here's a pic of the new analogue board.

It has optical isolated power switching for preamp channels

Also has +/-5 and +-10v power monitoring with reference 3.3v using

resistor dividers.

It all looks bigger than it will be when its soldered together without

headers as connectors !

the power backplane on the right will probebly get smaller.

It will have 8 analogue differential channels in and 4 out.

2 high quality stereo headphone drivers

and timecode IO.

The ADC DAC board at the back will bridge over directly to the digital

board.
