The Procella DA03-DSP is the second Class-D amplifier which is Designed by Procella Audio (Manufactured in China). The DA03-DSP has massive output power and can drive every Procella loudspeaker and selected subwoofers.

Delivering a solid 280W per channel at 8 ohms and 25A current. This new Class-D amplifier will ensure a wide dynamic range with low-frequency impact and a transparent and musical sound quality that will satisfy the most critical listener.

This four-channel amplifier has 40 presets for all Procella loudspeakers and full-range speakers and selected subwoofers. The 2024 model has a new colour display and MCU controlled fans. New are 4 channels of AES3 digital inputs and large format Euroblock connectors for large diameter speaker wires. To complete the connectivity we added a 12 Volt remote On/Standy. For those who would like to switch the power amplifier On/Off we have an API document available in our download section.



The DA03-DSP is a high output power amplifier and has the horsepower to bring out every little detail of Procella’s high-output speakers and subwoofer models.

Procella’s DA03-DSP can be used as a four-channel amplifier to produce 4x 280W (8 ohms) and 4x 500W (4 ohms), but switch to bridge mode, and it will deliver 2x 1.050W (8 ohms).

In a single rack unit, this power station ensures maximum output and dynamic range, especially for Procella loudspeakers.

40 factory presets enable multiple configurations with Procella’s high output speakers and subwoofers.
