IMPORTANT SAFETY INFORMATION

This operation manual contains important information regarding safety precautions, installation, performance, operation and
maintenance of your AMAV power amplifi er. You should familiarize yourself with the contents of this manual before
operating your amplifi er.

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 amplifi ers 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!

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 fl ow

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 amplifi ers or consoles to any

other voltage source, such as a battery, mains source, or power supply,

regardless of whether the amplifi er or console is turned on or off.

17. Do not run the output of any amplifi er channel back into another

channel’s input. Do not parallel- or series-connect an amplifi er output

with any other amplifi er 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 qualifi ed 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

12. Do not use the unit near stoves, heat registers, radiators, or other heat

producing devices.

THIS SAFETY INFORMATION IS OF A GENERAL NATURE AND MAY BE SUPERSEDED BY INSTRUCTIONS CONTAINED WITHIN THIS MANUAL

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.

channel at 4 ohms from an elegant, 2RU package. Both amplifi ers feature
front panel dual colour status LEDs, on board limiter, ground lift switch and
the option of bridged operation.

Add to this the AV2.2P and AV2.4P’s whisper quiet operation, achieved via
its convection cooled design and you have an elegant, high quality audio
amplifi er.

The AV2.2P and AV2.4P offers the power and the features demanded by any

Rev A: Mar 2007

This symbol is intended to alert the user to the presence
of uninsulated “dangerous voltage” within the products
enclosure that may be of suffi cient magnitude to constitute
a risk of electric shock to persons.

This symbol is intended to alert the user to the presence
of important operational and maintenance (servicing)
instructions in the literature accompanying the appliance.

To prevent electric shock do not use this (polarised) plug
with an extension cord, receptacle or other outlet unless
the blades can be fully inserted to prevent blade exposure.
To prevent electric shock, match wide blade of plug to wide
slot, fully insert.
