Hi Folks, I came up with something yesterday that I’m hoping some of you might know the answer.

I’m running a PT HD Accel rig (1 core card, 2 DSP cards) PT V.10 with a bunch of inputs and outputs connected via (1) HD I/o, and (3) 192’s. The reason for so many channels is we’re doing livestreams with a 6 piece jazz group all playing at the same time live.

I know there is a channel limit for this setup, I’m just not sure what it is.

All inputs work until I reach the last 192 which has 16 inputs. Channels 1 and 2 work and then everything stops working from channels 3 through 16. When I say “stops working” what happens is I can see level at the interface but in PT no input level comes through.

With all of these interfaces I have 56 input channels. If you subtract 14 from that (the channels on the last 192 that aren’t working) you get 42 channels.

Is there a 42 input channel threshold for this rig?

To make sure nothing was wrong with the last 192 I connected it as the sole interface and everything worked as it should.

Many thanks folks and can’t wait to hear your thoughts….best, Peter
