6.0 TROUBLESHOOTING
1) The ATTAX 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.
2) The ATTAX 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 trip-
ped 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).
3) The footswitch does not switch channels:
- The front panel selector switch may be in the LEAD positi-
on. Set it to CLEAN (in this case, CLEAN = off).
- The footswitch is not connected to the ATTAX. Plug it into
the appropriate jack.
4) When accessed, the LINE OUT/LINE IN jacks cause
annoying hum.
- 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 sepa-
rated by routing the signal through a DI box.
5) 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.
- The LINE OUT signal is overloading the input of the FX
processor. Reduce the processor‘s input sensitivity ("INPUT"
or "GAIN").
6) You have connected an FX processor to the LINE OUT
jack of the ATTAX and the signal's volume level is way too
low.
- The FX processor's output level is set incorrectly. Turn it
up.
