Hello friends of fb2,

I am new to the FB & would like to re-adjust the bottom freq, especially for live use on big PAs.
I opened the fb2 & found both trimholes, but now I asking myself in which direction to turn & how much degrees to turn.
Finally how to test & find out the exact new bottom freq.
Maybe sb. got a suggestion for a "memory notation sheet" settings how to test the bottom freq. best?

Yes, I could just experiment, but that's a lot of money to risk for me.

greetings
df

PS: Dear admin, If I type wrong captcha I have to wait 60 minutes to finally try again & post?! That really sucks.

Hi Df

sorry for the delay, anyone with urgent questions, please mail me directly.

Adjusting the bottom frequencies won't help protecting the following gear for very low frequencies,
because ADSR and LFO amount can easily overrule those freq settings both in up and down directions.

If adjusting them, it is done best in high reso by ear, neutral LFO and ADSR amount.
Adjust of F2 is more sensitive then F1, this is normal.
If the (unavoidable) clock leaking sounds around 1 Khz, the freq will be 10 Hz, as it is factor 100 related.

I advice to use the low cut on the mix desk input channel,
or place some kind of low roll off filter/eq behind the FB.

Hope this answers your question
