The Martin Experience

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.

Standards Applied EMC Emission EN55103-1:1996

Immunity EN55103-2:1996

Electrical Safety EN60065:1993

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.

Martin Audio – WAVEFRONT PROFESSIONAL SERIES

ENGLISH

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.

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.
