stepped attenuators? What should I get from the ff. choices?

jarthel · 30th June 2002, 12:45 PM

1. Goldpoint
2. DACT
3. TKD

Well I was thinking of DIY but I need suggestions for assembled ones.

Thanks

Hi jarthel,
Please see the links:

Elma, DACT & Goldpoint look very similar to me. I wouldn't thrust these any more.

Marchand Electronics may have just what you need. They offer passive preamp kits as well as just attenuator assemblies, with either 23 or 46 position switches. What's more, they use the Shallco rotary switches with coin silver contacts, one of the best in the business (used by Ayre Acoustics on their high end preamp).

I have a PR41 passive preamp from Marchand and have been very happy with it. Phil also offers a special balanced version, and it's my plan to build an active preamp using the switching, balance, and attenuation controls with my own active circuitry (NLFB class A solid state) in a nice Par-Metal aluminum chasis.

Regards,

Jon

Jarthel, for the third time in the last few days, you are asking questions that have already been answered because you didn't search previous posts first, and you ask the same questions to multiple forums, including some of the headphone boards. Please stop doing this.

If you had searched for stepped attenuators you would have found this thread, which contains the following info, among other things.
Pots

Morsel well I know made those links in head-fi but wasn't exactly seraching for DIY stuff. I'm after already built ones.

Also, I asked my question in different forums. That means that there are people who frequent a forum and not the other ones. Don't assume that because you frequent the forums where I made my post, other people will see it.

There are 4 I know of.
Shallco
DACT
Goldpoint
TKD - available from Michael Percy www.percyaudio.com

Anything else will be a kit or something you fabricate yourself.

There are also transformer controllers from Stevens and Billington, Sowter and Silver Rock.

Sorry, guess I was in a grouchy mood. There have been many posts of that nature lately and I happened to let loose on you.

FBJ · 2nd July 2002, 05:53 PM

Don't feel bad morsel, I have suggested people to use the search before too but I still see new threads with questions about basically the same subjects.

carlmart · 2nd July 2002, 06:42 PM

In fact doing a good search depends on how you make your question. Though I don't see why it's so much of a problem to put your question in different forums, as not many people go see them all. I don't care.

About the stepped attenuators, the TKD is not really a step attenuator as far as I know. Just a regular pot with position steps, but not resistors that set the levels. Am I wrong?

Strange thing about an Elma switch rot, as the AA mail reports, as they are inside. Perhaps there was a problem with the terminal. Not an usual thing anyway.

The switch I bought some time ago, from The Parts Connection, was an Electroswitch which allows assembling it as a ladder attenuator. That arrangement puts just a few resistors in series/parallel with the signal.

Well TKD has a stepped attenuator and a pot (but it looks like a stepped when you open it). If you have Percy's catalog, check it out.

Also, I made my search but nothing really interesting came up.
