Do not remove covers: Operate the power unit with its covers correctly fitted. Refer any service work
to competent technical personnel only.
Power sources: Connect the power unit to a mains power only of the type described in this
User Guide and marked on the rear panel. Use the power cord with sealed
mains plug appropriate for your local mains supply as provided with the
console. If the provided plug does not fit into your outlet consult your service

Grounding: Do not defeat the grounding and polarisation means of the power cord plug.
Do not remove or tamper with the ground connection in the power cord.
WARNING: This equipment must be earthed.
Water and moisture: To reduce the risk of fire or electric shock do not expose the power unit or
console to rain or moisture or use it in damp or wet conditions. Do not place
containers of liquids on it which might spill into any openings.
Ventilation: Do not obstruct the ventilation slots or position the console or power unit
where the air flow required for ventilation is impeded. If the console is to be
operated in a flightcase ensure that it is constructed to allow adequate
ventilation.
Heat and vibration: Do not locate the power unit in a place subject to excessive heat or direct
sunlight as this could be a fire hazard. Locate the console and its power unit
away from any equipment which produces heat or causes excessive
vibration.
Servicing: Switch off the equipment and unplug the power cord immediately if it is
exposed to moisture, spilled liquid, objects fallen into the openings, the power
cord or plug become damaged, during lightening storms, or if smoke, odour
or noise is noticed. Refer servicing to qualified technical personnel only.

General Precautions
WIRE COLOUR
European USA/Canada
Damage : To prevent damage to the controls and cosmetics avoid placing heavy
objects on the control surface, scratching the surface with sharp objects, or
subjecting the console to rough handling and vibration.
Environment : Protect from excessive dirt, dust, heat and vibration when operating and
storing. Avoid tobacco ash, smoke, drinks spillage, and exposure to rain and
moisture. If the console becomes wet, switch off and remove mains power
immediately. Allow to dry out thoroughly before using again.
Radiation : To avoid induced noise and interference pickup do not operate the console
close to strong sources of electromagnetic radiation such as power supplies,
video monitors, lighting cables and dimmers.
Cleaning : Avoid the use of chemicals, abrasives or solvents. The control panel is best
cleaned with a soft brush and dry lint-free cloth. Stubborn marks can be
removed using a cloth dampened with isopropyl alcohol. Do not leave
marking tape stuck to the console for long periods of time as the adhesive
can degrade and leave a sticky residue. The faders, switches and
potentiometers are lubricated for life. The use of electrical lubricants on these
parts is not recommended. Refer to the power unit user guide for instructions
on cleaning its ventilation filters.
Transporting : The console should be transported in the original packing or purpose built
foam lined flightcase. Protect the control surface from damage during transit.
The console is a large and heavy item. To avoid injury ensure adequate man
power and precaution when lifting or moving the console.

How VCA Groups Work:
No audio passes through a VCA group. The channel signal routes direct to the
main mix. A VCA replaces the channel fader. The VCA is controlled by a
voltage from the channel fader and any VCA group master fader assigned to it.

ML3000 Key Features
The Allen & Heath ML3000 is a small footprint, affordable VCA equipped dual function live sound
console providing many of the features of its larger brothers the ML4000 and ML5000. It can be
quickly configured for front-of-house (FOH) or stage monitor mixing. As one console suitable for
both applications it is equally well suited to installation, rental and touring. It offers an IO capability
and feature set that satisfies the latest requirements of live sound engineering, in particular the
growing number of inputs and outputs for multi-speaker house and monitor systems, demands of
stereo in-ear monitoring, 3 speaker LCR imaging, advanced grouping and automation. The design
ensures on-the-road durability, a clear layout for easy walk up and go operation, and nocompromise audio performance.
Inputs and Outputs

The ML3000 console range is supplied with the
RPS11 power supply unit. A second RPS11 may
be connected through the optional RPSD2
combiner unit as a redundant (backup) supply.
Before connecting please read the IMPORTANT
SAFETY INSTRUCTIONS printed at the front of this
user guide and the warnings printed on the rear of
the power supply. Also read the user guide
provided with the power supply. Heed all
instructions regarding the installation and ventilation
requirements of the unit.
Connecting Mains Power
Check that the correct mains lead with moulded
plug suitable for your territory has been supplied
with your console. The RPS11 accepts mains
voltages 100, 120, 220, 230V AC by setting the
position of the rear panel fuse carrier.
WARNING: Make sure the power
supply voltage is correctly set to match your
local mains voltage. Refer to the power supply
user guide.
Make sure that the IEC mains plug is pressed fully
into the MAINS INPUT socket.
Connecting the DC Cable
Plug the cable into the power supply DC OUT
socket. First align the locating lugs, press the plug
into the socket, and screw on the locking ring to
hold it firmly in place. Plug and secure the other
end into the console DC POWER IN socket.
If you are using a second ‘redundant’ supply as a
backup then connect as described in the RPSD2
user guide.
Turning the Console On or Off
First check that the mains and DC leads are
correctly plugged in and secured. Turn on the
power supply using its front panel mains switch.
The console must be connected to the power
supply before turning it on.
To avoid loud pops in the speakers make sure that
the connected power amplifiers are turned off
before switching the console on or off.
WARNING: To avoid damage to the
speakers always switch the power amplifiers on
last and off first.
The console meters pulse briefly on power up. This
is normal.

Earthing
The connection to earth (ground) in an audio system is important for two reasons:
SAFETY - To protect the operator from high voltage shock, and
1.
2.
AUDIO PERFORMANCE - To minimise the effect of earth (ground) loops
which result in audible hum and buzz, and to shield the audio signals from interference.
For safety it is important that all equipment earths are connected to mains earth so that
exposed metal parts are prevented from carrying high voltage which can injure or even
kill the operator. It is recommended that the engineer check the continuity of the safety
earth from all points in the system including microphone bodies, guitar strings,
connector cases, equipment panels and so on.
The same earth is also used to shield audio cables from external interference such as
the hum fields associated with power transformers, lighting dimmer buzz, and computer
radiation. Problems arise when the signal sees more than one path to mains earth. An
earth loop results causing current to flow between the different earth paths. This
condition is usually detected as a mains frequency audible hum or buzz.
To ensure safe and trouble-free operation we recommend the following:
Use a clean mains outlet for the audio system. Keep the audio
equipment mains feed separate from that powering ‘dirty’ equipment such as air
conditioning and lighting systems, motors and vending machines.
Use star point earthing. It is best to install a ‘star point’ system where the
individual earths to the equipment racks and equipment areas are separately run from a
solid central reference earth point.
Have your mains system checked by a qualified electrician. If the
supply earthing is solid to start with you are less likely to experience problems.
Do not remove the earth connection from the console mains plug.
The console chassis is connected to mains earth through the power cable to ensure
your safety. Audio 0V is connected to the console chassis internally. If problems are
encountered with earth loops operate the audio ‘ground lift’ switch on the power supply
or connected equipment, or disconnect the cable screens at one end, usually at the
destination.
Avoid induced interference. To prevent interference pickup keep audio cables
away from mains power units, cables and distribution boards, motors, lighting and
computer cables and equipment, and any other heavy duty electrical equipment. Where
this cannot be avoided cross the audio and ‘dirty’ equipment cables at right angles to
minimise interference.
Use low impedance sources such as microphones and line level equipment
rated at 200 ohms or less to reduce susceptibility to interference. The console outputs
are designed to operate at very low impedance to minimise interference problems.
Use balanced connections where possible as these provide further
immunity by cancelling out interference that may be picked up on long cable runs. To
connect an unbalanced source to a balanced console input, link the cold input (XLR pin
3 or jack ring) to 0V earth (XLR pin 1 or jack sleeve) at the console. To connect a
balanced console output to an unbalanced destination, link the cold output to 0V earth at
the console.
Use good quality cables and connectors and check for correct wiring and
reliable solder joints. Allow sufficient cable loop to prevent damage through stretching.
If you are not sure ... Contact your service or local Allen & Heath agent for advice.
