Volume control question

[Biggie1494]

Hey guys 🙂

So I was wondering, I wanted to buy this little amp as a weekend project;

NEW TA2020 Class T Audio Power Amplifier/AMP Board | eBay

But I don't see any volume controls? 😕
Would I need this volume control kit to go with it ? Or was there something I skipped over on the board? :/
An would this kit be compatible with the amp?

DIY Kit--LM1036N Fever Volume control board Kit for DIY (12V DC/AC power supply) | eBay

Sorry if this seems like a dumb question, I'm still learning !

Cheers 🙂

There is no volume control, you supply that. All you need is a stereo pot of 20K or 50K, simple!


looks like a nice board

The LM1036 has quite high distortion 0.06%, this is high in comparison to a potentiometer. You would be better to use a dual-gang pot., logarithmic, probably 10k, depending on what you intend to drive it from, although you won't go far wrong with 10k.

There are 3 connections per pot, you wire the one nearest to fully clockwise to the incoming signal, the one nearest to anticlockwise to incoming ground and ground on the amplifier, and the middle pin to left or right signal in on the amplifier.

Edit: 20k or 50k as Pano suggests will also probably be acceptable.

Oh so there would be no point in getting the DIY volume control kit?
And where would I connect the stereo pot to?

Thankyou for the quick reply 🙂

Okay that's great! thanks for your reply 🙂

If you find my explanation confusing and it works in the wrong sense, just swap the outside connections.

Yeah I've been reading through your answer a few times now 😕 haha once I get the amp ill play around with it a bit and see how things go 🙂

Yeah, if you look at the pot with the spindle pointing towards you and the connector pins at the bottom, then the ground connections go on the left-hand pins, the signals on the right hand pins and the connections to the amp are the middle pins. But like you say, once you get the amp and wire it up, it'll become obvious if it's getting quieter when it should get louder, and it's easy to fix.

 

[Biggie1494]

Yeah, I understand what you're saying now 🙂 cheers!

Oh, an another question, If I wanted to control the gain, treble etc.. Would I then get the volume control kit? What would I need to get for that?
