Almost.

The RxEQ is applied to the *AF* filter, which also implements low pass, 
manuall noth, etc.  The SHIFT and WIDTH controls apply to both an IF and an AF 
filter.

Thus, the RxEQ is not an additional filter cascaded with other audio filters, 
but is part of the description of the desired filter being fed to the filter 
design routine in the DSP firmware running in the K3.
