1.1. Information regarding the use of loudspeakers

Potential risk of personal injury

Never stand in the immediate vicinity of loudspeakers driven at a
high level. Professional loudspeaker systems are capable of
causing a sound pressure level detrimental to human health.
Seemingly non-critical sound levels (from approx. 95 dB SPL) can
cause hearing damage if people are exposed to it over a long
period.

In order to prevent accidents when deploying loudspeakers on the
ground or when flown, please take note of the following:

– When setting up the loudspeakers or loudspeaker stands,

make sure they are standing on a firm surface. If you place
several systems on top of one another, use straps to secure
them against movement.

– Only use accessories which have been tested and approved

by d&b for assembly and mobile deployment. Pay attention to
the correct application and maximum load capacity of the
accessories as detailed in our specific "Mounting instructions"
or in our "Flying system and Rigging manuals".

– Ensure that all additional hardware, fixings and fasteners used

for installation or mobile deployment are of an appropriate
size and load safety factor. Pay attention to the manufacturers'
instructions and to the relevant safety guidelines.

– Regularly check the loudspeaker housings and accessories for

visible signs of wear and tear, and replace them when
necessary.

– Regularly check all load bearing bolts in the mounting devices.

Potential risk of material damage

Loudspeakers produce a static magnetic field even if they are not
connected or are not in use. Therefore make sure when erecting
and transporting loudspeakers that they are nowhere near
equipment and objects which may be impaired or damaged by an
external magnetic field. Generally speaking, a distance of 0.5 m
(1.5 ft) from magnetic data carriers (floppy disks, audio and video
tapes, bank cards, etc.) is sufficient; a distance of more than 1 m
(3 ft) may be necessary with computer and video monitors.

2.1. Product description

The Vi8 is a line array loudspeaker for medium to large-scale
sound reinforcement. When the V Flying frame is used, up to 24
cabinets can be flown in vertical columns producing an 80°
constant directivity dispersion pattern in the horizontal plane.

The Vi12 line array loudspeaker is acoustically and mechanically
compatible with the Vi8 and provides a 120° horizontal
dispersion.

The Vi8 cabinet is a passive 3-way design housing 2 x 10"
neodymium LF drivers, one horn-loaded 8" MF driver, two 1.4" exit
HF compression drivers with 2.5" diaphragms mounted to a
dedicated wave shaping device and a passive crossover network.
The wave segments of each cabinet couple without gaps and sum
up coherently. Splay angles between adjacent cabinets can be set
in the range from 0° to 14° with a 1° resolution.

All components are arranged symmetrically around the center axis
of the cabinet to produce a perfect symmetrical dispersion pattern.
This setup allows for a crossover design with a well defined
overlap of adjacent frequency bands resulting in a very consistent
and accurate horizontal dispersion. Due to the dipolar
arrangement of the low drivers broadband horizontal dispersion
control is maintained down to approximately 250 Hz.

The frequency response extends from 67 Hz to above 18 kHz.

The cabinet is constructed from marine plywood and has an impact
and weather protected PCP (Polyurea Cabinet Protection) finish.
The front of the loudspeaker cabinet is protected by a rigid metal
grill backed by an acoustically transparent foam. Two additional
recessed grips are provided at the rear bottom of the cabinet.

Cabinet options

The WR option enables operation of loudspeakers in changing
ambient conditions, however it is not intended to enable
permanent, unprotected operation of loudspeakers outdoors.

– Provide an additional cover over the entire loudspeakers/

array.

– Aim the entire array either horizontally or with a downward

tilt.
