It's no accident that "eXcelon" sounds like "excellent." And that's what you'll be saying when you see the multicolor fluorescent display of the KDC-X811. With a MASK faceplate for security without a detachable face, and a built-in spectrum analyzer, you'll get the high-end features you've always wanted for less $$ than you'd expect.

This Kenwood eXcelon receiver is equipped with a high-power amp, but you might want to consider adding additional Kenwood eXcelon amplifiers and dB+ subwoofers to the three sets of preamp outputs. That way you can take full advantage of the Bass Management System, PowerSlide door, and System E's+ Advanced Crossover. You can add a CD changer to access up to 10 more CDs. And a wireless remote is packed in the box. Excellent? Yes, Kenwood eXcelon!

Add a Kenwood disc changer to your order and you'll save $$ with our package discount.

Changer Controls


MASK Security: The stealth mechanism on this unit reverses the faceplate so that only a blank panel is visible. When you turn the ignition on, the unit's power turns on and the faceplate reverses. You can also close the unit at any time by pressing the source button for over a second. When closed this way you can re-open the unit by sliding the "Manual Open Switch" to the left. The "Manual Open Switch" switch is located in the lower right hand corner of the panel, and you may select how many times (from 1 to 3) it must be slid to open the unit. You can enter a 4 digit security code which keeps you from turning on the unit without the code when battery power is removed.

Display/Faceplate: The unit has a multi-colored display. The FM frequencies, CD track, "News", "Text", "Dual", clock and dual info portion of the display (see below) are displayed in light blue. The loudness, CD-in and clock indicators illuminate in red. The Auto1/2 indicator illuminates in medium blue. There is an 8 band green colored spectrum analyzer on the left hand side of the display; this can be set to one of two spectrum displays or a character (icon) display. There is a bright blue source button and a red power LED in the upper right hand corner of the faceplate. This unit has dual button illumination. The button markings are illuminated in green and can be switched to red. This changes only the button illumination (except the source button which remains blue), it does not change the display illumination. The finish on this unit is a glossy, ebony black.

Plus/Minus Power Source: Generates higher supply voltages to audio circuits, enabling higher output levels with less noise and distortion. Additionally, the plus/minus power supply isolates the audio ground from the vehicle's chassis ground, eliminating ground loops and interference.

4.0-volt gold-plated front, rear and non-fading preamp outputs.

System E's+ Advanced Crossover System: Allows you to select a high pass filter on either the front or rear output, or both, (preamp outputs and speaker outputs) which can be set to 40, 60, 80, 100, 120, 150, 180 or 220Hz. You can set a low pass filter for the non-fading RCA of 50, 80, 120Hz or through and select the phase for the non-fading RCA of normal or reverse.

External Amp Control: Kenwood also calls this "B.M.S." (Bass Management System). When used with a compatible, Kenwood eXcelon amplifier, you can adjust the bass boost level of the amplifier through this head unit.You can select Flat, or boost the bass of the amplifier by +6 or +12dB.

Dual Info Display: In addition to the standard display line, which displays frequency/track/title info, there is a second display line in the lower center portion of the display window that can be set to display the clock, source, track time (only during disc play) or track number (only during disc play).

Faceplate Angle Adjustment: Using a switch mounted below the CD slot, you may set the unit to hold the display at one of two angles or flat against the front of the chassis.

Black Mask Display Setting: If you desire a less cluttered display appearance, you may turn off the lower part of the display. With the Black Mask function set to "on", only the main display line illuminates.

Display Dimming: This unit is equipped with an illumination wire that dims the display when headlights turned on. Dims to a preset level, you can select a dimmer level of 0-10, not affected by vehicle's dimmer control.

Auxiliary Input "Ready": When used with an optional adapter (KCA-S210A or CA-C1AX) or with the KDC-CX82 CD changer, this unit can accept input from an auxiliary source. This unit cannot accept input from an auxiliary source unless the appropriate adapter or CD changer is also purchased and connected. When the CA-C1AX adapter (item 113CAC1AX) is used, you cannot connect a CD changer to the head unit (the CA-C1AX plugs into the changer control DIN connection on the head unit).

Dual Zone Capability: This feature allows you to play an auxiliary source through the rear channels and the tuner or built-in CD player through the front channels.


  • To use the Dual zone feature you must purchase one of the following items: KCA-S210A, CA-C1AX, KDC-CPS82 or KDC-CX82.
  • When this feature is active, the bass, treble and loudness controls do not affect the rear channels.
  • When the Dual Zone system is on, the CD/MD changer controls are deactivated.

After a name has been assigned, you can press the DNPP button on the remote to display the name of each preset station for 5 seconds. When the name of the desired station appears, you can press the OK button on the remote to select the station. If a name has not been entered for a preset, the frequency will display. You hear the station that was tuned in prior to the DNPP button being pressed, you do not hear the stations as their names are displayed.

You can register up to 48 non-RBDS stations as program types. When you register a non-RBDS station as a certain program type it will be found when using PTY seek tune for stations in that particular category
  • Alarm: When in Tuner mode or when the Traffic Information function is turned on and an emergency transmission is made, this unit's tuner will automatically switch to the warning.
