DAA-2371 B – Digital Audio Power Amplifier 1 x 300 Watts

The PADES® 2000 Digital Audio Matrix Single Power Amplifier DAA-2371 B is a professional fully supervised Class D 100V single power amplifier. The switching power supply integrated in each output stage block contributes to the additional optimization of efficiency. Its speaker output is designed using transformerless technology. The amplifier has protection circuits against overheating and self-excitation, a line inrush current limit and inrush noise suppression; it is short-circuit-proof and idling-proof. All monitoring and protection functions are indicated via LEDs on the front display.

The rear is fitted with RJ45 and Phoenix connectors. The DAA-2371 B has integrated slots for the digital amplifier control module, 1 NF input transformer. The technology is extremely energy-saving due to its high efficiency and is characterized by low heating of the components. By using the digital emergency power input module, the DAA-2371 B can be operated with 24V emergency power. The Digital-Audio-Amplifier-Control-Module enables control and monitoring of the amplifier.

The digital selection of all input channels is done with 2 function keys and a rotary encoder tactile function. For the power amplifier channel, the operating states and the input signal are displayed via the front panel LEDs.

The integrated, automatically activated device sleep mode enables energy consumption optimization. Operating state automatically reactivates within 50 µs after detection of user-relevant events.

As is standard with professional audio equipment, the AF signal is connected via balanced inputs and outputs. In order to eliminate ground loops and other background noise, AF input transformers can be installed in the active signal paths to generate transformer-symmetrical, i.e. galvanically isolated signal transmission.

The HF shielding module protects the electronic components with system-grounded ones shielding effectively against high-frequency electromagnetic radiation.

For warranty reasons, all options can only be installed in the factory. All system components are delivered exclusively project-related. A purchase of individual components is unfortunately excluded.
