Networked Amplification
Enabling audio amplification for networked audio systems, these products are designed to integrate Power over Ethernet and Networked Audio Processors to support multichannel speaker level outputs and line level outputs.
AMP-140C4
This is a digital amplifier board controlled by a Networked Audio Processor 1 (NAP1). And supports both wired and wireless audio streaming. V3 now includes built-in Wi-Fi 5, supporting the new streaming capabilities of NAP1: AirPlay 2 and Spotify Connect.
