The D12 amplifier is a two channel power amplifier incorporating digital signal processors (DSP) to provide speaker specific set ups that include comprehensive protection functions for all current d&b loudspeakers. The D12 has both digital and analog signal inputs, loudspeaker outputs, remote control and monitoring abilities and interfaces, a sine wave and pink noise signal generator and controls and status indicators.

A user definable 4-band parametric equalizer, and signal delay capability of up to 340 ms are incorporated, these can be applied independently to each channel. The D12 also includes d&b SenseDrive for accurate control of the driver membranes in d&b subwoofers, resulting in an extremely precise low frequency performance. d&b load monitoring can provide both LF and HF driver status information within systems containing multiple drivers, even if these drivers are passively crossed over. All of these functions and parameters can be easily accessed and controlled via the LCD in conjunction with the digital rotary encoder. The D12 has a switch mode power supply enabling use without any adjustments for the supply voltage.
