Our take on the Clarion ProAudio DXZ645MP

Jazz up your dash with a flash of color! The fold-down face on Clarion's DXZ645MP CD receiver frames a dot-matrix display that provides you with information in any one of 80 colors. Turn on "Color Scan," and the display cycles through all the colors. And that's not all — the button illumination changes with the display color, for a completely cohesive look. Cool!

When you're not listening to your MP3 or WMA tunes, jam to the Magi-Tune+ tuner. It pulls in local stations and far-off weak signals with ease. When you tire of earthbound radio, controls for a SIRIUS satellite radio tuner module are your gateway to more than 120 channels of top-notch entertainment for just $12.95 per month. Check out 65 channels of totally commercial-free music, which feature an incredible variety of songs from a wide range of genres. You'll also get news, talk, sports, and entertainment, including round-the-clock traffic/weather updates for major metropolitan areas and broadcasts of NFL, NBA, and NHL games. (Satellite radio service is available only within the lower 48 states — not available in Alaska, Hawaii, or U.S. territories.) Subscribers can also take advantage of free online streaming of all SIRIUS music.

Add any other source you need with the DXZ645MP's auxiliary input and Clarion's TV tuner/DVD/CD changer controls for truly customized options.

Modify the sound with the four Z-Enhancer+ preset tone curves. Magna Bass EX gives your music a serious dose of low-frequency stimulation when you need the extra "thump." As a ProAudio model, the DXZ645MP comes with a reassuring 2-year warranty.

And don't let that sound control and high-octane 4-way power go to waste. Replacing your factory speakers with superior aftermarket speakers can make a dramatic improvement in your audio system's overall sound.

Changer Controls


Message Display: When you turn the unit on, the display shows a message stating "Hello". When the unit is turned off, "Good-bye!" appears on the display. The message display can be turned on or off.

Variable Color Display: The display backlight and button illumination can be adjusted to any of 80 colors. The following color presets are stored in memory: Red, Mandarin, Orange, Amber, Yellow, Yellow Green, Lime, Green, and Dark Green. In addition, you can store 1 custom color under the User preset. The custom color can be selected by adjusting the red and green values. If Color Scan is selected, the display will automatically cycle through all the available colors.

Adjustable Contrast: You can adjust the display contrast to match the angle of installation of the unit. The contrast setting can be adjusted from 1 to 16.

Screen Saver Display: You can choose "SS On", "SS Off", or "SS Message". In "SS Message" mode, the unit displays a 30-character message that you can edit. The default message reads "Welcome to Clarion".

SIRIUS Satellite Radio Controls: This unit can control the optional Clarion SIRIUS Satellite tuner (sold separately). The optional tuner, along with an antenna and subscription, will allow you to receive SIRIUS Satellite Radio.

Clarion CeNET TV Tuner Control: This unit is capable of controlling Clarion's CeNET TV tuner.

Clarion CeNET DVD Deck Control: This unit is compatible with Clarion's CeNET DVD deck.

Z-Enhancer Plus: The Z-Enhancer function features four types of sound tone effects stored in memory. You may select "Bass Boost" (bass emphasized), "Impact" (bass and treble emphasized), "Excite" (bass and treble emphasized, mids de-emphasized), or "Custom" (allows you to fully adjust bass and treble). When "Bass Boost" is selected, you can adjust the bass setting from -3dB to +3dB in 1dB increments. When "Impact" or "Excite" is selected, you can adjust the bass and treble settings from -3dB to +3dB in 1dB increments. When "Custom" is selected, you can independently adjust the gain, frequency and Q factor for the bass. For the treble, you can adjust the gain and frequency.

Magna Bass EX: The Magna Bass EX feature provides an extra boost of bass when activated. The effect of the Magna Bass EX varies with the volume level.

Dual-zone Capability: You can select separate audio zones for the front and rear seat passengers. The Main Zone is the source unit's regular front and rear channels, while the Sub Zone is a dedicated RCA line-level output for use with an external amplifier, headphones, or powered speakers. The Main Zone can be the tuner, internal CD player, or aux input. The Sub Zone can be the audio from any device connected to the CeNET input or aux input. By pressing a front panel button, the zones can be reversed.

Note: Only sources connected to the aux input can be used in both zones simultaneously.

Magi-Tune+ FM Tuner: This receiver is equipped with Clarion's proprietary Magi-Tune+ FM Tuner, which improves sensitivity and selectivity for excellent FM stereo reproduction.

Instant Station Recall (ISR): This feature gives you one touch recall of a single favorite radio station (this is in addition to the 18 FM and 6 AM presets).

CD/CD Changer/Tuner/TV Titling: Titles, up to 10 characters long, can be stored and recalled from memory for individual CDs, discs in a changer magazine, radio stations, and TV stations. 50 titles may be entered for the CD mode, 20 may be entered for TV tuner mode, and 30 may be entered for radio mode. In CD changer mode, you may enter 100 CD titles when using the DCZ625, 100 CD titles when using the CDC655Tz, or 50 titles when using the CDC1255z changer.

MP3/WMA Playback: This unit can play MP3 and WMA files recorded on CD-R and CD-RW discs in ISO9660 Level 1/Level 2, Joliet, or Romeo formats. MP3 files with bit rates from 8 kbps to 320 kbps and WMA files with bit rates from 48 kbps to 192 kbps are supported.

Top Play Button: Pressing the "Top" button while a CD is playing will start the disc playing from track 1 again.

Auto Reload: When a CD is ejected and left sticking out of the CD slot for 15 seconds, the unit automatically reloads the CD to protect if from damage. This feature works with 5" (12cm) CDs, but it will not work with 3" (8cm) CDs.

Non-Fading Preamp Outputs: In addition to the front and rear preamp outputs, this unit is equipped with one set of non-fading RCA preamp outputs. These outputs have a selectable low-pass filter that can be set to 50Hz, 80Hz, or 120Hz. You can adjust the subwoofer volume from -6 dB to +6 dB in 1 dB increments.

Auxiliary Input: Stereo RCA preamp inputs are hardwired to the back of the unit on a 3" lead, allowing you to connect 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 Aux input sensitivity is adjustable and can be set to High, Mid, or Low.

Dimmer Feature: This unit is equipped with a wire that Clarion calls an illumination lead, however, it acts as a dimmer lead. When the illumination wire of this unit receives power and the dimmer feature has been turned on, the display will dim to a preset level.

Note: When the power and constant wires are connected and the illumination wire is supplied with voltage (when you turn your lights on), the button illumination remains on even if the unit is turned off completely.

Anti-theft Indicator: A red indicator will blink on the unit after the faceplate is removed. This feature can be turned On or Off.

Changer Controls

CeNET Control: This unit is equipped with a CeNET control connector and can control up to a total of two CeNET changers (CD and/or MD). Two changer control requires a Y-adapter (sold separately).

CD Title Memory: When used with a compatible CD changer, this feature allows you to assign names to discs in the changer. Each name can be up to 10 characters in length. The number of names you can store depends on the CD changer that is connected to the head unit. 


Display Illumination/Clock Display: When the clock display has been given priority, pressing and holding the power button turns off audio output, but the clock display and face illumination remain on. When the clock display has not been given priority, pressing and holding the power button turns the unit off completely. This unit's face illumination and clock are "keyed" only when the clock display has been given priority.

Warranty Note: For 2004 ProAudio models, Clarion has extended the 2-year warranty to all Crutchfield customers, even if the unit is not installed by an authorized Clarion dealer.
