Problem driving Martin Logan Ascent i's

Your Krell has plenty of power and current for the Ascent i's. Make sure the power cords are plugged all the way into the speakers and that whereever these are plugged into, hasn't tripped a breaker or a relay.

You might need to pull the power board out of the back of the speaker and see if the fuse has blown inside.

Martin Logan has excellent customer service. If you can't figure it out, call them.

Are your speakers plugged into an electrical outlet? Is the little light in the front of the speaker lit? Sometimes the Martin Logan power cords can become loose over time.

Thank you for all the responses. I posted this for a friend. He was pushing the Krell S-300i to the point that it was not clipping. The thermal protection circuit was kicking in. 8 hrs straight, heat became an issue. We added a sub and it is sounding wonderful. Again thank you.
