D90, D40, D25 amplifiers tutorial. Channel setup | d&b audiotechnik

All d&b amplifiers feature sophisticated digital signal processing capabilities for comprehensive loudspeaker management, switchable filter functions, remote control options and user-definable controls. They have been specifically designed to operate d&b loudspeakers and are the heart of all d&b systems. This tutorial guides you through the basic functions of the D90, D40 and D25, the next generation of powerful four-channel system amplifiers from d&b, in several chapters. The D90, D40, and D25 offer two user-definable 16-band equalizers per loudspeaker channel with parametric, notch, shelving, and asymmetric filters, as well as up to 10 seconds of delay, all of which can be applied to any of the amplifier's four channels. All amplifiers support d&b ArrayProcessing technology for the respective line array loudspeakers and, in addition to MILAN as an input signal, feature analog and digital AES3 inputs that can be assigned to each channel. Other features include system check, input and load monitoring, overvoltage protection, temperature- and signal-controlled cooling, switching power supplies and much more.
