D12 amplifier
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. It utilizes an autosensing switch mode
power supply for mains voltages 115 / 230 V, 50 – 60 Hz (optional 100 / 200 V) and has a temperature and
signal controlled fan to cool the internal assemblies. It is specifically designed to produce high power
into low impedance loads, typically those between 4 and 16 ohms. A user definable 4-band parametric
equalizer, and signal delay capability of up to 340 ms are incorporated and can be applied independently
to each channel. A signal generator offering pink noise or sine wave program is also included. 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. All these functions and parameters can be easily accessed and
controlled via the LCD in conjunction with the digital rotary encoder or through the d&b Remote network.
