D12 amplifier

The 3 RU two channel D12 amplifier delivers medium to high power into low impedance loads between 4 and 16 ohms and is ideally suited for use in both mobile and installation environments. The D12 contains setups for all d&b loudspeakers and a linear mode. The signal delay capability enables user definable settings of up to 340 msec (=100 m/328.1 ft) to be applied independently to each channel. The same applies to the 4-band parametric equalizer, providing optional boost/cut or notch filtering. The D12 incorporates a digital rotary encoder and a LCD display to configure the amplifier.

The D12 utilizes an autosensing switch mode power supply for mains voltages 120 V/230 V, 50 - 60 Hz (optional 100/200V). The D12 amplifier incorporates d&b SenseDrive for accurate control of LF drivers in d&b loudspeakers driven in 2-Way Active mode or in actively driven d&b subwoofers. When the D12 is fitted with EP5 connectors and appropriate 5 wire cabling, d&b SenseDrive can be used, resulting in an extremely precise bass performance even at high levels. NL4 and NL8 connector options are also available. RJ 45 connectors enable access to the Remote network via CAN-Bus. 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.

Architectural specifications

Architectural specifications

Architects' and engineers' specification
The amplifier shall be dual channel incorporating digital signal processors (DSP) to provide loudspeaker specific configurations and functions for d&b loudspeakers. It will be equipped with digital and analog signal inputs as well as link outputs, remote control and monitoring capabilities and sophisticated protection circuits.
It will have a temperature and signal controlled fan to cool the internal assemblies. A user definable 4-band parametric equalizer, and signal delay capability of up to 340 ms shall be incorporated for independent application to each channel.
It will contain a signal generator offering pink noise or sine wave program.
Load monitoring and System check functions will be included to ascertain the status of the loudspeaker impedance. Load monitoring shall be included to allow impedance monitoring to determine the status of an LF or HF driver in systems with multiple elements, even if these are crossed over passively.
Load and Input Monitoring shall be suitable for use in applications compliant to EN 60849/IEC 60849 ‘Sound Systems for Emergency Purposes’.
Output configurations shall be selectable for dual channel, mixed TOP/SUB and 2-Way Active modes.
d&b SenseDrive will be incorporated for use with subwoofers and the LF drivers in active loudspeakers compensating for the influence of cables and to improve impulse response.
