8. Service and
maintenance
Quantum™ amps do not require service of any kind. There are
however a few basic rules that, when followed, are sure to extend
the service life of your amp considerably:
• Make sure that all peripheral devices and cables are in a state
of good repair!
• Make sure that air circulates freely around your amp’s ventilation
ducts at all times.
• Absolutely avoid exposure to mechanical shocks, extreme heat,
dust and moisture.
• Pay particular attention to the specifications of peripheral
devices. Never connect devices with high output signal levels
(e.g. amps) to your amp’s input.
• Prior to plugging in your amp, always check that the AC power
source delivers the current the amp is designed to handle.
When in doubt about the local rating, ask the venue’s sound
technician or a stage hand.
• Refrain from ”do it yourself” repairs! Even the replacement of
internal fuses should be entrusted to an experienced technician.
• Use a soft dry cloth to clean the enclosure’s outer surfaces
and metal and acrylic glass surfaces. Never use alcohol or
other solvents!
• Ensure a correct impedance matching. Never fall below an
impedance of 2.7 ohm!
