Fast data transmission
Unpacked and immediately noticed that the Quantum 2626 is heavy and very solidly built. Sockets and regulators are of very good quality, you can feel that immediately. The power adapter is also of good quality. However, one peculiarity should be mentioned, which may or may not be the fault of Windows. The Quantum 2626 is only initialised after Windows is restarted; and the Quantum 2626 must be switched on when restarting. If the Quantum is switched on while Windows is running, or switched off and on again, the LED lights up red, which means it is NOT communicating with the PC, or the PC is not communicating with it. If you leave the Quantum switched on, restart it with Windows 11, the Quantum and Windows 11 initialise and the LED lights up blue. Only then will it be recognised in the required Presonus software "Universal Control". I don't know if this is also the case with Mac OS, but some people have reported this peculiarity. But if you know, you can live with it. Once you have connected the Quantum2626 to the PC and the instruments, leave the Quantum switched on and restart the PC, then it will work. The latencies are really amazingly low, with 48 Khz and 128 sample rate at 2.8 ms, with the same sample rate but 96 Khz, a latency of just 1.3 ms. Whereas 48Khz is sufficient and does not load the CPU as much as 96 Khz. You have to try out the sample rate, with 64 samples the latency at 48 khz is just 0.9 ms, although with my CPU crackers are detectable, 128 sample rate is the better setting for me. You have to try it out, which sample rate is the best, no CPU is the same as the other, and other factors and components depend on it. If someone can manage with 32 sample rates, the latency is just 0.5 ms, a dream, but not necessary. The rule is, any latency under 12 ms is a usable and good latency, the less, of course, felt better.
