Melbourne Daughterboard for M2X

[Vunce]

I have been using the eBay DACT stepped attenuators in my preamps. I think they work well and sound better than a pot.

I agree,
I’ve used several of them in my projects. They are very quiet, no clicks or pops changing volume. I just got done replacing the pot in my Aksa Lender preamp with a 50K Dact type

JPS64 was kind enough to make three different front-panel baby boards for just the volume pots. Now everyone can be happy! Thanks, JPS64!

 

[Vunce]

Very happy here
Volume pot type/location choices AND a second set of outputs also!!

Thanks X and JP!

 

[zman01]

JP and X, thanks for taking our request into consideration and implementing it into the design - very cool!

 

[xrk971]

Just don’t ask us to put in a high negative feedback Class AB amp core.

 

[Vunce]

Heresy!!

I found also this one and footprints are already defined!

Hi JP,
Is this the same as this item? Or same footprint?
I bought this but the click detents between each volume setting is so rough - requires a lot of force to turn that I have not bothered to install it yet. I’m sure mine is a fake Alps though.

[JPS64]

@X, stepper fits standard ALPS pot (2 additional holes).



Spending the day with vias!
Silkscreen after dinner.
Then DRC and ERC.
Perhaps, late this night first 3D view with enclosure?


P.S.: I´m recommending HIFI2000 GX343.

Hi BRN,
I think you were one of the first I sent - but let me resend.
Thanks,
X

 

[BRN]

Sorry I missed it. Payment just sent.

 

[JPS64]

Here the preamplifier (or HPA, 4p. dedicated connector to use). I´m using HIFI2000 GX343 enclosure (3mm front --> 27 EUR).


I´ll finish data set so that X could check precisely.
