Arjen TA2020 Help needed

Quba123 · 7th February 2012, 09:47 PM

Hi! bought the ta2020 MkIII kit from arjen a while ago.

I wired it up yesterday and im sure that i did the correct wiring. But there is a problem.

The powersupply that was supplied with the kit, when started the led is flashing on the power supply. and a clicking sound from both speakers and the relays is appearing. Its like a pulse. The same is for the Power LED on the arjen Board and the Over LED. I have video of it if requested.

Please help me, im just a beginner

something is shorting/drawing too much current - it's the protection kicking in. Mine did it when I was messing around with different LEDs. Double check your wiring.

Post a nice clear photo of your build and I can check for obvious errors. Also look for my post a few pages back - it has a good wiring diagram drawn by Arjen.

Next thing to do is take things out of the equation - try just the board and the psu (disconnect the speakers and inputs)

Then add things back one at a time till you get the problem again.

Edit:

Here you are - this is how the input side should be wired

Thanks! ill try it, im quite surtain that i did the input right, i have no channel selector so its simple.

Thanks for the advice! found the problem, Took out my potentiometer and the voltage from the powersupply was like 1,5 volts.. so i adjusted it and it works perfectly!

the short/problem will be on your 12v circuit somewhere.

does the PSU flash when it its plugged in on its own not connected to the amp?

Quba123 · 7th February 2012, 10:25 PM

Its fixed now! haha the voltage was turned down to 1,5 volts on the smps so, now i turned it up to max and the smps led is no longer flashing, the Power led for the amp board is fluid and the OVER just flashes for a milisecond when starting (i hope that means ok) So no problems! thanks for the advice tho

check the dc output with a multimeter if you know how just to make sure it's sitting nicely at 12v. The ta2020 can take a bit more voltage and I doubt that the PSU Arjen supplies could damage it but its best to check it.

Well, it's sounds good at the moment. Yes, i doubt that he will supply the costumers with a fault smps
