AP4.9 bit

4 channel amplifier featuring
9 channel built-in 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 - 2 ? total power
