Until now, most self-powered portable loudspeakers have been underpowered, light-duty systems or very high-end systems out of reach of many users. Now, with the multi-purpose CDD-LIVE! Series, Martin Audio brings everything rental companies, system integrators and musicians require from a self-powered loudspeaker into sharp focus.
CDD-LIVE! The Sound of things to come.
Comprising three full-range models andtwo subwoofers, CDD-LIVE! covers practically all professional stand-alone anddistributed applications — from sound reinforcement and monitoring for livebands, DJ’s and corporate events, to installations in dance clubs, ballrooms,theatres and performing arts centres.
Combining the ‘point-source’ benefits of coaxial designs with theconsistent coverage of Differential Dispersion technology, CDD-LIVE! full-rangesystems project sound evenly front-to-back while exhibiting wide horizontalcoverage close to the speaker — delivering ultimate fidelity and impact to allcorners of the audience.
Onboard Class D amplification, DSP and Dante™ Digital Audio networkingassure simplicity of stage set-up and efficient installation, while tour-gradeenclosures and comprehensive mounting options — including pole mount, wallbrackets, yokes and rigging inserts — provide maximum flexibility indeployment.
With sonic consistency across the range, a rectangular coveragefootprint and a multitude of deployment options, CDD-LIVE! is truly versatile —the professional self-powered solution that means business.
COAXIAL DIFFERENTIAL DISPERSION™: THE BEST OF BOTH WORLDS
CDD-LIVE! combines the ‘point-source’benefits of coaxial designs with the consistent coverage of DifferentialDispersion technology.
All CDD-LIVE! full-range models feature Martin Audio’s unique, patentedCoaxial Differential Dispersion™ technology to deliver perfect sound to everymember of the audience.
THE COAXIAL ADVANTAGE
Non-coaxial systems can suffer from uneven frequencyresponse in the crossover region because the outputs of the LF and HF sectionsinterfere with each other, causing variations off-axis, depending on thelistening position. This is especially true close to the loudspeaker.
In contrast, coaxial systems can achieve ‘point-source’ summation ofthe LF and HF sections at all positions off-axis, even close-up. This is onereason that coaxial devices are often used for nearfield applications such asstudio monitoring.
Conventional Coaxial Beamwidth CDD Beamwidth (horizontal)
Significantly, until now one disadvantage of conventional coaxial devices has been high frequency beaming, where the high frequency dispersion reduces as the frequency increases. This is primarily because conventional coaxial devices channel high frequencies through a narrow tube in the pole-piece of the magnet system. CDD-LIVE! coaxial devices overcome this by incorporating an innovative static waveguide that merges seamlessly with the unique cone shape — maintaining the dispersion pattern out to very high frequencies.
THE DIFFERENTIAL DISPERSION™ ADVANTAGE
A Differential Dispersion horn has a 3D trapezoid dispersion pattern which covers a room more evenly than a system with a conventional, fixed-dispersion X° x Y° type horn.
With a conventional X° x Y° horn, the speaker is usually placed justabove head height and aimed towards the centre of the audience. This producesan imperfect coverage pattern which misses out some areas — particularly sideareas close to the loudspeaker.
In contrast, a CDD-LIVE! Coaxial Differential Dispersion system produces a rectangular coverage pattern to reach all corners of the audience,and wide horizontal coverage is achieved very close to the loudspeaker. Walking the room, the consistency in frequency response and SPL — both close to the loudspeaker and further back — is exceptional. The improved coverage close-up also means that CDD-LIVE! speakers can be spaced further apart in some installations, reducing overall speaker count, and similarly a reduction in frontfill / infill speakers in a live sound environment.
ONBOARD AMPLIFICATION, DSP AND DIGITAL NETWORKING
Each CDD-LIVE! system incorporates apowerful electronics module with on-board DSP, Class D amplification and Dante™digital audio networking — simplifying set-up, enhancing control andeliminating amplifier racks.
Lightweight, switched-mode power supplies auto-range to global mainsvoltages from 100 to 240V 50/60Hz, while Power Factor Correction smoothes outthe mains current draw over the whole of the AC waveform.
DSP functions — including parametric EQ, delay, muting, gain and presetselection — can be controlled over Ethernet from a PC or Windows tablet viaintuitive VU-NET™ proprietary software.
For simple set-ups using CDD-LIVE! full-range systems, three‘plug-and-play’ factory presets for full-range, stage monitor and operationwith subs — as well as a user-defined preset — can be selected on the rearpanel, instead of using computer control. Four LEDs indicate which preset isselected and can also be switched to operate as a signal level meter. Eachsubwoofer has presets for operation with either the CDD-LIVE 8, 12 or 15, plusa user-defined preset. Additional presets provide the appropriate settings forthe rear-facing subwoofer in a cardioid pair.
An optional rain cowl is available for outdoor use.
THE DANTE ADVANTAGE
Dante is an uncompressed, multi-channeldigital media networking technology. It is the preferred audio networkingsolution of the pro-audio industry owing to its outstanding audio quality andinteroperability that is easy to install, easy to set up, versatile, scalableand economic.
Each CDD-LIVE! system is Dante enabled. Delivering significantimprovements in Audio over IP technology in terms of speed, high channel countand with near-zero latency, Dante networking opens up tremendous opportunitiesfor digital audio distribution and control — from a front-of-house live musicsystem to a large-scale installation with multiple locations and zones. Withaudio transmitted digitally over a single CAT5 cable, quality is maintainedhowever long the cable run and integration with other devices in the soundsystem is straightforward.
Setting up a Dante network is simple — even complex networks can beconfigured easily and quickly, with all devices discovered and displayed in theDante Controller software. Once set-up, the computer running Dante Controllercan be removed from the network if desired, with system settings stored in thedevices themselves and automatically restored when a device is power-cycled.
Switching between XLR analogue inputs to Dante on CDD-LIVE! enclosuresis automatic if a digital stream is present, unless the user selects the XLRoption in VU-NET.
CDD-LIVE! systems are incrediblyflexible and complemented by a comprehensive range of mounting accessories.
The CDD-LIVE 8, 12 and 15 can be pole mounted — either directly usingtheir integral pole-mount fittings or with the addition of a universal bracketwith a wide range of up and down tilt angles. The up/down tilt angle is easilyadjustable and lockable in place. The universal bracket can also be attached toa scaffold clamp for vertical or horizontal suspension from a truss.
Horizontal yokes are available for the CDD-LIVE 12 and 15, while panand tilt wall brackets for the CDD-LIVE 8 and 12 mount the enclosures as closeto the wall as possible. The wall brackets feature a lift-off capability thatenables the wall-mounted section to be first-fixed, with the speaker addedlater.
The CDD-LIVE 8, 12 and 15 are fitted with multiple M8 threaded insertsfor eyebolt suspension. The CSX-LIVE 118 and 218 are fitted with M10 inserts.
