I all the channels tested and forgot to take a picture. When it's on the only light that's on is the blue power light, unless there's a signal to any of the channels. However, when you turn it off the lights stay on for a little bit while the caps drain. This thing is a monster. No real frills, no nonsense, a mix of passive and active cooling to keep the weight down. The thing weighs 80+ lbs with a massive amount of heatsinking or unnecessarily thick panels. If this thing only did passive cooling it would weigh 120+lbs easily.
