Marine CD receiver
Our take on the Clarion CMD7 by Crutchfield's Ken Nail
Why settle for a regular car stereo or an upgraded "marine" model when you can have a receiver that's built from the ground up for use in a boat? Clarion's CMD7 marine receiver is built to give you outstanding sound, while standing up to the tough marine environment. Rubber gaskets, a conformal-coated circuit board, and rigorous build quality all ensure that this receiver will entertain your crew for years to come.
Enlist your audio gear
The CMD7 is ready to play your tunes, however you like them. The rear USB input provides a connection for thumb drives or your iPod® while the rear auxiliary input adds another option for portable players. Many boaters love the variety and range of satellite radio — you can add an optional tuner and enjoy all the variety it gives you.
And don't forget your discs — the CMD7 plays all your store-bought or home-burned CDs, as well as discs loaded with MP3 and WMA files. Whatever your source, you'll be able read all the song and artist info clearly — even in bright sunlight — courtesy of the 2-line black-on-white display. A 3-band EQ lets you tailor the tone to your taste, and you can turn your system into a heavy-hitting cruiser by adding amps to the two sets of preamp outputs.
Remote control ready
You can add a wireless remote control to your system, or add on Clarion's MW1 and MW2 wired remote controls — place one at the helm and you'll still be able to control the receiver that you've installed below. Or pick up Clarion's MF1 and enjoy radio frequency remote control of the recevier wherever you are on the boat.

Marine Tested: The Clarion CMD7 Marine CD receiver has been engineered and tested for use in the harsh marine environment. The receiver meets or exceeds ASTM B117 Salt/Fog Exposure and ASTM D4329 UV Exposure standards. The CMD7 offers full IPX5 tested and certified Water Intrusion protection. The faceplate features a unique rubber gasket and door assembly offering the internal components complete water protection. The unit features a sealed stainless steel chassis, a front panel rubber gasket and drip shield over the wire connections to keep water from dripping onto the internal circuits, behind the faceplate and wire connections. The receiver also features a HumiSeal coated PCB to protect against corrosion. This means the main circuit boards feature a silicone coating to help resist the effects of humidity.
Oversized Fold-Down Face: The CMD7 features an oversized fold-down face with a rubber surround so your CD-disc stays protected behind the unit's marine rated face-plate. The front panel mechanically folds down to load and eject CDs. The unit's face features a high visibility 2-line display.
Note: The face-plate is not detachable.
Contrast: You can set the contrast level between 1 and 10 for best display visibility.
Illumination Dimmer: The receiver's display automatically dims to a preset brightness when the boats lights are turned on. The wiring harness includes an orange/white lead that should be connected to the boats 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 then the display returns to the screen saver display.
MOSFET Amplifier: The Clarion CMD7 is equipped with a MOSFET amplifier. Compared to conventional power supplies, the MOSFET amplification circuit is smaller and more efficient, and it delivers increased power with less distortion and absolutely zero on/off switching noise. More power means louder and cleaner music at higher volumes because you're not pushing the limits of the amplification circuit.
CEA2006 Compliant: The power specifications for the CMD7 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 CMD7 are as follows:
- CEA2006 Specs: 19 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 45 watts x 4 channels (200 watts total)
BeatEQ: In addition to providing 3 preset equalization patterns (Bass Boost, Impact, and Excite), Clarion's BeatEQ lets you freely customize the level and range of the bass, midrange and treble portions of each pattern. You can tune the sound to your liking, depending on the category of music, for a more fulfilling listening experience.
- Bass Boost: Bass is emphasized +/-3.
- Impact: Bass and treble are emphasized +/-3.
- Excite: Bass, midrange, and treble are emphasized +/-3.
- Custom: Adjusts the bass, midrange, and treble
- Bass: You can set the effected bass frequency to 60Hz, 80Hz, 100Hz, or 200Hz and the Q-factor to 1.0, 1.25, 1.5, or 2.0
- Midrange: You can set the effected midrange frequency to 500Hz, 1.0kHz, 1.5kHz, or 2.0kHz and the Q-factor to 0.5, 0.75, 1.0, or 1.25
- Treble: The effected treble frequency can be set to 10kHz, 12.5kHz, 15kHz, or 17.5kHz; the Q-factor is fixed
- Off (Flat): Bass, midrange, and treble are set to 0.
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.
4ch/2V Preamp Output: The Clarion CMD7 features 4ch/2V RCA line level outputs (Front, Rear/SW). The unit's rear preamp outputs can be configured as a dedicated non-fading RCA subwoofer output with a low-pass filter and level control (+/-6).
Beep: The headunit provides an audible beep to confirm button operation. This function can be turned On or Off.
AM/FM Tuner: The CMD7 features a built-in AM/FM tuner with U.S. and European tuning.
Tuning Modes: The built-in tuner offer 3 tuning modes - Seek, Manual, and Preset.
Preset Tuning: The CMD7 provides 3 FM banks and 1 AM bank. Each AM/FM bank can hold up to 6 station presets, proving you with 18 FM station presets and 6 AM station presets. Stations can be stored manually or automatically.
Preset Scan: Preset scan receives the stations stored in the headunit's preset memory in order. This function is useful when searching for a desired station in memory.
Satellite Radio Ready: There are several options for connecting an optional XM or SIRIUS Satellite Radio receiver to this receiver:
- Sirius Satellite Radio: To receive Sirius Satellite Radio, you can connect the optional SC-C1 Sirius Connect Universal Vehicle Tuner (607SCC1, sold separately) directly to the headunit's Sirius direct connection (no proprietary interface required).
