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.
