1 INTRODUCTION
Thank you for purchasing a Martin Audio Wavefront Professional Series
system. The Wavefront Professional Series is a range of powerful yet
compact loudspeakers designed to suit a variety of professional
applications. The trapezoid shape of the enclosures allows them to be
used singly or arrayed in multiples. Specific uses include live sound
reinforcement, theatre sound and audio-visual events.
2 UNPACKING
Each Martin Audio loudspeaker is built to the highest standard and
thoroughly inspected before it leaves the factory. After unpacking the
system, examine it carefully for any signs of transit damage and inform
your dealer if any such damage is found. It is suggested that you retain
the original packaging so that the system can be repacked at a future date
if necessary.
Please note that Martin Audio and its distributors cannot accept any
responsibility for damage to any returned product through the use of
non-approved packaging.
3 OVERVIEW
The Wavefront Professional Series consists of the W0.5 and WM0.5
miniature full-range systems, the W1, W2 and W3 compact full-range
systems and the WS2A sub-bass. For optimum performance it is
recommended that Wavefront Professional Series loudspeakers are used
with the WX3A System Controller or an appropriate digital controller such
as the Martin Audio DX1. Please refer to the controller user guide for
information on connections and limiter settings.
3.1 W0.5 and WM0.5
The W0.5 is a miniature high performance loudspeaker suited to a variety
of applications from sports bars to live sound infill. It is a passive two-way
system featuring an 8" (200mm) bass driver and a 1" (25mm) ferrofluid
cooled HF driver on a 70 x 50 degree horn.
The WM0.5 is a wedge monitor version of the W0.5, utilising the same
drive units and horn. In its wedge configuration, the horn of the WM0.5
exhibits a 50 x 70 degree dispersion pattern to increase the listening
window in the vertical plane. The base of the WM0.5 is provided with
threaded steel inserts for use with a tripod or for mounting upside down
close to a ceiling.

3.2 W1
The W1 is an ultra-compact passive two-way system with a high output
capability for its small size. Featuring a 10" (250mm) bass driver and 1"
(25mm) compression driver on a 70 x 40 degree horn, it is particularly
useful in distributed sound and audio-visual appplications.
3.3 W2
The W2 is a powerful stand-alone system combining dynamic full-frequency
performance with exceptional articulation. Designed to meet the industry
standard requirement for a 12" (305mm) bass driver plus 70 x 40 horn
combination, the W2 can be configured as either an active or passive
system by means of a switch on the rear of the enclosure.
3.4 W3 and W3P
The W3 is an innovative full-range system achieving true three-way
performance from an enclosure only 28" (711mm) high. The low frequency
driver is a powerful 15" (380mm) device cooled by a heat exchange system
to reduce power compression. Midrange is produced by a unique 6.5"
(165mm) mid horn developed to overcome the power and distortion
limitations of traditionally used large format compression drivers whilst high
frequencies are produced by a 1" (25mm) compression driver. Mid and HF
dispersion patterns are 65 x 40 degrees. The W3 is a three-way system
designed for bi-amplification at its 650Hz low/mid crossover point. A fully
passive version, the W3P is available for situations which require simplicity
and reduced amplifier count.
3.5 WS2A
Where a Wavefront Professional Series enclosure requires additional low
frequency enhancement, the WS2A will extend the power bandwidth of the
system to below 35Hz. It utilises twin high power 15" (380mm) drivers with
4" (100mm) voice coils in an optimally tuned compact reflex enclosure.
NOTE:
Passive systems such as the W0.5, WM0.5, W1, W2 (in passive mode) and
W3P may be used without a WX3A controller provided recommended
amplifier power is not exceeded and care is taken to avoid amplifier
clipping. Use of an optional WX3A controller with its system specific low
frequency EQ and built in limiters will result in improved bass response and
system protection.

4 SAFETY FIRST
It is important that loudspeaker systems are used in a safe manner. Please
take some time to review the following points concerning safe use of
Wavefront Professional Series loudspeakers.
Professional loudspeakers are capable of producing extremely high sound
levels and should be used with care. Hearing loss is cumulative and can
result from levels above 90dB if people are exposed for a long period.
Never stand close to loudspeakers driven at high level.
4.1 Tripod Mounting
The W0.5, W1, W2 and W3 incorporate a pole mounting socket to facilitate
mounting on tripod stands. When using stands, the following precautions
are advised:
Ensure that the stand will support the weight of the speaker by checking
the stand manufacturers rating.
Make sure that the stand is placed on a level surface and that its legs are
fully extended.
Do not place more than one speaker on each stand.
Run cables so that they do not present a trip hazard which could pull the
speaker over.
When used outdoors in the wind, it may be necessary to add some weight
to the base of the stand.
When using a pole mount with a sub-bass system such as the WS2A,
observe similar precautions.
4.2 Stacking
Ensure that the floor or stage is level and solid.
Do not stack speakers too high outdoors where winds could topple the
stack.
Be aware that speakers producing very high power levels can move or
creep. To avoid this, place friction material between the floor and speaker
and between each speaker.
4.3 Rigging and Suspension
WARNING: Suspending the system should only be done by qualified
personnel following safe rigging practices. Secure fixings to the
building structure are vital. Seek help from architects, structural
engineers or other specialists if in any doubt.

The W0.5, WM0.5, W1, W2 and W3 are provided with threaded inserts to
allow the suspension of a single enclosure. Never suspend one
enclosure from another to form an array or cluster using these
fittings. The W2 and W3 are provided with optional MAN flying points for
array construction.
The common practice of using commercially available eye bolts for
suspension should only be undertaken with great caution. Eye bolts are
strongest along the thread axis. Angling the enclosures will result in an
angle pull and it is important to use eye bolts that are safe in these
circumstances. Only forged shoulder eye bolts should be considered and it
is important that the thread length is at least 30mm. A flat washer should be
inserted between the eyebolt and the enclosure. Formed eye bolts i.e.
those which are formed from a steel rod bent into an eye should be
avoided.
5 AMPLIFICATION
Wavefront Professional Series loudspeakers are designed to be used with
professional power amplifiers capable of producing the following power
outputs into 4 ohms:
W0.5 & WM0.5 300-400W
W1 300-400W
W2 400-600W
W3 400-600W
W3P 550-800W
WS2 550-800W
Care should be taken to avoid amplifier clipping. It is important to
understand that a low power amplifier driven into clipping is more likely to
damage a loudspeaker than a higher power amplifier used within its ratings.
This is because music signals have a high peak-to-average "crest" factor.
When an amplifier is severely overdriven, its output waveform is clipped (its
peaks are squared off) – reducing the crest factor. In extreme cases, the
waveform can approach that of a square wave. An amplifier is normally
capable of producing far more power under these conditions than its
undistorted rated power output.
The use of very high power amplifiers with outputs greater than those
recommended is discouraged.
Care should be taken to avoid switch-on surges, which can result in
momentary power peaks in excess of specified ratings. When powering up
a sound system it is important to switch on the amplifiers after the mixer
and control electronics have stabilised. When powering down the system,
reverse the sequence and switch off the amplifiers first.

1+ Input +ve Low +ve
2- N/C (Mid)/High -ve
2+ N/C (Mid)/High +ve
7 CABLE LENGTHS
When connecting loudspeaker systems to an amplifier, it is recommended
that the return resistance of the cable used is less than one tenth of the
nominal impedance of the system or systems in parallel. The table below
gives an indication of the maximum permissible cable runs for various
conductor cross-sectional areas.

8 SYSTEM CONFIGURATIONS
The W0.5, WM0.5, W1, W2 and W3 may be used to cover the full-frequency
range – either distributed singly or arrayed in multiples. The WX3A and DX1
controllers provide appropriate system-specific low frequency equalisation for
full-frequency operation. Where additional low frequency output is required,
a WS2A sub-bass system driven from a separate amplifier fed from the sub-
bass output of the controller can be added.
Wavefront Professional Series loudspeakers combined with the appropriately
configured controller exhibit an essentially flat on-axis frequency response.
Equalisation to compensate for a particular acoustic environment may be
performed where required. Where loudspeakers are arrayed, they may
benefit from a degree of equalisation to reduce the effect of the low/mid build
up and tilting of the response inherent in the use of multiple arrayed
enclosures.
