The LUCIA amplifiers do not have a power switch, the amplifier will turn on automatically when AC power is connected to the unit.
The unit will go into standby mode if no signal is present at any input for 20 minutes.
When in standby, the amplifier will power up in 0.9 seconds when a signal above the pre-set threshold, -54 dBu default, is present at any channel input.
Please be aware that to avoid issues with the signal being too low relative the threshold it is generally better to use full level from the source and to reduce the gain in the LUCIA
instead using the front controls, GPI or in the matrix.
