1 - INTRODUCTION AND APPLICATIONS
1.1 - INTRODUCTION TO SPOT2500T
The SPOT2500T active speaker system features a revolutionary new concept
in acoustic and electronic design characterized by painstaking attention in
terms of component selection, materials and production techniques.
The result is a product of absolutely contemporary, essential and rigorous
design, with great attention to detail.
All the system’s drivers, designed with great attention to every detail and
custom-built specically for this system, are equipped with the most
efcient and powerful motor assemblies available on the market today:
- woofers with neodymium magnets and long excursion, large diameter
voice coils
- controlled directivity wave-guide horns coupled to neodymium drivers
with very high magnetic ux.
Very high levels of performance, despite their remarkably small size and
low weight, thanks to power ampliers with digital technology controlled
by a dedicated Montarbo DSP processor.
The processor (56 bit, 180 MHz, 24 bit converters) takes care of the ltering,
equalization, delay, limiter and diagnostic functions, while optimizing the
system’s power and linearity. It utilizes an advanced algorithm for the
real-time control of both the power output and temperature (both internal
and external) of the amplier, thus increasing the system’s overall reliability.
5 presets are available, one of which may be customized by the user, thus
adapting the speaker’s acoustic response to the user’s personal taste.
A dedicated software program that was developed in our R&D laboratory
makes it possible to operate the speaker on a remote control basis by
means of a Personal Computer and our LD24 USB interface.
With a single LD24 USB interface it is possible to operate up to 10 speaker
systems by remote control.
The remote control allows: programming and storage of custom presets in
the PC; a 10 lter “fully parametric” equalizer; adjustment of the delay and
output level of each speaker system; monitoring of the power amplier’s
condition (temperature, protection circuits, limiters and thermal alarms);
a dedicated standby function which reduces power consumption when no
signal is present.
The control software makes these systems extremely exible.
In xed installations the ability to adjust the delay and equalizer make it
possible to align the sound system’s phase and frequency response
1.2 - SPOT2500T APPLICATIONS
The "quasi-tree-way" SPOT2500T system performs at extraordinarily high
levels whenever especially outstanding dynamics are required.
The typical application for this system is the coverage of large areas when
budgetary or technical reasons don’t allow for a suspended line-array
system. These systems were designed to simplify the task of assembling
clusters by simply placing multiple enclosures side-by-side when wider
horizontal dispersion is required, maintaining tonal coherence and
interference-free horizontal wave-front summing.
When it is not possible to place the speaker systems on the stage floor, the
SPOT 2500T may be placed at ground level and the full-range cabinet may
installed on top of the bass cabinet by means of a dedicated coupling bar.
It may also be used for stage-monitoring applications (in-fill system) and as
the 'resident' system in theatres and in live-performances venues.

2 - SYSTEM'S COMPONENTS
SPOT2500T is a 'quasi 3-way' active tri-amplied speaker system composed
of two modules: a full-range cabinet and a bass cabinet.
- The full-range cabinet SPOT2500T incorporates all the electronics needed
to process and power the whole system: three class-D amplifiers (with
switching power supplies) that can supply a total of 2500 Watts EIAJ
managed by the Montarbo DSP.
The system is equipped with:
- two 15” woofers, one of which is enclosed in the passive bass module.
Both feature a 4” voce coil and a powerful, shielded, neodymium
magnet. The magnet is front-mounted, allowing for improved cooling
under power-intensive conditions;
- one HF driver with a 1.4” throat and 3” voice coil, featuring a neodymium
magnet and titanium diaphragm, loaded by a high directivity wave-guide
horn. The horn has a very low cut-off frequency, resulting in improved
far-field intelligibility.

SPOT2500T - DSP CONTROLS
DSP CONTROLS
A - Green LED 'sig' (signal): it lights up when an input signal is detected.
B - Red LED 'clip': it lights up when a clipping (excess of signal level) is
detected in the input stage of the internal DSP. If this indicator ashes
frequently or is always on, reduce the input level, acting on the volume
control (6) or on the mixer's output gain control.
C - Yellow LED 'thw' (thermal warning): when lit, it indicates that the
temperature of the internal power ampliers is close to, or higher than,
the attention threshold: the internal microprocessor is analyzing the available energy. It is a normal behavior for this LED to ash even in absence
of input signal. For a correct operation, check periodically (monthly) the
rear panel's ventilation grills and verify that they are free of obstructions.
Also check that the speaker's temperature is not too high due to proximity
to heat sources or because subjected to direct radiation from the sun.
D - Red LED 'prot' (protection): this led indicates the intervention of the
protection circuit of the internal power ampliers. The reason may be an
excess in terms of temperature, of output current or a uctuation in mains
supply value (lighting strikes or brown outs). The LED comes on even if
the speaker has been muted by remote control, via the RAConLS software
program (refer to par. 5.3).
P1 - P2 - P3 - P4 - P0: these LEDs show the active Preset.
P1 - P2 - P3 - P4 are the factory (default) preset, P0 is the user preset.
The four LEDs P1 - P2 - P3 - P4 come on when the speaker has been muted
by remote control (refer to par. 5.3).-
UP - DOWN: these pushbuttons allow for preset selection.
For a description of the presets and how to load them refer to par. 4.2.
E - Green 'Sub 1' and 'Sub 2' LEDs: when on, they indicate that the SUB
OUT output is active and what type of sub-woofer drive signal has been
selected (refer to par. 4.2).

• 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 there can be
dangerous electrical potentials 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.
For details about mains power cable and ac link cable wiring,
refer to par. 3.2.
Connection to mixer
• If the mixer has XLR balanced outputs: use standard balanced XLR
connectors.
• If the mixer has XLR unbalanced outputs: in this case, unless 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):
it is possible to 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.
Connection of the full-range cabinet SPOT2500T to the bass cabinet
SPOT15B
Use the cable supplied with the system.
If longer cables are needed, they may be assembled following the wiring
instruction of par. 3.3.2.
Connection to a sub-woofer
• If the sub-woofer has an XLR balanced input (female): use a standard
balanced XLR cable (male-female).
• If the subwoofer has an XLR unbalanced input: make sure that the input is
unbalanced according to IEC 268 standard 1 = ground, 2 = hot, 3 = ground.
• If the sub-woofer has a JACK balanced input (stereo jack):
it is possible to use a stereo jack-XLR adapter, wired according to IEC 268
pin 1 = ground (sleeve), pin 2 = tip, pin 3 = ring.
• If the sub-woofer has a JACK unbalanced input (mono jack):
use suitable Jack-XLR female adapter unbalanced according to IEC 268
pin 1 = ground, pin 2 = tip, pin 3 = ground.
• Always use only heavy gauge, high quality SHIELDED cables (signal cables).
