If it has the banana speaker output's on the back, it is an "A" model and bridges 800w into 8 ohms only.
The "B" model had speakons and still bridged to 800 w but @ 4 ohms iirc.
The "C" model has speakons and bridges into 1100w @ 4 ohms. This one also has the "porch light". The Eden logo on the front is backlit when the amp is on.
Where it gets confusing is there were revisions to the "A" model that were labeled.... yep "B" and "C".
I've had the "A", and currently have the "C" model.
Hope this helps.
