German audio technology and solutions company d&b audiotechnik announces the introduction of the new D40 mobile amplifier. The four-channel Class D amplifier features reduced size and weight, new voltage management features, and increased system performance while significantly reducing power consumption for improved environmental friendliness.

This newest addition to the d&b family is tailor made for mobile applications and represents a significant progression in amplification and comes as a result of research and innovation in the entire d&b ecosystem of technology.

“The D40 is a great example of d&b’s drive to produce innovative, high-performing audio solutions,” commented d&b Product Manager, Wolfgang Schulz. “Enhanced feature benefits and power efficiency combined with energy savings features increases system efficiency.”

The D40 is the mobile version of the 40D installation amplifier.

The amplifier’s user interface consists of a 4.3-inch (480 x 272 pix.) colour touchscreen and a digital rotary encoder, providing comprehensive information of the device configuration and enhanced status monitoring.

Dynamic Performance

The D40 amplifier has a dynamic range of 116 dB (unweighted) and is designed to drive high-voltage d&b loudspeakers while providing comprehensive management and protection capabilities. The D40 reaches 180V peak, delivering full performance from d&b KSL System loudspeakers and V-Series and Y-Series.

Flexible Processing Power

The D40 uses Digital Signal Processing (DSP) to incorporate loudspeaker configurations and user-definable setups, equalisation and delay functions.

Smaller Environmental Footprint

The D40 combines advanced voltage management to drive systems that demand less input power as a whole. The D40 includes enhanced energy saving features, power efficiency and Automatic Wake up for environmentally responsible and sustainable Green Building requirements.

System Reality

As part of the d&b family, the D40 benefits from the full range of d&b technology software solutions including ArrayCalc, ArrayProcessing, NoizCalc and the R1 Remote control software. These elements all come together in the highly efficient d&b Workflow, maximising the performance, usability, and value of d&b systems.
