Clarion CMM-30BB Marine Stereo Source

The Clarion CMM-30BB is a marine audio unit of the "hideaway" or "black box" type. This means it is designed to be installed discreetly, hidden from view, and has no screen or direct control buttons on the main unit. It is specifically intended to be controlled remotely via a compatible NMEA 2000® multifunction display (MFD) or wired remote controls.

The CMM-30BB marine stereo source is designed to be remotely controlled. You can manage it via:

A multifunction display (MFD) compatible with NMEA 2000®. Wired remotes compatible with Clarion. The main unit has no direct user interface (screen or buttons).

For optimal installation, it is recommended to mount the CMM-30BB in a dry and well-ventilated location. If a dry environment is not available, a location not exposed to heavy spray may be used. It is also important to ensure the location does not interfere with factory-installed systems.

The CMM-30BB offers several audio connectivity options:

AUX inputs: Two auxiliary inputs (left and right) for connecting external audio devices. USB port: One USB 2.1A port for media playback and device connection (compatible with iPhone SE and later models). Bluetooth: Wireless connectivity for audio streaming from compatible devices. SiriusXM: Compatibility with SiriusXM satellite radio (requires a separate SiriusXM tuner and subscription). AM/FM radio: Built-in tuner for radio reception.

The Clarion CMM-30BB supports four independent audio zones. Each zone has pre-amplified outputs (L/R), and zones 1 and 2 also feature direct speaker outputs. This allows separate control of volume and audio settings across different areas of your boat.

The CMM-30BB is designed for use with 12V negative-ground vehicle electrical systems. The supply voltage must be between 10 and 16V DC. A 15A fuse is required on the +12V DC power wire for circuit protection.

Yes, the CMM-30BB is compatible with Apple devices. You can connect an iPhone (iPhone SE and later models) via the 2.1A USB port for media playback. Additionally, Bluetooth connectivity allows wireless audio streaming from any iPhone or compatible device.

The CMM-30BB offers advanced audio settings for full sound customization:

Treble, midrange, and bass control: Adjustment from -10 to +10 for each band.Balance: Left-to-right audio balance adjustment (-10 to +10).Equalizer (EQ): A 5-band equalizer with -10 to +10 control per band, which must be disabled to use the Treble, Mid, and Bass controls separately.

Yes, it is possible to rename individual audio zones for better organization. The CMM-30BB offers a predefined list of names to choose from, such as Bow, Bridge, Cabin, Cockpit, Galley, Helm, Stateroom 1, Stateroom 2, Tower, and Transom.

The mounting dimensions of the CMM-30BB main unit are 94 mm (3.68 in) wide by 79 mm (3.09 in) high. These dimensions are critical when planning the installation location for the "hideaway" unit.

To use the SiriusXM satellite radio with the CMM-30BB, you must have a SiriusXM Connect tuner and a SiriusXM subscription. Once the tuner is installed and connected, power on the CMM-30BB and select the SiriusXM mode. You should be able to hear the SiriusXM preview channel on channel 1. Subscription activation typically takes 10 to 15 minutes but can take up to an hour, during which the radio must remain powered on and receive the SiriusXM signal.

No, the CMM-30BB is specifically designed and certified for use only in vehicles equipped with 12-volt negative-ground electrical systems. Use with other types of electrical systems is not approved and may damage the device.

The CMM-30BB's USB port provides several playback features:

Shuffle playback of all tracks.Repeat playback of the current track or all tracks.Play all tracks in all folders.Display a list of available folders and tracks.

The CMM-30BB allows flexible management of paired Bluetooth devices. You can:

Connect already paired devices. Initiate a new pairing mode to connect a new device (this will disconnect currently connected devices). Assign priority to a paired device for automatic connection. Remove paired devices individually or clear all paired devices from memory.

Installation of the CMM-30BB requires appropriate tools and safety equipment. To ensure correct and secure installation, professional installation is strongly recommended. This helps prevent damage to the device or the boat's electrical system.

The sensitivity of the auxiliary input (AUX) on the CMM-30BB can be configured. You have two levels to choose from: 2V RMS or 1V RMS. The default setting is 1V RMS. This option allows you to match the input audio level to the connected source for optimal sound quality.

For each audio zone, the CMM-30BB offers multiple level control modes:

Variable: The zone volume can be freely adjusted.Absolute: The volume is fixed or follows a predefined level.Sub: This mode is available only for Zone 4 and is optimized for a subwoofer.Off: The zone is disabled.

Yes, the CMM-30BB integrates a parental control function for SiriusXM satellite radio. When this function is enabled, SiriusXM channels containing mature content are restricted and require entering a 4-digit lock code to access them.

The "Tuner Region" function allows you to configure the AM/FM tuner range and scale of your CMM-30BB based on your current geographic region. This ensures accurate and optimal radio reception by adapting the device to local broadcast standards.

The CMM-30BB is designed to be water-resistant, making it suitable for marine environments. However, it must not be submerged underwater or exposed to high-pressure water jets. It is built to withstand typical nautical use, including splashes and humidity.
