I looked at the site. Are you intending to use it for the full system? or just
the sub-woofers?
Looks like the configurations can be saved to the device. I assume on power up
they resume their configuration, but I could not tell for sure. There is the IR
remote to select a configuration.
I have tried programming an Analog Devices DSP in the past, a complicated beast
to program. The overall system here looks to manage it well, as far as I can
tell. Would be interested in hearing what you end up doing.
10Hz, 120db. Just get some "butt kickahs" like they use at Jordan's furniture
IMAX.
