ZENAMP-MANUAL
5.0 MAINTENANCE AND CARE
The zenAmp does not require service of any type. There are
however a few basic rules that will extend the service life of your
amp enormously:
• Make sure all peripheral devices, cords and cables are in a
state of good repair! Poor-quality cables will cause hum and
undesirable noise.
• Ensure plenty of air can circulate around your amp's ventilation
ducts at all times.
• Definitely avoid exposure to mechanical shocks and extreme
heat, dust and particularly moisture.
• Be picky about the kind of peripheral devices you connect
to your amp and always check out their specs before you
plug them in. Under no circumstances should you connect
devices with high output signal levels (e.g. power amps) to
your amp's input.
• Be sure the AC power source delivers the current that your amp
is designed to handle before you plug it in. When in doubt
about the local rating, ask the venue's sound technician or
a stage hand.
• Refrain from DIY repairs! To be on the safe side, you should also
have a qualified technician replace internal fuses.
6.0 TROUBLESHOOTING
E1) The zenAmp 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.
E2) The zenAmp is cabled up and connected properly, but no
sound is audible.
• One or more of the volume or master knobs is/are turned all the
way down. Dial in higher settings.
• The volume pedal of the connected Z-Board is set to the
minimum position. Floor the pedal.
E3) The zenAmp 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 zenAmp, ensuring that it is
seated firmly.
E4) The sound is totally distorted when you activate a connected
effects device.
• The input of the effect device is being overdriven. 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").
E5) The signal level drops considerably when you connect an
external effects device,
• The effect device is sending the signal back at too low a level.
Turn up the signal processor's output level.
