The d&b D12 amplifier is a dual channel amplifier incorporating digital signal processors (DSP) to provide loudspeaker specific configurations and functions. It is designed for use with all d&b loudspeakers, has both digital and analog signal inputs as well as link outputs, remote control and monitoring capabilities and sophisticated protection circuits.
The D12 uses its Load monitoring and System check functions to ascertain the status of the loudspeaker impedance. d&b System check verifies that the system performs within a predefined condition, whilst d&b Load monitoring enables an automatic and continuous impedance monitoring. Both can determine the status of an LF or HF driver in systems with multiple elements, even if these are crossed over passively. Apart from selectable output configurations for dual channel, mixed TOP/SUB and 2-Way Active mode, the D12 also provides d&b SenseDrive for use with the LF drivers in d&b active loudspeakers and subwoofers and has output connector options.
