The d&b Audiotechnik D12 is a professional two-channel power amplifier engineered as the heart of the d&b system concept, delivering exceptional performance for both touring and fixed installation applications. Housed in a robust 3U rackmount chassis, this amplifier provides 1200 watts per channel into 4 ohms, making it ideally suited for driving the full range of d&b loudspeakers with authority and precision. The D12 integrates comprehensive digital signal processing with factory-stored setups for every current d&b loudspeaker, ensuring optimal system performance through specifically tailored controller functions.

Beyond its amplification capabilities, the D12 incorporates sophisticated technologies that enhance system control and reliability. The proprietary d&b SenseDrive technology enables precise control of LF drivers in two-way active mode or subwoofers, delivering extremely accurate bass performance even at high output levels when used with EP5 connectors and appropriate five-wire cabling. The amplifier features a four-band parametric equalizer per channel with boost/cut or notch filtering options, plus independent signal delay of up to 340 milliseconds for system alignment. An autosensing switch-mode power supply automatically adapts to mains voltages worldwide, while integrated load monitoring continuously checks impedance to verify driver status across multiple system elements. With both analog and AES3 digital inputs, CAN-Bus remote control via RJ45 connectors, and an intuitive front-panel LCD with digital rotary encoder, the D12 represents a complete, intelligent amplification solution that defines the modern standard for professional loudspeaker systems.
