TROUBLESHOOTING

The EDITION BLUE-R 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 dealer.
The EDITION BLUE-R 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.
• 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).
The footswitch does not switch channels (30/60 only):
• The front panel selector switch may be in the LEAD position.
Set it to CLEAN (in this case, CLEAN = off ).
• The footswitch is not connected to the EDITION BLUE 60-R.
Plug it into the appropriate jack.

When accessed, the LINE OUT/LINE IN jacks cause
annoying hum (60 only):
• An electrical or magnetic field is causing interference. Use
higher-quality cables or re-arrange the cables you are using to
reduce interference to a minimum. If this still doesn't improve
the situation, use a DI box.
• The grounding of the connected devices may be causing
a ground loop. DO NOT SEVER THE GROUND
OF THE CONNECTED DEVICES UNDER ANY
CIRCUMSTANCES! Try plugging all devices into the same
socket via an AC power distributor/power strip. If this doesn't
eliminate the noise, you must ensure the connection is
galvanically separated by routing the signal through a DI box.
You have connected an FX processor to the LINE OUT
jack and the signal is totally distorted, even when you
have dialed in a clean sound (60 only):
• The LINE OUT signal is overloading the input of the FX
processor. Reduce the processor's input sensitivity ("INPUT"
or "GAIN").
You have connected an FX processor to the LINE OUT
jack of the EDITION BLUE-R and the signal's volume
level is way too low (60 only):
• The FX processor's output level is set incorrectly. Turn it up.
