As it is now I have Pulsar 2 & Power Sampler so I can get 16 ADAT via Pulsar 2 with little complication and another 16 via A16 on Z-Link, again with little complication and please bear in mind my PC has limited PCI slots so putting expansion plates in for the Power Sampler isn't too practical but adding more DSP and ADAT would be more sensible IMO...what do you folks think?
an a16u has, as mentioned, z-link ports as well as adat. those two ways of connection work simultaneously. you can feed the analog signal coming in via trs to both zlink and adat, that is: analog channel 1 will be routed to zlink port 1 and adat port 1 and so on.
(there is another mode you can set the unit to)
connecting the very same a 16u to both adat and zlink will give you the same signal on the corresponding inputs of your cards.
if you want to have 16 channels connected via zlink to your luna
and another 16 channels connected to you p2, you have to get yourself two a16u.
the luna adat expasion would give you, btw, another 16 channels of adat, which you could hook up a third a16u to
.
the adat expansion does not need a pci slot, but in most pc cases the slot cover will block a real pci slot, even though not needed. if you have a micro atx board in an atx case with free slot space available below the board (or beside), or a board with pci-e with unused pci-e slots you probably don't need to waste a real pci slot.
-greetings, markus-
ps. the adat ports on the luna don't do adat s/mux, while those of a p2 do, leaving you half the channels.
pps. if you'd get an zlink i/o plate for your p2 or even a new scope project with zlink you would be able to:
- connect an a16u via zlink (it has wo zlink ports)
- connect 8 channels via adat (the fostex has 8 channels, afair, so that would fit)
- upgrade your dsp capacity as well (if you get the whole card)
...apart from the people that have the vision of the bigger picture...
