So will the Mercury only work with the 2 channel version, or will it also work with the multi-channel version?

I understand this is probably a bit premature, but does this earlier image show the I/V stage that you refer to as "huge" and "expensive" and a harbinger of the 8-channel version to come?

Thanks!

No, that was a very early design idea - it is similar - and actually that one in the picture looks like it is for stereo use


Cheers!

You can use 4 mercury to get 8 channels - but I will have a better solution for that.

about 100ma per channel (each has it own supply input)

So combined ~ 200ma - I power mine with a single Placid HD-BP right now.

It's easy enough to connect that pad to ground via a jumper.

Thoughts? I know many of you would not be put off by such a small error - but some will - so I am open to the idea of open sales for 1.0 with the errata - everyone else will just need to wait a week or two for 1.1 boards to arrive (which will only be different in that one way)

LOL... that's an easy fix.

Hi Russ,

Could you give a preview of the multi-channel architecture?

Is it the DAC board mounted to a single analog board with 4x2 Channels of mercury IV?

Just to confirm, 100ma + & 100ma -, correct? AND at +-15V?

TIA!

Yes - both rails will be very near those values at +/- 15V per channel (so 200ma total per rail for both).
