McCormack DNA-1 Problem. Help, please

Hi All,
My clean looking DNA-1 came in yesterday. I got it from a well rated A-goner who said it was functioning perfectly when shipped. It came in very will packed with no sign of damage. When I hooked it up to my Thiel 3.5s to try it out the red protect light on the faceplate came on along with the green power light. I assumed that indicated a problem so I quickly switched it off. I have searched on line for a manual with no success. So, is it a problem? Or should I have not chickened out and let it continue to run. If it is a problem, given that I had not even turned the pre-amp on, could it be something to do with the Thiel equalizer which is on all the time?
Any thoughts (or leads on a manual) would be appreciated since I was really looking forward to hearing how it sounds and don't want to contact the seller untill I'm sure I'm not doing something wrong.
Thanks in advance.

I have a DNA-2 and that is how it powers up. I think it is fine. The red light should go out after 10 sec. or so. It will also go into "sleep" mode with no signal present for 30 min or so.

It should go out in 5-10 seconds. But why not go to Google first and get the manual? It's the first link when you search for McCormack DNA-1 manual. (Instead of getting a lot of other people involved unnecessarily and probably making the seller squirm a bit)

Hello Drjay -

The DNA-1 (and DNA-0.5, DNA-2, DNA-HT1 & HT2) comes on with the Protection engaged. This lights the labeled red LED which will gradually fade out as the amp warms-up and comes out of protect. This should take less than 30 seconds. The amp will stay in protect mode if there is a fault condition, like a blown internal fuse or excess DC appearing at the input.

So go ahead and turn it on - it sounds like it's working properly. The red LED should fade out and the music will appear, as if by magic ;-)

Best regards,

Steve McCormack

Hi Drjay

Can you check all the fuses in the DNA-1? When I purchased a DNA-1 from a reputable seller and when I powered it up it had a red light. A fuse was blown when they were testing it before it was shipped to me. Normally when a McCormack DNA-1 or DNA .5 is powered on the light is first Amber and then turns green.

Also I have a pdf copy of a DNA-1 manual. I'll contact you to try and work out a way to sending it to you.

I have a DNA-1 Rev. A, when I turn it on both the blue and the red light illuminate, after 5-10 seconds the red light fades and the music starts. From what you've posted it sounds like your amp is working normally. Hope all is well, it is a fantastic sounding amp, you're in for quite a treat.
