The MR-5 Marine stereo comes packed with 180 watts of power (4 x 45) and features a removable face. The stereo is wired remote ready allowing you access to your stereo from your swim platform, upper or lower helm, fishing deck, or wherever you need to have control of your stereo. Plus, you can hook up your MP3 player, Computer, Satellite Radio, or VHF radio through the handy auxiliary input to hear them through your audio system. Of course, the MR-5 features the patent pending Sea-top Technology and CRC Plasticoat 70 on both sides of the circuit board ensuring a longer lasting unit. The 1-bit DAC (digital to analog converter) eliminates zero-crossing ("glitches") to ensure higher fidelity than the conventional ladder-resister DAC's. A high-precision hologram pickup reads CD's with minimal errors while the digital servo optimizes the pickup movement to compensate for the distortion in the disc. Finally, the silicone damped, rubber encapsulated spring/suspension system protect the pickup from the shocks and vibrations of a bumpy boat ride. All components are made of water-resistant materials for greater durability. Combined with a Sea-gim3 watertight gimball housing, this package makes for a great value that will take the punishment the harsh marine environment dishes out.
