15. TROUBLESHOOTING

F1) The zenTera ® won't power up when you
switch it on:
• It's not getting 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 blows,
be sure to talk to your local Hughes & Kettner
dealer.
F2) The zenTera ® is cabled up and connected
properly, but no sound is audible.
• One or more of the volume knobs or the master
knob is/are turned all the way down. Dial in
higher settings.
• The internal speakers are not connected. Plug
them in.
• The zenTera ® is in TUNER mode, which means
that it is muted. Quit TUNER mode by tapping
the TUNER button.
• A shorted external speaker cable caused one of
the internal fuses to blow. Have a qualified
technician change the fuse (ensure the
replacement fuse bears the proper rating).
• The volume pedal of the connected Z-Board is
set to the minimum position. Floor the pedal.
F3) The zenTera ® will not respond to the
Z-Board or footswitch.
• The connector of the Z-Board or footswitch is not
plugged in correctly or at all. Plug it into the
zenTera ® , ensuring that it is seated firmly.
F4) The sound is totally distorted when you
activate a connected effects device.
• The input of the effect device is being over-
driven. If it is equipped with a level meter or
other level indicator, check the signal level and
back off the signal processor's input sensitivity
(via a knob labeled "Input" or "Gain").

F5) The signal level drops considerably when
you connect an external effects device.
• The effect device's output level is too low. Turn
up the level on the signal processor.
F6) A connected MIDI controller is not
®
getting operating voltage via the
phantom power feed of the MIDI IN port:
• The phantom power fuse tripped. Replace the
blown fuse making sure that the replacement
has the same specs as the original fuse.
F7) System Initialize:
• You can perform a factory reset on the zenTera
by pressing and holding PRESET and STORE while
powering up. SYSTEM INIT appears in the display
for about eight seconds. Following successful
initialization, the zenTera ® has the following
status: The System menu is reset to the factory
setting.
Note: The head is reset to 4x 12" if it was set to
another configuration. P 1 – P 28 are copied to
1 – 28. 29 - 100 remain unchanged.
Caution: All your user presets and system settings
are deleted or reset to the original values. Then
you can upload your archived sounds to the
zenTera ® using the SoundDiver™ software.
