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

All d&b amplifiers incorporate sophisticated Digital Signal Processing capabilities for comprehensive loudspeaker management, switchable filter functions, remote capabilities and user-definable controls. They are designed specifically to power d&b loudspeakers and are the beating heart of all d&b systems. This tutorial will guide you through the basic functions of the D90 and D40, which represent d&b's next generation of high power four channel system amplifiers. D90 and D40 provide two user-definable 16-band equalizers with parametric, notch, shelving and asymmetric filters and up to 10 seconds of delay, all of which can be applied to each of the amplifiers’ four channels. As is the case for all other d&b amplifiers, they feature analog, MILAN and AES / EBU digital inputs assignable to each channel, not to mention System check, Input and Load monitoring, overvoltage protection, temperature and signal controlled cooling and switch mode power supplies.
