6. On LED Flashing Sequences
When switching on the amp the On LEDs flash twice accompanied by a flash of
Clip LEDs. This is normal for the ‘Start’ sequence of the VORTEX.
When switching off the amp the On LEDs flash several times followed by a
flash of Clip LEDs. This is normal for the ‘Shut Down’ sequence of the VORTEX.
(It is the same as the loss of the mains voltage.)
In the following table you will find the possible LED sequences of the On LEDs:
