- Mobile Amplifier (d&b)
Mobile specific four channel amplifier
The D90 amplifier represents a new performance level of four channel Class D amplifiers, purposely designed to meet vital requirements for touring and rental productions companies, where high flexibility with system design and production needs are imperative.
With key features such as maximum output voltage, digital signal processing capabilities, and the AutoStandby and AutoWakeup, the D90 amplifier reduces the overall power consumption of the system.
The D90 incorporates comprehensive loudspeaker management, switchable filter functions, and definable equalisation.
The D90 amplifier has a dynamic range of 119 dB (unweighted) and is designed to drive high voltage d&b loudspeakers while providing extensive protection capabilities.
The user interface of the amplifier consists of a 4.3" (480 x 272 px) colour touchscreen in conjunction with a digital rotary encoder providing device configuration and enhanced status monitoring information.
The D90 amplifier features a flexible Fallback structure, ensuring the transmission of a secondary signal when required.
Remote control and full system integration are realised using the d&b ArrayCalc simulation software and R1 Remote control software.
