I am working on a system that can drive 40 or so channels based on a zynq 7020 processor.
The zedboard which is the dev kit i am working with costs 320 for academics and ~400 for commercial uses. This will then drive a series of dac boards that I am working on. They are likely to cost about 200 each for 8 channels (ESS). Cheaper dac boards could be invisiged, or even direct driving digital class D modulators. I am mainly working on the player-control hardware. Regards. On Thursday, May 23, 2013, Augustine Leudar wrote: > Hi Alexis, > yes the box would need DA converters if thats what you mean.
