Default ICEpower preamp?

How will ICEpower handle a little offset on the pre amp output (few mV)? Is the input AC-coupled?
In datasheet it is not mentioned directly, but bandwith is stated from 10Hz, not 0, so it might be AC-coupled?

How about DC-protection, if my preamp breaks down and sendt e.g. +15V DC into ICE input? Will my loudspeakers be destroyed? Will the ICE module?

Any knowledge or experiences?

The ICEpower modules have DC blocking like most other classD modules. More specifically it's just an input cap.

I think that answers all your questions.

Hi again,

I have been trying to track the input cap on the board (ASC200), but I can find it (or them, because if it is differential, then to identical caps must be present?)

A electrolytic (10uF/16V) seems likely, but again only one....how can that be?
