This extremely versatile plug and play amplifier will set your speakers free from the constraints of vehicle manufacturers sound curves. 8-channels and Bit technology in a very compact case.

Following a lengthy and comprehensive development programme, the Audison AP8.9 Bit amplifier offers fabulous sound enhancement for multi-speaker amplified factory car audio systems. Research revealed that many car speakers are not driven with enough power to offer the control required for a car speaker system. Furthermore, distortion rapidly increases to unpleasant levels when the volume is turned up. The clean signal handling of the eight class D channels and the incredible signal processing power overcomes many of the stock issues.

Special Features:

Full DA - Full Digital Audio

Pure digital signal transfer with a resolution up to 24 bit / 48 kHz.

BIT DRIVE

Auto tuning by Audison bit Tune and communication with bit Drive portal.

DE-EQ - De Equalization

De-equalization function to “flatten” any equalization applied by default by OEM sources.

USS technology

USS technology allows AP 8.9 bit to work with head-units featuring the “speaker load detection” circuit
