The filters are "optional", so there is no "normal." The most "typical" 
selection of filters to put in the 6.3 MHz IF filter slots are ones that 
correspond to the labels on the buttons. That would be 1.8 kHz, 500 Hz 
and 250 Hz bandwidths. 2.4 kHz is the standard filter supplied with the 
Omni VI.

In the case of the 9 MHz "N-1" and "N-2" slots, the choice of filters is 
very much dependent on the operators favorite modes of operation. An 
operator who is only interested in SSB might want to fill those two 
slots with 2.1 kHz and 1.8 kHz bandwidth filters. Someone who is focused 
on CW operation may want  500 Hz and and 250 Hz BW filters there. 
Ten-Tec also has (or had) a 500 Hz BW filter with a center frequency 
appropriate to produce lower audio notes on CW. An RTTY operator might 
want the 500 Hz filter, with the center frequency needed for higher 
audio tones.

(The specific center frequencies of the 9 MHz IF filters is only 
relevant to the Omni VI and other transceivers that have non-frequency 
agile BFOs. Many rigs these days have a PLL controlled BFO frequency 
that can be set to get any audio frequency note desired from whatever 
makes it through the IF filters. That capability makes it unnecessary to 
have more than one center frequency option for multiple filters of the 
same bandwidth.)

If you get your filters from suppliers other than Ten-Tec, such as 
Inrad, there are yet more options to choose from.
