Flange schematic

[amelecsol2000]

Im looking for a Flange schematic to add to an amplifier im building.
I have searched for a couple of days with no luck. Any info or advice would be appreciated.

Do you mean flanger?

Hello,
Thank you for your reply.
Yes flanger is what Im looking for.
I have not had a chance to look through these links you posted for me but I will tonight.
Again, thank you.

The problem with analog flanging is many of the CCD's used for the delay are no longer available with all the low-cost DSP products.

I have had a rough time finding a few of these components such as the MN3101 etc.
Do you know where I can find a digital schematic?
Any info or advice would be appreciated.

Thanks

The problem with digital is the software/firmware to run it. Anymore its easier and probably cheaper to buy some kind of digital effects processor.

A short delay with delay time sweep (what flanging is) isn't all that hard to implement in DSP, if you have experience with assembly or C language.

Several DSP manufacturers (Analog Devices, TI etc.) have inexpensive DSP evaluation boards with assembly language editors/loaders which you can play around with if you're really interested in "rolling your own" DSP. They are kind of fun.

Other than that, you are looking at R&D expenses far beyond what a new effects processor would cost.

I have no idea if there would be enough of a market to pay for the expense of developing a board level DSP that could be added to an amp or housed in an external enclosure. Might have to think about that one...

Good luck

It is hard to believe that you couldn't find MN3101. I found it in the first shop I checked: http://sklep.avt.com.pl/go/_search/f...y_words=MN3101
The site is only in Polish but you can see that they have both MN3101 and MN3007. They also sell "chorus" kit, which includes both of the ICs: http://sklep.avt.com.pl/p,pl,48309,a...o+montazu.html .
I can't believe that you couldn't find the ICs in the States.
You can also take a look at: http://www.tonepad.com/project.asp?id=26 . This is flanger build on MN3101 na MN3007.
If you want a digital version, you can take a look at: http://www.spinsemi.com/products.html . With this IC you can implement almost every delay-based effect, including flanger.

Marek

Sorry about not getting back to your replys sooner, I was side tracked.
I want to thank everyone for your help and advice. Some great links that have been useful.

I Thank you all
