1. Works as a breakout board making the connections on the 36 pin board connector easily useable
2. It provide impedance adaptation, making it easier for sources to drive the Purifi 1ET400A module - you get more linear response, including better bass, for instance
3. It can be configured to provide additional gain- the Purifi module only has 12.8db of gain.
Thanks for the explanation. So from my reading through this thread, if I were to get the Neurochrome buffer boards, I should then probably get two individual 1ET400A modules instead of the EVAL1 kit, right?
The EVAL1 kit has connectors for the power supply and also has XLR inputs and speaker terminals (I plan on adding my own terminals either way). Is it safe to assume the Neurochrome buffer board would have connections for XLR inputs (by soldering wires somewhere)? And would power go directly from the SMPS1200 to the two individual 1ET400A modules, vs the add-on board that comes with the EVAL1? And where would speaker terminals connect to?
I plan on studying the diagrams on the Purifi site more closely, but I'm currently on my phone which isn't an ideal medium for studying such things
Edit: I just saw on the Neurochrome site that the speaker outputs are on the buffer board, so that answers that question. And it also has a power supply connection. But since this would be using two separate modules + input buffers, requiring each to be powered individually, does the SMPS1200 have two power outputs, or would I need to use a splitter of some sort?
