I may be interested since I missed on the last run.

Can you remote control them?

You'll need to build your own controller for the attenuator. (i.e., an arduino) You can add remote control functionality to it.

I have never played with an arduino; I guess I may have to sooner or later.

I was considering about making another batch of bare boards.  Anyone else want to join in?

is there a compelling reason to run boards for this one over the amb or twisted pear offerings

I found the TP JTree to be a bit of a hassle to implement right. Heck, I'd rather take TDK instead.

 

What I'm anxious to try are the PGA2320 chips.

If that's the case with commercial offerings then sure I'd be down to grab a few attenuator boards.

I've built a simple circuit with a PGA2310 which is very similar to the 2320 but comes in a DIP16 package. The only things I haven't done yet are figure out the input and output impedance and how well balanced operation would work.

The AMB attenuator is pretty good:

I've used the PGA2310 and the PGA2320. They are pretty good but I can never get them to be quiet, there always seems to be some noise.

Yes,

I'd be in as well if you go a head.

I have a few extra boards.  PM me.

PM sent.

Anyone have used the KG Digital Att with Pot/Vol/Bal controls for an amp. If so how did it work out.

What did you use for controls. Want to do it but was interested if there were

any snags found.

Thanks

Les

Just finished my two boards and wanted to say thanks to Kevin/Kerry and stv1756 for their valued contributions.

Assembly was straight forward and for a guy with buggared eye sight the 1206 smd were great.

My pair are for my T2 and will be balanced arrangement. The code worked well and absolutely thrilled.

This is my 3rd KG project that's worked first time and above expectation.

Les

we aim to please!

Anyone had experience with the smt version attenuator in the board dump?

Is the board verified?

finally cleaning up, i have one extra set of the original attenuators, part of the buy that

kerry did, professionaly assembled, and i tested them last night, so if anyone is interested

i can sell that pair. Price is whatever kerry charged, which might take me a while to look up.

I'd like to buy

If I remember correctly they were around $97 $99 ​per board.

I'm going to review the new smt version of the board and order a couple so I can test it.

 

EDIT: I just checked on the price of the original assembled boards.  I have a set sitting in front of me that i'm putting into my BH build.

I'm interested, count me in for one set please.

I was just looking at the 24.3K BOM and Mouser, and it appears that Mouser doesn't stock 6 of the resistor values anymore (in the IRC/TT PFC 1206).

 

If anyone has already worked through this problem, let me know.

 

Also, I assume that this version of the attenuator (Kerry group buy, 24.3K impedance) would work fine with the Multiamp?

 

Timely, I know

for multiamp, you really want the 10k version.

I'm also interested in a set if you're willing to do a run, what impedance are you aiming for?

Is it still an issue if using FET input? I believe the 1st BOMs were for 10K? I presume the Rt termination resistor = 10K is what I am looking for?
