Hi Sean, thanks for your response.
The amps are normally on. Being power amps they have just a mains power

But, if I need to power

The behaviour sounds exactly like the power circuit breaker is kicking

AFAIK, the breaker should only kick in where there is a surge, not a

Thanks again. There's no mention in the manual about any such circuitry,

It must be the FW upgrade path then. Can you try this if it isn't a

- then install 7 and see if it works
It can be only explained if that Fw31 isn't the same as the one in the

It's hard to guess what's going on here without knowing exactly how the
sensing is implemented in the amps, but it sounds like the amp might be
sensing when the signal lines are floating, and this triggers a
power-down. What is odd is that it does not power on again after the TP
has reset.

No cable with RCAs is close to 75 ohm.
