6.0 TROUBLESHOOTING

6.1 If the VORTEX™ will not switch on:
• The amp is not getting any AC power.
Check the mains cable to see if it is connected
properly.
• The mains fuse is defective. Replace the fuse
with another identical fuse. If this fuse also trips,
consult your Hughes & Kettner
6.2 If the VORTEX™ is connected properly,
but no sound is audible.
• One or several GAIN and MASTER controls
may be turned all the way down. Dial in
a higher setting.
• Never overlook the possibility that the guitar
cable may be damaged. Try another one.
• A short circuit in the speaker signal chain may
have tripped an internal fuse. Make sure none
of the connections are shorted out and have
a qualified service technician replace the fuse
(identical specifications are a must).
6.3 If the CLEAN channel will not activate
via an external footswitch:
• The footswitch is not connected to the
VORTEX™. Plug it into the appropriate jack.
• Check whether the footswitch is the correct
type. We recommend a Hughes & Kettner
