If you just want to play CDs and listen to the radio, this no-nonsense stereo offers great sound, simple controls, and easy-to-use features. But if you want to build a system, this versatile Clarion is ready to rock with all the connections and options you'll ever need.

Entertainment choices
Pop open the door on the right hand side of the CZ309's front panel, and plug your iPod® into the USB input. Now you can use the receiver's controls to run your iPod, and view song titles on its bright 8-character display. You'll also find an auxiliary input behind the door that'll accept audio from a satellite radio, MP3 player, or any other portable. In addition, the CZ309 works with a Clarion satellite radio tuner or CD changer.

Sweet sound
The built-in amplifier delivers plenty of power, while a bass enhancer and 2-band parametric equalizer allow you to adjust the sound to your taste. Three sets of preamp outputs come in handy if you're adding outboard amplifiers, and you'll appreciate the subwoofer volume control when you're switching from one music genre to another, like from rock to hip-hop. Use the built-in high- and low-pass filters to get maximum efficiency from your speakers and subs.

More options
Clarion's optional BLT370 Bluetooth® adapter mutes the music when you get a call, so you can carry on the conversation over the car speakers and keep your hands on the wheel. You can also add an adapter that enables your vehicle's steering wheel audio controls to run the CZ309. Clarion includes a wireless remote so your passengers can choose the tunes while you concentrate on driving.

iPod note: If you're going to use your iPod with this receiver, be sure to check "Details" for specific iPod model compatibility with this receiver or its optional iPod adapter.

    Features

    Overview: The Clarion CZ309 is an AM/FM/CD receiver that can play MP3, WMA, and AAC audio files on CD-R and CD-RW discs; and supports ID3-Tag, as well as CD Text. It also has a front-panel 3.5mm auxiliary input for connecting a portable audio device and a front-panel USB type-A port for connecting your USB mass storage audio device or iPod. Additional accessories that are compatible with this unit include Bluetooth Audio and Bluetooth Telephone (when the optional Clarion Bluetooth adapter is connected); Satellite Radio (via an optional tuner kit); multi-disc CD-changer (sold separately); and an optional steering wheel remote interface (sold separately) which allows you to keep your factory steering wheel controls.

    CEA2006 Compliant: The power specifications for the CZ309 are compliant with the CEA2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Electronics Association (CEA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers. The power output specs for the CZ309 are as follows:

    • CEA2006 Specs: 20 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
    • Maximum Power Output: 50 watts x 4 channels (200 watts total)

    Ergonomic Face Design: The Clarion CZ309 features an easy-to-use rotary volume control and easy-to-read illuminated buttons on the face which are laid out in an asymmetrical design to place the most used features within a specific area for ease of use and less user distraction. The front panel 3.5mm auxiliary input and USB input on the CZ309 makes it easy to connect external audio devices.

    Digital LCD Display: The single-line digital LCD display, with black background and white characters, on the CZ309 allows numbers and characters to be displayed clearly in all lighting conditions.

    MP3/WMA/AAC Playback: The unit can play MP3, WMA, and AAC files recorded onto CD-R and CD-RW discs using ISO9660 Level 1 or 2, Joliet, Romeo, or Apple ISO formats. The player can recognize up to 8 hierarchical levels, 255 files per folder and 510 total files. Bit rates for MP3 and AAC are 8-320 kbps, plus VBR (Variable Bit Rates). Bit rates for WMA are 8-320 kbps. This unit is compatible with, and will display MP3 and WMA ID3 tags up to 64 characters.

    Note: Tracks purchased at an iTune Music store, and copyright-protected files cannot be played.

    Auxiliary Input: The CZ309 features a front panel 3.5mm auxiliary input so you connect your external portable audio player or portable satellite radio receiver to this headunit. You can adjust the Auxiliary input sensitivity level from Low, Mid, to High to match the volume output of your connected external audio device.

    Three 2-Volt Preamp Outputs: The CZ309 is equipped with a pair of 2-volt front, rear and subwoofer preamp outputs. You can fade between the front and rear preamp outputs, while the subwoofer preamp output is non-fading.

    Built-in Crossovers: The headunit's built-in high pass crossovers let your front and rear speakers reproduce the proper frequencies (120Hz or Full-Range) for natural sound and efficient power handling. A low pass filter with selectable frequencies of 50, 80 or 120Hz, coupled with a Subwoofer Level Control of -6 to +6 allow full adjustment and control of a subwoofer for maximum performance.

    Amp Canceller: If you choose to connect the receiver to external amplifiers, you can turn off the built-in amplifier for better sound quality.

    Z-Enhancer Plus: Z-Enhancer Plus features five equalization selections (B-Boost, Impact, Exite, Z+Flat and Custom). Along with 2 bands of parametric equalization, the Z-Enhancer Plus circuitry enables sound adjustments with more flexibility than the basic Bass and Treble tone controls.

    • B-Boost: Bass is emphasized from -3 to +3.
    • Impact: Bass and treble are emphasized from -3 to +3.
    • Excite: Bass, treble and midrange are emphasized from -3 to +3.
    • Z+Flat: Bass and treble settings are set to flat.
    • Custom: Adjusts the bass and treble independently from -7 to +7 (-14 to 14dB). You can set the effected bass frequency to 60, 80, 100, or 200 Hz and the Q-factor to 1, 1.25, 1.5 or 2.0. The effected treble frequency can be set to 10k, 12.5k, 15k, or 17.5k.
    • Off: No sound effect.

    Magna Bass EX (Extend): The Magna Bass Extend feature does not adjust the low frequencies like the normal sound adjustment function, but emphasizes the deep bass frequencies to provide you with a dynamic sound. This circuit boosts bass at an ultra-low frequency of about 50Hz, creating a rich, deep, defined bass rather than the muddy, booming bass of a standard loudness control. What is more, boost levels are dependent on the system volume, resulting in balanced system response and dynamic bass reproduction.

    Disc-In-Play-Function: This feature allows you to turn the power to the unit "on" and start playing the disc automatically when the disc is inserted even if the unit is not powered up, as long as the ignition key is turned to the "on" or "acc" position.

    Scan Play: This function allows you to locate and play the first 10 seconds of all the tracks recorded on a CD or the first 10 seconds of the first track of all the folders on an MP3/WMA disc.

    Last Position Memory: If you turn off the unit while a disc is playing, it will resume playback at the stopping point when it is turned on 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.

    Title Entry: Titles up to 8 characters long can be stored in memory and displayed for CD, CD changer, Radio stations and TV stations. The number of titles that can be entered for each mode are as follows - 50 disc titles for CD Mode, 20 station titles for TV mode, 30 station titles for Radio Mode, and 100 disc titles for Changer mode.

    Instant Station Recall (ISR): You can store one radio station in Instant Station Recall (ISR) memory and recall it from any mode (except Power Off). Once the ISR station has been recalled, you cannot tune to another station without first disengaging the ISR function. You can, however, switch to another source.

    Illumination Dimmer: The receiver's display automatically dims to a preset brightness when the vehicle's headlights are turned on. The wiring harness includes an orange/white lead that should be connected to the vehicle's parking light circuit in order for the dimmer feature to operate.

    Screen Saver: This unit is provided with a Screen Saver function which allows you to show various kinds of patterns and characters in the operation status indication area of the display in a random order. You can turn this function on or off. If the button operation is performed with the screen saver function on, the operation display corresponding to the button operation is shown for about 30 seconds and the display returns to the screen saver display.

    Message Information: You can enter a message up to 30 characters long in the unit's memory and display it as the receiver's screen saver.

    Wireless Remote: The CZ309 comes supplied with the RCB-176 infrared wireless remote control for wireless operation of the CD player. The remote measures 1.715" wide x 0.495" tall x 4.465" long.

    OEM Remote Ready: The unit also features an OEM steering wheel remote control input on the rear of the unit to allow you to keep your vehicle's radio steering wheel remote controls and/or rear seat radio controls when used with the optional SWI-JACK interface adapter (127SWIJACK, sold separately). The SWI-JACK is compatible with over 95% of the vehicles made from 1986 to the present. Compatible vehicles include many Acura, Audi, BMW, Buick, Cadillac, Chevrolet, Chrysler, Dodge, Ford, GMC, Harley Davidson, Honda, Hummer, Hyundai, Infiniti, Isuzu, Jaguar, Jeep, Kia, Land Rover, Lexus, Lincoln, Mazda, Mercury, Mini, Mitsubishi, Nissan, Oldsmobile, Plymouth, Pontiac, Saab, Saturn, Scion, Suzuki, Toyota, and Volkswagen vehicles. Please consult "Outfit My Car" to see if your vehicle is compatible.

    Detachable Face Security: This unit features Detachable Face Security. A face-fixing clip is supplied for making the face non-detachable, if desired. The unit comes with a hard plastic face case to store the receiver's faceplate when detached.

    Mounting: You can install the unit within 30-degrees of horizontal. When ISO-DIN mounting, you will need to use your vehicle radio's original factory ISO screws.

    External Device Controls

    USB Port: The front-panel USB port allows you to connect and play USB Mass Storage devices loaded with MP3,WMA, and AAC files. This unit is compatible with USB 1.1/2.0 with maximum data transfer rates of 12mbps. MP3, WMA, and AAC files with a bit rate of 8-320 kbps, formatted in FAT or FAT32 are supported. The headunit can recognize up to 8 hierarchical levels, 255 files per folder and 510 total files. Titles up to 64 characters can be displayed while in USB mode.

The CZ309 offers two iPod playback modes (your iPod's control will be locked when connected to the CZ309) - Play Mode and iPod Menu Mode. During Play Mode you can control the following playback functions of your iPod: Skip Tracks, Fast-forward/backward, Pause, Repeat, Random and Cancel. The iPod Menu Mode allows you to select music for playback from your iPod by category (Playlist, Artist, Album, Song, Genre, or Composer). You can select between categories by using the headunit's numbered preset buttons 1-6. Once you have selected a category, you can search through the tracks in that particular category alphabetically.
