Treat yourself to the premium sound and quality of a Kenwood Excelon CD receiver. The KDC-X491 CD receiver features a front-panel USB input for connecting — and controlling — your USB-capable portable music devices. Its powerful amplifer and premium digital-to-analog converter deliver crystal-clear sound for all of your tunes. Six preset tone curves give you quick sound changes, while a 3-band parametric equalizer offers fine tone adjustment.

The stereo plays MP3, WMA, and AAC music files from disc. For fans of portable music players, Kenwood's iPod® control adapter connects to the KDC-X491's CD changer port, keeping its other inputs free for your other gear. Connect your audio player to the USB input, and you can even access any purchased music files stored in the Microsoft PlaysForSure™ format. You'll also find a rear-mounted auxiliary input for connecting your non-USB music player.

If you have a larger system in mind, three sets of 4-volt preamp outputs make it easier to connect external amps and subwoofers. For optimum performance, you can manage your bass settings with the built-in subwoofer controls, and adjust the frequencies going to your various speakers with the high- and low-pass filters. You can also expand your listening options with a Kenwood HD Radio™ tuner or satellite radio.

The KDC-X491 comes with a 2-year warranty for extended peace of mind.

    Features

    Overview: The Kenwood KDC-X491 AM/FM CD receiver features a detachable face, rear auxiliary input, 3 sets of 4-volt preamp outputs, CD changer and Satellite radio controls, HD radio, Bluetooth and iPod ready functions, as well as a front 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.

    Detachable Face: The unit features a single front loading CD 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.

    AAC/MP3/WMA/WAV Playback: The KDC-X491 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-X491 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-X491 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-X491 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 4V Preamp Outputs: The KDC-X491 features front, rear and subwoofer 4V 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-X491 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-X491 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-X491 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.

    Receive Mode: If you choose to connect the optional HD tuner, the Receive Mode allows you to choose to receive analog or digital AM/FM broadcasts. You can choose from the following.

    • Auto: analog and digital broadcast will be received with the digital broadcast having priority
    • Digital: receives digital broadcasts only
    • Analog: receives analog broadcasts only

    Tel Mute: The KDC-X491 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-X491 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. It is powered by 2 "AA" batteries (supplied). The dimensions of the remote are: L = 5.362", W = 1.962", D = 1.115".

One end of the cable plugs directly into your iPod's dock connector while the other end of the cable uses two connectors that plug into the headunit. The USB type-A connector portion of the cable plugs into the receiver's front-panel USB port and handles the control and charging of your iPod, so you can navigate through your music files using the headunit's controls and view song info on it display. The 3.5mm miniplug connector portion of the cable plugs into the Auxiliary 3.5mm input on the receiver and transfers the music from your iPod to your Kenwood CD player. By using the Auxiliary input the music travels to the receiver as an analog signal, so you can even play the Digital-Rights-Protected files you've stored on your iPod. The controls of the KDC-X491 are seamless when used with the optional KCA-iP200 and include metadata browsing and playback of DRM contents, as well as the ability to choose any iPod playback mode to suit your listening application.

    Satellite Radio Ready: There are several options for connecting an optional XM or SIRIUS Satellite Radio receiver to this receiver:
    • XM Satellite Radio: To receive XM Satellite Radio, you can connect the optional CNP2000UC XM Mini Tuner and the CNP-KEN1 Kenwood adapter cable (package item number 700XMKEN1).
    • SIRIUS: To receive SIRIUS Satellite Radio, you can connect the optional SC-C1 SIRIUS Connect vehicle tuner (item number 607SCC1) and the Kenwood/SIRIUS adapter (item number 113KCASR50).
    • Dock: Select dock-and-play and portable SIRIUS radios can be controlled using the Kenwood/SIRIUS adapter (item number 113KCASR50) and the SC-VDOC1 dock (item number 607SVCDOC1).
    • Auxiliary Input: A portable satellite radio receiver, such as the Delphi SkyFi3 or SIRIUS Sportster, can be connected to the head unit via the auxiliary input (adapter may be required).

    Note: A subscription is also required to receive satellite radio programming from SIRIUS or XM.

    HD Radio Ready: With an optional Kenwood HD Radio tuner (item # 113HR100TR), you will be able to receive digital AM/FM broadcasts from local stations where available. This new technology will significantly improve audio quality and reception, as well as include information such as artist name and song titles or traffic news, viewable on the receiver's display.

    Bluetooth Ready: The unit is also Bluetooth compatible using the optional Kenwood KCA-BT100 Bluetooth adapter. Using this adapter you can make and answer phone calls from the Kenwood headunit. You can even download your Phonebook information from your compatible mobile phone into the headunit. You are able to register up to five compatible Bluetooth cell phones when using the KCA-BT100 adapter.

    USB Port: The Kenwood KDC-X491 features a front-panel 2.0 USB type-A port that is protected by a clear plastic, sliding window when not in use. The USB port enables connection to portable USB mass-storage players, USB thumb drives and audio control of MP3 player. The USB port is compatible with all USB mass storage class devices that support the FAT16 or FAT32 file system.  A single or multi-slot card reader can also be connected the USB port, allowing your music to be put neatly into different types of memory cards.

    Changer Controls: This unit is directly compatible with Kenwood changers manufactured in 1998 or later. If the changer has an O-N switch, the switch will need to be set to the "N" position.

When connected to a CD Text capable CD changer or an MD changer, this unit can display disc and track titles for discs encoded with disc and track title information. The text information can be scrolled manually or automatically.

    Additional/Optional Rear Auxiliary Input: The unit already features a rear panel auxiliary input, but if you need a second auxiliary input, another one can be added to the rear of the unit. When used with an optional adapter, this unit can accept a rear input from an auxiliary source. When the CA-C1AUX adapter (item 113CAC1AX) is used, you cannot connect a CD changer to the head unit because the adapter plugs into the DIN changer control connection on the head unit. When the KCA-S220A 2-changer switch (item 113KCAS220) is used, you can connect a CD changer and an auxiliary audio source at the same time. When an auxiliary audio source is connected, you can choose from one of six names for the source: Aux Ext, TV, DVD, Video, Game, or Portable.
