Vi8 V8 Arc/V8 Line 2
Vi12
V12 Arc/V12 Line 2
The applicable d&b amplifiers provide two setups ("Arc" or "Line")
for the Vi8 and Vi12 loudspeakers. These are available in Dual
Channel or Mix TOP/SUB mode.
"Arc" and "Line" setups
The selection of "Arc" or "Line" depends on the curvature of the
array. Both setups may be used within one array.
The "Arc" setup is intended for line array loudspeakers when used
in curved array sections.
The "Line" setup is used for long throw array sections with three or
more consecutive splay settings of 0°, 1° or 2°. Compared to the
"Arc" setup, the mid/high range is reduced to compensate for the
extended nearfield.
The transition from "Line" to "Arc" configuration within the array is
made according to the splay progression but may allow for certain
deviations due to the wiring of the cabinets in groups of up to two.
2.3.1. Controller settings
For acoustic adjustment the functions CUT, CPL and HFC can be
selected.
CUT mode
Set to CUT, the low frequency level of the cabinets is reduced. The
Vi8/Vi12 array is now configured for use with the d&b Vi-SUB or
J-SUB subwoofers.
