Scott,
Up to you,
I don't use the 500 Hz filter even though I have one and keep it for now, so
you could store the 1Khz filter in that position with the 500 Hz filter
disabled. The 250 Hz filter is usefull, the degradation at 250 Hz, is much
less.
The filters 500hz filter can also be used in the OMNI A/B/D series and also
in the OMNI V IV IV+ Opt series.
Best wishes,
Rich
