The MA-12000i from Crown Audio is a professional stereo power amplifier designed for installed applications. The rugged chassis houses patented Class-I circuitry, which provides high-quality audio and gets the most power out of the amplifier with minimal wasted energy. The amplifier has built-in load, line voltage, and I/O monitoring, to protect against faults and shorts. If one channel experiences a failure, the entire amplifier will shut down, potentially saving your equipment.

The MA-12000i can operate in stereo or bridged modes, and offers XLR input and link/out connectors, as well as Speakon and Binding Post outputs, allowing you to connect to virtually any sound system. An Ethernet port lets you connect the amplifier to a network, allowing you to monitor and control the amp from any location. A global power supply and 5 different power cords make sure you’re connected, regardless of where you’re working.

The front panel features individual gain controls for each channel with lighted level indicators. LED lights show the status of Power, Ready, and Signal, and also indicate when you’re in bridge mode or connected to a network. Variable-speed fans with front-to-back airflow keep internal components cool for rock-solid reliability.
