IMPORTANT SAFETY INFORMATION
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!

1 GAIN TRIM
This control is used to adjust the input
gain and affects both the XLR and the
RCA inputs.. The input gain can be
adjusted by +/- 15dB. This allows a wide
rage of program sources to be set up with
optimum gain structure. With the gain trim
in the centre position, the boost/cut is set
to 0dB. See the block diagram on page
10 for details of the gain structure.
2 LEVEL
Controls the level of the input signal.
3 INPUT STATUS LEDS
Each input has an LED status indicator.
The LED is green when there is signal
present and red if the signal is
approaching clip. If the LED begins to light
red this would indicate the internal signal
level is 6dB before clip. Note that the front
panel level control is post status LED and
as such, the status LED is NOT affected
by the level control. If an input channel
is clipping use the gain control to adjust
the correct amount of input level.

1 CHANNEL 1 ROUTING
If channel 1 is being used as a priority
input it can be routed so that the master
volume does not affect channel 1.
The default factory setting is pre master
fader meaning the master volume affects
channel 1 in the mix. The jumper header
is located mid way above channel 1 pot.
Move the jumper to link the two pins
nearer channel 8 to set channel 1 to post
master fader.

BASIC SETUP & OPERATION
The inputs of the MX61 can accommodate a wide range of sources
including dynamic microphones, DVD and CD players. The output
may be used to drive power (booster) amplifiers, other mixers or
mixer amplifiers.
Each installation will require setting the appropriate relative mix of
levels between microphones and program. Because of the variation
in levels between the possible sources, the MX61 offers a number
of gain stage adjustments so you can set the correct levels for your
application. Also consider what the output is driving. . .
Setting up correct gain structure through the whole system is
important to achieve optimal results. The following step by step
procedure has been devised to assist during the setup process.
When the MX61 was shipped to you from the factory, it was set up in
a particular way. In the following procedure it is essential that you are
starting from these initial settings.
• Program Input Gain Controls – half (12 o’clock)
• XLR Mic/Line switch – MIC
• XLR Phantom power - on
STEP BY STEP SETUP
1 CONNECT THE SOURCES
First connect all the required sources to the appropriate input
connectors. If the source is a microphone, set the MIC/LINE
switches to the "MIC" position. If the source is an electret
or condenser microphone, set the phantom switch to the
"P/P on" position.
2 CONNECT THE OUTPUTS
Turn the amplifiers off. Connect the MX61 output to the amplifiers'
line level input. Check that the MX61 is on, and then turn on the
amplifiers. If the amplifiers have a level control, set them it to a
sensitivity of 0dBu. If in doubt, set it to maximum.
3 TEST THE INPUT LEVELS
For each source, try to achieve the highest signal level possible.
i.e. for a CD player, cassette deck or other music source, put on
the loudest anticipated program music or for a paging mic make a
‘loud’ page. During this signal condition, the input status LED should
light green and may occasionally turn red for a short period.
• Input Level Controls – off
• Output Level Control – off
If the status LED stays red (more than 10% of the time), you
should reduce the input gain trim. If the status LED never turns
red at all, you may wish to increase the input gain trim if required.
4 SET THE LEVELS
Turn the input levels up to 5. Turn up the output level until it is at
an appropriate level for the listening environment. You will now
have to adjust the relative levels of the inputs to achieve a good
balance. The aim of these adjustments is to have all level
controls at between 3 and 7. This may not be possible however.
A good rule of thumb is that input level controls should be higher
than the output level controls.
