The miniDSP SPK-4P is a PoE+ full-range speaker combining audio streaming (AVB), Class D amplification and digital signal processing (DSP). A single RJ45 Cat5/6 Ethernet cable is used to power the speaker, stream audio and control the device, for a true Plug&Play experience. The system consists of three key components:

• Audio Video Bridging (AVB) technology, powered by a 500MHz XMOS processor, ensures very low latency and offers an uncompressed and perfectly synchronized audio stream between each speaker on the network.
• An Analog Devices SHARC 400MHz processor is in charge of processing the signal and offers an equalization, filter and acoustic correction system. Each element is accessible and can be set via the intuitive software provided by miniDSP.
• A new multi-level switching audio amplifier technology developed by Merus Audio allows the SPK-4P to deliver 2x15W power. This means that each SPK-4P can act as an amplifier for two speakers (master + slave).
