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