Detailed description
Detailed description
Designed for the marine environment, the Clarion CMM-30 marine stereo source features a 76 mm (3-inch) color LCD screen with adjustable brightness control for optimal visibility. Its ergonomic interface, with clear text and backlit buttons, simplifies use in various lighting conditions.
Robust design and audio performance
The CMM-30 offers a waterproof design with an IP66 rating, ensuring resistance to water splashes and dust. It meets and exceeds industrial standards for salt fog (ASTM B117), UV exposure (ASTM D4329), and vibration resistance (3.0G), guaranteeing durability in marine environments. Its built-in amplifier delivers 4 x 25 watts RMS at 4 ohms, providing high-fidelity sound to two main zones. The unit features eight 3.5V RMS preamplified output channels, with selectable Zone 4 or subwoofer functionality. Power is supplied by 12-volt negative-ground electrical systems.
Extensive connectivity and multi-zone control
This unit supports a wide range of audio sources, including a global digital AM/FM tuner with integrated NOAA weather radio (US only). It is compatible with SiriusXM (requires a separate tuner, antenna, and subscription) and includes Bluetooth 5.0 audio streaming with Qualcomm aptX processing. A USB 2.0 port enables media playback and 2.1A charging, while an analog auxiliary input is also available. The CMM-30’s multi-source and multi-zone design allows independent volume and balance control across four distinct boat zones. Sound customization is possible via a 5-band equalizer or integrated tone controls (bass/mid/treble).
NMEA 2000 integration and ease of use
Certified NMEA 2000, the CMM-30 enables seamless integration and control with compatible multifunction displays (MFD) from brands such as Garmin, Lowrance, and Simrad. Its user interface is simplified with a single large rotary knob and backlit buttons, facilitating operation even in demanding marine conditions. It supports playback of MP3, WMA, FLAC, and WAV audio files and displays MP3 ID3 tag information (title/artist/album). The system is also expandable with optional wired Clarion marine remote controls (CMR-30, CMR-20, CMR-10).
