6.0 TROUBLESHOOTING

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
