INTRODUCTION

Thank you for purchasing this Martin Audio CDD loudspeaker system.
The Martin Audio CDD Series has been designed to fulfil the need for high performance
sound in pubs, bars, restaurants, retail premises, nightclubs, conference facilities, theatres,
educational institutions, places of worship, museums, exhibition centres and cruise ships, in an
ultra-compact package.
CDD speakers deliver the highest quality audio over a wide area, with consistent coverage
throughout the venue.
The cabinets are styled to be architecturally unobtrusive. CDD enclosures (except for the CDD5)
are constructed from rigid, moulded UPM Formi, a fibre composite material combining stiffness
with excellent damping properties. The larger models (CDD8 upwards) have birch ply baffles and
all models feature flush, acoustically transparent steel grilles. Subwoofers are built in heavily
braced MDF enclosures. Enclosures come in either a white or black finish; with other RAL
colours available to order.
The CDD range of loudspeakers use two-way, full-range co-axial drivers, incorporating Martin
Audio's exclusive Differential Dispersion™ horn technology. Passive crossovers optimised for the
drivers are fitted, obviating the need for bi-amping. The crossover frequency is between 1.6 kHz
and 2.5 kHz, depending on model.
The CDD range consists of six full-range units, with drivers from 5" to 15". These are supplemented
by a range of four CSX sub-woofers with single or dual 12", or single or dual 18" LF drivers.
Systems may be used individually or in multiples to suit a wide variety of applications. Link
connectors are fitted to facilitate daisy-chain wiring.
Versions of the CDD5 and CDD6 are also available for 70/100 V-line operation. These models,
the CDD5TX and CDD6TX respectively, include a high quality tapped transformer and a power
setting switch, to allow the speakers to be used with the 70 V-line or 100 V-line distribution
systems used for announcements and background music in office complexes, hotels and similar
large buildings.
A wide range of installation accessories is also available, permitting wall, ceiling or flown mounting.
Mounting hardware is suitable for first and second fix construction industry conventions.
All CDD and CSX models may also be ordered as weatherproof (WR) versions: these are suitable
for deployment in locations where they may be subject to moisture (e.g., swimming pools, near
water features, etc.), or rainfall. CDD-WR models are rated IP54, while CSX-WR models are
rated IP24.
This User Guide provides a detailed explanation of the CDD's features and options. Please take
the time to read through the Guide even if you are experienced with other Martin Audio products.
Thank you again for placing your confidence in Martin Audio products.
