Marine Rated

Marine Receiver: At the factory, the Kenwood KMR-440U Marine receiver has a special water-resistant conformal coating placed on its main circuit board. This protects the circuitry from the harsh, corrosive marine environment. The receiver has special connections on the rear panel for the KCA-RC107MR and KCA-RC60MR wired marine remote controls (sold separately).

Water Resistant Cover (optional): Even though the conformal coating makes the receiver water-resistant, it is still recommended that it be used with a universal marine cover such as the Metra (120999005B, sold separately) or Scosche (142ACM1, sold separately)

24 Bit D/A Converter: The Kenwood Marine KMR-440U utilizes a 24-bit digital to analog converter for superior CD sound quality.

MOSFET Amplifier: The Kenwood Marine KMR-440U is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit. The power output specs for the KMR-440U are as follows:

• Full Bandwidth Power: 22 watts RMS x 4 channels (at 4 ohms, 20-20kHz, 1% THD)
• Maximum Output Power: 50 watts x 4 channels

Rotary Volume Control: The Marine CD receiver uses a 6-way rotary volume control that increases and decreases the volume of the stereo from 0 to 35. The rotary knob also controls other audio settings such as Bass, Treble and preset EQ settings. In addition, the rotary knob allows you to scroll through and select your music tracks when the Music Search function is activated.

Speaker Settings: The Speaker Setting function tailors the System Q Sound Control settings according to the type of speakers in your vehicle. You may select a Speaker Setting of "SP Off" (flat), "SP OEM" (for OEM factory speaker systems), "SP 6x9/6" (for systems with 6" and 6"x9" speakers), or "SP 5/4" (for systems with 4" and 5" speakers).

System Q Sound Control: Seven EQ curves are preset into memory, allowing you to recall the best preset EQ curve for different types of music. Each preset has its own level settings for bass (100Hz), midrange (1kHz), and treble (10kHz). You can choose from the following preset EQ curves - Rock, Pops, Easy, Top 40, Jazz, Natural, Game, and User.

System Q Sound Control: Six EQ curves are preset into memory, allowing you to recall the best preset EQ curve for different types of music.
