About the Clarion M508
Merrily, merrily down the stream (-ing music)
Merrily, merrily down the stream (-ing music)
Clarion's M508 digital media receiver lets you stream music from your smartphone or any Bluetooth device to your boat's sound system. Bluetooth aptX processing (also found in many Android smartphones) restores the sparkle that's lost during compression, so you'll enjoy much better sound quality.
Shape your sound your way
Clarion built this rugged marine receiver to last, but it's also designed to deliver outstanding sound. The 3-band parametric equalizer lets you adjust the highs, mids, and lows to suit your preferences, and you can use the built-in frequency filters and subwoofer controls to get the best possible performance from your system. You'll find the four sets of preamps handy if you're adding amplifiers to your sound system.
Dual zone control lets you split the boat into two distinct areas to suit your needs, one zone powered by the radio and the second by an external amp (sold separately). You'll be able to crank up the bow speakers and leave the cabin speakers at a more conversational level.
Make the most of your music sources
The M508 gives you mastery over your music collection. If you're a Pandora® Internet radio fan, you can listen to your favorite stations when your iPhone's connected via USB. Song and artist information shows up clearly on the sharp-looking black-on-white 2-line display.
If you've ripped your entire CD collection and gone digital, you can plug a thumb drive into the front USB port and enjoy all your favorite MP3 or WMA tunes, or you can play your digital music player through the handy front AUX input. You can also enjoy the vast array of programming on satelllite radio by connecting a SiriusXM tuner (sold separately, subscription required).
Tune into terrestrial radio
Clarion's excellent AM/FM tuner hauls in plenty of local radio stations, no matter where in the world "local" might turn out to be. You'll also be able to get the latest on changing conditions from the Weather Band.
The black-on-white face makes it easy to see what you're tuned into at the moment, and the controls make changing channels or sources a breeze, even when you're underway.
Clarion has earned its reputation for building marine electronics tough enough to withstand salt water, heavy fog, blistering sunlight, and lashing rain. The M508 is a versatile, multi-source receiver that's tough enough to handle the extremes of a marine environment.

Marine Tested: The Clarion M508 Marine digital media receiver has been engineered and tested for use in the harsh marine environment. The M508 meets ASTM B117 and ASTM D4329 guidelines ensuring the receiver's resistant to salt, fog and UV exposure. The receiver features a drip shield chassis to keep water from dripping onto the unit's internal circuits. In addition, the head unit's PCB and microprocessor are conformal coated to protect them from corrosion. It also has low power consumption when powered off.
High Visibility LCD: The two-line, 13-digit, high visibility LCD (with bluish white background and black characters) on the M508 allows numbers and characters to be displayed clearly in almost any lighting condition. The display's backlight brightness can be set to High or Low. You can turn the display's backlight off in the event the display is too bright in different lighting conditions.
Water Resistant Covers (optional): Even though the conformal coating makes the receiver water-resistant, it is still recommended that it be used with a universal marine cover (sold separately - see Accessories Tab)
Optional Wired & Wireless Remotes: The unit is equipped with a rear mounted 8-pin DIN connector to accommodate optional Clarion wired & wireless remote controls.
- Wired Remote: The MW1 and MW3 (sold separately) are hardwired remote controls with an LCD screen. The MW4 (sold separately) is a more advanced wired remote with a 2.8" color LCD screen.

And with Weather Band you'll always have the latest weather updates, including automatic reception of emergency weather information to keep your voyage as smooth as possible.
- AM/FM Radio: The Clarion M508 is equipped with a
built-in AM/FM tuner offering manual, seek, and preset tuning (with preset
scan). 18 FM station presets and 6 AM station presets can stored; stations
can be stored manually or automatically. Preset scan lets you quickly scan
through all of your preset stations in a selected band. This function is
useful when searching for a desired preset station. When Local seeking is
turned "On", only those radio stations with strong radio signal can be
received. This unit's tuner is initially set to USA frequency intervals, but
can be changed to Europe, Australia, and other countries tuning.
- USA: FM (87.9-107.9 MHz) / AM (530-1710 kHz)
- Europe: FM (87.5-108.0 MHz) / AM 531-1602 kHz)
- Australia/Other Countries: FM (87.5-108.0MHz / AM (531-1629 kHz)
- Weather Band: Weather Band channels include - CH1 (162.400MHz), CH2 (162.425MHz), CH3 (162.450MHz), CH4 (162.475MHz), CH5 (162.500MHz), CH6 (162.525MHz), & CH7 (162.550MHz).
MOSFET Amplifier: The Clarion M508 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. The power output specs for the M508 are as follows:
- CTA-2006 Specs: 18 watts RMS x 4 channels (at 4 ohms, 20Hz-20kHz, 1% THD-N)
- Maximum Power Output: 50 watts x 4 channels (200 watts total)
Note: The power specifications for the M508 are compliant with the CTA-2006 Mobile Amplifier Power Testing and Measurement standards from the Consumer Technology Association (CTA). These standards were developed as a way to equitably compare power specs from model to model and between manufacturers.
4V/6Ch RCA Outputs: With 6-Channel/4-Volt RCA Outputs, you are free to add external power amplifiers to create a more powerful, sophisticated audio system. What's more, the 4-volt output assures a pure, high quality signal for your entire sound system. The non-fading subwoofer preamp output features an independent level control (0-12).
3-Band EQ + Presets: The Clarion M508 incorporates a 3-band EQ and 11 EQ presets. The EQ presets consist of Flat, Jazz, Pop, Classic, Rock, News, Urban, Rave, Movie, Techno, and User. The User preset allows you to adjust the head unit's 3-band EQ (Bass, Mid, & Treble) from -7 to +7. EQ settings are applied to all sources.
Dual Zone Audio with Fixed Output: The Clarion M508 is fitted with a stereo line-level output (fixed) for Dual Zone audio (requires an external amplifier in Zone 2). With this function, it is possible to split your boat into two discrete zones to enjoy different volume levels of the same audio source. For instance, the bow can be tuned-in to a higher volume level for enjoyment in the wind while the stern can enjoy the music at a lower volume to accommodate conversations. Volume levels from the fixed zone are controlled by optional external volume control device (such as the 142RLC - sold separately). This is ideal for separate areas such as salons, wakeboard towers, and open bows.
Beep Confirmation: The marine head unit provides an audible beep to confirm button operation. This function can be turned On or Off.
