About the Sony CDX-M800

The CDX-M800 CD receiver upgrades Sony's Active Black Panel to an exciting full-motion fluorescent display with high-resolution graphics and screensavers! Open the faceplate, and the inner panel features a smaller LED display and soft-touch controls. Close the faceplate, and use the wireless remote to control the receiver when viewing the extra-large display. When you power down, the Active Black Panel does double-duty by disguising the receiver as a featureless panel in your dash.

If your car has speakers low in the door, you'll appreciate the Dynamic Soundstage Organizer. It raises the stereo image off the floor, making your music sound more robust and exciting. No matter where your speakers are, Sony's 4-way high power will give them the juice they need to make your tunes come to life! Fine tune the sound with the seven preset curves and 7-band equalizer of EQ7.

Add an XM tuner and you're primed for the crystal-clear, diverse programming of XM Satellite Radio (antenna and subscription required). If you want even more entertainment, the CDX-M800 will also control a Sony 6- or 10-disc CD changer. Front, rear, and subwoofer preamp outputs simplify adding outboard amps to your system.

Product Research

Changer Controls


Active Black Panel: The CDX-M800 features the Active Black Panel with fluorescent full-motion display. Since there are only two small buttons on the front, the display area is very large. When the unit is on, the bright fluorescent display offers numerous modes of full-motion graphics. When the unit is turned off, the entire face goes dark making it difficult to be spotted by a potential thief.

Fluorescent Full-Motion Display: The unit's two-color fluorescent display technology gives you better resolution than conventional LCDs, and lets data transition faster for smooth, clean, solid movement of graphics. The resolution of the display is 139(H) x 39(V). You can cycle through all of the motion displays with the face closed using the remote or a small button on the face. The motion displays include: surfing, snowboarding, Xplod, and four graphic motion displays. There are also 2 static displays (a pair of gauges and a car) and an information display (CD track/Tuner frequency).

Motorized Fold-Down Faceplate: This unit is equipped with a motorized fold-down faceplate. When you press the Open button, the faceplate flips down, revealing the CD slot, a smaller display and a full control panel. You can fully control the receiver with the face open or closed (using the supplied remote). The panel protrudes approximately 1.75" when the face is open, and just under 1" when the face is closed.

Dimmer Control: In the menu, you can select the Display Dimmer function to be "Off" (display is always bright when the unit is on), "Auto" (display dims only when vehicle's lights are on), or "On" (display is always dimmed). Note: In the "Auto" mode, the unit's illumination (orange/white) wire will need to be connected to the vehicle's headlamp circuit in order to operate properly.

Dynamic Soundstage Organizer (DSO): Sony's Dynamic Soundstage Organizer uses proprietary circuitry to induce subtle phase shifts, simulating a sound source that is placed higher than the actual speakers in the vehicle. For example, when the DSO function is used in a vehicle equipped with speakers mounted low in the front doors, it creates virtual speakers in the dash to raise the soundstage. This unit offers three levels of DSO, each with a larger and higher soundstage. You can store the DSO setting for each source.

Subwoofer Output With Low-Pass Filter: The CDX-M800 has a mono subwoofer preamp output with level control and a built-in low-pass filter. You can select a 78Hz or 125Hz crossover frequency, or turn off the filter. Note: The subwoofer output has two female RCA jacks. 

High-Pass Filter: This unit has a built-in high-pass filter for the front and rear preamp and speaker outputs. You can select a 78Hz or 125Hz crossover frequency or turn off the filter.

EQ7: You may select one of the following EQ presets: Xplod, Vocal, Club, Jazz, New Age, Rock, or Custom. For each preset, you can adjust the following frequencies: 62Hz, 157Hz, 396Hz, 1kHz, 2.5kHz, 6.3kHz, and 16kHz. The level of each frequency can be adjusted from +10dB to -10dB in 1dB increments.

Source Tone Memory: You can store a different EQ7 level setting for each source.

Aux Lite Auxiliary Input: The CDX-M800 has an auxiliary input on the rear panel, allowing you to connect a separate audio source, such as a portable minidisc or MP3 player, or the audio output from a mobile/portable DVD player. In the past, Sony receivers required a separate adapter, however, this unit's "Aux Lite" input allows you to directly connect the auxiliary unit to the receiver's stereo RCA input jacks. Note: If a CD/MD changer is connected to this receiver, you will not be able to connect an auxiliary source without an adapter (158XA300).

XM Satellite Radio Controls: This unit can control an optional Sony XM tuner (item 158XTXM1). The optional tuner, along with an antenna and subscription, will allow you to receive XM Satellite Radio. XM Satellite Radio programming features up to 100 channels of digital-quality music, news, talk, sports, entertainment, and children's programming.

SSIR-EXA Adaptive Reception: The SSIR-EXA tuner is equipped with "Adaptive Reception". The Adaptive Reception feature has two modes ("IF Auto" and "Wide") for optimizing FM reception. The "Wide" mode decreases the tuner's selectivity but results in better frequency response. The "IF Auto" mode automatically adjusts the tuner for a good balance between frequency response and minimum station-to-station interference. The Adaptive Reception feature cannot be turned off. You can also manually switch to local or monaural FM tuning to help improve signal reception.

Best Tuning Memory (BTM): This feature selects stations with the strongest signals within the selected band and stores them in order of their frequency.

Station Memo: You can assign a name of up to 8 characters to each radio station and store it in memory. The name of the station currently tuned will appear in the display. You can also locate a preset station by name by pressing the List button. When the desired station is located, you can press Enter to tune in the station. If a preset station has not been assigned a name, its frequency will be displayed.

Active Servo Control: To reduce the chances of CD skipping, the CDX-M800 uses Active Servo Control (ASC). Sony's unique ASC provides real-time monitoring and adjustment of the laser servos which control the laser's tracking and focus and the rotation speed of the disc. As the disc is read, the laser's reflection is analyzed and the data is evaluated for errors. If scratches or dirt reduce the reflection, the focus servo's gain is increased so the laser can read through the imperfections. If the tracking signal begins to show a large error percentage, the system increases the tracking servo's gain to maintain stable operation.

CD Text/Disc Memo: If the CD played in this unit has CD Text, the information will appear in the display. Typical CD Text information includes artist name, disc title, and track name. If the unit's Auto Scroll function is set to "on", names exceeding 8 characters will be scrolled across the display. In addition, if you are using a CD/MD changer with CD Text/Custom File, you can enter a custom name of up to 8 characters for the disc (Disc Memo), which will override the CD Text information.

60-Degree Installation: For flexibility of installation, this unit can be mounted between 0 (horizontal) and 60 degrees.

Menu Functions: The Set Up and Display functions can be set or changed through the unit's menu system. The menu choices cycle through on the large ABP display or the smaller sub-display when the face is open.

Remote Control: The CDX-M800 comes with a wireless, card-sized remote control (RM-X110). The dimensions of the remote are: W=2.052", H=0.478", L=4.931". The receiver is also compatible with the optional RM-X6S Wireless Rotary Commander remote (item 158RMX6S). These remotes allow full functionality of the receiver, even with the face closed.

Changer Controls

CD/MD Changer Control: In addition to playing a CD in the unit, the CDX-M800 can control an external CD/MiniDisc changer, including a CD changer capable of playing CD-Rs and CD-RWs encoded with MP3 files. If the changer has CD Text capability, the CD Text information will appear in the head unit's display. This includes ID3 tags on MP3-encoded discs played in the changer. With an optional XA-C30 Multi-changer adapter, you can control 3 changers with this head unit; with a series of multi-changer adapters, a total of 7 changers can be connected.

Custom File: When the unit is connected to a CD/MD changer with Custom File capability, you can locate discs in the changer by title by using this unit's List-Up function. While a disc is playing in the CD changer, its name will be displayed. By pressing the List button, you can display the names of the other discs loaded in the changer while still playing the original disc. When the desired disc is found, you can press Enter, and the selected disc is loaded and played.


Display Illumination/Clock Display: Pressing the Off button once will turn off audio output, but the clock display and face/button illumination remain on. This makes the clock display and face/button illumination "Keyed" instead of "Unit On" only. To turn the unit off completely, you must press the Off button for two seconds. Note: When installing in a vehicle without an accessory power wire at the radio location, you must turn the radio completely off (this defeats keyed operation), or you may wire the accessory power wire of this radio to an alternate source of accessory power to retain keyed clock and face/button illumination operation.
