WARP X - MANUAL
HOW DO YOU EXTEND THE SERVICE LIFE OF THE
WARP X™'S TUBES?
• Never operate the WARP X™ without connecting a
load (loudspeaker)! Always use high-quality, heavy-
duty speaker cables that won't crimp or snap...
• Use the STANDBY switch! Warming tubes up unneces-
sarily wears them out that much quicker. Make a habit
of cutting anode voltage via the STANDBY function and
you'll enjoy many more hours of operation.
• Avoid exposing the amp to vibrations, especially when
it's powered up. Switch the amp off a good while
before moving it, allowing plenty of time for the tubes
to cool off completely.
• Ensure plenty of air can circulate around the amp's
ventilation slots at all times – your WARP X™'s life
depends on it.
• Definitely avoid exposure to extreme heat, dust and
particularly moisture.
• Be very careful about the kind of peripheral devices
you connect to your amp and always check out their
specs before you plug them in. Never connect speaker
cabinets with an impedance (ohm) rating lower than
the WARP X™ is designed to handle.
• Never connect devices with high output signal levels
(e.g. power amps) to the WARP X™'s input.
• Ensure 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 performing DIY repairs! To be on the
safe side, you should also have a qualified technician
replace internal fuses.
