>>The Lake FIR 3-way module has specific sample rate requirements for the output channels. It sounds like you might be using the same sample rate for LF and HF. The allowed combinations are 48|24|12 kHz or any combination of 24 and 12 kHz.
Yes, the different channels had all the same sample rate of 48Khz. I will check it out with different sample rates. What is the best distribution for the sample rates? Lower sample rate for the low channels and higher sample rate for the HF cannels?
>>I think you are referring to the Lake XP 1, 2, 3 and 4 way modules in Lake Controller 7.0. I’m surprised FIR Creator EX could load something into these. Whilst the internal Lake API might pass some data, we don’t actually support the XP modules from FIR Creator EX and FIR Designer; only from FIR Designer M. The modules are far more complex than the Lake FIR 3-way module and their multi-channel capabilities are more easily handled by FIR Designer M.
What obviously means that I’II has to update to the very expensive FIR Designer M to be able to work with the XP1, XP2,… Lake modules.
