ACV MARINE is a brand dedicated to marine electronics. High-quality waterproofing and reliability in any conditions!
The ACV MRD5.1200B waterproof digital 5-channel amplifier is an excellent choice for marine vessels, off-road vehicles, and cars where reliability and sound quality in high-humidity conditions are essential. The device is IPX6-rated, ensuring resistance to splashes and jets of water. Built-in Bluetooth 5.1 with automatic pairing allows for easy connection to any Bluetooth device, simplifying music control and enhancing user comfort. The compact heatsink with an efficient cooling system ensures reliable operation in tight spaces and under extended use. A multi-level protection system and the ability to drive a 2-ohm load ensure stability and safety when used at high power levels. A switchable input mode between 4- and 5-channel modes provides flexibility in customizing the sound system for different environments.
High-tech circuitry ensures pure sound with minimal distortion (THD 0.05%) and a wide frequency response—from 10 Hz to 30 kHz (4 channels) and up to 250 Hz (5 channel). Adjustable LPF/HPF/Subsonic filters allow precise sound tuning for various speaker systems. The amplifier boasts high input sensitivity, channel separation of over 66 dB, and a signal-to-noise ratio of over 105 dB, ensuring professional-grade sound quality. Its dimensions (381 x 135 x 48 mm) allow for easy integration into confined spaces in marine or automotive systems without sacrificing functionality. All this makes the MRD5.1200B a versatile solution for high-quality sound in extreme conditions such as sea voyages or car trips.
Allows you to use a mobile device (smartphone, tablet, etc.) via Bluetooth as an audio source to play music wirelessly. Bluetooth function simplifies connection and gives more comfort during operation.
Protection against splashes of water and rain. PCBA with conformal coating.
Stable operation at 4, 2, and 1 ohm loads and compact dimensions. The device stably drives loads of 4 and 2 ohms (channels 1-4) and 1 ohm (channel 5), making it ideal for powering high-output full-range speakers in your vehicle and a subwoofer. The device has compact dimensions of 381x135x48 mm.
The MRD5.1200B digital amplifier is much more powerful and compact than class AB. When operating such amplifiers, you can use less power and efficiency reaches 90%. With the digital amplifier, the speaker system will reveal its full potential.
Wide compatibility with various receivers.
Reliability throughout the entire service life.
