Media connectivity
Bluetooth aptX® for
high quality streaming

Dual zone audio with fixed output
With this function, it is possible to split your boat into two discrete zones to enjoy different volume levels of entertainment. 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 an optional external volume control device. This is ideal for separate areas such as salons, wakeboard towers, and open bows.


Enjoy interactive Pandora® internet radio anytime anywhere
Pandora internet radio is at home in your boat. The source unit’s Pandora feature works together with the Pandora app on your smart device. Play songs while you feedback a “thumbs up” or “thumbs down” which is reflected in future selections. The Pandora app lets you bookmark Artists/Songs or even create your own station to customize your marine music experience.

SiriusXM Satellite Radio with optional tuner (SXV200 and SXV300)


Connect, control and enjoy SiriusXM Satellite Radio on your boat. With commercial-free music from every genre, sports, news and talk, all available 24/7, you can bring the hottest entertainment onboard and have a cool time cruising.    


Global radio tuner with weather band
The built-in multi-band tuner supports reception of radio stations just about anywhere in the world — which is nice when you’re sailing around the globe or just across the gulf. 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.


Front AUX input for convenient connection
With AUX input connectors right on the front of the unit, it’s extremely easy to hookup an external audio source for enjoyment through your boat’s audio system.    


3-Band EQ for customizable sound
In addition to providing 3 preset equalization patterns — BASS BOOST, IMPACT, and EXCITE — Clarion’s 3-Band EQ even 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 personalized and fulfilling listening experience.


Low Pass Filter for subwoofer
Switching on the Low Pass Filter (LPF) will send only the low frequency range through specified outputs to ensure superb performance when connected to a subwoofer.    

6-channel 4-volt RCA outputs make it easy to expand and upgrade
Equipped with 6-channel line outputs, you have independent controls over each channel for amplification. Front and rear speakers will retain fader and balance control while the subwoofer levels can be adjusted from the source unit for on the fly adjustments.
