Vi rigging components and arrays
Vi arrays may consist of a combination of Vi8 and Vi12
loudspeakers and/or Vi-SUB cardioid subwoofers.
Cabinets are mechanically connected using the rigging strands on
both sides of the cabinet front and a central strand at the rear of
the cabinet. All necessary rigging components are mounted to the
cabinet and fold out or slide out when needed.
Note: The Splay link of the Vi-TOP cabinet is designed as a
straight link with drilled holes, as shown in the graphic
opposite. For visual reasons the Splay link of the last cabinet
of an array can easily be removed.
A detailed description of the Vi rigging components is given in the
Vi Rigging manual which is provided with the Z5387.xxx
Mounting frames.
A detailed description of planning and designing V-Series arrays is
given in the technical information "TI 385 d&b Line array design,
d&b ArrayCalc" which is provided with the V Flying frame.
The d&b ArrayCalc simulation software can be downloaded from
the d&b website at www.dbaudio.com .
2.2. Connections
The cabinet is fitted with NLT4 F/M connectors. All four pins of
both connectors are wired in parallel. The cabinet uses the pin
assignments 1+/1–. Pins 2+/2– are designated to actively driven
subwoofers. Using one connector as the input, the second
connector allows for direct connection to a second cabinet.
Cabinets with the weather resistant option (WR) are equipped with
a fixed input cable (PG type, H07-RN-F, 2 x 2.5 mm

d&b LoadMatch
Starting with the D80 amplifier platform, the LoadMatch function
enables the amplifier to electrically compensate for the properties
of the loudspeaker cable used without the need for an additional
sense wire. For applicable loudspeakers, LoadMatch is therefore
independent of the connector type used.
