4. Switch on the mixer or other source and make sure the output faders or master output
level controls are turned fully down.
5. Ensure that the mains voltage requirement of you model as indicated by the voltage label
(230v or 120v) matches your local AC mains supply. Connect the AC mains cable to the
Milan loudspeaker and turn on the mains switch. The green POWER LED will illuminate
to indicate that mains power is connected.
6. Increase the output level of the signal source to a normal operating level.
7. Slowly turn up the Milan loudspeaker’s level control(s) until a suitable volume level is
reached. The SIG/LIMIT LED illuminates green to indicate signal present and flashes red
when limiting. It is normal for the SIG/LIMIT LED to flash occasionally, but excessive or
prolonged illumination indicates that the input signal is too high or additional speakers
are required.

Self-Powered Loudspeakers
The Milan Mi0 self-powered loudspeaker is equipped with an integrated two-channel amplifier
module driving the high frequency and low frequency components independently, taking
consistent performance, convenience and ease of use to a new level. Milan eliminates the need for
separate amplifier racks and controllers, as well as the attendant cabling. This makes setting up at
gigs and obtaining a consistent sound in different venues a faster and simpler process.
The amplifiers are exactly matched to the known parameters of the loudspeaker components, and
are therefore able to produce the optimum power for the drivers. By placing the amplifiers in the
cabinet it is possible to keep the loudspeaker cables extremely short to eliminate resistive losses,
so effectively all the power from the amplifiers is transferred to the drivers.
The on-board electronics provides a mic and line input with two band EQ. Fast-acting limiters
allow you to achieve higher average sound pressure level, reduce the possibility of driver damage,
and help to ensure better long-term system reliability.
Using Milan Mi0 with Subwoofers
Improved bass response and higher overall sound pressure level can be achieved by adding sub-
bass loudspeakers to the Milan system. This also reduces mechanical stress on the Milan
loudspeaker’s low frequency driver, since most of the low frequency content in the signal is routed
to the subwoofer.
It is recommended that you connect the full range signal from the mixer first to the subwoofer(s),
and from there to the Milan Mi0.
Using Milan Mi0 as a Floor Monitor
Reduce the level of the BASS CONTROL when using Milan as a floor monitor, which will avoid any
low frequency boominess due to the proximity of the floor that can detract from clear and
intelligible monitor sound.
If you are using Milan as part of a larger multi-channel monitor system and where drums may be
part of the monitor mix, it is recommended that kick drum EQ is used sparingly and carefully.

Model Information
Milan Mi0 Self-Powered Loudspeaker
The Milan Mi0 is a self-powered sound reinforcement loudspeaker designed for many different
portable and permanently installed applications.
It consists of a custom 10” low frequency driver, matched
with a 1” high frequency compression driver on a 90°
horizontal x 60°vertical Converging Elliptical Waveguide
providing smooth and even coverage over a wide audience
area, together with a two channel amplifier module
providing microphone and line level input channels and
equalisation.
These high quality professional components are housed in
a lightweight, stylish and durable trapezoidal moulded
polypropylene cabinet that is instantly adaptable to front-
of-house or floor monitoring applications. The cabinet is
extensively ribbed and internally damped. This design
feature increases the cabinet’s rigidity and eliminates
internal reflections, which translates into better transient
response and improved bass reproduction. It also keeps
the weight of the cabinet as low as possible.
Mi0 is equipped with a dual angle pole mount socket which
allows it to be angled down for better coverage when used
with tripod stands or for mounting on top of bass cabinets. Lifting and carrying is made easy with
the provision of a comfortable scoop handle on the top of the cabinet.
The Mi0 cabinet provides M10 rigging points on the top and bottom for suspending horizontally or
vertically in permanent installs.

Connector wiring
The amplifier microphone and line inputs are designed to accept balanced (three conductor)
connections, and it is recommended that this method be used since it offers the best rejection of
noise, hum and radio interference, especially where long cable runs are involved. XLR connectors
should be wired pin 2 hot (positive), pin 3 cold (negative) and pin 1 ground, while the standard
wiring for 3-pole jack plug connectors is tip hot (positive), ring cold (negative) and sleeve ground
as shown below.

cold
ground

Balanced male XLR Balanced female XLR
Some signal sources such as keyboards, acoustic guitars with on-board electronics commonly
provide only an unbalanced output on a 2-pole jack connector. The Milan loudspeaker line input
can handle these connections without any rewiring since pin 3 (-ve) of the input is automatically
grounded by the jack plug.

If an unbalanced source is to be connected to an input channel via the XLR line input connector,
either 2-pole or 3-pole jack plugs can be used. In both cases pin 3 should be connected to pin 1
(ground) at the XLR as shown here.

1. Mains Connector and Fuseholder
Mains power is connected to the loudspeaker via a combination IEC connector and fuseholder.
Make sure that the Milan Mi0 loudspeaker is turned off before connecting mains power. Replace
the fuse only with the same type and rating.
2. Mains Switch
Rocker switch turns mains power on to the loudspeaker. Make sure the Mic Gain and Line Level
controls are fully off (MIN) and power up other external equipment such as a mixer before
switching on.
3. Ground Lift switch
Safely lifts the signal ground of the balanced audio inputs from the ground of the amplifier. Select
position as appropriate in order to minimise hum.
4. Microphone Input
Balanced female XLR connector for use with a variety of balanced and unbalanced dynamic
microphones. The mic input is not suitable for condenser microphones that require phantom
power. The input is balanced to avoid hum loops and RF interference, and is wired pin 2 hot, pin 3
cold.

5. Line Level Input
Combination jack/XLR connector that will accept a wide range of balanced and unbalanced line
level sources such as keyboards, acoustic guitars with on-board electronics and other line level
sources such as CD players and DJ mixers.
6. Mix Out
An unbalanced line level output on a male XLR that connects to additional powered Milan
loudspeakers. This output contains a mix of all connected sources and is post-EQ. Note that
adjusting the equalisation will similarly affect any additional Milan loudspeakers connected from
this output.
7. Line Level Control
Rotary level control which attenuates the input signal level of the connected instrument / line
source.
8. Treble Control and 9. Bass control
The bass control provides 6dB of boost or cut at 90H with a shelving curve shape, and the treble
control provides 6dB of boost or cut at 8kHz with a shelving curve shape. Always use equalisation
sparingly, aiming to cut rather than boost especially when the loudspeaker is used near
boundaries such as walls or floors.
10. Mic Gain Control
Rotary level control which attenuates the input signal level of the connected microphone. Allows
the mic signal to be optimised for the first and subsequent loudspeakers connected to the MIX
OUT connector.
11. Limit Indicator
Illuminates green to indicate the presence of signal at the amplifier input. Illuminates red when the
amplifier’s output is limited. Frequent and/or continuous lighting of the limit LED indicates
overdriving. If this occurs reduce the input level to the loudspeaker or enlarge your system with
additional loudspeakers.
12. Power Indicator
Illuminates green to indicate that mains power is connected and powered up.

Small duo setup using the integrated mixer and Mix Out
The built in two channel mixer allows the simultaneous use of a low impedance dynamic
microphone and a line level source. The line level source could be an acoustic instrument such as
a guitar with either passive or active on-board electrics, a keyboard, or MP3 player. Connect
dynamic microphones directly to the mic input connector, and adjust the volume level. Connect
line sources to the combo jack/XLR connector and adjust the volume control. Use the MIX OUT
function to daisy-chain to additional Milan loudspeakers.

Stereo PA with an external mixer and subwoofers
In this example, sub frequencies are routed to separate subwoofers in order to gain extended
frequency response and higher overall sound level. Connect the mixer output first to the
subwoofers and then loop up to the Milan loudspeakers. Connect the outputs of the subwoofers to
the Mi0 line inputs using either balanced XLR cables, or balanced or unbalanced jack cables. The
tone controls on both cabinets should be set to the same positions, nominally flat to begin with.
Ensure that the mixer outputs are not clipping, and then adjust both loudspeakers’ level controls
to the desired loudness.

Loudspeaker Placement
In order to avoid the possibility of feedback locate the loudspeakers in front of your microphones
and do not point microphones directly at the front of a loudspeaker.
When using speaker stands, try to raise the loudspeakers as high as practically possible (at least
higher than the heads of the audience) since people are very good absorbers of sound, especially
at high frequencies. You also have the option to point them down using
the alternate angle provided for by the built-in dual angle pole holder.
Doing this will improve the coverage for
both near and far audience members.
SAFETY PRECAUTIONS: make sure that
any speaker stands you use are capable of
taking the weight of the loudspeaker, and
that stands are placed on a flat, level and
stable surface. Make sure that the legs do
not present a trip hazard. Take care when
lifting the speakers on to the stand; ask
someone else to help you if needed.
The same applies to using Milan
loudspeakers mounted on straight poles on
top of bass cabinets or subwoofers.
Adjustable height poles or stands allow you
to fine tune the height of the loudspeakers
to suit your venue.
Do not place your loudspeakers too close to
turntables as this may induce rumble or
low frequency feedback from the tone
arms. Isolate turntables on shock mounts.
Use equalisation sparingly. Start with the
bass and treble controls at their neutral
position (no boost or cut). Cut a little bass
to tame any boomy frequencies in the
room, and add a little treble to help vocal
intelligibility.
Consider adding subwoofers and/or further loudspeakers if the overall sound level or low
frequency response is not enough for the room.

Installing the Milan loudspeaker
Using the M10 rigging points
The Milan loudspeaker can be permanently installed in a venue, suspended
from eyebolts fitted to the internal M10 rigging points on the top and bottom
of the cabinet. Three possible orientations are available: vertically upright, or
upside down to position the high frequency driver closer to the audience, or
sideways if required.
Insert M10 load-rated shoulder eyebolts into the
threaded rigging points and tighten. The front
rigging points should take the majority of the load
while the rear rigging point should be used for
angling the cabinet downwards only.
When installing the
cabinet sideways, pick
up from either of the
two front eyebolt
pairs, and bridle the
two rear eyebolt points to provide a single pull-
back for adjusting the downward angle.
Wall Mounting
The Milan loudspeaker can be conveniently wall mounted using the PB-55 pole mount wall
bracket, which simply locates into the pole mount socket in the bottom of the cabinet.
Mount the bracket to the wall using suitable fixings, and locate the loudspeaker onto the pole
mount bracket. Rotate and angle the loudspeaker to optimise coverage and tighten the locking
mechanism to stop the loudspeaker from being inadvertently removed.
