So do I, so I hope the proposed changes will not affect the connections to BII.

I think Buffalo II and III have the same layout (mounting holes and boar-to-board connections) when used in stereo mode. At least they both fit the same twisted pear I/V stages. The BIII board is just a bit longer in the digital input end.

Owen, the shunts are not optional on BIII and there is no onboard power at all. the digital inputs and switching are completely different and actually IMO overcomplicated, I think they require the external receiver MUX unless you send it TTL which as you know the ESS will take natively, but then you would be occupying one of the i2s inputs and stop any i2s switching. I dont think you can really cater for it on the board TBH and would not look forward to the delay it would cause to try, it would be a complete redesign.

if you thought the ackodac was complicated, BIII takes it to another level IMO

[QUOTE=opc;3055500]
I need to ask a favour though... is there anyone out there with a BIII who can provide a diagram with the positions of the inputs and outputs? I'd like to re-arrange the PCB so that it works perfectly with the BIII as I don't think anyone can get the BII any more.

/QUOTE]

I have the BIII and can measure the dimensions, please give me a couple of days.

No I can't do it confidently from online info, there isn't enough detail that I can find.

ask Iancanada, hes bought it recently and is part of this GB, he has made some adapters for his fifo sync mode clock adapters, so is bound to have taken some good measurements and may even be able to share usable documents (minus unwanted or proprietary detail) from his layouts

please dont get rid of the ackodac mounting holes!! its actually started to pick up steam with more owners including about 4-5 of us (that I know of) in this thread, I suppose it would be asking too much to have a signal input to suit, but please dont lose the mounting holes

Hi Owen,

Hope the protest didn't interrupt the F1 too much...!

Since there's already a large BII base out there, including myself, I'm hoping you're planning on keeping the BII layout in there?

I'm not really wanting to change the BII since there's no real improvement in SQ/advantages going with BIII except for separate 8 output...

Thanks
Do
