The Kenwood Excelon KDC-X591 CD receiver brings outstanding audio performance and near-endless playback variety to your car. It'll play discs loaded with MP3, WMA, and AAC files, and offers the convenience of both auxiliary and USB inputs. Add Kenwood's optional connecting cable, and you can use the USB and auxiliary inputs to control your iPod®.

Kenwood teams up a powerful amplifier with a premium digital-to-analog converter, so you'll enjoy warm, detailed sound with plenty of punch. Take control of the audio with six preset tone curves, then make fine adjustments with the 3-band parametric equalizer. Kenwood's Supreme audio feature adds extra zing to your compressed music files, while the fold-down face offers a large display for your song info.

If you have a larger system in mind, three sets of preamp outputs make it easier to connect your external amps and subs. You can manage your bass settings with the built-in subwoofer controls, and you can adjust the frequencies going to your various speakers with the high- and low-pass filters.

The KDC-X591 works with a Kenwood CD changer or satellite radio for more music options while you're on the road. Add Kenwood's Bluetooth® adapter for hands-free calling with your Bluetooth cell phone — the receiver mutes automatically for incoming calls, and you converse with both hands on the wheel and your eyes on the road.

This unit sounds great! My only complaint is the interface is too complicated, but I'm figuring it out! I also highly recommend the Ipod adapter Awesome

    Features

    Overview: The Kenwood KDC-X591 AM/FM CD receiver features a fold-down-detachable face, rear auxiliary input, 3 sets of 4-volt preamp outputs, CD changer and Satellite radio controls, Bluetooth and iPod ready functions, as well as a rear panel USB connector, plus AAC/MP3/WMA/WAV playback. The CD player comes with a soft face case and an IR wireless remote control. The unit's Mos-Fet amplifier is rated at 22 watts x 4 channel RMS and 50 watts x 4 channel peak.

    Fold-down Detachable Face: The unit features a fold-down face that detaches from the chassis to deter theft. There is a red indicator light that will flash on the unit after the face has been removed to warn potential thieves. You can turn this flashing LED on or off. The CD player comes supplied with a soft black fabric, draw string face case to protect the detachable face when you have it off the chassis. You must fold the face down before inserting or eject a disc.

    AAC/MP3/WMA/WAV Playback: The KDC-X591 can play MP3, WMA, WAV and AAC files with ID3 tag information recorded on CD-ROM, CD-R, and CD-RW discs in ISO9660 Level 1/Level 2, Joliet, Romeo and Long file name formats.

    24 Bit D/A Converter: The Kenwood KDC-X591 utilizes a 24-bit digital to analog converter for superior CD sound quality.

    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.

    AUX Input: The KDC-X591 is equipped with a rear panel 3.5mm minijack auxiliary input for connecting external portable audio devices such as an MP3 player or Tape walkman. The receiver allows you to turn the Auxiliary input On our Off so you don't have to scroll through that source if you are not using it. The 3.5mm female minijack connector is attached to a 7.5" pigtail.

    Auxiliary Display: The KDC-X591 allows you to select the source type displayed when using the auxiliary input. You can choose from AUX, DVD, Portable, Game, Video or TV.

    Dual Zone: The Dual Zone mode allows you to output the Main source and the Auxiliary input separately for the front and rear channels. You can select whether the auxiliary input will play in the front or the rear.

    3-Sets of Preamp Outputs: The KDC-X591 features front, rear and subwoofer preamp outputs. The Subwoofer preamp output can be turned On or Off and adjusted independently. The front and rear speaker preamp outputs are balance and fade adjustable. The subwoofer preamp output is non-fading. The front and rear preamp outputs are fixed to the chassis, while the subwoofer output is  on 7.5" pigtail lead.

    Front and Rear High-Pass Filter: The KDC-X591 features an independent High-Pass Crossover for the front and rear channels. You can adjust the high-pass crossover from through, 40, 60, 80, 100, 120, 150, or 180, 220Hz. 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.

    Low-Pass Filter: The receiver features a built-in Low Pass Filter control for the preamp-output when the Subwoofer Output is "on". You can select from 50, 60, 80, 100,120Hz or Through. The "Through" setting allows your external amplifier's crossover network to do all the filtering for your subwoofer.

    Subwoofer Level: Once you have switched the Subwoofer Output to "on" you can independently control the subwoofer preamp output level from the CD receiver. You select levels between -15 to +15.

    Subwoofer Phase: You can adjust the phase of the subwoofer output between 180-degrees (Reverse) or 0-degrees (Normal).

    Rotary Volume Control: The CD receiver uses a 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.

    Attenuator: The CD receiver features an Attenuator button that turns the volume down very quickly with one touch of one button.

    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).

    Note: The Speaker Setting affects the bass, midrange, and treble values of the System Q presets. The speaker setting should be selected first.

    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. Each preset has its own level settings for bass (100Hz), midrange (1kHz), and treble (10kHz). The 6 preset curves with their respective bass, mid, and treble levels are as follows:

    • Rock: Bass +6, Mid +1, Treble +2
    • Pops: Bass +3, Mid +2, Treble +6
    • Easy: Bass +6, Mid 0, Treble -2
    • Top 40: Bass +3, Mid +1, Treble +8
    • Jazz: Bass +5, Mid +2, Treble +2
    • Natural (Flat): Bass 0, Mid 0, Treble 0

    Note: The above values reflect the System Q settings when the Speaker Setting function is turned off. When the Speaker Settings are selected, the System Q level settings are different.

    Bass/Treble/Mid Control: The KDC-X591 features independent Bass, Treble and Midrange control. You can adjust each one from -8 to +8db.

    Detail Audio Control: The Detail Audio Control allows you to adjust the following settings for the Bass, Treble and Mid levels.

    • Bass Level:
      • Frequency: 40/50/60/70/80/100/120/150 Hz
      • Q-Factor: 1.00/1.25/1.50/2.00
      • Bass Extend: On/Off (when this feature is set to "On", the low frequency response is extended by 20%)
    • Mid Level:
      • Frequency: 0.5/1.0/1.5/2.0 kHz
      • Q-Factor: 1.0/2.0
    • Treble Level:
      • Frequency: 1.0/12.5/15.0/17.5 kHz

    Loudness: The Loudness feature compensates for low and high tones during low volume. You can turn this feature either on or off. Only the low tone is compensated for when the tuner is selected as a source.

    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.

    Source Tone Memory: This feature allows you to store System Q bass, middle and treble tone settings for each source (CD, FM, AM and Aux).

    Text/Title Scroll: The KDC-X591 will display CD text, Audio file text and Satellite and HD radio text. You can turn the scrolling feature "on" to scroll longer titles across the screen.

    Last Position Memory: If the unit is shut off or switched to the tuner mode while a CD is playing, the next time CD is selected as the source, playback will resume from the point where it left off.

    CD Force: When there is a problem with playing a CD with a special format, this setting plays the CD by force. Some CDs still may not play in the CD Force mode.

    CR-2 Advanced Tuner: This unit uses Kenwood's CR-2 Advanced tuner for clear radio reception. You can choose one of three tuning modes: Auto 1 (seek tuning), Auto 2 (cycles through and tunes the selected band's preset stations only with each button press), or Manual.

    Auto Memory Tuning: Not only does the CD receiver's tuner allow you manually enter your desired presets you can choose to have the unit automatically put stations with good reception in the memory banks automatically; this is a handy feature when traveling. The tuner features 3 FM banks (1, 2, 3) and 1 AM bank. You can store 6 presets for each AM/FM bank giving you a total of 18 FM presets and 6 AM presets.

    Clean Reception System Circuit (CRSC): This circuit controls multi-path distortion by reducing stereo separation. As stereo separation is reduced, multi-path has less effect on the radio signal, improving reception in areas with tall buildings and mountains. The CRSC circuit can be turned on or off.

    Tel Mute: The KDC-X591 features a cell-phone mute wire (brown) 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.

    Beep Tone: The CD player features a touch sensor tone that beeps when you have selected a function of the unit. You can turn the beep tone ON or Off.

    Security Code: You can enter a 4-digit security code which must be used when the unit is removed from the vehicle, or the constant power source is disconnected from the unit. When constant power is restored to the unit, the security code must be entered before the unit becomes operational.

    FL Display: The unit features a large 14-segment Fluorescent display that uses a black background and blue characters that are easy to read.

    Display Illumination/Clock Display: When the unit is in Standby mode, the face/button illumination is "keyed." In addition, while the unit is in Standby mode, you can turn the clock display on or off. When the Clock Display is turned on and the unit is in Standby mode, the Clock Display is also "keyed." Pressing and holding the source button turns the unit off completely.

    Display Illumination Control: This function turns off the display when have not performed an operation for 5 seconds. This is effective for when you are driving at night.

    Dimmer: The dimmer function will dim this unit's display automatically when the vehicle light switch is turned On when you connect orange/white Illumination wire of this player.

    Remote Control: The KDC-X591 comes with the RC-547 IR wireless remote control with a full numeric keypad. The remote will control Audio, CD, Tuner, Satellite, HD radio and Dual Zone functions.
