INSTALLATION AND OPERATION MANUAL

IMPORTANT SAFETY INFORMATION
1. Save the carton and packing material even if the equipment has
arrived in good condition. Should you ever need to ship the unit, use
only the original factory packing.
2. Read all documentation before operating your equipment. Retain
all documentation for future reference.
3. Follow all instructions printed on unit chassis for proper operation.
4. Do not spill water or other liquids into or on the unit, or operate
the unit while standing in liquid.
5. Make sure power outlets conform to the power requirements listed
on the back of the unit.
6. Do not use the unit if the electrical power cord is frayed or broken.
The power supply cords should be routed so that they are not likely
to be walked on or pinched by items placed upon or against them,
paying particular attention to cords and plugs, convenience
receptacles, and the point where they exit from the appliance.
7. Always operate the unit with the AC ground wire connected to the
electrical system ground. Precautions should be taken so that the
means of grounding of a piece of equipment is not defeated.
8. Mains voltage must be correct and the same as that printed on the
rear of the unit. Damage caused by connection to improper AC voltage
is not covered by any warranty.
9. Have gain controls on amplifiers turned down during power-up
to prevent speaker damage if there are high signal levels at the inputs.
10 Power down & disconnect units from mains voltage before making
connections.
11. Never hold a power switch in the “ON” position if it won’t stay
there itself!
12. Do not use the unit near stoves, heat registers, radiators, or other heat
producing devices.
13. Do not block fan intake or exhaust ports. Do not operate equipment
on a surface or in an environment which may impede the normal flow
of air around the unit, such as a bed, rug, weathersheet, carpet,
or completely enclosed rack. If the unit is used in an extremely dusty
or smoky environment, the unit should be periodically “blown free”
of foreign matter.
14. Do not remove the cover. Removing the cover will expose you
to potentially dangerous voltages. There are no user serviceable
parts inside.
15. Do not drive the inputs with a signal level greater than that required
to drive equipment to full output.
16. Do not connect the inputs / outputs of amplifiers or consoles to any
other voltage source, such as a battery, mains source, or power supply,
regardless of whether the amplifier or console is turned on or off.
17. Do not run the output of any amplifier channel back into another
channel’s input. Do not parallel- or series-connect an amplifier output
with any other amplifier output. Australian Monitor Inc is not
responsible for damage to loudspeakers for any reason.
18. Do not ground any red (“hot”) terminal. Never connect a “hot” (red)
output to ground or to another “hot” (red) output!
19. Non-use periods. The power cord of equipment should be unplugged
from the outlet when left unused for a long period of time.
20. Service Information Equipment should be serviced by qualified service
personnel when:
A. The power supply cord or the plug has been damaged.
B. Objects have fallen, or liquid has been spilled into the equipment
C. The equipment has been exposed to rain
D. The equipment does not appear to operate normally, or exhibits a marked
change in performance
E. The equipment has been dropped, or the enclosure damaged.
