d&b audiotechnik’s new D40 mobile amplifier boasts reduced size and weight, advanced voltage management and increased system performance, while significantly reducing power consumption for improved environmental friendliness. d&b product manager, Wolfgang Schulz answers Headliner’s burning questions on the mobile version of the manufacturer’s 40D installation amplifier.
What makes the D40 amplifier innovative?
WS: The D40 has been tailor-made for mobile applications and incorporates comprehensive loudspeaker management, switchable filtering functions and uses advanced Digital Signal Processing (DSP) to incorporate loudspeaker-specific configurations and user-definable setups, equalisation and delay.
The D40 represents a significant progression in mobile amplification, inheriting benefits from advances made in high efficiency loudspeaker design.
What are ideal mobile applications for the D40 amplifier?
WS: The unit's small 2RU size, reduced weight and connectivity flexibility makes it a perfect choice for mobile applications. The unit’s powerful signal processing extends the level of functionality of the onboard features.
These include a range of loudspeaker-specific filter functions plus two user-definable 16-band EQs, which facilitate system tuning. The delay capability covers a range of up to 10 seconds, designed to drive the d&b KSL medium to large format three-way line array loudspeakers to their full performance potential.
The d&b audiotechnik approach is to build integrated sound reinforcement systems that are more than the combination of parts. Every element is tightly specified, precisely aligned and carefully matched to achieve maximum efficiency.
All user-definable parameters are incorporated for ease of use, allowing adjustment – either directly – via remote control surfaces, or integrated within wider networks.
