Audison Prima Series AP4.9 bit 4-Channel Amplifier with Built-In Digital Sound Processor
AP4.9 bit amplifier was designed for the Integration into OEM front/rear systems where a lot of power is required. 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 to drive a subwoofer, to the AP4 D amplifier to have 4 additional amplified channels exceeding 1080 W @ 4 - 2Ω total power.
