Regarding the power distribution challenges of the PP4 post-amplifier, we provide the following detailed explanation. This amplifier supports both 4-channel and 2-channel output modes. In 4-independent-channel mode, each channel delivers 175W of power output. By employing bridge configuration to combine every two channels, the total output power can reach 250W. For users already equipped with 5.1-channel AV amplifiers, the PP4's functionality offers flexible customization. Through channel redirection, the bridged channels can serve as left and right rear channels to create richer audio effects.

Users may also opt to bridge a single channel to form a 3-channel amplifier, while redirecting the original AV amplifier's left/right channels to side surround channels for upgrading from 5.1 to 7.1-channel systems. Another configuration approach involves assigning the PP4's four channels to side surround and ceiling channels respectively, enabling immersive 7.1.2-channel audio systems. Although CAMMICA's product manual provides several recommended configurations, we believe users can explore diverse application scenarios and configuration options through practical implementation.
