Audison AP8.9 bit
AP8.9 bitDSP Amplifier | 520 W | 9 CH DSP + 8 x 65 W @ 2 ohm | D-class Fully Bridgeable
The AP8.9 bit amplifier was designed by Audison R&D Department to achieve maximum sound quality in OEM Integration applications. The powerful management software proves the ability to acquire the bit Drive presets which the Audison team fine-tuned specifically for your car. Thanks to the innovative power supply stage, a power of 520 W total can be achieved in an extremely compact case. The non-amplifiable ninth channel can be used to drive a subwoofer via the mono AP1 D amplifier.
