1 Unpacking Thank you for purchasing a Martin Audio W8VDQ system. Each Martin Audio W8VDQ 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. We suggest 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 distributo

3.2 Free standing Ensure that the floor, stage, platform or subwoofer is level and solid Ensure that the front of the W8VDQ does not overlap the front edge of the stage, platform or subwoofer. System stability relies on the whole front width of the W8VDQ – not just it’s central foot Outdoor systems – or systems accessible by the audience – must be strapped down for safety Be aware that speakers producing very high power levels can vibrate, move or creep. Again, strapping will keep

The yoke may be turned upside down for an alternative tilt angle range… Alternative orientation 4 Aiming for best coverage The W8VDQ is designed for medium coverage – up to 25m distance x 100deg (120deg in the nearfield). Height The W8VDQ should always be mounted so that the bottom/foot is about 1m above near-field listener head- height (or 1m above front balcony listener level when used for a balcony fill) for the differential coverage to work correctly. Nearfield attenuati

Aiming The W8VDQ can cover approximately 30deg vertically. The easiest way to set the tilt angle for maximum rear audience level is to aim the top section of the grille straight towards the furthest seat. See Maximum level to farfield line below… Note that the W8VDQ’s differential dispersion does not allow vertical arraying or stacking. The Martin Audio W8LM line array system provides optimal vertical coupling for vertical array applications. Horizontal arraying (up to 60-100deg be

This policy avoids clipping transient peaks. Clipping not only sounds unacceptable but can seriously stress your system by dumping large amounts of distortion into the high frequency drivers - especially in passive mode. Controllers The W8VDQ must be used with a Martin Audio DX1.5, DX2 or Engineer controller system to ensure correct operation and protection. DX1.5 (New for November 2008) 2 input, 6 output digital loudspeaker management system The DX1.5 is a powerful 2in-6out DSP

7 Cable lengths When connecting W8VDQ 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 Warranty Martin Audio ceiling loudspeaker products are warranted against manufacturing defects in materials or craftsmanship over a period of 5
