1. System safety

1.1. Intended use

The xA-Series rigging components (Flying bar, Flying bar adapter, Connector plates) must only be used in conjunction with d&b xASeries loudspeakers as described in this rigging manual.

Installation and setup should only be carried out by qualified and authorized personnel observing the valid national Rules for the Prevention of Accidents (RPA).

It is the responsibility of the person installing the assembly to ensure that the suspension/fixing points are suitable for the intended use.

Always carry out a visual and functional inspection of the items before use. In case you have any doubt as to the proper functioning and safety of the items, these must be withdrawn from use immediately.

1.2. Load capacity

1.2.1. Approved array configurations

The xA-Series rigging system is designed to allow the following approved array configurations for indoor applications.

Flown arrays Ground stacks

Array configuration Number and type of cabinets

Configuration Number and type of cabinets

10AL Line array – Up to 9 x 10AL (-D) cabinets. Mixed ground stack – Up to 6 x 10AL (-D) cabinets on

top of up to 3 x 18A or 27A subwoofers as ground support.

10A Vertical array – Up to 6 x 10A (-D) cabinets. SUB stack – Up to 4 x 18A or 27A

subwoofers.

Mixed arrays – Up to 6 x TOP cabinets

combined with up to 2 x SUB cabinets at the top of the array.

– Up to 3 x cabinets at the top of

the array with up to 2 x SUB cabinets in-between and up to 3 x TOP cabinets at the bottom.

SUB column – Up to 4 x 18A subwoofers.

– Up to 3 x 27A subwoofers.

1.2.2. xA-Series loudspeaker cabinet weights

Cabinet Weight in kg (lb)

10A (-D)/10AL (-D) 14 kg (31 lb)

18A-SUB 32 kg (71 lb)

27A-SUB 41 kg (90 lb)

1.3. ArrayCalc / TI 385

For safety reasons xA-Series arrays must be designed using the d&b ArrayCalc simulation tool. The software is available for download at

www.dbaudio.com.

The use of ArrayCalc is described in the technical information TI 385 "d&b Line array design, d&b ArrayCalc", which is also provided with this rigging manual.

Carefully read this TI to become familiar with the operation and behavior of ArrayCalc and in particular with the mechanical load conditions and limitations.

We also recommend you to attend the regularly hosted d&b xASeries training seminars. Further information regarding the d&b seminars can be requested directly from the d&b audiotechnik sales partners.

1.4. Operational safety

During assembly pay attention to the possible risk of crushing. Wear suitable protective clothing.

Observe all instructions given on the rigging components and the loudspeaker cabinets.

When chain hoists are in operation, ensure that there is nobody directly underneath or in the vicinity of the load who is not involved in the setup.

Do not under any circumstances climb on the array

2. Rigging concept

d&b xA-Series, Rigging manual (1.1 EN)6

2.1. Tool box

– Hex head socket wrench (Torque wrench) #13 mm. – Screw driver with torx bit TX30. – Torx socket wrench (Torque wrench) with torx bit TX45. – Allen hex key 5 mm. – Securing glue (such as Loctide®).

2.2. xA-Series rigging components

The xA-Series loudspeaker cabinets together with the xA-Series rigging components allow the setup of various array configurations, either flown or ground stacked.

The following overview provides a basic description of the intended use of each component.

2.2.1. xA-Series loudspeaker cabinets

The cabinet side panels are equipped with integrated rigging points to accept the corresponding xA connector plates.

To attach the connector plates, the rigging points can easily be accessed by removing the cover plates.

Once the respective connector plates are attached to both sides of the cabinets, the cover plates are refitted to build a solid mechanical connection between the cabinets or to the flying bar.

2.2.2. Z5413 Flying bar connector plate xA

Intended use

The Flying bar connector plate xA is used to connect the flying bar to the entire array. For this purpose, the connector plate is equipped with two pairs of holes.

The lower pair is used to connect the flying bar to SUB cabinets, if these are integrated at the top of the array.

To connect the flying bar to 10A (-D) or 10AL (-D) cabinets, either the lower or the upper pair can be used. Using the upper pair allows the flying bar to be connected as close as possible to the first cabinet of the entire array.

The connector plate is equipped with an additional suspension hole of 12.5 mm [0.5"] [S] to allow the suspension of the array (dual pickpoint operation) using a 1t Shackle (e.g. d&b E6507) instead of the flying bar adapter.

The connector plate can also be used to attach a second pickpoint at the end of the array to act as a pullback anchor device, if required.
