Will do, I'll check it out later tonight, but i bet dan has built one, and every time he gives me advise, he seems to hit the nail right on the head, i'll email him and ask him to come here and give us the rundown. the idea of 8 channels seems pretty sweet!

Let me see if I can help. I am a fan of great filters!
The Harrison Ford Filters are very nice sounding and easy to implement in any studio. They are also a pretty easy DIY build. They are based off of the original filters in the Harrisons. 8 channels fit in a 1U case with DB25 connections on the back for IN/OUT. Very slick IMHO! I have a Roll Music Systems Folcrom that I sum through while I am rebuilding my little Neve console. I have 8 channels of the filters in between my DA and the Folcrom for mixing. Works very nicely. I know Marc at Strange Weather Studios has 16 or maybe even 24 channels of them and loves them. His studio is amazing!
They are not transparent in sound. But they are not ugly or overly colored at all. To me they add a little vibe. The filter range covers a lot of ground. If you turn the HPF and the LPF all the way up you can almost cut out all of the sound. So you can do some subtle filtering or some pretty extreme stuff with them. They work great on Guitars, Synths, tightening up kicks and a bunch of other things. Once I get my Neve back in the studio I may build another rack of them if they are needed. But I am getting by now with the first 8 and my Missing Links.
Because the HFF's are IC based they can be modded a little to personal taste. Over the years I have spent a bunch of time listening to different IC's and 2520 op amps. I do this so I know how to tailor my personal gear for a sound I like. I started trying my favorite IC's and I found an IC I like for these a little better then the stock IC. But, I do remember liking the stock IC. I found the upgrade IC to be a little punchier then the standard IC for the filters and I installed that in all 8 channels of them. The original IC sounded good and has a vibe to it for sure but I liked the slightly more modern sound I got with the upgrade chip. I will have to pull mine out of the rack or see if I marked it down in my build notes if anyone wants to know what IC I used. I also remember finding another IC that was to modern and fast. It was much more clear but lacked vibe. So I landed in the middle with my choice.
So if you like variable filters these are a great option. Honestly, I see these as a piece of gear that fills a big hole but, for some reason hasn't caught on like it should? Kind of like the Send n Blend unit that Serpent Audio and I have worked up. Great stuff for any studio.

So - are you talking about more than just Hi cut, Lo cut?

Nope just 8 channels of HPF and LPF. They are sweepable. If you need more, I HIGHLY recommend the Great River Harrison EQ's. Those are probably my favorite all purpose 500 series eq. Sound great, super flexible and of course the fantastic HP and LP filters.

Frank, after exchange rates and shipping I'd tend to think the CAPI Missing Link might be a better value. Thoughts? |

I'm pretty stoked up on the harrison ford filters now! Dans info is stellar on that, and 8 channels @ around $250! is silly! The circuit is based on the harrison 3232 filter section of that eq, as far as i can tell(?i was tired last night when i read GDIY thread), and also Brads piece sounds really cool, it's gonna have a deeper feature set, but less channels. If he can get 20 guys on board, he may go for it? A commit to buy thread is probably going to be set up some time soon.

I could offer some (original) Neumann W475.
I would like to clone them into API or 51X format.
Not well known, no reputation. No chance.
However, best what you can get.
One no go for a 500 clone is the 4 x 12 step switch.

I'm not familiar with it, and like you suggested, i cant find much with a google search, what would be the criteria before you would provide these in kit form or outright purchase? I am very intrigued by this!! Maybe do a feeler over at GroupDIY, and we can link this thread to that, to get a qualifying order count? T |

How did u come up with $250 for all 8? |

How did u come up with $250 for all 8? I saw it was 135 for the case, and 15 for 8 pcbs, i'm not sure where i got the idea it was $250? where did you see $100 pre channel? i cant find that either? lol! I will look at the BOM later, and figure out costs and post up. |

Dan emailed me and said roughly $100/channel.

I was initially thinking the same as you... $25-$30/ch in parts...maybe someone wrote that in the DIY forum, but probably missing some stuff.
Reality is that I could use 2-4 filters, but I don't need 8. Many of my pre's have HPF's... CAPI VP28, AML ez1073, etc... but would be nice to have a few more for the other pre's. Maybe I just need a pair of CAPI missing links.

Hey sic, found a cool pic of a channel, it is the harrison 3232 circuit copy btw. i'm not seeing to much an expense here? even if you add the psu and connectors? still seems high? But if dan said it, it must be true. he's yet to give me off advise, and he's graciously given me a LOT of advise.  |

I know the whole Euro / Dollar thing makes it cost prohibitive but I throw it out there anyway since there's not much on them. This whole area is gray...if you tally up the prices you aren't far off from other or better modules. For example if I buy two LC/HC modules shipping and converting the Euro to Dollar comes just 200 dollars short of the Elysia XFilter which has comparable LC/HC functionality as well as two parametric bands, the only shortcoming being that it can't be used on two mono sources. Either a stereo source or a single mono source but you get the idea. Same with the missing links...They're pricey but they offer additional functionality. I'm not good with an iron so I'd have to have them built. They run what, $650 built I think? And I'm not even sure if that includes the op-amps so again a pair runs at least $1300 but you're getting the built in fade which is a whole different functionality which if you need it, it's worth the extra money. I do like them and especially the fact that they're stepped but I tend to use very clean pres so I'm not in the habit of needing volume attenuation because I don't tend to push my pres, so it's pricey for me because I wouldn't be using the fader as much. But if I had a pre that could use it like the API 512, then those would be worth every penny to me! This is such a hard area to build for because there's a minimum price where you can build it and still make a profit and it's not far off from much more feature rich 500 series modules. Even the Shiny Box Guillotine, at $500 a piece seem a bit pricey for just filters but have a huge range and are amazingly recallable. But they're still limited at that price by not having adjustable slopes. I tend to like my high cut filters to be -6 because they're more useful to me gently rolling off high harshness. I haven't seen any real info on these - but these look great as well: www.rtzaudio.com/PEQ1549.htmlI'm not sure what they are going to go for but they have High and Low cut filters and are stepped and come both with Lundahl transformers and transformerless for those who like 'em cleaner. They definitely have my attention as well. They look like a great choice for a recallable channel EQ with cut filters. Regards, Frank |
