Sony's brand-new CDX-4000X CD receiver Xplods on the scene with radical looks and powerful sound. The fold-down display is a blazing red and hot white, with red button illumination to match. The internal amplifier sends impressive power (19 watts RMS/50 watts peak x 4) to your speakers, while two sets of preamp outputs make it easy to add amplifiers.

Decode and display CD Text from encoded CDs. Selectable D-Bass pumps up the low frequencies (without affecting the mids and highs). The SSIR-EXA Adaptive Reception tuner improves radio reception dramatically. Round out your purchase with an optional wired remote control.

Why replace your factory radio?

Two good reasons - sound quality and cool features. A new car stereo offers power that's superior to most factory radios, along with more sophisticated tone controls. And most car stereos offer built-in or optional features that add safety and fun to life in your car, including inputs for your iPod or MP3 player, Bluetooth connectivity for hands-free cell phone calls, satellite radio or HD Radio reception, and connections for building an audio system in your car.

Features

Features

Display/Button Illumination: The main display line (which shows tuner frequency, track number, track time and text info), the D-Bass indicator and the menu navigation arrows (cross-key controls) are displayed with white illumination. The clock/source portion of the display, the CD in indicator, the the repeat indicator, the shuffle indicator and the D-Bass level are displayed with red illumination. The D-Bass button is backlit with green illumination, and all other buttons are backlit with red illumination.

Dual Info Display: There is a portion of the display that can be set to show the source name (FM1, FM2, CD, etc.) or the clock time while the main display line displays CD Text, the track number and elapsed time, or the tuner frequency.

Motion Display: When the tuner is activated, the display will automatically switch back and forth between the radio frequency and a whirling graphic. When a CD is playing, the unit will cycle through the CD track number and elapsed track time, the CD Text disc name (if any) and the CD Text track title (if any), with the whirling graphic being displayed between each display change.  The motion display can be turned off.

D-Bass with Auto Level Adjust: Instead of a standard loudness function, this unit has D-bass, which is controlled by a single button on the face of the unit.  D-bass uses a sharper curve than standard loudness to give you more bass without interfering with mids and highs.  Besides "off", there is D-Bass 1, 2 and 3, each of which give you progressively more bass.  As the volume level is increased, the D-Bass level is automatically reduced to ensure the bass boost doesn't overpower your speakers at high volumes.

Rotary Encoder Control with Cross-Key Control: This unit is equipped with a rotary control that turns like a conventional knob (for volume, bass, treble etc) and cross-key buttons (for seek and manual tuning, track advance and track search, etc) for easy, intuitive operation. There are four cross-key buttons; the four buttons are located  immediately above, below, to the left and to the right of the rotary encoder for convenient operation.

Flip-Down Face: The CD slot is located behind the flip-down face. The face is not motorized, so it must be manually pushed into it's viewing position after inserting/ejecting a CD.

CD Text Capable: When used with a CD Text CD, this unit will display the Disc Name, Artist Name and/or Track Name.

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.

SSIR-EXA Adaptive Reception: The SSIR-EXA tuner is equipped with "Adaptive Reception". The Adaptive Reception feature has two (IF AUTO and WIDE) for optimizing FM reception. The "wide" mode decreases the tuner's selectivity but results in better frequency response. The 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.

Source Tone Memory: Each source (AM/FM/CD) can store its own bass and treble levels.

Remote Compatibility: This receiver can be controlled by the optional wired rotary commander (item 158RMX4S).

Attenuator/Mute: The attenuate/mute function is accessible only by remote (wired remote sold separately).

Cellular Mute Lead: This unit is equipped with lead that mutes audio output when a cellular call is received, then restores the level once the call is over. To use this feature, you MUST have a cellular phone with a muting output that can be connected to the cellular mute lead.

Sound and Display Settings (can be changed by using the shift and set up button):

  • Clock (set clock time, clock displays on upper left hand portion of display)
  • Beep: Turns on/off the beeps that unit normally makes when a function is selected. This beep sound is from the internal amplifier ONLY, not the preamp outputs.
  • RM (Rotary Commander): Changes the control direction of the optional remote so they  correspond to where the remote is mounted (left or right of steering column).
  • D.INFO (Dual Information): Used to display the clock and play mode at the same time or to display the information alternately (OFF).
  • M.DSPL (Motion Display): Turns the Motion Display on or off
  • A.SCRL (Auto scroll): Automatically scrolls a disc or track name on a MiniDisc changer or a CD Text name in the head unit if it exceeds 8 characters.

CD Compatibility: This unit will play prerecorded CDs and finalized CD-Rs, but it will not play CD-RW discs.
