Re: IRE Black level at 0 (zero)?

I was reading the Final Cut Pro Bible and I think that I am understanding this better (please correct me if I am wrong).

On the Kona control panel, of you select "7.5" as the black level, then it will not outout any black lower than 7.5 IRE.

If you select "0", then black levels from 0 to 7.5 will also be exported through the Kona onto the tape deck.

Do I understand this correctly?

If this is true, then when the festival was asking for a "zero IRE setting," then by selecting "0 IRE" on the Kona control panel, this is accomplishing this.

Please verify that this is correct so that I won't need to rent my BetaSP deck beyond the weekend :)

Thanks,
