When a car is premium class, buyers naturally expect the sound system to be similarly high-end – but this is often not the case. Step forward Audison’s AF M12.14 bit, a compact, premium-grade all-in-one unit, which incorporates advanced Analog Devices’ ADAU1467 DSP with de-EQ, de-Time and de-Phase processing to ‘clean’ the signal coming from the car’s audio system. The sound is then calibrated to the original or aftermarket speakers and amplified by a 12x60W, fully bridgeable, high-efficiency Class D amplifier with dual power supply. The core DSP is controlled by Audison’s powerful, next-generation bit Drive software platform. Overall, the AF M12.14 bit is a brilliantly engineered, and highly impressive, sound system upgrade.
