You might have tried AC coupling. But I am also very partial to the IVY-III

Thanks Russ,

I was going to upgrade the caps on the previous Legato I was using....but by the time you buy some really good caps I could just buy the Legato III. I called the folks at Ayre and they corroborated that it doesn't really matter as they have a fully balanced design. You just cant always tell based on the literature from the manufacturers.

BTW I did really notice a improvement switching to the DC coupled version. The amp is also DC coupled as well. Sounds pretty good for no caps and no global feedback...

Looks like the first stab at the PRO I/V will be op-amp based. Are you guys going to have a few options in the future ala IVY and Legato? I know you cant make any promises...just asking.

Thanks again for all the work you guys do. Its great to feel like you have some skin in the game by assembling the parts/system. Having the option to upgrade over time part by part is fun as well.

Quick question to which I don't recall ever reading the answer:

Would it be possible to achieve good B3se performance in synch mode with the I2S transported via Teleporters? Asynch performance is very good, of course. Could one expect the same performance as synch mode without Teleporters? I also wonder if the master clock from Cronus version 1 would be robust enough to supply 3 teleporters. It would be a hassle at this stage to learn by experimenting...

TIA,

Frank

Default B3SE micro controller

HI,

bring for the first time to use an arduino (due) to control the B3se.

Did not figure hit hoW to connect to the IP_S header.

If I short the Pins with jumper I2S input is playing fine. Also if taking jumper away Spdif is playing fine.

Setting my SELECT2SPIN low and connecting it to the left pin ( underneath the IP mark) Spdif is playing. But If set the SELECTI2SPIN high (3.3 V) and connect it to the same pin nothing happens and Spdif input is still playing instead of I2S input.

How would I have to connect a micro controller to the IP_S select header?

Thx

Branko

Connecting sources for a dual mono configuration:

For spdif from what I read it is ok to parallel the connection to both boards. Is this correct?

I can't find a clear example of how the I2S is connected. I understand that the length must be short and it's best to use ufl cable. What is the best method?

Are the DAC and controller sharing a ground?

For both S/PDIF and I2S, just run them in parallel. Do not daisy chain the connections, however. Make individual runs from the source to each DAC.

More boards should be arriving any day, so I just opened up pre-orders, shipping end of next week. That *should* give me enough time to build
