OPERATION
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 screened connector is used.
ALWAYS use a balanced or floating low impedance microphone on long
microphone runs, terminating in a balanced input.
