About the Sony CDX-M7815X

If you're looking for a CD receiver to quarterback your mobile audio system, Sony's CDX-M7815X has you covered. It comes loaded with three sets of 4-volt preamp outputs that send plenty of clean signal to your amplifiers, including a dedicated subwoofer output for total command over the low frequencies.

If you're looking for a CD receiver to quarterback your mobile audio system, Sony's CDX-M7815X has you covered. It comes loaded with three sets of 4-volt preamp outputs that send plenty of clean signal to your amplifiers, including a dedicated subwoofer output for total command over the low frequencies.

Built-in high- and low-pass filters let you tailor the frequencies to match your speaker system. And with its full-motion display and motorized faceplate, you get a stylish receiver that will look good in any car.

Contour the sound with EQ7, which offers seven preset tone curves and a 7-band equalizer for maximum sonic control. BBE MP processing (exclusive in Sony receivers) is also on hand to revitalize your compressed digital music files. And you won't have to suffer through distant, dull sound ever again — Dynamic Soundstage Organizer enhances your vehicle's soundstage to make you feel like you're sitting right in the middle of the band!

Worried about your entertainment options? No problem. The CDX-M7815X can handle both MP3 and ATRAC3plus file formats, and Sony's "Aux Lite" auxiliary input lets you add a portable player or add-on satellite radio tuner to the CD changer input without an adapter.

Features

Drive S HX: The CDX-M7815X features the Drive S HX chassis platform. Drive S HX includes the CD mechanism, audio stages, 12 V power supply, and tuner section. The CD mechanism includes an improved suspension to resist shocks, a new motor that draws less power, and a fast new low-current pickup that improves durability and CD playback accuracy. The Drive S HX chassis also employs advanced high capacity audio capacitors for improved audio signal stabilization. The 52W x 4 S-MOSFET Power IC produces clearer, more accurate sound, less distortion, and a higher signal-to-noise ratio than previous designs.

Full-Motion Fluorescent Display: The unit's 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 130(H) x 39(V). Using the Image button on the face of the unit, you can cycle through 3 wallpaper displays, 5 spectrum analyzer displays, and 2 motion displays. Using the Auto Image function, you can step repeatedly through the spectrum analyzer displays, motion displays, or all displays.

24-Bit Burr Brown D/A Converter: This digital-to-analog converter uses Advanced Segment architecture to achieve improved dynamic performance and resistance to clock jitter. Additionally, the digital-to-analog converter features a zero-bit detection circuit, which senses when all bits are low on a CD, and mutes the output for improved S/N ratio.

ATRAC CD Playback: The CDX-M7815X plays ATRAC3plus/ATRAC3 files recorded on CD-R and CD-RW discs. Each ATRAC disc can have a maximum of 255 groups and 999 files.

MP3 Playback: This unit can play MP3 files recorded on CD-ROM, CD-R, and CD-RW discs in ISO9660 Level 1/Level 2, Joliet, and Romeo formats. Each disc should have a maximum of 150 folders and 300 files/folders. During MP3 playback, the unit displays any recorded ID3 Tag information.

BBE MP: When playing back MP3 files, the BBE MP circuit recovers and recreates harmonics, restoring the detail, warmth and nuances that existed in the original recording.

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.

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.

XM Satellite Radio Controls: This unit can control an optional Sony XM tuner. The optional tuner, along with an antenna and subscription, will allow you to receive XM Satellite Radio. XM Satellite Radio programming features over 130 channels of programming beamed coast-to-coast, including 68 channels of commercial-free, digital-quality music, and more than 60 channels of news, talk, sports, entertainment, children's programming, and information.

SSIR-EXA Adaptive Reception: The SSIR-EXA tuner is equipped with "Adaptive Reception". The Adaptive Reception feature has two modes ("IF Auto" and "IF 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.

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 in length to each tuner preset station. Station Memos can be used with the List-up function to locate a station.

4 V Mono Subwoofer Preamp Outputs: In addition to the 4 V front and rear preamp outputs, this unit includes one set of 4 V mono subwoofer preamp outputs. Although there are two female RCA subwoofer outputs, the same signal is carried by both connections. A low-pass filter (see below) can be used to filter high frequencies from the signals output by the subwoofer outs.

High-pass Filter: The front and rear preamp outputs have a selectable high-pass filter that may be set to 78Hz, 125Hz, or off.

Low-pass Filter: The subwoofer preamp outputs have a selectable low-pass filter that may be set to 78Hz, 125Hz, or off.

Aux Lite Auxiliary Input: The CDX-M7815X 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).

Dimmer: This unit is equipped with a wire that Sony calls an illumination lead, however, it acts as a dimmer lead. When the dimmer mode is set to "Auto" and the illumination lead receives power, the display dims to a preset level. The display brightness is not affected by the vehicle's dimmer control. Also, the dimmer feature may be turned off, so dimming does not take place when the illumination lead receives power. You may choose to dim the display at all times by setting the dimmer mode to "On".

Note: For this feature to work, the unit's illumination wire must be connected to your vehicle's dash lights wire.

45-Degree Installation: For flexibility of installation, this unit can be mounted between 0 (horizontal) and 45 degrees.

Wired Remote Compatibility: In addition to the supplied wireless remote, the receiver can be controlled by an optional wired rotary commander (item 158RMX4S). Once the wired remote is connected, you can use the menu system to change the control direction of the remote, depending on which side of the steering wheel you choose to mount the remote.

Changer Controls

Compatibility: This unit is compatible with Sony Unilink CD/MP3 and MD changers. In addition, this unit can control compatible Sony Mobile Memory Stick players.

Multiple Changer Control: A maximum of 5 CD changers, 5 CD/MP3 changers, or 5 MD changers may be connected to this receiver. When connecting CD, CD/MP3 and MD changers, you may connect up to a total of 7 changers (but there must not be more than 5 of one type of changer). When connecting more than one changer to this receiver, you must use the Sony XA-C30 source selector.

CD Text/MD Memo Display: When used with a compatible CD changer and a CD Text encoded CD, this unit will display the CD Text information. When using a compatible Sony MD changer, this receiver can display disc and track names that have been prerecorded on MDs.

Disc Memo: When a changer with the Custom File function is connected to this unit, you can enter names, up to 8 characters long, into memory for up to 110 discs. After a disc has been given a custom title, you may search for the disc, by title, using the List-up function.

Auto Scroll: If the text being displayed exceeds 8 characters and the Auto Scroll function is on, the information will automatically scroll across the screen.

Note

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.
