The CDD-LIVE 8 is an ultra-compact, self-powered, two-way system featuring an 8” (200mm) LF/1” (25mm) exit HF Coaxial Differential Dispersion driver which can be easily rotated for horizontal or vertical orientation. Its small size gives no indication of its high output capability and exceptional fidelity. As a stand-alone loudspeaker, it has a multitude of professional applications — from small-medium scale sound reinforcement, AV presentations and HoW to distributed systems, frontfill/infill and use as a micro stage monitor.
With wide coverage close-up, the Coaxial Differential Dispersion technology employed in the CDD- LIVE 8 delivers more consistent audience coverage than systems with fixed X° x Y° coverage patterns, and its innovative CDD driver achieves ‘point source’ summation of the LF and HF sections — eliminating off-axis variations in frequency response associated with non- coaxial designs.
A self-powered system, the CDD-LIVE 8 incorporates a two- channel Class D amplifier, DSP and DanteTM digital audio networking — simplifying set-up, enhancing control and eliminating amplifier racks. The onboard amplifier delivers 1000W LF + 300W HF peak output to the drivers, and its switched-mode power supply auto-ranges to global mains voltages from 100 to 240V 50/60Hz.
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-NETTM proprietary software.
For simple set-ups, ‘plug-and-play’ presets — as well as a user- defined preset — can be selected on the rear panel, instead of using computer control. As an alternative to its analogue inputs, the CDD- LIVE 8 is Dante enabled for digital audio distribution and control over a single CAT5 cable to maintain audio quality however long the cable run.
The CDD-LIVE 8 is incredibly versatile. Its multi-angle enclosure can be used in either horizontal or vertical orientation, with rotation of the driver easily accomplished by removing the screw- free, protective grille. The tour-grade enclosure is constructed from multi-laminate plywood and finished in a hard-wearing polyurea coating. Integral fittings include a top-hat for pole mounting and multiple M8 inserts for attachment to a wall- bracket, yoke or universal bracket with a wide range of up and down tilt angles.

Technical Specifications
Architectural Specifications
The loudspeaker shall be a self-powered two-way system ultilising Coaxial Differential Dispersion technology. Its transducers shall consist of a reflex-loaded 8” low frequency driver and a coaxially-mounted 1” exit high frequency compression driver loaded by a static waveguide that merges with moving waveguides added to the cone of the low frequency driver to define the HF horn geometry.
The coaxial driver shall be user-rotatable to enable vertical or horizontal operation as required by the application. Horizontal dispersion shall vary from 110° to 80° and vertical dispersion shall be 60°. The on-axis frequency response shall be 70Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 123dB peak at 1 metre.
The loudspeaker shall incorporate a two-channel Class D amplifier module which shall deliver a total of 1300W peak output to the transducers and include onboard DSP and networking capabilities for remote control and monitoring. The loudspeaker shall be DanteTM enabled for Audio over IP. Its power supply shall employ Power Factor Correction and operate from 100-240V, 50-60Hz AC.
Audio connectors shall be male and female XLR type and the AC power connector shall be a Neutrik® Powercon True1. Network connectors shall be Neutrik® Ethercon RJ45 type.
The loudspeaker enclosure shall be constructed from multi-laminate plywood with a textured polyurea coating. The drivers shall be protected by a perforated steel grille with scrim cloth backing and the enclosure shall be fitted with a pole-mount socket and threaded inserts for mounting accessories.
An IP24 rating version with a rain cowl shall be available as a factory option.
Dimensions (W x H x D) shall be 258mm x 428mm x 254mm (10.2in x 16.8in x 10.0in). Weight shall be 14kg (30.8lbs).
The loudspeaker shall be the Martin Audio CDD-LIVE 8.
