petervfunkster Posted February 3, 2009 Share Posted February 3, 2009 hey My akai deep impact after about 20 minutes bypasses the effect even if the effect is turned on, it just plays a clean tone and the input signal is not reading ? has anyone else come across this problem?

Kiwi Posted February 3, 2009 Share Posted February 3, 2009 Problems with the power supply perhaps? Is the power socket detaching from the PCB, causing momentary blackouts and resetting the pedal? Quote Link to comment Share on other sites More sharing options...
crez5150 Posted February 3, 2009 Share Posted February 3, 2009 Are you using the Akai supply that came with it.... I tried to run mine from a different supply once and it caused all sorts of weird problems.... went back to the Akai one and they disappeared Quote Link to comment Share on other sites More sharing options...
alexclaber Posted February 3, 2009 Share Posted February 3, 2009 I too noticed that the Deep Impact does not like to be run on other 9V supplies (I think the Akai power supply might actually be 9.5V?) Alex Quote Link to comment Share on other sites More sharing options...
Toasted Posted February 3, 2009 Share Posted February 3, 2009 I think I've got an AKAI PSU. I don't normally go in for "this 9V is better than that 9V", but in the case of the AKAI there seems to be some kind of black magic. Quote Link to comment Share on other sites More sharing options...
petervfunkster Posted February 3, 2009 Author Share Posted February 3, 2009 cheers folks for the speedy response! you may all be right - I bought mine on ebay so it came with the american akai power supply and Im using a boss 9V, I'll see if I can source an AKAI PS P Quote Link to comment Share on other sites More sharing options...
petervfunkster Posted February 3, 2009 Author Share Posted February 3, 2009 another question - is using a different power supply thats 9v potentially damaging to my deep impact? Quote Link to comment Share on other sites More sharing options...
cheddatom Posted February 3, 2009 Share Posted February 3, 2009 Can't you plug the american psu (with an adaptor) into the mains? That should work. Quote Link to comment Share on other sites More sharing options...

Is the LCD display showing partially lit sectors? If so, this would suggest a short has happened somewhere. Quote Link to comment Share on other sites More sharing options...

That should work.[/quote] Only if it's a regulated SMPS which I don't think it is. I've had two Deep Impacts in my time and although it's a while since I sold them I do recall there being something unusual about the PSU voltage, I think that it was closer to 10V than 9V and due to the digital circuitry the pedal had a habit of freaking out when run from a lower voltage 9V supply. Great sounding pedal, horrible reliability issues. Alex Quote Link to comment Share on other sites More sharing options...

But I do know I have several AC-DC convertors that have american plug on and I just put an adaptor on the end. Am I risking anything? In particular two laptops and a 9v DC pedal supply.

petervfunkster Posted February 4, 2009 Author Share Posted February 4, 2009 so.. I got the original american AKAI power supply that came with it, and after a minute it cut out with a smell of smoke! disaster! The deep impact itself is fine.. It seems to be working now with the BOSS 9V power supply, I was daisy chaining it with a distortion previously so maybe that was the issue? I know the korg microsynth manual specifies no daisychaining.. Quote Link to comment Share on other sites More sharing options...
Toasted Posted February 4, 2009 Share Posted February 4, 2009 Let me see if I can find my AKAI PSU. If I can you can have it for free. I'll PM you in the next few days if I have it. Quote Link to comment Share on other sites More sharing options...
Rich Posted February 4, 2009 Share Posted February 4, 2009 I lost my Akai PSU in my last house move, so I've been using the PSU from my old Digitech BP80, which seems to work fine. It doesn't like any of my other 9v PSUs though. Verrry strange. Quote Link to comment Share on other sites More sharing options...

eshears Posted February 8, 2009 Share Posted February 8, 2009 I've always used my Deep Impact with a Godlyke power supply and have never had problems. I did have a smiliar issue though with the effected sound cutting out. I had to have some broken solder joints resoldered, and it's worked fine ever since...
