The exciting high-definition, animated display will look even better with backgrounds and movies that appeal to your tastes!

In addition to playing your MP3 and WMA discs, this versatile CD receiver also has a convenient auxiliary input to add the sound from a video game or portable music player to your system. Use the 7-band equalizer to tame the powerful MOSFET60 (26 watts RMS x 4) internal amp. Your music will be turbocharged for serious sound!

Three sets of 5-volt preamp outputs deliver a pristine signal to your external amplifiers so your music will sound awesome. The strong voltage delivers a high-quality, clean signal to your amps for noise-free amplification. Use the built-in crossovers to direct the mids and highs to your speakers and the lows to your subwoofer. Your music will sound more accurate and have less distortion.

Don't have a subwoofer, but still want some bass focus? If you have large rear speakers, then Panasonic's "Super Bass Control Subwoofer" feature can help. It's a low-pass filter that blocks the mids and highs from your rear speakers, utilizing them as woofers to help emphasize the bass.

Panasonic protects the MXE line of receivers with a 2-year warranty.

Product Research

CD Changer Controls


HD 3DDM Display: The CQ-C8400U is equipped with a High Definition 3-D Dot Matrix Display. The large front panel display (approximately 3-1/2" x 1") features 20,480 dots (pixels), providing music-synched 3D action graphics with crisp detail. Full-dot LCD technology enables 4-level gradation for smooth, attractive images. The display's brightness can be set to one of three settings. The contrast setting can be adjusted from 0 to 5.

Display Settings: In the display menu, there are 6 graphic background patterns to choose from, including a 25-band spectrum analyzer display, and 10 still image background displays. In addition, you can select to randomly display all the graphic patterns or all the still images. You can then select to display the chosen graphic pattern (with or without source info), the chosen still image (with or without source info), a plain background (with or without a large clock display), or completely turn off all displays.

Customize Display Function: The unit's display can be customized, allowing you to load your own moving or still images to replace the original graphic patterns, still images, and opening and closing images. Sample images and writing software can be downloaded from a special Panasonic web site. Note: Images should be written on a CD-R or CD-RW disc for transferring to the receiver. No more than 10 moving images, 15 still images, 5 opening images, and 5 closing images should be written to the disc. Maximum image size is 751KB.

Motorized Tilting Face: This unit features a motorized slide-down faceplate. The face automatically tilts to allow you to insert or eject a CD. The face angle can be adjusted to one of three settings (15°, 25° or 35°), or remain upright, whichever angle gives you the best visibility. When the face is removed, a red LED blinks on the front panel of the radio. The security indicator can be deactivated. Note: The bottom of the faceplate protrudes approximately 1-1/2" when a CD is being loaded or ejected.

Day and Night Faceplate: This unit also features the Day and Night faceplate. During the day, the face is dark gray with a silvery mirror-like finish on the ends. At night, or whenever it's dark in the vehicle, the outside edges of the faceplate and a "halo" around the volume knob illuminate in blue.

MP3/WMA Playback: This unit can play MP3 and WMA files recorded on CD-ROM, CD-R, and CD-RW discs in ISO9660 Level 1/Level 2, Apple Extension to ISO9660, Joliet, and Romeo formats. Each disc should have a maximum of 8 trees, 255 folders, and 999 files. Each folder can have a maximum of 255 files.

SQ7: The CQ-C8400U features a SQ7 "Sound Quality" 7-band equalizer with 6 EQ presets. The presets include Rock, Pop, Vocal, Jazz, Club and Flat. You can further adjust any of the 7 EQ bands from -12dB to +12dB: 60Hz, 160Hz, 400Hz, 1kHz, 3kHz, 6kHz and 16kHz.

Subwoofer Output: In addition to front and rear preamp outputs, the CQ-C8400U has a non-fading, two-channel subwoofer output. You can adjust the volume of the subwoofer output from -6dB to +6dB in 2dB increments plus "subwoofer mute". The subwoofer output has a low-pass filter with a selectable 80Hz, 120Hz or 160Hz cutoff frequency.

Super Bass Control Subwoofer (SBC-SW): You can drive small subwoofers with the rear speaker outputs with the SBC-SW. When the SBC-SW is activated, the subwoofer level and low pass filter settings are applied to the rear speaker outputs.

High Pass Filter: This unit has a built-in high pass filter for the front and rear speaker and preamp outputs with a selectable crossover frequency (90Hz, 135Hz, 180Hz, 225Hz or Off). Note: When the SBC-SW is activated, the high pass filter affects the front outputs only.

Mute/Attenuate: This unit allows you to choose between mute (volume at 0) or attenuate (volume decreased by 10 steps) when you want to decrease the volume instantly.

Auxiliary Input: A set of female RCA jacks is provided to allow the connection of a portable audio source. Just connect your portable cassette, MD or MP3 player to this unit, and you can listen to the audio from the portable player through the speakers in your mobile audio system. The jacks are on a 6" long pigtail attached to the back of the unit.

Alphatuner V: The CQ-C8400U's Alphatuner V tuner is designed to help suppress multi-path distortion and reduce the problem of radio signal reflections in metropolitan areas. It also features increased sensitivity for weak signal areas.

Direct Memory: One favorite radio station can be stored in Direct Memory and recalled at any time (even with the power off) with the push of the D-M button. In addition, you can store up to 18 FM and 6 AM stations in preset memory.

Remote Control: The CQ-C8400U is equipped with a wireless remote control (YEFX9992663). In addition to normal disc/tuner/audio controls, some functions are available exclusively by remote control only. The dimensions of the remote are: W=1.583", H=0.268", L=3.412".

Dual CD Changer Control: Using the optional CA-CD55 (item # 133CACD55) Dual CD changer adapter, you can control two compatible CD changers with this unit.

  • Disc Up/Down
  • Direct Disc Selection (remote only)
  • Track Up/Down

Installation Issue: The CQ-C8400U features a DC/DC converter for additional power. The converter is attached to the back of the receiver via a 5-wire, 15" harness. The harness is hardwired at the receiver and can be detached at the converter. The converter is 3.635" long x 1.538" high x 2.317" wide including mounting flanges. Space for mounting the converter in the dash must be considered when installing this receiver.

Clock/Illumination Displays: Pressing and holding the Source button turns the unit off completely. After the unit has been turned off, you can use the DSP (display) button to switch the clock display and face/button illumination on and off. If you leave the clock display and face/button illumination on, they are "keyed". If you turn the clock display and face/button illumination off, they only turn on when the unit is turned on ("unit on" operation).
