Rebec A12S
The Rebec A12S is a Hi-End DSP amplifier from Rebec’s A Series, combining eight channels of Class AB amplification with an integrated digital signal processing platform. Its amplifier section is divided into two power groups – four channels with 80W RMS and four higher-power channels with 150W RMS at 4 Ohm – giving great flexibility for active car audio systems where different speaker sections need different power levels.
Key Features
- 8-Channel Class AB Amplification: 80W RMS x 4 (CH 1-4) plus 150W RMS x 4 (CH 5-8) at 4 Ohm; 100W x 4 plus 250W x 4 at 2 Ohm
- Bridge Mode: Channels 5-6 and 7-8 can be bridged for 450W RMS x 2 at 4 Ohm or 600W RMS x 1 at 2 Ohm
- Upgraded DSP Platform: ADAU1463 DSP chipset (48 kHz sampling), AK4438 DAC and PCM1840 ADC – a step up from the A8S
- Factory System Integration: 12-channel high-level input (30Vpp) and 2-channel low-level input (8Vpp)
- 192 kHz Digital Inputs: Coaxial and Optical (Toslink) inputs supporting signals up to 192 kHz
- System Expansion: 4 low-level outputs (2.35V) for connecting additional external amplifiers
- Bluetooth Ready: Supports an external Bluetooth module
- PC Tuning: Complete system configuration via PC software
