BXSERIES
SELF-POWERED SUBWOOFERS
Introduction
The BX series includes four models of active subwoofers:
BX182A (dual 18” woofer), BX152A (dual 15” woofer),
BX181A (single 18” woofer) and BX151A (single 15” woofer)
Each of them is equipped with custom designed woofers
incorporating innovative manufacturing technologies that
result in greater power handling with lower moving coil
temperature, thus guaranteeing large reliability margins.
The on-board electronics, the fruit of cutting-edge engineering, include self-diagnostics circuitry and a sophisticated
speaker protection circuit that monitor the operation of the
internal power amplifiers in real time. The latter, developed
in the Montarbo R&D labs, is a Dynamic EQ Controller
(D.E.Co.), that integrates the functions of a dynamic equalizer
with those of a compressor/limiter. The operating thresholds
are dynamically set, in real time, by the amplifier’s available
power reserve.
The D.E.Co. eliminates power amplifier clipping, even with
very high input signals, and the dynamic equalizer controls
the frequency response, thus guaranteeing a full and
controlled bass response, without compromising the available
dynamic range.
An internal stereo electronic cross-over (that may be bypassed
for wide-band use) drives the internal low frequency power
amplifiers and the external active loudspeakers (or external
power amplifiers) for the middle and high frequency range.
The internal power amplifiers (MosFet, class AB) were
designed around an innovative driver stage that guarantees
the lowest possible distortion, while providing excellent
dynamic and tonal performance.

speaker systems, connected to the stereo output (2), to receive a
full-range signal or the upper audio range only. In both conditions
the signal is affected by the 'X-Over' volume control (7).
☞ Button up (crossover off) = 'flat' mode: the output signal is
'full bandwidth'.
☞ Button pushed (crossover on) = 'x-over mode': 100Hz÷20kHz

X-OVER: 2 unbalanced XLR male sockets for the stereo output.
3 IN: 2 balanced inputs, fitted with Neutrik Combo® connectors
which accept both XLR and jack plugs (connection to the mixer).
Note: by using a mono jack connector the signal is automatically
unbalanced.
4 LINK: 2 balanced XLR male sockets ('link') for parallel

5 LIMITER: LED indicator. The LED lights up when the signal level
is approaching the maximum (clipping) allowable level. If the LED is
continuously lit, you must reduce the output level of the mixer or
rotate the input level control to a lower (counter clockwise) setting.

7 X-OVER VOL.: this allows you to set the volume of the speaker
systems connected to the X-OVER output (2).
This volume control is particularly useful to adapt the gain of the
satellite speaker system to the gain of the subwoofer according to
the different possible configurations (mono, stereo).
8 PHASE REVERSE: by means of this switch the absolute
phase of the subwoofer may be reversed, allowing for the use
of satellite loudspeakers with a non-standard phasing, or for
multi-subwoofer installation, thereby avoiding possible phase
cancellations.

Use only the factory supplied mains cable or a suitable cable with
a ground connection and marked with the safety approvals valid in
the country of use.
When installing make sure that it is easy to get to this connector
and to the mains plug.
11 The output stages are cooled by a forced air heat exchanger,
equipped with a temperature-controlled, low-noise fan.
Note: in order to reduce noise and dust build-up, the thermostatically
controlled fan is not activated unless the amplifier heats up to a pre-set
level, and it turns off automatically when the temperature drops back
down below this level.

BXSERIES
SELF-POWERED SUBWOOFERS
Connection examples
The very low frequency range reproduced by the subwoofers of the
BX Series is essentially omnidirectional allowing easy installation of
the enclosure. In most cases the subwoofer can be placed near to
the satellite loudspeaker system, but when space or set up reason
dictate it, the subwoofer can be positioned at some distance from
the satellite system (e.g.: under the stage floor).
You must always consider that the extended low frequency range
increases the risk of acoustic feedback, with undesired 'howls' and
reduced clarity. It is thus essential to place the subwoofer on a rigid
structure, that does not transmit vibrations to the microphones.
Some connection examples - among the most common possible
configurations - are described below and also illustrated on pages
24 and 25 of this manual.
☛ Always make sure to use only heavy gauge, high quality
shielded cables.
Example A: 1 BX subwoofer + 2 self-powered loudspeakers
The complex connections that other systems usually require for
this configuration are made extremely simple with the subwoofers
of the BX Series thanks to the L/R outputs of the built-in stereo
electronic cross-over.
Note: It is advisable to place the subwoofer in the center, between the
two self-powered loudspeakers
mixer L / R outputs ➟ subwoofer L / R inputs
subwoofer 'x-over' L / R outputs ➟ inputs of the two self-powered
loudspeakers
• If the self-powered loudspeakers have the same input sensitivity as the subwoofer (which is 0dB) set the control 'X-OVER VOL.'
(7) to its maximum position.
☛ See connection example A on page 24
• Connect the L and R outputs of the mixer to the L and R inputs
(3) of the subwoofer.
• Connect the X-OVER L and R outputs (2) of the subwoofer to
the inputs of the 2 self-powered loudspeakers. This set-up allows
them to benefit from the increase in dynamic range provided by
the electronic crossover of the subwoofer.
• Make sure the X-Over / Flat button (1) is pushed.
• The output levels of the two self-powered loudspeakers are not
affected by the 'VOLUME' control (6) of the subwoofer.
First set the volume controls of the self-powered loudspeakers to
their maximum position, then adjust the control 'X-OVER VOL.' (7)
to obtain the desired tonal balance.
Example B: 2 BX subwoofers + 2 self-powered loudspeakers
• Connect the L and R outputs of the mixer to the 'R' inputs
(3) of the two subwoofers.
• Connect the X-OVER 'R' outputs (2) of the two subwoofers
to the inputs of the two self-powered loudspeakers.
• Make sure the X-Over / Flat button (1) is pushed on each
subwoofer.
• The output levels of the self-powered loudspeakers are not
affected by the 'VOLUME' control (6) of the subwoofers.
First set the volume controls of the self-powered loudspeakers to
their maximum position, then adjust the control 'X-OVER VOL.' (7)
to obtain the desired tonal balance.
Example C: 1 BX subwoofer + 2 self-powered loudspeakers
This is a more complex configuration which enables selective
enhancement of the low-frequencies (for example, only on drums
and keyboards, not on voices or brasses).
Note: It is advisable to place the subwoofer in the center, between the
two self-powered loudspeakers
mixer 'AUX' output ➟ subwoofer 'R' input
mixer L / R outputs ➟ inputs of the two self-powered
loudspeakers
☛ See connection example C on page 25
• Connect the AUXILIARY output of the mixer to the 'R' input (3)
of the subwoofer.
• Connect the L and R outputs of the mixer to the inputs of the
two self-powered loudspeakers respectively.
• This type of set-up allows you to use the subwoofer to extend
the low frequency response of only those instruments that really
need it (e.g. drum machines, bass, keyboards).
These instruments are selected by means of the AUX send controls
on the corresponding channels.
The subwoofer's volume control and the mixer's AUX output level
control adjust only the very low frequencies.
Parallel connection of two or more systems
mixer L / R outputs ➟ L / R inputs of the first subwoofer
L / R outputs of the first subwoofer ➟ L / R inputs of the second
subwoofer
• Connect the L and R outputs of the mixer to the L and R inputs
(3) of the subwoofer.
• Connect the 'LINK' L and R outputs (4) of the subwoofer to the
L and R inputs (3) of the second subwoofer.
☛ See connection example on page 25
This is the most typical configuration where each subwoofer drives
one self-powered loudspeaker.
mixer L / R outputs ➟ 'R' inputs of the two subwoofers
x-over 'R' outputs of the two subwoofers ➟ inputs of the two
self-powered loudspeakers.
☛ See connection example B on page 24
• If the self-powered loudspeakers have the same input
sensitivity as the subwoofer (which is 0dB) set the control
'X-OVER VOL.' (7) to its center position.

Connection examples
Connection to the mixer
• Always use only heavy gauge, high quality SHIELDED cables
(signal cables).
• Always make sure that the mixer, the subwoofer and any other
powered enclosure are switched off before connecting them.
This is to avoid annoying noises and signal peaks, which can also be
dangerous for the enclosures themselves.
If the mixer has XLR balanced outputs: use standard balanced
XLR connectors.
If the mixer has XLR unbalanced outputs: unless you are using a
Montarbo mixer, make sure that the XLR outputs on the mixer are
unbalanced to IEC 268 standard, 1 = GND, 2 = HOT, 3 = GND.
If the mixer has JACK balanced outputs (stereo jacks):
use stereo jack-XLR adapters, wired according to IEC 268,
pin 1 = ground (sleeve), pin 2 = tip, pin 3 = ring.
If the mixer has JACK unbalanced outputs (mono jacks):
use suitable Jack-XLR male adapters unbalanced according to IEC
268, pin 1 = ground, pin 2 = tip, pin 3 = ground.
☛ See 'connectors' at page 23.
Note:
In our configuration examples we are using the L and R master
outputs of the mixer, but if they are not available (as, for example,
in a powered mixer) the insert sockets on main L/R outputs can
be used to the same purposes.
Take the signal at the insert sockets by means of a stereo jack plug,
in which you have shorted the RING and the TIP and send it to the
inputs of the subwoofer by means of an XLR or a jack (see picture).

Product care and maintenance
• Always keep air vents unobstructed so air can circulate freely.
Otherwise, electronic components may overheat and suffer
damages. To ensure proper ventilation, place the subwoofer a
sufficient distance away from walls and make sure it isn’t covered
by curtains etc... This is vital to keep the power amp cool.
• Never expose the enclosures to direct sunlight, excessive
vibrations or mechanical shocks.
• Never place burning candles or other sources of open flame on
top of the device. Do not expose the enclosures to heat sources
(lamps, lights, high power light sources, radiators or other heat
producing equipment).
• Avoid operating and storing the system in damp or dusty
places: this may lead to malfunctions and premature degrading
of specifications.
• Avoid using the system close to strong sources of electromagnetic
interference (e.g. video monitors, high power electrical cabling).
This may lead to degradation of audio quality.
• When setting up the system outdoors, be sure to protect it
against rain.
• Care should be taken to prevent small objects or liquids from
falling or spilling into the enclosure. In public events don't allow
musicians, technicians or anyone else, put glasses, cups, ashtrays or
cigarettes on the enclosures.
• Always leave the protective grid mounted on the enclosures.
• Use a soft brush or a jet of air to clean the enclosure. Do not use
alcohol, solvents or detergents.
• Take care of the connecting cables. Make sure that they are not
damaged, knotted or twisted.
• Do not force connectors and controls.
• As long as it is plugged in, dangerous electrical potentials may
be present inside the device, so, before undertaking any sort of
maintenance work etc., always make sure it has been unplugged
from the mains socket.
Power supply connection
• Make sure the mains power switch is off ('0') before starting any
connection.
• Check that mains voltage corresponds to the voltage indicated
on the panel.
Phase
In any sound reinforcement system the correct phase is of
fundamental importance.
Two speakers that are carrying the same musical program interact
with one another and this can cause destructive interference.
This means that the sound waves, emitted by two speakers,
reaching a listener's position (or a point in the auditorium) with
different phase (two different points of the sound wave) may
combine in the 'wrong way' and, instead of summing themselves
and generating a sound wave of larger amplitude (a sound
pressure 'louder' than that produced by a single speaker), will
generate a lower sound pressure. In other words, the two sound
waves will subtract instead of summing.
The worst condition is when the phase of the two signal is
opposite (a phase shift of 180°: out of phase): this results in a
mutual cancellation of the sound waves. In fact, if the first wave
reaches the listener with the maximum value (positive pressure )
and the second with the minimum (negative pressure), the
resulting sound wave sum will be of zero value (or at lest a very
low value, lower than that produced by a single speaker).
Among the possible causes of these phase shifts are the listener's
position in respect to the speakers, the type of acoustic loading
used in the speakers, the acoustics of the location, the
characteristics of the cross-over and the electronic processors.
The phase reversal button located in the BX series control panel
(8, page 14) is meant to avoid the most extreme condition
(out of phase: 180° phase shift), and to limit, in most cases,
the phase cancellations described above.
This solution is used primarily in simple systems that do not include
a separate PA speaker processor (which, in more complex and
sophisticated systems, will take care of the phase alignment by
adjusting the time delay between the speakers used in different
audio ranges).
The most 'classical' application is in the relative phase
correction of a sub woofer and a satellite speaker combination.
In the cross-over region (100/120 Hz in Montarbo systems) the
physical location of subwoofer and satellites (and other factors
described above) may cause a phase shift between the sound
waves generated by the speakers, and this will result in a 'hole'
in acoustic response.
In this case, the phase inversion of the subwoofer (by pushing
button 8, page 14) will minimize this effect.
It is mandatory to check that the phase is set at the same value
on every subwoofer installed.
A phase inversion in one or more of them (due to the improper
setting of the control), relative to the others, will result in the
quasi-complete cancellation of the sound produced by them.
In standard installations all the subwoofer must have the same
phase setting (all set to 0° or all set to 180°).
• Use only the factory supplied mains cable or, if a different plug
style is needed, a suitable cable with a ground connection and
marked with the safety approvals valid in the country of use.
• Leave enough room to get to the mains power socket and the
mains connector on the back panel. As long as it is plugged in,
dangerous electrical potentials may be present inside the device,
even when the mains switch is in the '0' (off) position and the
power indicator is off so, before undertaking any sort of
maintenance work etc., always make sure it has been unplugged
from the mains socket.

Input sensitivity and clipping.
How to avoid clipping
Every amplified speaker system is characterized by a value of input
sensitivity. The sensitivity is defined as the value of the amplifier's
input signal that will result in maximum power output.
An increase in input signal over that threshold will result, not in
increased power, but in a distortion phenomenon called 'clipping'
(output stage saturation).
In this condition, the speaker will operate improperly.
The diaphragm will exceed it's excursion limits, and the voice coil
will overheat beyond it's thermal limits, resulting in overheating
and premature failure.
The active processors will help in avoiding clipping, by reducing the
amplifier gain and thus the input sensitivity, but these protections
may be overridden in very extreme conditions.
What the active processor cannot modify is a signal that is distorted
before getting to the active speaker's input.
The simplest way to avoid clipping is to check each level in the
signal's chain. Start from each input channel of the mixer and
adjust the gain control and the equalizer controls so that the PFL
meter will never (or only occasionally) indicate more than 0dBu.
In simpler mixers, check that the 'clip' or 'peak' indicator is always
off, or blinks only occasionally.
If these levels are exceeded, reduce the mixer channel's input gain.
Once the desired mix is obtained, adjust the output level so that it
never exceeds the active speaker's or the power amplifier's input
sensitivity, as displayed on the master output VU-meter.
In models BX151A, BX152A, BX181A and BX182A the input
sensitivity is 0dBu.
The effects of this type of signal are the same as described above.
ONLY FOR MODEL BX182A :

Wiring of the power cable for the PowerCon
connector (supplied with the unit).
®
8 mm
Strip the cable for 20 mm of length and strip each wire for 8 mm of
length. We suggest to use a power cable with 1,5 ÷ 2 mm2 section
wires (the insert terminals can however support a cable with wires
up to a section of 4 mm2/12AWG).
Insert the power cable into the bushing and into the chuck (white
chuck for a cable diameter of 5 ÷ 11 mm; black chuck for a cable
diameter of 9.50 ÷ 15 mm). Fit a ferrule at the end of each wire
and connect wires on the insert.
The wire ends can be clamped in or soldered to the terminal.
Always paying attention to the symbols shown on the connector:
L (Live - corresponding to the brown wire),
N (Neutral - corresponding to the light blue wire) and (Ground - corresponding to the yellow and green wire).
