6.1 On LED Flashing Sequences			6.2 Examples of LED Sequences
When switching on the amp the Power LEDs flash twice accompanied by a			LED sequence:	Ch1 : …XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-…
flash of clip LEDs. This is normal for the ‘Start’ sequence of the VORTEX.				Ch2 : …………..Permanently lit……………
			Failure:	Ch1: high temperature with signal attenuation
When switching off the amp the Power LEDs flash several times followed by a				Ch2: normal operation
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.)			LED sequence:	Ch1 : . . X-X-X-X-X---X-X-X-X-X---X-X-X-X-X---
				Ch2 : . . X-X---X-X---X-X---X-X---X-X---X-X---X-X---. . .
In the following table you will find the possible LED sequences of the ON-LEDs:			Failure:	Ch1: DC, power-stage defect
				Ch2: main SMPS off
Operating Status	LED Sequence (X) = flash, (-) = off	Description of repeated sequences
Normal (no failure)	Permanently lit
Power fail	. . . X-------------------X-------------------X-------------------X . . .	Short 50 ms flash + 950 ms pause
(i.e. switch off)
High Temperature:	. . . -XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-…	750 ms flash + 250 ms pause
signal attenuation
Over Temperature:	…X---X---X---X---X---X---X---X---X---X---X---X---…	250 ms flash + 750 ms pause
main SMPS off
DC:	…-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-X-…	250 ms flash + 250 ms pause
reason unknown
DC:	. . . ---X-X-X---X-X-X---X-X-X---X-X-X---X-X-X---…	3 * flashing + 0.5 s pause
input-signal-fault
DC:	. . . ---X-X-X-X---X-X-X-X---X-X-X-X---X-X-X-X---…	4 * flashing + 0.5 s pause
fault in driving-stage
DC:	. . . ---X-X-X-X-X---X-X-X-X-X---X-X-X-X-X---…	5 * flashing + 0.5 s pause
power-stage defect
Power-stage defect	. . . ---X-X-X-X-X-X---X-X-X-X-X-X---X-X-X-X-X-X---. . .	6 * flashing + 0.5 s pause
without DC
Main SMPS off:	. . . ---X-X---X-X---X-X---X-X---X-X---X-X---X-X--- . . .	2 * flashing + 0.5 s pause
(unless Hi Temp/Power Fail)
