JL Audio 99979 Premium Hidden Marine Source Unit

Engineered to operate behind the scenes as a hideaway receiver, the MediaMaster® 105-HR includes all features of the MM105, minus the LCD display and physical controls. This full-featured, concealed source unit delivers top-flight sound performance and advanced audio features specifically designed for marine applications. Outfitted with NMEA-2000® connectivity, the MM105-HR can be controlled by your Garmin, Lowrance, Raymarine or Simrad Multi-Function Display (MFD) or MMR-40 NMEA 2000® Network Controller (sold separately).

Because sound quality is our top priority, the MM105-HR is not equipped with an internal amplifier designed to drive loudspeakers directly. Instead, it offers twelve channels of audiophile-quality, preamp level outputs to deliver crystal-clear signals to high-quality marine amplifiers. These are deployed via four configurable, nameable audio zones, each with its own set of independent control options, making the MM105-HR adaptable to a wide range of system types. On-the-fly, level controls make adjusting each or all audio zones a breeze, while a useful volume limit feature ensures that nobody gets blasted inadvertently. All zones feature our Zero-Clipping audio circuit design, with self-limiting tone controls to keep the audio clean at high listening levels, reducing the likelihood of speaker damage.

    • NMEA 2000® MFD Control - Use your compatible Multi-Function Display from Garmin, Simrad, Lowrance or Raymarine (refer to MFD manufacturer for compatibility info)

  • Marine Materials / Testing
    Building serious marine products requires a real commitment to environmental testing and materials specification. To this end, JL Audio has invested in Ultraviolet testing chambers (to simulate years of sun exposure) and Salt Fog chambers (to simulate years of exposure to salt-water environments). This testing is critical to building products that will not only sound great in your boat, but will also sound great for many, many years.
    • Materials Used:
      • Injection-molded mica-filled polypropylene cone bodies with synthetic rubber surrounds, specifically formulated with UV inhibitors for marine duty.
      • Marine-grade, synthetic fiber spiders with progressive roll designs to withstand high humidity.
      • Specifically engineered polymer baskets are corrosion and UV-resistant and encapsulate the woofer's motor system to prevent corrosion.
      • Gold-plated, marine-grade brass connection terminals
      • Marine-grade stainless steel mounting hardware is included.
