Features of the Sinbosen DM-Series Amplifier board

The SINBOSEN DM series of active power amplifier boards offers a variety of models to meet the power requirements of different scenarios. Ranging from DM9.5 to DM30, the output power spans from 900W + 500W to 3000W, capable of driving speakers with different impedances, from 8Ω to 4Ω. Whether it is for small stage performances, medium-sized conference venues, or large outdoor events, the DM series can provide stable and powerful audio output.

Moreover, the DM series is equipped with a high-performance 48K DSP processor with FIR functionality. This means that users can make precise adjustments to the audio signal through the DSP software, including equalizer settings, delay adjustments, and volume control. The built-in DSP design not only enhances the flexibility of the system but also reduces the need for external devices, lowering the complexity and cost of the system.

For ease of operation, the DM series features an LED screen that can display real-time volume and temperature information. Users can easily adjust the volume and monitor the device's status through an intuitive interface.

In the case of high-power output, heat dissipation and protection mechanisms are crucial for ensuring stable device operation. The DM series employs a low-noise, variable-speed fan design with airflow from front to back, effectively reducing the temperature during operation. This heat dissipation design not only improves the reliability of the device but also minimizes fan noise interference with the audio signal.

The DM series also includes multiple protection mechanisms, such as temperature protection, short-circuit protection, and DC protection. These protective functions can effectively prevent device damage under abnormal conditions, extend the device's service life, and ensure the stable operation of the audio system.

Furthermore, the DM series' output circuit design utilizes SMPS + CLASS D technology, which not only improves the device's efficiency but also further reduces its size and weight. The fully sealed design and built-in shielding box allow speakers to be installed without the need for a partition, simplifying the installation process and enhancing system integration.
