Does anyone know of a stand alone HPF?

[auxpot]

there are vintage german modules....neumann, bfe, lawo etc....

[Mono-Peter]

check out the old ones from Siemens and Telefunken (W293/294 or W393 /394). Or the passive ones from Eckmiller (HS10 / TS10). Great stuff and cheap!

Cheers!
Did a search for Eckmiller and can't find anything. Do you know the web address? Who's doing them in the UK?

Hi steve, this is all vintage gear. Eckmiller does not exist any more. But you can get the modules relativly cheap on German Ebay. Do a Google research, I prefer the Siemens filters, as they do a great job and give a certain colour to the sound, I like it for electronic music, synth stuf etc...

I looked for that for a while too. Not much luck. Although one production EQ designer did send me specs for a standalone variable HPF that I could wire up myself, I never did it. Went with a Weiss EQ1 instead, since I needed the rest of the functions anyway.

About the most convenient and cost-effective analog approach I found was to buy a used Klark Teknik DN410. Very nice, clean equalizer for cutting if desired, but all bands are individually defeatable and the unit can be used only for the variable HPF and LPF. 2nd order, but works very well and doesn't jack with the tone just from being in circuit. $400-600 or so, reliable, lots of them in the field.

Don't know the slope of the filters but I've found the API 215L's to work very nicely for my applications... they're 200 series frame size but personally I like the pre's in the 200 series as much as the 500 series pre's and the 225 compressor a hell of a lot more than the 525 compressor so over time, as you fill up the frame... you should be able to warrant the expense of that frame.

Peace.

Yeah cheers Fletch, I had looked at those but two things put me off. 1st having to buy yet another rack format and the slope is only a second order 12dB/OCT. I prefer the steeper 18dB slope on the low end. The filters on my Massive Passive are wonderful but thats being used on other things.

I've just noticed that the SSL X-Rack mic pre module has the Filters I need and the line input can be used on mixdown so I might try a couple of those.

Might ask them if the HPF is active in line mode. I have some preamp/EQ units where the filter only applies to the mic pre input.

Shiny Box has plans to release both a 500 series LP/HP filter module and then an 8-channel 1RU version a little later next year. I'm not sure on the slope though. You should contact Jon at Shiny Box.

I'm fairly sure they are. No good to me if not! Jim are ya out there?

[Jim@SSL]

Yup - you can use them on the line inputs.

Cool, looks like Santa will be bringing me a couple of SuperAnalogue Prez

[stevetgn]

Jim, just to clarify.

The line in on the mic pre could also be used like the 4 way Line Return modules (albeit only one input) by pressing the Rec buss buttons and then summing Rec buss to the mix buss on the master module and therefore giving you extra X-Rack inputs on mix down, yes? Does that make sense?

Yes interesting indeed. I believe I posted this idea at least a year ago. I requested an 8-channel high/low pass filter box, analog. Looks like somebody was reading that thread, which I can't remember at all right now. I don't recall if I also suggested the 500-frame modules, but I definitely remember posting the 8-channel idea.

I suppose somebody else could have thought of it on their own, as I do not have a monopoly on ideas.

Anyway, whether I get credit for the concept or not, good going Shiny Box. I'll have to check those out when they're available.
