The SPK-4P is a PoE+ full range loudspeaker combining network audio streaming (AVB), class D amplification and Digital Signal Processor (DSP). A single CAT5/6 network cable provides power, low latency audio and control for a true Plug&Play experience. The system consists of three key element:

  • First is the Audio Video Bridging (AVB) technology powered by a 500MHz XMOS processor which provides low latency, uncompressed and tightly synchronized streams to each speaker over standard networks.
  • An on-board 400 MHz Analog Devices SHARC processor also enables substantial signal processing for true high-resolution audio capability and equalization, crossover, and room correction capabilities. All to be accessed and programmed with miniDSP’s easy-to-use interface software.
  • Finally, a novel Multi-Level switching audio amplifier technology developed by Merus Audio provides 2x15W for powering 2 speakers (local + height). Each SPK-4P effectively being an amplifier for 2 speaker (Master + slave)

Features 

  • 3.5" Full Range driver
  • Stereo Class D Amplifier (2x15Wrms)
  • PoE+ powered or External Power supply
  • Onboard Sharc DSP processor for FIR/IIR control
