Setting center frequency of each RTL-SDR for different frequencies

I just purchased the KerberosSDR and should get it soon.
My application I need to start all four SDRs at the same time at different frequencies.
Is this possible? I assume reading the 4 rtlsdrs going the the USB must be round robin?

If you don't need coherency in your application then yes it is possible to start them all at the same time (within a few ms).

But you won't be able to start them all exactly at the same time. There will be USB timing differences, this is why we correlate after with the noise source for coherent operation.
