VORTEX POWER AMP SERIES
P.23
6.1 On LED Flashing Sequences
When switching on the amp the Power LEDs ash twice accompanied by a
ash of clip LEDs. This is normal for the ‘Start’ sequence of the VORTEX.
When switching off the amp the Power LEDs ash several times followed by a
ash 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 nd the possible LED sequences of the ON-LEDs:
6.2 Examples of LED Sequences
LED sequence: Ch1 : …XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-XXX-…
Ch2 : …………..Permanently lit……………
Failure: Ch1: high temperature with signal attenuation
Ch2: normal operation
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---. . .
Failure: Ch1: DC, power-stage defect
Ch2: main SMPS off
