Marine Rated
Marine Receiver: At the factory, the Kenwood KMR-550U 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.
Water Resistant Covers (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).
Display Features
Detachable Face:
The Kenwood KMR-550U features a single front loading CD face that detaches from the chassis
to deter theft. The head unit includes a cloth pouch for storing the face-plate when
detached. A face-fixing screw is supplied for making the face non-detachable, if
desired. An optional soft face case (142DFC1X,
sold separately) can also be purchased for this unit.
Multi-Line Text Display: The 3-line full dot LCD makes it
easy to navigate through your disc's music, radio presets, iPod music library,
or USB content. The KMR-550U offers five different display types:

12-hour clock and date (M/D/Y) display. You can even set times for two different
cities (dual clock display).

vehicle's ignition switch is set to ACC or On.
Note: You cannot connect a USB device via a USB hub or
Multi-Card Reader to this unit.
Music Editor Compatible: The Kenwood KMR-550U supports the

unit has 3 auxiliary input modes.
- On1: Outputs the sound of the external unit connected
to the Aux terminal when switched to the Aux source.
- On2: Activates the attenuator function when turning on

Audio Section
24 Bit D/A Converter: The Kenwood KMR-550U utilizes a
24-bit digital to analog converter for superior CD sound quality.
MOSFET Amplifier: The Kenwood KMR-550U 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-550U 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
7-Way Rotary Volume Control: The CD receiver uses a 7-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 Balance, Fader, Bass,
Mid, 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.
Volume Offset: The level of each source may be independently
adjusted to prevent radical leaps in output volume when switching from one
source to another. The available settings range from -8 to 0 (-8 to +8 for Aux
source).
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/off), '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).
Preset EQ: Eight 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 (12.5kHz). You can choose from the following preset EQ curves - Rock,
Pops, Easy, Top 40, Jazz, Natural, Game, and User.
Bass Boost: In addition, The Kenwood marine CD receiver features a
Bass Boost control that can be set to the following levels (BB1, BB2 or Off).
Loudness: This function enhances low and high frequencies to
make the sound clearer lower volumes. There are 3 levels (LV1, LV2, or Off).
Source Tone Memory: This feature allows you to store System
Q bass, middle and treble tone settings for each source (CD, AM/FM, Aux, USB,
iPod, and Pandora).
Supreme Setting: When MP3 or WMA files encoded at a low bit
rate (less than 96 kbps, 44.1k, 48kHz) are played, the Supreme Setting function
restores their high frequencies so the sound quality is closer to files encoded
at a high bit rate. The processing is optimized for the compression format and
the bit rate used. When the Supreme Setting is Off, the unit plays the original
sound stored in the audio file.
6ch/2.5V Preamp Outputs: The KMR-550U features front, rear
and subwoofer 2.5-volt preamp outputs. The front and rear speaker preamp outputs
are balance and fade adjustable. The subwoofer preamp output is non-fading. The
front, rear, and subwoofer preamp outputs are fixed to the rear chassis of the
head unit.
Front & Rear High-Pass Filter: The KMR-550U features an
independent High-Pass Crossover for the front & rear channels when your front &
rear speakers are connected by the unit's speaker-outputs or preamp-outputs. You
can adjust the high-pass crossover from "Through", 100, 120, or 150 Hz. The
"Through" selection is a full-range setting. This feature is very helpful when
you have smaller-type speakers in the front and larger-type speakers installed
in the rear of the vehicle.
Subwoofer Controls: The Kenwood KMR-550U offers the following subwoofer controls, when you have the
unit's subwoofer preamp output activated.
- Low Pass Filter: The receiver
features a built-in Low Pass Filter control for the preamp-output, when the
output is set to Subwoofer. You can select from 85 Hz, 120 Hz, 160 Hz, or off.
- Subwoofer Phase: You can adjust the phase of the
subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).
- Subwoofer Level: Once the Subwoofer preamp output is
activated, you can independently control the
subwoofer preamp output level (-15 to +15) from the CD receiver.
Tel Mute: The KMR-550U features
a cell-phone mute wire (tan) in its harness that when hooked up to your car's
phone system mute wire will automatically mute the receiver's audio signal when
a call comes in.

included wiring harness that lets you keep your vehicle's factory radio steering
wheel remote controls when used with an optional
steering wheel audio control adapter (sold separately). Please consult
Crutchfield's
Outfit My Car to see if your vehicle is compatible.
