JL Audio MediaMaster 105-HR Premium Hidden Marine Source Unit – MM105-HR

MediaMaster 105-HR Premium Hidden Source Unit - MM105-HR

Engineered to operate behind the scenes as a hideaway receiver, the MediaMaster 105-HR includes all features of the MM105, minus the LCD 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.
