The d&b audiotechnik D6 is a 2 x 600W power amplifier with built-in EQ and delay, active power factor correction, and system check, optimized for d&b loudspeakers.
If you’re spec’ing out a d&b system with medium to low power (2 x 600W peak), it follows that you’re going to need amplification that’s not only reliable and energy efficient, but specifically optimized for the superior response of d&b audiotechnik passive speakers. The d&b audiotechnik D6 is just such an amplifier. The 2U two channel lightweight D6 amplifier delivers medium power into low-impedance loads between 4 and 16 ohms and is ideally suited for use in both mobile and installation environments.
The D6 incorporates highly efficient Class D amplifiers that use a switch-mode power supply with active Power Factor Correction (PFC)*, suitable for mains voltages 100V/120V/200V/230V at 50–60Hz and maintains a stable and increased output when used with weak or unstable mains supplies. It comes with two NL4 loudspeaker output connectors. RJ 45 connectors enable access to the remote network via CAN-Bus. d&b System Check verifies that the system performs within predefined parameters, while d&b Load Monitoring enables automatic and continuous impedance monitoring. Both can determine the status of an LF or HF driver in systems with multiple elements, even if they’re crossed over passively.
The D6 has configurations for d&b loudspeakers and a linear mode. Exceptions are 2-Way Active, V-Series and B2-SUB. The signal delay capability enables user-definable settings of up to 340ms (=100m/328.1ft) to be applied independently to each channel. The same applies to the 4-band parametric equalizer, providing optional boost/cut or notch filtering. To configure the amplifier, the D6 features a rotary encoder and a LCD display
*What is power factor correction (PFC)—Power factor correction is a technique of increasing the power factor of a power supply. Switching power supplies without power factor correction draw current in short, high-magnitude pulses, which can be smoothed out by using active or passive techniques. This reduces the input RMS current and apparent input power, thereby increasing the power factor. Power factor correction tries to push the power factor of the power supply towards 1. It gets to as close as 0.95 which is acceptable for most applications.
