Description of Rebec RS4.1D
Rebec RS4.1D – 4.1-channel DSP power amplifier with a dedicated subwoofer channel
The Rebec RS4.1D combines four powerful speaker channels with a separate subwoofer channel in a single Class D power amplifier. The result is a flexible solution for those who want to drive both speakers and a subwoofer with built-in DSP and extensive sound adjustment options.
Four speaker channels and a powerful subwoofer channel
The four main channels deliver 100 W RMS per channel at 4 ohms, while the dedicated subwoofer channel delivers 250 W RMS at 4 ohms and up to 600 W RMS at 1 ohm. This makes it possible to build a complete system without a separate monoblock amplifier. The main channels can also be bridged in pairs for higher power output.
DSP for a Finely Tuned Sound System
The built-in DSP offers a 31-band EQ, Butterworth, Linkwitz, and Bessel crossover filters, as well as six savable sound presets. Adjustments are made via a computer or app. In addition to the five amplified channels, there are eight low-level outputs for expanding the system with external power amplifiers.
Flexible Connections
The RS4.1D features both high- and low-level inputs for connecting to various audio sources, including the car’s factory system. For digital audio sources, it offers optical and coaxial inputs supporting up to 192 kHz/24-bit, a USB audio input, and Bluetooth 5.4.
With powerful amplification, integrated signal processing, and numerous connection options, the Rebec RS4.1D is suitable both as the centerpiece of a complete car audio system and as the foundation for a more advanced DSP setup.
