Audison Prima AP4.9 bit 4 Channel Amplifier Amp & 9 Channel DSP 520w RMS

AP4.9 bit

AP4.9 bit amplifier is ideal to realize a powerful two way front full active.

The built-in processor, that this amplifier shares with the AP8.9 bit, provides the ability to assign the pre-outs to the AP1 D amplifier, creating a very powerful system in a small space thanks to the “rack mounting” system.

Product Information

Full DA - Full Digital Audio

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


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.

DCC - Direct Current Cockpit

To speed-up installation time preserving safety and reliability, the Audison R&D team equipped the AP bit amplifiers with DCC, an innovative management circuit which monitors the power supply current consumption in real-time. This solution provides the ability to connect the amplifier to the cockpit directly without reaching the battery.
