WARP 7-MANUAL
6.0 POSSIBLE ERROR SOURCES/
TROUBLE-SHOOTING
6.1 The WARP 7 won't power up when you switch it on:
•It's not getting AC power. Check the mains cable to see
if it's connected properly!
•The mains fuse is defective. Replace the fuse with another
identical fuse. If this fuse also blows, talk to your local
Hughes & Kettner dealer.
6.2 The WARP 7 is cabled up and connected properly,
but no sound is audible:
•One or several GAIN or MASTER controls are turned all the
way down. Dial in higher settings.
•Your guitar cord may be defective; try another cord.
•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 Your footswitch will not switch channels:
•You may have failed to connect the footswitch. Plug it
into the appropriate jack of the WARP 7.
•Check if you connected a suitable footswitch. We
recommend the FS-1, another great product of the
Hughes & Kettner range of accessories.
6.4 When in use, the FX-SEND / FX-RETURN jacks
generate annoying hum:
•An electrical or magnetic field is causing interference. Use
cables of a higher quality or rearrange the cables you are
using to reduce interference to a minimum. If this still
doesn't improve the situation, use a DI box.
•The connected devices' ground circuit may be causing
a ground loop. Under no circumstances should you sever
the ground of the connected devices! 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.
6.5 The signal is totally distorted when you connect
an FX device (even when you dial in a clean sound):
•The effector's input is being overdriven. Decrease the
processor's input sensitivity by backing off its input
or gain knob.
6.6 The output signal level drops considerably when you
connect an effect device:
•The FX processor's output level is set to too low a level.
Turn it up.
