That is roughly equivalent to 80 channels at 48k.  Are you sure the
hardware you have can handle that much real time data processing?

At 1M samples/second even 2048 is only 2ms.  You will need to do pretty
careful system tuning to guarantee 2ms response time without any missed
deadlines.  Do you really need 2ms latency is this system?  That seems
much lower than what most people seem to have success achieving on a
general music recording system, even with a -RT kernel.
