INTRODUCTION
M-Line products are a set of self-powered systems for indoor and outdoor PA applications with small
to medium-sized audiences. Their acoustic design makes them perfect for events where sound quality
and de󽘀nition are the priority, while delivering high enough power for the intended attendance.
In addition, when great sound matters but space is scarce or transportation needs to be simple,
you will bene󽘀t from the solutions o󽗿ered by this sophisticated systems.
Compact, portable, powerful and easy-to-use, the M-Line is perfect for covering a wide range of
applications and productions. It is composed by the following products:
The M-Line is composed by the following products:
- M-F3A PRO: Updated high-performance line array units for the M-Line systems.
- M-F3A S12 PRO: Ground-stacked self-powered 12" subwoofers with user controllable DSP.
Referred to in this manual as "S12 PRO".
- M-F3A S15 PRO: Ground-stacked self-powered 15" subwoofers with user controllable DSP.
Referred to in this manual as "S15 PRO".
- M-F3A FS: Compact self-powered subwoofers for 󽘁own applications with user controllable DSP.
- M-F3A: 1st generation of the hornless line array units. Not available in Europe.
INTENDED USE
The M-Line consists of compact, active line array modules. The simple scalability of an M-Line system
allows for a maximum range of applications: from the professional sound boost for large events with
several thousand visitors, to small indoors and outdoors celebrations. When your aim is to have a
powerful, natural sound – but there is little space for your gear or the speakers need to be installed
discretely – that's when the M-Line comes to the fore.
Horns direct and guide the sound waves. But they also alter them – as anyone who has ever used both
hands to form a funnel around the mouth can con󽘀rm. The M-Line is based on an innovative, horn-free
design with dome tweeters in an array to provide absolutely natural, unaltered sound without sacri󽘀cing
the necessary sound pressure. The M-Line thus combines the advantages of both worlds: a wide dispersion
angle with robust sound pressure and crystal-clear, natural sound.
When used with the SE AUDIOTECHNIK® frame, systems of even 16 M-F3A or M-F3A PRO units can be
deployed to create short to medium-throw setups and cover wide ranges of audiences. The capabilities
of those systems can be extended to even the lowest frequencies by adding the S12 PRO, S15 PRO
and/or M-F3A FS subwoofers.
For example, 󽘁own systems with extended low-end can be realized with M-F3A FS subwoofers. Using
SE AUDIOTECHNIK® accessories, M-F3A or M-F3A PRO units can be combined with the S12 PRO and/or
S15 PRO subwoofers to deploy ground-stacked systems, with up to three S12 PRO subwoofers and four
M-F3A or M-F3A PRO speakers.
In addition, to broaden the capabilities of the system in the lowest frequencies, subwoofer arrays can
be implemented with S12 PRO or S15 PRO subwoofers. Used with the speci󽘀cally designed presets
and con󽘀gurations, these can be combined to create di󽗿erent patterns and control radiation in the
low frequencies.
In all the con󽘀gurations and thanks to an easy-to-use and precise rigging mechanism, you have control
over each unit's alignment, ensuring maximum coverage and long-throw capabilities.
Please, read thoroughly the Application Examples and Rigging and Installation sections for further
information about the setups, deployment and possibilities of the M-Line products.

M-F3A PRO LINE ARRAY UNITS
M-F3A PRO is an ultra-compact active line array system which o󽗿ers crystal-clear sound reproduction
with punchy mids and studio-quality highs, due to its hornless design.
The unique PA sound is achieved by incorporating 8 high-e󽘂ciency 2.8" neodymium mid-frequency
drivers, and 7 pieces of 1" direct radiation dome tweeters into each unit. All these drivers have been
designed for high e󽘂ciency and extended LF bandwidth. In result, it helps to lower the cut-o󽗿 frequency
in the low-mid band, which makes the vocals sound exceptionally rich and natural.
All drivers are mounted on an A4 paper-sized front surface. Each unit reaches up to 129 dB peak SPL and
weighs only 8.3 kg, including ampli󽘀cation and DSP. The M-F3A PRO's distinct sound is achieved by a
2-channel 600 W class-D power ampli󽘀er, delivering 2x300 W into the high- and mid-frequency drivers.
Two controls, the Level and the Line Unit selection, o󽗿er precise adjustment of the key system parameters,
such as attenuation and system voicing, depending on the unit count in the array.
Features
- Pristine acoustic reproduction
- Hornless design for natural, high-󽘀delity sound
- Ultra-compact size, weighing only 8.3 kg
- 120° horizontal coverage
- Built-in DSP and 600 W of class-D ampli󽘀cation
- Level and Line Units control
- Wide range of supported applications
- Available in black and white colors

6 Power Out. PowerCON® type-B mains power output to link power between several units in the line.
The recommended maximum quantity of units to be connected in series is 6 units for
200-240 VAC mains, and 3 for 100-120 VAC.
7 Indicator LEDs:
- Protect: Lights red if the ampli󽘀er has short-circuited or overheated – the device will be muted
automatically. Upon reaching standard conditions, the device reverts to normal operating mode
after a few seconds.
- Limit: Lights orange when the limiter starts working. If the limiter LED lights up permanently or for
longer periods, the gain level should be reduced. Failure to do so may result in a distorted sound.
- Signal: Lights green as soon as an audio signal is present. The input signal monitoring is performed
before the Main Level controller.
- Power: Lights green once the system is properly connected to the mains power and switched on.
8 Line Units. 8-position rotary switch to select the number of M-F3A PRO units in the array. On each
M-F3A PRO, specify the same quantity as units in the line. For example, select "5" on all devices in
an array of 5 units.
Acoustically, the bigger the line array, the greater the interference in the HF and from a lower
frequency. Choosing the right setting helps to improve the HF coupling and provides balanced
sound in all system sizes. Also, in combination with a dedicated multi-band limiter, it helps to
keep the same sound character on all SPL levels.
Since each position sets an equalization designed precisely for that speci󽘀c line length, this
feature must be used correctly. Setting values di󽗿erent than the units in the line, may reduce
the headroom of the system and alter its sound quality.
Finally, when using 8 or more units, specify "8+" on all. For more than 12 units, additional HF
compensation above 2 kHz may be required.
In M-F3A units, this knob is named "High Shelf" and follows the same logic as the "LINE UNITS" in
M-F3A PRO. Thus, it can be used to equalize the array according with the number of units it includes.
9 Line In. Balanced line-level input with female Neutrik® XLR-3 connector to connect input signal. It
allows input levels up to +20 dBu.
For an optimal signal-to-noise ratio, it is recommended to input signals with a level of at least
0 dBu.
10 Line Out. Balanced and bu󽗿ered line-level output with male Neutrik® XLR-3 connector to link other
M-F3A PRO speakers or other components like subwoofers to the system.
11 Fuse.
12 Power. Switch to turn the unit on and o󽗿.
To avoid clicks and pops, turn on your PA system last and turn it o󽗿 󽘀rst before other connected
devices. Additionally, after turning the unit o󽗿, wait for more than 󽘀ve seconds before turning it
on again.
S12 PRO AND S15 PRO SUBWOOFERS
The S12 PRO and S15 PRO are compact active subwoofers designed especially for the M-Line systems.
They are composed respectively by a single 12" and 15" driver in a vented box, powered by an 800 W
Class-D ampli󽘀er. Its e󽘂cient design and compact size guarantees 󽘁exible placement in all kinds of
environments. In addition, a two-point SE rigging system allows for safe and easy stacking.
These units contain a newly designed 800 W Class-D power ampli󽘀er and are equipped with 48 kHz/24 bit
DSP. By using the LCD screen and rotary encoder, users can easily control various system parameters such
as delay, EQ, 󽘀lters and more.
The built-in presets signi󽘀cantly reduce setup times for M-Line systems in various con󽘀gurations -
for example, simply select the preset for End-󽘀re or Cardioid arrays or a combination with a 󽘁ysub.
User-de󽘀ned custom-presets can also be stored.

M-F3A FS
The M-F3A FS is the 󽘁yable bass extension module for the popular M-F3A PRO line array systems. It utilizes
two specially designed 6" x 9" woofers that provide high sound pressure levels whilst presenting a sleek
and discreet design. This unit is twice as high as an M-F3A PRO. Thus, the modules complement each other
perfectly in every way.
The unit contains a newly designed 800 W Class-D power ampli󽘀er and is equipped with 48 kHz/24 bit DSP.
The LCD display and rotary encoder allow the user to select and control various system parameters such as
delay, EQ, 󽘀lters and other parameters.
Custom con󽘀gurations can then be saved as user presets. In addition, the built-in factory presets reduce
setup times for existing M-Line systems in various con󽘀gurations. In example, when 󽘁own with M-F3A
PRO, the unit can deliver rich and deep bass to manage applications where no space for ground subs is
available.
Improved rigging capabilities and the newly-designed extended bumper frame gives additional 󽘁exibility
to integrate this adaptable subwoofer into M-Line systems.

M-Line products use PowerCON® connectors for the mains power input and link. Figure 17 shows how to
plug-in and connect these wires.
It is recommended to use cables with at least 18 AWG conductor size. For long cable lengths, the maximum
conductor size is 14 AWG. Those wires must be assembled by a quali󽘀ed technician.
Conversely, M-Line products use XLR-3 connectors to input and loop audio signals. They follow the next
plug-in and con󽘀guration scheme:

LCD PLATE AMPLIFIER
The S12 PRO, S15 PRO and M-F3A FS subwoofers are equipped with a built-in 48 kHz/24 bit DSP
processor,that provides controlled signal processing and limiting. This DSP core is fed by dual-range
inputs to improve the SNR, and is easy to manipulate thanks to the rotary control encoder with push
button, and the 4x20 symbol alpha-numeric LCD screen.
This section details the features of the DSP 󽘀rmware, whose adjustable parameters and features include
5 EQ bands, delay, polarity and selection of low-pass 󽘀lters. Also, S12 PRO has an additional high-pass
󽘀lter, and S15 PRO the new directivity control function. In addition, a variety of factory presets is available
in both subwoofers, to easily setup di󽗿erent systems.
Some key cursors, symbols and considerations used throughout the menu structure are:
- The 󽘀rst line of each screen is the speci󽘀c name or title of the given screen.
- The cursor ">" marks the current point of action.
- When editing preset names, the cursor "←" indicates deleting function.
- The symbol "*" highlights the selection of a given preset or setting. It indicates also that the edition
of a given parameter is enabled.
- The symbol "L" indicates the lock state of the ampli󽘀er and thus, that the editing of any parameter is
not allowed. This symbol appears only when this is activated, and only in the Overview screen.
Figure 19 shows the di󽗿erent menus and functions of the DSP 󽘀rmware, structured in the following
subsections. Conversely, 󽘀gures 24 and 38 show respectively the functions included in the

OVERVIEW SCREEN
The Overview screen is the one shown by default on the ampli󽘀er LCD, during normal operation
(Figure 20). It details the next information:
- The 󽘀rst row shows the title of the screen and if applicable, the "L" letter in the top right-corner,
informing the lock state of the ampli󽘀er.
- The second row reads "IN:", followed by a numerical input level meter. The meter shows the current
input level value in dB FS, with minimum "-90" for low or no signal. The ">>>" symbols show the
signal strength relative to the clipping point at 0 dB FS. The readout is replaced with text "INPUT
CLIPPING!" if the signal reaches or exceeds 0 dB FS. In such case, the screen backlight is 󽘁ashing to
call the attention of the user.
- The third row reads "OUT:" followed by the output level meter. This meter shows current output
level relative to the maximum ampli󽘀er output. If the channel is muted, the level display meters are
replaced with the text "MUTED".
- The fourth row shows the gain reduction in dB "GR:" applied to the signal when the limiter threshold
is reached. When the value increases, new levels appear from right to left, according with the amount
of reduction applied.
From the Overview screen, the following options can be executed with the Master Control rotary encoder:
1. Turn left or right to adjust the output level (Figure 21). The output gain and the relative change in dB
are shown. The output level is always recalled and is not a󽗿ected by any reset function. A value of
0.0 dB refers to the nominal output gain of the subwoofer.
2. Turn just one step and push to quickly mute or unmute the ampli󽘀er output.
3. Push (without turning) to open the Active Preset Info screen and see both the active preset and the
delay currently de󽘀ned (Figure 22). Clicking "Back" will return to the Overview screen.
Letters "CA" after the name of the preset indicate that the cardioid directivity function is enabled.
