Chambord Audio - BF-500 Filters V2

Looks great. What do the 6db and bump buttons do?

Cool features! Thanks.

What happens when you change the hpf to a lower frequency?

Our fist batch of BF-500 V2 is almost sold out!

Hurry if you want to grab one at the pre-order price

If I have units in stock, absolutely 😉

OK here is why you want an analog filter, to maximize your useable gain. If you have let’s say a major HVAC noise problem around 30HZ, if you go through the AD before filtering the level of that HVAC noise is going to determine your gain structure and headroom and resolution. You will never get it back, you can get rid of the noise but you can’t get that headroom back. Now at the very least let’s say you are in the same situation with analog filters. Let’s say that HVAC is roughly 100 dB of your single if I set a 12dB per octave filter with the -3 dB freq at 60HZ I’m going to knock it down 9 dB, set it at 120, 18 dB below the corner 240 - 30 below the corner. 18 dB per octave the 30HZ noise is going to be -15 below a 60HZ corner, 33, below a 120 HZ corner and 41 below a 240 HZ corner. A 24 dB per octave filter ( Linkwitz Riley ) is going to put that HVAC -21, dB below the corner, filter at 45 dB below the corner at 120hz, and 69 dB below the corner.
In a typical home environment you will notice the increased head room. On drums the kick is no longer eating up the headroom of every other open mics track.
