Rebec RPX-B12S
The Rebec RPX-B12S is a high-performance integrated DSP amplifier from the RPX-B Series, combining a 12-channel digital signal processor with twelve channels of Class D amplification in a single chassis. Developed for advanced active car audio systems such as 3-way front plus 2-way rear active setups, it expands on the RPX-B1012 with more amplifier channels, significantly higher output power and an upgraded digital audio platform.
Key Features
- 12-Channel DSP Processor: Built around the Analog Devices ADAU1463 with PC tuning software for crossover, equalization, delay and routing
- 12-Channel Class D Amplifier: 100W RMS on every channel at 4 Ohm to power a complete active speaker system
- Bridge Capability: Up to 200W RMS x 6 bridged channels at 4 Ohm for speakers requiring more power
- Comprehensive Inputs: 12 high-level inputs (30Vpp), 2 low-level inputs (6Vpp), Optical and Coaxial up to 192 kHz, USB Audio 2.0
- External Bluetooth Support: Add wireless audio with an external Bluetooth module according to system requirements
- 12 RCA Outputs (2.35V): Flexible signal routing and future expansion with external amplifiers
- Dedicated Audio Hardware: AK4438 DAC and PCM1840 ADC for accurate conversion in the signal path
- 31-Band Equalizer: Detailed frequency response adjustment for any vehicle environment
