d&b announces D40 controlller amplifier

German audio technology company d&b audiotechnik has announced the introduction of the D40 mobile amplifier, the mobile version of the 40D installation amplifier. The four-channel Class D amplifier features reduced size and weight, advanced voltage management, and increased system performance while reducing power consumption.

This newest addition to the d&b family is made for mobile applications and reportedly 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. Enhanced feature benefits and power efficiency combined with energy savings features increases system efficiency", says Wolfgang Schulz, Product Manager, d&b audiotechnik

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

The D40 amplifier has a dynamic range of 116 dB (unweighted) and reaches 180V (or 35 amps) peak, delivering full performance from d&b KSL System loudspeakers and V-Series and Y-Series (specifically, 4 x 2400/2000W into 4/8Ω). It uses Digital Signal Processing (DSP) to incorporate loudspeaker configurations and user-definable setups, equalization and delay functions. The units weighs 13,8 kg (30,4 lb).

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

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.
