2.1 Product description
The Y8 line array module is intended for small to medium scale
sound reinforcement applications. When the Y Flying frame is
used, up to 24 cabinets can be flown in vertical columns producing
a constant directivity dispersion pattern of 80° in the horizontal
plane.
The Y12 line array module is acoustically and mechanically
compatible with the Y8 providing a 120° horizontal dispersion.
The Y8/Y12 cabinets are passive 2-way designs, both housing
2 x 8" neodymium LF drivers, one 1.4" exit HF compression driver
with a 3" diaphragm 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.
The two LF drivers are positioned in a dipolar arrangement
providing an exceptional dispersion control even at lower
frequencies with the nominal horizontal dispersion angle being
maintained down to 500 Hz.
The frequency response extends from 54 Hz to above 19 kHz.
The cabinets are constructed from marine plywood and have an
impact and weather protected PCP (Polyurea Cabinet Protection)
finish. The fronts of the cabinets are protected by a rigid metal grill
backed by an acoustically transparent foam. Each side panel
incorporates a handle while two additional recessed grips are
provided at the rear.
Y-Series rigging components and arrays
Y-Series arrays may consist of a combination of Y8 or Y12
loudspeakers and/or Y-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.
A detailed description of the Y-Series rigging components is given
in the Y-Series Rigging manual which is provided with the Y Flying
frame.
A detailed description of planning and designing Y arrays is given
in the technical information "TI 385 d&b Line array design,
d&b ArrayCalc" which is also provided with the Y Flying frame.
The d&b ArrayCalc simulation software can be downloaded from
the d&b website at www.dbaudio.com .
