Need help getting T2020 amp working

[NdMk2o1o]

Got an T2020 based cheap amp off ebay and it came today, now my idea was to use this to drive my headphones AKG 701 so I also bought an 3.5mm audio jack>2x Phono to hook up the 3.5mm to my Xonar and the 2x Phono to the amp, now when I do this and plug my cans into the mp3 input cause there is no where else to plug them, I get sound but it is just bypassing the amp as the bass/treble and volume knobs do nothing. I am no audiphile but is there something else I need to do or can I not play my headphones through this amp?

There isn't anywhere you can plug your headphones in? Because it doesn't baffle me that it doesn't work right with the mp3 input...

Kind of thought that now I have it, though didn't think about it beforehand.

The seller said this in the ad:

RCA Input ,can be used as Ipod,MP3/MP4 headphone amplifier

Though upon reading it again I can see I might have misinterpreted it as an headphone amplifier

 

[scaminatrix]

Does it have a USB input aswell as RCA's? What connections does it have altogether?

 

[NdMk2o1o]

Just these:

Oh man, just looked it up. It's a car amp. To fit speakers to it, you need bare red and black wires (speakers)

^^^ Ninja'd!

You can get some tools and start modding, or see if you can get a converter that's headphone jack on one end and red and black speaker wires on the other

What are those speaker wires called?
Thinking bout grabbing a cheap tube HEADPHONE amp on the bay but shipping is going to take yet another week/2

Easiest and cheapest fix is this: I don't know if you're headphones have a balanced or unbalanced input but here you go anyway (my paint skills are better than my describing skills ). I think this is how it works anyway

I can get these cables made custom by the guy at my local electronics shop. I don't think there's a name for it.

the 3.5mm would need to be female or whatever the opposite is to what you have drawn

Also I dont mean the name of the custom cable but the proiper name for the speaker wires with a red and black wire

 

[scaminatrix]

Yea sorry lol I just realised it shoulda been female!

It's just speaker wire by the looks of the webs. Have you got a link for your earphones? I need to see a pic of the jack.

What do you think?

 

[scaminatrix]

I wouldn't buy that thing, I'd just try and get what you've got running first (the cheap way anyway). I'd just find a 3.5mm jack extension lead, snip off the male end, strip the wires and conect them to your amp. Plug headphones in the female end and you're away.

Only problem you might have is finding the right type of jack. You want the jack that matches your headphones like this:

note the 2 plastic bits separating the metal parts on the end of the jack. If you find a 3.5mm extension lead and the male end has the 2 plastic bits, then the female end will have them on the inside too. This is crucial

Up for some cable modding?

Maybe dont wanna mod my phones as the cost £175 and also dont want to fry/blow them

Na, I've worked on tons of car amps and wired up subwoofers in motors etc. I've done all sorts of stuff throught trial an error and I've never blown anything (touch wood). Just keep it at a low volume when checking the wiring polarity etc. If you've got a cheap pair of earphones there, like phones ones or something, use them while you're checking.

One of these would be my favourite starting point:

Would be a piece of p*ss if you could start off with a cable like that.

Do I need to buy any more cable aside from that?

 

[scaminatrix]

Na, if you got an extension you could do it without buying more cables. Oh see what you mean, na the cable above on it's own would do it.
But, you could do it "mod-free" this way.

One of these:

One of these:

And two of these (because I couldn't find a female phono to female 3.5mm):

You might be a genius, looks like that could work

 

[scaminatrix]

Nice one Na not a genius, just a work-around king I've done some dodgy stuff. Wired up the amp in my old Escort with Dyson hoover mains plug wire once...

 

[NdMk2o1o]

Can't get them ANYWHERE

[scaminatrix]

Just pissed off I have to wait, YET again, waited 2 weeks for the amp to come from HK and my phones are seriously underpowered without it
