Crossovers are implemented as series biquad filters. There are two groups of 4 biquads per channel. Each group can be bypassed individually.
The command follows the same syntax as the
peq command, for the exception that you have to specify the group index (0 or 1) in addition to the peq index (0, 1, 2, 3)
