On another matter. In post 1249 you posted a picture of the Wave io
connection. I have connected over the uf-l connectors but I'm getting blinks
from the dsp-overload led. I haven't listened to it yet but I suspect that it will
behave as it did for a few others. Did you try the uf.l connection ? And do you
think that you can find the time to make drawing of the connection. The
picture was a bit unclear.
Connections are detailed in the Startup Guide. The only addition is the power supply to the transmitter part of the WaveIO's IL715. That's just a wire from the 5VD on Expansion Port 1 to the I2S header of the WaveIO (plus the ground return).

Let's se now, first spdif is for channel one and two. Second spdif is for channel
three and four and so on, rigth ? I can't see any possibility to divide six
channels evenly over these outputs. Am I doing this wrong or...? I will try to
put the midfrequencis on one core since it has most done to it and see what
that gives.

Edit: That worked like a charm :-) 88% on core0 81% on core1.
Basically just moved channel one and two to channel seven and eigth.

This is going great just added a second eq to the subchannels (maybe will
go for a dipolesystem in the future) and that evend it out to 88/86 %

Hi ,

I would like to know if it is possible to have 8 I2S output, Is it software limited or hardware limited???

Thank you

Hi Everyone,

as my current Najda board is currently dismounted, I can't check this right now. could someone confirm the following hardware implementation on the board:

Lower cinch row : Left In/OUT1/OUT3/OUT5/OUT7
upper cinch row : Right In/OUT2/OUT4/OUT6/OUT8

Thanks in advance
Jean Claude

Not sure why you need the board at all to check this but according to the manual page 14 it is the other way round i.e.:

Upper cinch row : Left In/OUT1/OUT3/OUT5/OUT7
Lower cinch row : Right In/OUT2/OUT4/OUT6/OUT8

Currently only 6 I2S outs are supported.
It would be possible to increase this number by using some pins of Expansion Port 1. Indeed, the DSP has pin switching capability, i.e. you can reroute pins between I2S ports. I'd need to double check this however.
