Not sure what you’re saying Trever … a resistor in the mute delay circuitry (cct=circuitry?)
Think Axiom just doesn’t turn on the amps till the power supply is up … if that is what your thinking

A soft start circuit allows the fields in the transformer to slowly build up.
If there was a soft start circuit in there your lights wouldn’t dim and the amp wouldn’t make as large a sound on startup (if any).
