N-DAC2
Stereo AVB DAC endpoint, PoE+ powered, Onboard Sharc DSP, Plug&Play on MAC OSx with AVB support Array

The NDAC-2 is an Audio Video Bridging (AVB) endpoint combining network audio streaming, DAC and Digital Signal Processor (DSP) in a pocket size box. 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:
- 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. Thanks to its compliance with IEEE 1722.1, it is plug&play with 3rd party AVB devices such as Apple OSx, Biamp Systems, Audioscience, Echo Audio…
- An on-board 400MHz 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 stereo DAC powered by ESS Technology ES9018K2M outputs balanced out on phoenix terminal blocks.
With its Power Over Ethernet (POE) capability or external +12VDC supply, the NDAC-2 is easily installed in a matter of minutes with limited knowledge.
