Correct retyping from from front panel is about the only way to reset to factory.

When I say DSP's I was referring to DSP speakers, which it sounds like you don't have.

I have read on this forum in the past if you don't have the A013's setup correctly you can have issues (correct slots and correct jumpers). I'd compare your setup to what 861 mconfig recommends.

Note that both my suggestions are reaching as I don't know what else to suggest and is what I'd try if I were stuck in the same situation.
