SCALABLE RESOLUTION
With exceptional line array performance guaranteed by the acoustic
design itself, scalable resolution unlocks the full potential of a
Wavefront Precision array and provides an adaptable pathway into the world
of advanced optimisation.
The greater the resolution of the array in terms of individually driven
enclosures, the more precisely DISPLAY can fine-tune audience coverage and
hold the frequency response and SPL’s throughout the venue within a tight
window specified by the user.

INCREASING RESOLUTION
For the first time in the marketplace the decision on the level of resolution
and control that is right for the install, client, event or budget is yours.
With scalable resolution, the commercial advantages are clear:
•Design systems to better suit project budget targets.
•Ability to increase resolution over time by buying more amps at later stage.
• Dynamic deployment within a venue or site where the main PA could be
driven by enclosures with more dedicated amp channels than may be
necessary for delays.

DESIGN AND MATERIALS
It’s not only the consistent coverage,
flexibility and scalable resolution
that set Wavefront Precision line
arrays apart. Their exceptional sonic
performance and exemplary horizontal
pattern control are born from Martin
Audio’s trademark, innovative approach
to high-efficiency acoustic design.
Wavefront Precision enclosures are
constructed from plywood and finished
in durable, easy-to-maintain textured
paint, with fabric-backed protective
steel grilles. Discreet side pocket
handles and rear grips are provided to
assist handling and splay-angle
adjustment, while integrated threepoint rigging systems assure efficient
and safe construction of arrays of up to
16 enclosures.

DISPLAY OPTIMISATION
DISPLAY is incredibly powerful. Based on an acoustic model accurate
to within ±1dB of measured data, it provides a virtual environment in
which arrays can be configured and optimised and delivers unrivalled
coverage consistency over the audience — right from switch-on. Also,
by reducing sound impacting non-audience areas, rear walls and ceilings,
the detrimental influence of the room can be significantly ‘dialled-out’ —
increasing clarity and intelligibility in challenging acoustic environments.
Step 1: Venue entry
Step 2: Set coverage parameters
Step 3: Calculate splay angles
Step 4: Optimisation and upload
DISPLAY leaves nothing to chance and takes the guesswork out of array
design and deployment — generating predicted frequency responses
throughout the venue and providing comprehensive rigging information,
including mechanical safety analysis.
Array DSP parameters calculated by DISPLAY are easily uploaded to the
iKON amplifiers via Ethernet, using Martin Audio’s VU-NET™ real-time
control and monitoring software.

AMPLIFICATION, DSP AND NETWORKING
Wavefront Precision line arrays are designed as complete systems with
dedicated, high-performance iKON multi-channel Class D amplifiers. Both
the iK42 4-channel amplifier and iK81 8-channel amplifier are capable of
very high power outputs and feature high-speed Ethernet communication
for system control and monitoring via VU-NET, plus Dante™ digital audio
networking. With the option to transmit digital audio over a single CAT5
cable, quality is maintained over long cable runs and integration with other
devices in the sound system is straightforward.
Because the amplifiers are external to the loudspeaker enclosures, the
resolution of the array can be increased as required by simply adding more
amplifier channels to drive more array enclosures independently — increasing
the level of control available to DISPLAY to fine-tune coverage and reduce
room influence. External amplifiers also facilitate ease-of-servicing in fixed
installations.
Both the iK42 and iK81 provide powerful DSP processing of up to 1000
FIR filter taps @ 48kHz on each output channel. This high number of taps is
essential to implement DISPLAY’S wide bandwidth optimisation capabilities.
The complete system approach not only guarantees that Wavefront Precision
arrays perform repeatedly and effortlessly to their design maximum, but also
that they are compatible worldwide.
iK42/iK81 FEATURES
•Four/eight channels of Class D amplification
•Onboard DSP on all inputs and outputs
•FIR filtering on each output
•Switch mode, global voltage power supply
•20,000 watts (iK42)/10,000 watts (iK81) total RMS output
•Intuitive front panel user interface
•Ethernet network for system operation and monitoring via VU-NET
•Analogue, AES3 and Dante™ digital network audio inputs
•Extensive protection and monitoring

The WPC is a new breed of medium-format optimised line array which brings innovative acoustic
design, ultra-high performance and coverage consistency to a wider range of users, applications
and budgets than previously possible. A three-way, bi-amp system, it features horn-loaded lowfrequency, mid and HF sections to raise efficiency and increase output. Its high efficiency
acoustic design can equal or outperform larger, direct radiator systems — a 12-box array will
throw beyond 60 metres (200ft) and deliver impressive rock levels to a 5000-seat venue,
saving on truck space and weight.
10
The WPC’s low frequency section consists of 2 x 10” (250mm) neodymium
drivers in a Hybrid® configuration which marries the benefits of horn and reflex
loading. Each driver is slot-loaded into a short horn to give a high sensitivity
of 103dB @ m/2.83V, while the rear of the driver is reflex-loaded to extend the
LF output. The punch and low-frequency extension produced from such a small
enclosure volume are remarkable.
Mid and HF horns are physically separate — a key factor in the WPC’s exemplary
100° horizontal constant directivity dispersion pattern. The midrange horn
design utilises 2 x 5” (125mm) neodymium drivers to produce a high SPL
of 109dB @ 1m/2.83V, while the HF section employs 4 x 0.7” (19mm) exit
neodymium compression drivers which feed 4 individual horns. Use of multiple
small HF drivers instead of a more traditionally-used large format compression
driver results in less distortion and a more extended HF response.

The WPM is incredibly versatile. Its very small footprint and light weight make it the system
of choice for smaller venues which require superb fidelity, coverage consistency and control
from an ultra-compact line array. It is also very powerful — 12-box array will throw beyond 35
metres (115ft) and produce live music at high levels in up to 3000-seat venues. It embodies
the very latest acoustic technology in an ultra-compact enclosure and is the ideal system for
small-to-medium scale theatres and live music venues, AV events and installations in concert
halls, ballrooms and HoW.
12
A passive 2-way system with an impedance of 16 ohms, it can be driven in
blocks of 1, 2, 3 or 4 resolution configuration. With a complement of 2 x 6.5”
(165mm) LF drivers and a vertical column of 3 x 1.4” (35mm) aluminium
dome HF drivers, the acoustic design of WPM is uniquely innovative. The
LF drivers are located in the side walls of the HF horn — an arrangement
which would introduce acoustic cavities which would degrade the horizontal
dispersion if conventional cone drivers were used. WPM’s drivers adopt an
elegant solution by having solid moulded diaphragms which match the contours
of the horn walls and maintain the continuity of the horn profile. Each LF driver
also features a demodulation ring in the neodymium motor system to minimize
distortion and maximise mid-band output.
In the triple-driver HF section, each individual HF wavefront is preciselycoupled to the horn throat via a short waveguide for faultless 100° horizontal
constant directivity coverage.

SX SUBWOOFERS
SX118
The WPC and WPM can be augmented by ground-stacked
SX118 and SX218 subwoofers. Installation-specific subwoofers
such as the CSX118/218 may also be used. Cardioid operation
can be achieved by arranging the subwoofers in forward and
rear-facing pairs, and the iKON amplifiers deliver the correct
drive characteristics to the subs via onboard DSP presets for a
variety of system configurations.
The SX118 is a compact, high performance subwoofer that extends
the low frequency operating range of the system to 47Hz and provides
exceptional low frequency output for such a compact enclosure. An ideal
partner for the WPM, it features a long-excursion 18” (460mm)/4” (100
mm) voice coil driver with a water-resistant cone and triple roll surround
in a compact reflex enclosure.
The design of the 18” driver maximises output while minimising power
compression and distortion, and the four reflex ports have a large frontal
area to reduce turbulent air noise at very high levels. The enclosure
is constructed from multi-laminate birch ply, finished with a durable
textured coating and equipped with a steel grille, twin grab handles,
skids, flying inserts for installation and a threaded pole socket for polemounting up to 4 WPM enclosures as a simple plug-and-play system.
SX218
The SX218 achieves the ultimate in subwoofer performance for the
most demanding applications – delivering very high output levels and
superb transient performance with minimal distortion it is the perfect
partner to WPC, with one subwoofer to every 2 top boxes required. With
an operating range of 35Hz-150Hz ± 3dB, it houses dual 18” longexcursion (460mm)/4” (100mm) voice coil drivers with water-resistant
cones and triple roll surrounds. Each driver is rated to handle 1000
watts AES, and has a magnet structure and suspension engineered for
maximum linear excursion.
The enclosure is constructed from multi-laminate birch ply and coated
with hard-wearing textured paint. Eight reflex ports provide a large frontal
area to reduce turbulent air noise, and a perforated steel grille protects
the drivers from damage.
