Know before you buy
Yes, the MBT-CRXv3 features an IP67 rating, meaning it is fully protected against dust and can withstand immersion in water up to one meter deep for 30 minutes. It is specifically engineered to handle the moisture, salt spray, and vibration common in marine and motorsports environments.
The unit allows for independent level control over two main audio zones, and it includes a dedicated subwoofer output. This gives you the flexibility to balance your sound levels across different areas of your vessel or vehicle.
This is a standalone Bluetooth controller. It connects directly to your amplifiers via its 4-volt preamp outputs, eliminating the need for a traditional head unit or radio source.
The MBT-CRXv3 supports Qualcomm aptX HD audio, which allows for high-resolution wireless streaming. When paired with a compatible device, it delivers a significantly higher fidelity signal than standard Bluetooth, resulting in cleaner, more detailed audio.
The controller uses a standard gauge-hole mounting design, which is the same size as many common marine instruments. If you are replacing an existing gauge or have a flat surface, the single-hole design makes for a straightforward, clean installation.
Yes, it includes a dedicated +12-volt remote turn-on output. This allows the controller to automatically power your amplifiers on when the unit is active and off when it is not, saving you from needing a separate manual switch.
