General Installation
•ALWAYS ensure that the equipment is properly earthed (grounded). Operating
without an earth is dangerous and may cause high levels of audible hum from the
speaker outputs.
•NEVER remove the top cover of the amplifier or make an internal adjustment with the
ac mains supply connected. All internal servicing should be performed by a competent
and qualified engineer.
•DO NOT expose the unit to rain or moisture. If any fluids or foreign objects should
enter the unit, disconnect the power plug immediately.
•DO NOT site the equipment in locations exposed to direct sunlight, near heaters or
other heat sources. Avoid locations with high humidity or dust levels.
•DO NOT obstruct the ventilation slots in the amplifier case and allow adequate
ventilation. (Ensure that a 1U ventilation panel is fitted above the unit if the amplifier is
rack-mounted.)
•DO NOT run microphone cables near mains, data, telephone or 100V lines.
•AVOID jointing the microphone cables if possible. If this is unavoidable, make sure a
good screen connector is used.
•ALWAYS use a balanced or floating low impedance microphone on long microphone
runs, terminating in a balanced input.
