Installation 4 Installation Unpack and check carefully there is no transportation damage before using the unit. Keep the equipment packaging. To fully protect the product against vibration, dust and moisture during transportation or storage use the original packaging or your own packaging material suitable for transport or storage, respectively. Create all connections while the device is off. Use the shortest possible high-quality cables for all connections.
Installation CAUTION! Risk of injury due to heavy weight Due to the heavy weight of the device, at least two persons are required for trans‐ port and installation. CAUTION! Risk of injury due to improper installation Assembly and disassembly may only be carried out by qualified specialist per‐ sonnel. NOTICE! Possible property damage by magnetic fields Loudspeakers produce a static magnetic field.
Installation NOTICE! Use of stands When mounting the device onto a stand, ensure that the stand is in a safe and stable position and that the weight of the device does not exceed the maximum permissible load capacity of the stand. 4.1 Installation Overview Due to its mechanical structure, the device can either be individually put on the ground or hung, or arranged to line arrays of variable size. The units can be joined together using the built-in fasteners without any additional parts.
Installation Connecting the devices to each other To the left and right of the front panel, a safety pin is attached, allowing you to stably connect the unit to the one directly above it. There is a fold-out vertical latch on the rear panel. This latch fits into the U-rail of the device mounted below, which has a series of numbered bores. Attach the latch of the upper unit to the U-rail of the underlying device with a safety pin. By selecting the hole, you can set the desired angle of inclination.

Installation 1 Fold-out latch 2 Clearance bores. Fix the bolt in the hole for the desired angle. 3 Use this hole to fix the latch in the zero position.
Installation Installation of a flown system 1. Attach the flying frame left and right at the front panel of top unit. 2. Secure the flying frame with the locking pins that are attached to the top unit. 3. Position the vertical bar of the unit on the flying frame.
Installation 4. Secure the latch in the correct position with a safety pin at the U-rail. 5. For flying operation, mount a shackle on the flying frame. It must be located directly above the centre of gravity of the entire system. In the figure, the centre of gravity is marked by ‘C’, the arrow shows the correct position of the U-shackle for this installation situation. The maximum load capacity of the flying frame is 680 kg at an angle of 0°.
Installation Mounting multiple devices in a system Usually, several units are so installed to a line array, that they are arranged arcuately. The figure alongside shows an example of how four elements can be combined into a system that stands on the ground (ground stack). In a ground stack, no more than four elements with maximum angulation of 10° may be used. In flying operation, the shackle must be mounted just above the centre of gravity of the entire system.
Connections and controls 5 Connections and controls Rear panel line array element 24
Connections and controls 1 [INPUT] Audio signal input with lockable XLR chassis socket. The socket is electronically perfectly symmetrical wired to ach‐ ieve an optimal signal-to-noise ratio and a sufficient power reserve, including A / D conversion. 2 [GND LIFT] pushbutton If hum is caused by a ground loop, you can use this switch to disconnect the connection between the earth pin of the device and the signal ground of the device. Switching only has an effect when using balanced connection cables.
Connections and controls 7 Preset button This button has two functions: n If kept pressed while turning the device on, the ID assignment is made. The internal digital signal processor (DSP) assigns a new ID to the device for the remote control within the Pronet network. Each device must have a unique ID so that it can be represented in the Pronet network. If you assign a new ID, all devices with already assigned IDs must be turned on and connected to the Pronet network.
Connections and controls This LED lights up when the user setting is loaded. This setting corresponds to the user preset no. 1 of the DSP. In delivered condition, the user setting is identical to the setting [STANDARD]. If you want to change it, you must connect the device to a notebook/PC using the CanBus converter, edit the parameters using the Pronet software, and save the setting to user memory preset no. 1. 8 LED [SIGN/LIMIT] This LED lights green when an input signal is present.
Starting up 6 Starting up Switching on After you have made all the required connections, turn on the audio system. It is recommended to provide one switch for turning on the entire audio system and to always leave the power supply plugs (Power Twist) connected to the sockets of the individual units. With this simple trick you can extend the life of the connectors. DSP preset Set the desired DSP preset ([STANDARD], [LONG THROW], [DOWN FILL / SINGLE BOX] or [USER].
Networking and remote control 7 Networking and remote control Network capability Using the network ports on the rear panel, the individual devices of the entire audio system can be networked and remote controlled with a notebook / computer using the Pronet soft‐ ware. The communication protocol used in the Pronet network is CanBus.
Networking and remote control 1 Network ports on the rear panel of the first unit. 2 [TERMINATE] pushbutton must not be pressed. The LED above it is off. 3 Network ports on the rear panel of the last unit. 4 [TERMINATE] pushbutton must be pressed. The LED above it is on. Network setup and termination The individual units are linearly linked via RJ45 network cables. Beginning and end of the net‐ work bus must be terminated.
Networking and remote control ID assignment Each device of a Pronet network must have a unique identifier or ID. By default, the USB2CAND converter has the ID 0. Any other device can only have an ID equal or higher than 1. There must be no devices with the same ID on the network. The ID is assigned automatically when a device connected to the network is turned on for the first time. Proceed as follows to assign a unique ID to all devices in the Pronet network: 1. Turn off all devices. 2.
