Biino Mk2

[thimios]

Looking for a solution for volume control.
Here is the biino Mk2 ver.
I found the time to assemble this in the end!
I don't use the input sellector board, only the volume control.
I have chouse the constant input version.
Not sure if it is the right option.

Here is a pic of my own Biino as well as distorion test. I find much better and lower noise than LDR attenuator.

Interesting results , i want to run a distortion test.
Now i know that i won't be disappointed
Did you connect this behind a power amplifier?
Are the pop's audible, especially when try to increase the volume very fast using the i.r remote control?

No problem with pops on mine. There was a problem with the bom showing 3.16k ohm instead of 31.6k ohm (Now fixed). I am very happy with the silent background low noise from this design.

Where is the problem, in the constant input or in the constant out version?

 

[niss_man]

I didn't know there were 2 versions. There is only one bom on biino website.

 

[thimios]

No there are two versions and two bom.
First is the constant input.
Second the constant out.

 

[niss_man]

The second schematic isn't on the website. Maybe it used to. I used the first schematic 10k.

 

[thimios]

That is the ver. i used too.
Constant input.
There is the right value 31.6K.
Did you placed this behind the power amplifier?

 

[niss_man]

Yes I use this with my diy 250w class ab power amp.
