The 2 RU 25D amplifier provides power output optimized for smaller installation systems, while offering the same full DSP feature set as our high-output amplifiers.
The 25D amplifier has a dynamic range of 112 dB (unweighted) and is designed to drive high voltage d&b loudspeakers while providing comprehensive management and protection capabilities.
The user interface consists of a 4.3" (480 x 272 pix.) colour touchscreen, which provides comprehensive information about device configuration and enhanced status monitoring.
The 25D also includes enhanced energy saving features, power efficiency and Automatic Wake up for environmentally responsible and sustainable Green Building requirements.
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.
This device contains extended input management functionalities with separate Input Gain control for each input channel, General Purpose Inputs/Outputs (GPIO) and a General Fault connector. Enhanced system status monitoring functions such as Input and Load monitoring ensure suitability in an emergency situation.
