Hello to the Forum
I own this little good sounding Cyrus Q Power amp that I used for a while as a power stage for my TV. This amp is just intended for high quality AV systems since it has an auto power feature.
Now I've moved it to a music only desktop setup that I mainly use during working hours at very (very) low levels. Unfortunately when using it in this way it sometimes switches to standby and it needs me to slightly raise the input level or press the front power button to awake it back. The auto-poweroff input level is a bit lower than the auto-poweron (hysteresis), most probably in order to avoid continuos power cycles.
Does someone know if and how the circuit can be modified in order to disable the auto-power feature? I have jut verified that keeping the power button always pressed does not keep it always-on; the auto-poweroff has precedence. The button can only awake the amp if already in standby.
Cheers

It would be technically possible to make the music sensing circuit more sensitive or alternatively disable it with a minor circuit modification, however I can't locate a schematic online to be able to suggest what components to change.
You could also jumper the power relay contacts which would also defeat the front power switch, but the main switch on the rear will still operate.
