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

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
