BF-500 // Butterworth Filters in 500 Format
« on: February 26, 2018, 01:21:16 PM »
Hi Guys,

A few months ago a colleague ask me if I could build a simple LPF & HPF in 500 format. Here's the result  ;)

- Independent In/Out switch for both bands
- 6 dB/oct switch for both bands (12 dB/oct. default)
- Bump function on the HPF (à la Harrison) = 5 dB (modified to 3 dB) resonance around the cutoff frequency.
- LED indicator on every switch

Cheers

Heh! The album’s going well thanks, if very slowly! As I always say, if a thing is worth doing, it’s worth over-doing...

If you were to offer kits of these, do you have a sense of how much you’d sell them for?

Really interesting! would it be possible to have the 12-18 dB/oct option?
The 18 dB/oct hi pass (like neve's) is very musical on bass, kick, and many other sources.

Hi Guys,

nice to see some interest in the BF-500 ;)

For 10 kits or more, I could make a small batch.

I started a list of the members who showed interest in the first post.

If you would like to buy a kit, please let me know and I'll add your name to the list.

Cheers
Gabriel

Very nice indeed,well done!
May I ask for a rough kit price in case you‘d get ten or more orders (haven‘t found any yet)?
I/O is balanced I guess,may I ask how (looks like INA and DRV,but it‘s hard to see from the picture)?


Thank you in advance,


Udo.

Hi Udo,

Yes the I/O is balanced using the INA/DRV combo.

I'll try to calculate the kit price this week  ;)

Thanks
