V12 Arc/V12 Line

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.

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.
