenna, and network connections.\u003c\/p\u003e\u003ch6\u003eElectrical and system integration\u003c\/h6\u003e\u003cp\u003ePlan it like a 12 V-class device: operating voltage is 14.4 V DC nominal (10 to 16 V range) with up to 15 A current draw, so it should be fed from a properly protected circuit using the specified 15 A fuse. If you are pairing it with external amplifiers, the 4V RMS preamp output setting (Relative or Absolute modes) can help keep gain structure clean when runs are long and the environment is noisy.\u003c\/p\u003e\u003cp\u003eFor networked boats, the NMEA 2000 Micro-C connection lets the source unit participate on the backbone. Keep backbone power and termination correct, and avoid spurs that are longer than your network design allows so control stays responsive underway.\u003c\/p\u003e\u003ch6\u003eAudio setup on board\u003c\/h6\u003e\u003cp\u003eThe three-zone layout is handy when the cockpit, cabin, and bow need different volume levels or different content. Each zone includes tone and balance controls plus selectable high-pass filtering (Off, 80 Hz, 100 Hz, 120 Hz) and low-pass filtering for subwoofer outputs (Off, 60 Hz, 80 Hz, 100 Hz), which helps you keep deck speakers clean while letting subs do the low end.\u003c\/p\u003e\u003cp\u003eThis is a good match for boats that have multiple listening areas and want one head unit that can manage them without extra zone processors. It also fits well in refits where you are upgrading from a single-zone stereo but want to keep existing amps and speakers while adding better control and tuning.\u003c\/p\u003e","brand":"JL Audio","offers":[{"title":"Default Title","offer_id":52256224346293,"sku":"QBP102633","price":463.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0977\/8171\/1029\/files\/1284811_qbp102633.webp?v=1771286680","url":"https:\/\/www.qualityboatparts.com\/products\/qbp102633","provider":"Quality Boat Parts","version":"1.0","type":"link"}
