Detailed description

The Clarion CMM-20 marine stereo source unit is a source unit designed for marine environments, offering versatile audio features and construction suited to harsh conditions. It integrates an amplifier capable of delivering 4 x 25 watts RMS at 4 ohms, for a total output of 100 watts.

Connectivity and audio sources

The CMM-20 offers various audio playback options, including a global digital AM/FM tuner and NOAA weather radio for US users. Wireless audio streaming is provided via Bluetooth® 5.0, offering a connection range up to 11 meters. A USB 2.0 input is available, allowing playback of formats such as MP3, WMA, FLAC and WAV, as well as a 1A charging output for mobile devices. The unit also features an analog RCA auxiliary input.

Audio control and display

With bi-zone audio capabilities, the Clarion CMM-20 allows independent control of two main audio zones. The user interface is designed for marine navigation, featuring a large rotary knob, backlit buttons, and a 2.37-inch (60 mm) high-contrast TFT LCD screen with adjustable brightness for optimal visibility. Audio settings include bass, treble, balance, and fader control (Zone 1 / Zone 2 or Subwoofer), as well as four equalizer presets (Off, Flat, Pop, Classic, Rock).

Marine design and integration

This source unit is built to withstand marine environments, with an IP66 rating against dust and water spray. Its design exceeds industry standards for salt fog resistance (ASTM B117), UV exposure (ASTM D4329), and vibration. The CMM-20 can be complemented by up to three optional wired remotes (sold separately), with a maximum cumulative cable length of 23 meters, allowing control from multiple locations.

Expert opinion

« Technical analysis: Clarion CMM-20 marine stereo source »

The Clarion CMM-20 marine stereo source represents a robust and versatile audio solution for vessels requiring a reliable entertainment system. Its dual-zone architecture is a strategic asset, allowing control of distinct sound environments, for example, in the cockpit and a cabin, or dedicating an output to a subwoofer without compromising the balance of the main speakers. This flexibility is valuable for vessels where space and functionality optimization are critical.

The integration of multiple audio sources, including Bluetooth 5.0 and USB with charging, simplifies connections for modern devices. Its compatibility with optional wired remote controls is a key selection criterion for custom installations, providing remote control points without the latency or interference sometimes associated with wireless solutions. Installation is relatively standard for a head unit of this type, requiring precise cutting for flush mounting and attention to power and speaker connections, but the pre-out RCA and AUX input wiring remains straightforward.

Its design, compliant with ASTM standards for salt fog and UV resistance, along with IP66 protection, ensures operational durability in the most demanding marine environments. It is a relevant choice for those seeking a reliable source unit with essential features, without a touchscreen or advanced network integrations, focusing on audio performance and resistance to the elements.
