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.
