UNCOMPROMISING ENGINEERING,
ATTENTION TO DETAIL
NEXO S.A.
Now in its fourth decade, NEXO’s company mission is
to provide wide-ranging solutions that enhance the
science, art and commerce of sound reinforcement.
Founded by Michael Johnson, NEXO’s Managing
Director, and Chairman/R&D Director Eric Vincenot,
NEXO became a publicly traded company in May
2001. NEXO shares are listed on the Marche Libre of
the Paris Bourse (SICOVAM 4441).
The added access to capital markets
gained by this public offering strengthened NEXO’s
ability to pursue aggressively genuine audio
innovations. The first of these advanced audio
design options is the widely heralded GEO Tangent
technology, which incorporates several fundamental
wave-source patents.
NEXO’s sound reinforcement systems also
include the compact, versatile PS Series plus the
high performance Alpha System and Alphae Series. In
short, all NEXO loudspeakers, analogue and digital
controllers, power amplification, and advanced
rigging systems are designed to deliver: Sonic
Innovation That Works. NEXO is a world leader in the
design and manufacture of loudspeaker systems for
sound reinforcement.
PS Series systems can be used as floor
monitors or stand-mounted main PA
speakers, or flown as side and rear fill
coverage speakers with GEO and Alpha
System. PS systems can be installed
vertically or horizontally as main PA or
distributed/fill coverage speakers. Our
attention to the smallest sonic detail, no
matter your intended application, makes
the PS Series Systems the perfect sound
reinforcement solution.
Since the 1970s, NEXO has been a global leader
in research and development of loudspeaker and
complete sound reinforcement systems. Our
expertise focuses on integrated signal processing,
intelligent amplification, innovative transducer
and waveguide designs, enclosure materials and
hardware. While audio components designed in
isolation may individually achieve high
performance, making them work together often
requires time-consuming setup and delicate
adjustments. This is why we engineer all PS
system elements to function as an ensemble,
where the whole is even greater than the sum of
exceptional parts. The results yield unsurpassed
performance and reliability.
We apply specialized test and
measurement tools along with unique ideas to
the challenges of sound reinforcement, creating
a range of systems that are simple and easy to
use, while satisfying the most critical listeners.
Servo-controlled signal processing
driven by amplifier output monitoring is a
central element of NEXO systems. VCAs and
VCEQs instantaneously respond to amplifier

TDcontrollers (TD=Temperature Displacement)
also apply internal models of transducer
characteristics as failsafe protection. Whether
analogue, or digital, our advanced loudspeaker
system processors insure accurate reproduction
at extreme output levels.
THE ASYMMETRICAL ADVANTAGE
Above: Laser scanning
equipment helps evaluate
cone transducers such as the
neodymium PS8 woofer.
NEXO PS Series’ exceptional performance is
achieved by advanced system integration and
anchored by our Asymmetrical Dispersion
Constant Directivity horn design. As the
signature physical design feature in PS
systems, our asymmetrical horns are engineered
so that vertical coverage is narrower above horn
axis (+25°) than below (-30°), while horizontal
coverage is narrower above horn axis (50°
Horizontal for +25° Vertical) and wider below
(100° Horizontal for -30° Vertical). (see Figures
#1 and #2)
The obvious sonic benefits to this
asymmetrical coverage are that, when properly
used, PS systems significantly reduce the
amount of ambient, reverberant energy caused
when loudspeakers misdirect their output
towards walls and ceilings. In practice, this
means that PS Series asymmetrical horns allow
users to directly focus more loudspeaker output
on the audience, or performers (in monitor
applications), and less loudspeaker output
everywhere else.
A sticker on the wide dispersion side of
the PS horn indicates the correct orientation for
Front of House (FOH) and wedge monitoring
applications. (see figures on pg #2) The arrow
indicates the “wide side” of PS horn dispersion.
Users simply need to position the arrow so that it
points in the direction needing widest coverage
and away from the direction needing the
narrowest coverage.

COVERAGE
ACCORDING TO
NEED
For mobile system designs, our
asymmetrical horn design allows users to
quickly change horn coverage according
to need. The specific dispersion of PS8,
PS10 & PS15 horns can be seen on Figure
#1 ("FOH" configuration). Access to any PS
horn for inspection and configuration is
easily made by removing the front grille
with a gentle pull on the sides of the grille
to disconnect the press-stud fixings.
To modify horn orientation, remove the
four Allen 4 metric or TORX TX25 screws
(depending on model and age of the
cabinet) that secure the horn.
FRONT-OF-HOUSE CONFIGURATION
Good coverage of audiences often requires a
conflicting combination of wide coverage (“shortthrow”) for the closest listeners (below cabinet
axis) and narrow coverage (“long-throw”) for
distant areas (on or above axis). The PS Series
horizontal horn coverage varies from “shortthrow” to “long-throw” along the vertical axis to
match precisely these practical single system
requirements. In most applications, asymmetrical
horns should be used with the “wide” dispersion
side directed towards the floor (as referenced by
the arrow), but any of the four various horn
orientations are usable, depending on venue
geometry and room acoustics (see Figure #1).
STAGE MONITORS
Figure #2: (Above) With
horn rotated 180° from
Figure #1, this monitor
application provides a
wide (100°) sweet spot for
the performer’s listening
zones, and restricts
unwanted below-the-belt
coverage.
For stage monitors, the best coverage must be
wider when performers are closest to the wedge,
and above the horn axis, than when they move
away from the wedge and below the horn axis
(see Figure #2). The flexibility to be deployed in
this manner is one major reason why PS Series
loudspeakers are widely used in floor monitor
applications.
In this configuration, the PS horn must
be rotated so that its “wide side” dispersion is
in “wedge” position and that the directional
arrow is pointed towards the top of the
horizontally-oriented cabinet. This monitorfriendly dispersion combines with the PS Series’
exceptional power handling to yield unrivalled
foldback/monitor performance.

PS SERIES TD CONTROLLERS
Equalization and Subsonic/VHF Filtering
Because all PS cabinets are acoustically
designed for maximum efficiency, each TD
Controller applies strategic equalization
corrections to insure proper tonal balance and
system response. This active equalization also
extends PS Systems’ bandwidth, especially at
low frequencies where acoustical output is
limited by cabinet size. Active, rather than
passive, attenuation allows amplifier voltages to
be lowered for a specific output SPL, and
functionally increase the maximum possible SPL
from any PS amplifier.
Low and high-pass filters are used to
remove signals out of the usable frequency
range, eliminating sub and ultra-sonic
components that could potentially degrade the
performance of the Controller and amplifiers.
These filters are optimized to realize the overall
target system response.
Each of the three Audio channels (Left, Right
and Sub-bass) contains two voltage-controlled
elements driven by servo signals. The PS8Amp
and PS10Amp are power amplifiers tailored for
PS8 and PS10 systems and their respective
LS400 & LS500 sub-bass requirements.
The identical structure and power ofthese
3RU devices offers two or three-channel
instantaneous configuration via front-panel switch,
allowing 3-way use with the appropriate NEXO
SubBass or a wideband (2-way) configuration.
Power delivered by the amplifier is thus
optimized for the proper configuration. All
connections and controls are located on the front
panel including mains fuses and voltage
selection. Speaker wiring of each cabinet is
automatically re-assigned.
PS SERIES RIGGING AND FLYING
PS8, PS10 and PS15 have a built-in 35mm (1
3/8in) diameter stand adapter. Cabinets can be
positioned directly on a general-purpose speaker
stand or mast inserted in top-fitted stand
adapters on LS400, LS500 & LS1200 models. A
U-Coupler accessory allows relative rotation of
two side-by-side cabinets on top of the mast or
on a speaker stand. PS8 and PS10 mast and Ucouplers are optional. For safety reasons,
U-coupler use is not recommended with PS15
cabinets (see Figures #1, & #2).
PS10 OMNIMOUNT® STYLE CLAMPS
The back and bottom of the PS10 is equipped
with internal M8 metric anchor points for
Omnimount100 Series standard spacing. This is
particularly convenient for permanently installed
cabinets. Original screw removal requires a N°4
metric Allen key/TORX25.
PS8 ACCESSORIES
PS/LSub Crossover and Servo Control
From input signals summed together, the
resulting mono signal is low-pass filtered to feed
the Sub-bass channel. When the channel
configuration is set to Xover, the L&R main
channel's high-pass filters are switched to
bandpass (filter) signal components below the
crossover frequency. Slopes and other filter
characteristics are optimized using techniques
optimized for the each driver’s specific
acoustical data.

Performer’s perspective.
PS10 & PS15 FLYING RAILS & RINGS
PS10s and PS15s ship with steel anchor plates
intended for these optional fittings:
■ Top: 6-position aircraft-flying rail. (9 for PS15)
■ Bottom: Twin single-position round aircraft
flying rails, or two 3-position aircraft flying
rails for the PS15. These rails are supplied with
optional flying kits containing all necessary
screws and four single stud aircraft flying
rings. Heavy-duty double stud flying rings can
be used in all rails except on the PS10 bottom.
Vertical orientation of cabinets is a function of
top-rail ring position. For safety reasons two
rings must be linked, per rail, to two
independently fixed straps.
There are three PS8 mounting accessories. The
FS0081-001 is intended for direct mounting onto
the PS8 cabinet surface. It provides two M10
captive nuts that allow these three accessories
to be fitted:
■ Standard lighting hook/CLAMP
■ M10 lifting eye bolt
■ DIN Pivot (TV spigot)
The FS0081-002, which must be used with the
FS0081-001, provides two welded M5 nuts and
one welded M10 nut. This adapter allows the
cabinet to be fixed on the wall, ceiling, or on a
stand using the FS0081-003.
The FS0081-003 allows for Horizontal
Cabinet mounting on a stand or a 35mm mast. It
can be used with other accessories or fitted
directly to the cabinet.

PS8AMP
The PS8AMP is a dedicated amplifier that
allows PS8 Loudspeakers and optional
LS400 Subwoofers to achieve exceptional
performance from such compact
packages. The integrated PS8
TDcontroller provides specifically
optimised crossover, sensed-amplifier
control and system equalization for PS8
and LS400 cabinets.
The PS8AMP has L and R inputs and three
outputs, L, R and summed LSub out. The
PS8AMP Configuration switch
automatically configures the unit for 2channel mode (LSub Off), where the
PS8AMP drives two to four PS8
Loudspeakers in stereo
(2x 850Watts/4Ω) or 3-channel mode
(Lsub On), where the PS8 AMP drives two
PS8 Loudspeakers in stereo (2x
430Watts/8Ω) and one LS400 Subwoofer
(850W/4Ω) with a summed mono signal
of L+R input signals.
Like all NEXO processors, the PS8AMP
provides precision dynamic, voice coil
temperature and diaphragm
displacement protection through the
application of selective Voltage
Controlled Equalisers (VCEQs), reducing
levels only at frequencies when and
where necessary.

PS10 LOUDSPEAKER
The PS10 Loudspeaker can be safely
driven with over 500Watts of amplifier
power, yet it is only half the weight and
volume of common trapezoidal systems.
The dispersion, architecture and weight
balance of the PS10 Loudspeaker are
designed to provide both exceptional PA
and stage monitor performance from a
single product without compromise.
This flexibility is realized by a proprietary
constant directivity asymmetrical
dispersion horn, easily rotated in four
positions by the user. Coupled with the
horn’s unique progressive horizontal (50°
to 100°) and vertical (55°) dispersion, the
most suitable pattern can be selected for
vertical or horizontal PA usage, or
switchable active wedge monitoring. The
8Ω, 2-way passive design requires a
single amplifier channel to deliver biamped performance for less money,
space and complexity.

PS10 TDCONTROLLER ARCHITECT & ENGINEERING SPECIFICATIONS
The PS10 TDcontroller shall be configurable from a combination of 2x inputs and 3x outputs with each output providing crossover,
parametric EQ, adjustable peak limiter and Temperature & Displacement protection for NEXO PS10 and LS500 products. The unit
shall have electronically balanced analogue inputs and outputs. All crossover, protection parameters, and EQ are factory
optimized and can't be user-accessed. The controller must model the loudspeakers in real time and this modeling shall include
loudspeaker temperature and displacement. Protection shall be selective, acoustically transparent and not allow PS10
loudspeakers to exceed speaker-dependent thresholds. The device shall have 3x inputs providing feedback from amplifier output
to allow real time monitoring of amplifier voltage. Crossover function between PS10 loudspeakers and the LS500 Subwoofer shall
be controlled by the PS10 TDcontroller. Maximum input shall be 22dBu with CMRR 90dB@1kHz and noise floor below -100dB for
the 0dB rear-panel switch. A 3-position, rear-panel gain control switch shall be adjustable between -6/0/+6dB. The Output
Section shall display +22/+16/+10dBm into 600Ω load with Rear Panel switch on +6/0/-6dB (respectively). LEDs shall indicate
status for; Power ON (green), Amp Sense & Peak LED's (green/Red), Temperature & Displacement (yellow) and LS500 (VLF)
displacement protection (also yellow). The chassis shall be constructed of steel with a black paint finish. Input power shall range
from 110 to 220VAC continuously, 50-60Hz with a rear panel earth-lift. The 1RU controller shall weigh 2.9kg(6.4lbs), with exterior
dimensions of 483mmW x 44mmH x 190mmD (19" x 1.75" x 7.5"). The chassis shall be constructed of steel with a black paint
finish. The controller shall be the NEXO PS10 TDcontroller. Other integrated loudspeaker-controllers shall be acceptable, provided
independent laboratory test results verify these specifications are equalled or exceeded.
PS10AMP
The PS10AMP is a dedicated amplifier
that allows the PS10 Loudspeaker and
optional LS500 Subwoofer to achieve
exceptional performance from such
compact packages. The integrated PS10
TDcontroller provides crossover, sensed
amplifier control and system equalisation
optimised for the PS10 and LS500. Like all
NEXO processors, the PS10AMP provides
precision dynamic, voice coil
temperature and diaphragm
displacement protection through the use
of selective Voltage Controlled Equalisers
(VCEQs), reducing levels only at
frequencies when and where necessary.
The PS10AMP has two inputs, L and R, and
three outputs, L, R and summed LSub out.
The PS10AMP Configuration switch
automatically configures the unit for 2
channel mode (LSub Off), where the
PS10AMP drives 2 to 4 PS10 Loudspeakers
in stereo (2x 850 Watts/4Ω) or 3 channel
mode (Lsub On), where the PS10 AMP
drives 2 PS10 Loudspeakers in stereo (2x
430Watts/8Ω) and 1 LS500
Subwoofer (850W/4Ω) with a summed
mono signal of the L+R input signals.
Since the Configuration switch also rewires
the output connectors and displays
PS10AMP mode status with LED indicators,
the PS10AMP minimises installation cost
and complexity while ensuring faultless
performance.

PRODUCT FEATURES
■ High-power system (134dB Peak SPL @
1m) with 15in LF and 2in HF drivers.
■ Rotatable asymmetrical horn and unique
cabinet architecture ensure versatility;
user-adaptable for both PA and stage
monitoring applications.
■ Two-way, switchable passive or active
design for precise performance-matching
to user requirements.
■ Sophisticated control electronics ensure
reliable, linear operation.
■ Supported with a full range of mounting

PS15 LOUDSPEAKER
The PS15 Loudspeaker can be safely
driven with over 1000 Watts of
amplifier power, yet it has a small
volume and reduced weight. The
dispersion, architecture and weight
balance of the PS15 Loudspeaker are
designed to provide both exceptional PA
and stage monitor performance from a
single product without compromise.
This flexibility is realized by a proprietary
constant directivity asymmetrical
dispersion horn, easily rotated in four
positions by the user. Coupled with the
horn’s unique progressive horizontal (50°
to 100°) and vertical (55°) dispersion, the
most suitable pattern can be selected for
vertical or horizontal PA usage, or
switchable active wedge monitoring. The
8Ω, 2-way passive design requires a
single amplifier channel to deliver biamped performance for less money,
space and complexity.
