CDD-LIVE! THE SOUND OF THINGS TO COME

Combining the ‘point-source’ benefits of coaxial designs with the consistent coverage of Differential Dispersion technology, CDD-LIVE! full-range systems project sound evenly front-to-back while exhibiting wide horizontal coverage close to the speaker — delivering ultimate fidelity and impact to all corners of the audience.

Onboard Class D amplification, DSP and Dante™ Digital Audio networking assure simplicity of stage set-up and efficient installation, while tour-grade enclosures and comprehensive mounting options — including pole mount, wall brackets, yokes and rigging inserts — provide maximum flexibility in deployment.

With sonic consistency across the range, a rectangular coverage footprint 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

It combines the ‘point-source’ benefits of coaxial designs with the consistent coverage of Differential Dispersion technology. All CDD-LIVE! full-range models feature Martin Audio’s unique, patented Coaxial Differential Dispersion™ technology to deliver perfect sound to every member of the audience.

THE COAXIAL ADVANTAGE

Non-coaxial systems can suffer from uneven frequency response in the crossover region because the outputs of the LF and HF sections interfere with each other, causing variations off-axis, depending on the listening position. This is especially true close to the loudspeaker.

In contrast, coaxial systems can achieve ‘point-source’ summation of the LF and HF sections at all positions off-axis, even close-up. This is one reason that coaxial devices are often used for near-field applications such as studio monitoring.

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 just above head height and aimed towards the centre of the audience. This produces an imperfect coverage pattern which misses out some areas — particularly side areas 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 a powerful electronics module with on-board DSP, Class D amplification and Dante™ digital audio networking — simplifying set-up, enhancing control and eliminating amplifier racks.

Lightweight, switched-mode power supplies auto-range to global mains voltages from 100 to 240V 50/60Hz, while Power Factor Correction smoothes out the mains current draw over the whole of the AC waveform.

DSP functions — including parametric EQ, delay, muting, gain and preset selection — can be controlled over Ethernet from a PC or Windows tablet via intuitive 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 operation with subs — as well as a user-defined preset — can be selected on the rear panel, instead of using computer control. Four LEDs indicate which preset is selected and can also be switched to operate as a signal level meter. Each subwoofer has presets for operation with either the CDD-LIVE 8, 12 or 15, plus a user-defined preset. Additional presets provide the appropriate settings for the rear-facing subwoofer in a cardioid pair.

An optional rain cowl is available for outdoor use.

THE DANTE ADVANTAGE

Dante is an uncompressed, multi-channel digital media networking technology. It is the preferred audio networking solution of the pro-audio industry owing to its outstanding audio quality and interoperability that is easy to install, easy to set up, versatile, scalable and economic.

Each CDD-LIVE! system is Dante enabled. Delivering significant improvements in Audio over IP technology in terms of speed, high channel count and with near-zero latency, Dante networking opens up tremendous opportunities for digital audio distribution and control — from a front-of-house live music system to a large-scale installation with multiple locations and zones. With audio transmitted digitally over a single CAT5 cable, quality is maintained however long the cable run and integration with other devices in the sound system is straightforward.Setting up a Dante network is simple — even complex networks can be configured easily and quickly, with all devices discovered and displayed in the Dante Controller software. Once set-up, the computer running Dante Controller can be removed from the network if desired, with system settings stored in the devices themselves and automatically restored when a device is power-cycled.

Switching between XLR analogue inputs to Dante on CDD-LIVE! enclosures is automatic if a digital stream is present, unless the user selects the XLR option in VU-NET.

MULTI-PURPOSE FLEXIBILITY

CDD-LIVE! systems are incredibly flexible and complemented by a comprehensive range of mounting accessories. The CDD-LIVE 8, 12 and 15 can be pole mounted — either directly using their integral pole-mount fittings or with the addition of a universal bracket with a wide range of up and down tilt angles. The up/down tilt angle is easily adjustable and lockable in place. The universal bracket can also be attached to a scaffold clamp for vertical or horizontal suspension from a truss.

Horizontal yokes are available for the CDD-LIVE 12 and 15, while pan and tilt wall brackets for the CDD-LIVE 8 and 12 mount the enclosures as close to the wall as possible. The wall brackets feature a lift-off capability that enables the wall-mounted section to be first-fixed, with the speaker added later.

The CDD-LIVE 8, 12 and 15 are fitted with multiple M8 threaded inserts for eyebolt suspension. The CSX-LIVE 118 and 218 are fitted with M10 inserts.
