Stage Directions • Tools of the Trade • June 28, 2021

German audio technology and solutions company d&b audiotechnik today announced the introduction of the new D40 mobile amplifier. The four-channel Class D amplifier features reduced size and weight, advanced voltage management, 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 the mobile version of the 40D installation amplifier.

“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 amplifier’s user interface consists of a 4.3-inch (480 x 272 pix.) color 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, equalization, 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.
