About the Sony CDX-GT400
Give your dash a custom look with the seven selectable display colors on Sony's CDX-GT400 CD player. You can set the display to match your car's interior, your outfit, or even your mood. The positive LED readout shows off system information in any kind of light, day or night. The detachable gunmetal faceplate blends well with any vehicle's interior, while the rotary control knob eliminates fumbling for tiny buttons while you're driving down the road.
Sony packed the CDX-GT400 with an array of audio features, so you can rest assured that the stereo will sound as good as it looks. It can play back your MP3- and WMA-loaded discs and even includes BBE MP processing to revitalize those compressed music files. Dynamic Soundstage Organizer raises the sound up to ear level, no matter where your car's speakers are located, while EQ3 gives you seven preset tone curves for tweaking the sound.

Drive S: The CDX-GT400 features the Drive S chassis platform. Drive S includes the CD mechanism, audio stages, 12 V power supply, and tuner section. The CD mechanism includes a suspension to resist shocks, a motor that draws less power, and a fast low-current pickup that improves durability and CD playback accuracy. 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.
Satellite Radio Ready: You can connect a satellite radio tuner to the CDX-GT400 in a couple of ways. The unit is directly compatible with the SIRIUS SIR-SNY1 Satellite Tuner for Sony (item # 607SIRSNY1). The Terk XMDirect universal XM Satellite Radio tuner (209XMD1000) can be connected to and controlled by the head unit when used with the XMDirect Smart Adapter for Sony (209SON110).
Note: In addition to the optional satellite tuner, you will also need the proper antenna and a subscription to SIRIUS or XM Satellite Radio.
Variable Color Display: The display backlight illumination can be adjusted to any of the following colors: light blue, blue, white (has a bluish tint), green, yellow green, red, or purple.
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-GT400 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/WMA Playback: This unit can play MP3/WMA files recorded on 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 playback, the unit displays any recorded ID3 Tag information.
EQ3: You may select one of the following EQ presets: Xplod, Vocal, Edge, Cruise, Space, Gravity, or Custom. For each preset, you can adjust the following frequencies: 60 Hz (Low), 1 kHz (Mid), and 10 kHz (High). The level of each frequency can be adjusted from +10 dB to -10 dB in 1 dB increments.
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.
Best Tuning Memory (BTM): This feature selects stations with the strongest signals within the selected band and stores them in order of their frequency.
2V Mono Subwoofer Preamp Outputs: In addition to the 2V front and rear preamp outputs, this unit includes one set of 2V 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.
Low-pass Filter: The subwoofer preamp outputs have a selectable low-pass filter that may be set to 78Hz, 125Hz, or off.
Front Panel Auxiliary Input: A front panel stereo minijack 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.
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 change the control direction of the remote, depending upon which side of the steering wheel you choose to mount the remote.
Compatibility: This unit is compatible with Sony Unilink CD/MP3 and MD changers.
Optional Auxiliary Input: You can connect an auxiliary audio device (such as a portable digital memory player, cassette, MiniDisc, or VCR) when used with the optional XA-300 Unilink Auxiliary Input Adapter. The XA-300 uses the Unilink and Bus Audio inputs on the back of the receiver, and allows you to connect an optional CD/MD changer in addition to the auxiliary audio source.
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.
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.
