Creating a Very Powerful System
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.
