The d&b ArraySight is a laser inclinometer system designed to precisely aim an entire loudspeaker array in its operating position, providing accurate angle measurements over a wide range. It is an integrated part of the d&b rigging system and should be handled with the same care as any other rigging component.
The ArraySight system consists of a sender unit and a meter unit. The sender unit, a compact, weather-resistant device (IP54), utilizes a 3-axis MEMS accelerometer for data acquisition, enabling accurate tilt sensing over one axis, even when the unit is tilted on another. It also incorporates a thermo- and hygrometer sensor to measure onsite temperature and humidity, with these values displayed on the meter unit's screen or accessible via the d&b Remote network (R1).
A key feature of the sender unit is its ultra-bright green laser, which provides a visible indication for aiming the array. This laser can operate in a flashing mode to enhance visibility in bright surroundings. The system offers intelligent interpolative measurement, allowing for accurate readings even before the array has reached its final resting angle after hoist adjustment. The meter unit automatically displays the final resting angle within three oscillation periods, reducing installation time by eliminating the need to wait for the system to come to rest.
The ArraySight system supports both absolute and relative angle measurements. The sender unit stores calibration information in non-volatile memory, ensuring accuracy even after disconnection from the meter unit. This allows for easy calibration and resetting of the angle to zero at any point within its range, facilitating adjustments in absolute values. The meter unit's zero function enables relative angle measurements, and the last four readings are stored for quick recall.
For integration into larger systems, the sender unit supports the d&b OCA/AES70 protocol, allowing it to be directly integrated into the d&b ArrayCalc simulation and R1 Remote control software. This enables multiple sender units to be read out within R1.
The sender unit is designed for safe mounting to dedicated d&b Flying frames using enclosed fixing screws. It should not be fixed with tape or velcro. When making adjustments with motor hoists, users are advised to focus on the hoist and only check measurements once the hoist has stopped moving.
The meter unit features an intuitive on-screen menu system with a detailed graphical display and backlight for visibility in all light conditions. Navigation is done via two buttons below the display: the left-hand button for scrolling through menu items and the right-hand button for selecting functions.
To power on the meter unit, both buttons below the screen are held down until the d&b logo appears, followed by the "Home" screen displaying the current angle readout. To power down, the same procedure is followed until a "Shutting down" message is displayed.
The "Home" screen provides essential information: the actual onsite temperature ("T"), humidity ("H"), battery status, and the current angle readout. From this screen, users can access the main menu ("Menu") or the laser function ("LASER"). The laser can be switched on, set to flashing mode, or turned off by pressing the right-hand button.
The main menu offers access to "Meter settings" and "Sender settings." "Meter settings" include "History" (displaying the last four readings), "Auto power" (defining the auto power-off timer), "Temp. unit °C/°F" (setting temperature units), and "Version" (displaying firmware versions). "Sender settings" allow configuration of "IP settings" (IP address, subnet, gateway, IP mode) and "Remote ID" settings (subnet and device ID for OCA networks), and "Reset angle" (zeroing the angle).
Resetting the angle (zeroing) is crucial for accurate measurements. This involves placing the flying frame on a solid, stable, and flat surface, ensuring the sender unit is correctly aligned and the frame is horizontally and vertically leveled using a spirit level. Once aligned, the angle can be reset to zero via the meter unit's menu. This offset value is stored in the sender unit.
Laser alignment is a critical procedure to ensure the beam is emitted precisely on a central axis. This should be performed in a workshop setting, not on site, by connecting the sender unit to the meter unit and projecting the laser onto a vertical surface 10 meters (33 ft) away. The laser's alignment is adjusted using three M3 machine screws around its bezel until the dot aligns precisely. After alignment, thread-locking fluid should be applied to the screw heads to prevent loosening.
The ArraySight units are designed for maintenance-free service during normal operation. For cleaning, only a soft cloth should be used; solvent cleaners should be avoided, and no liquids should be sprayed directly onto the LC display or laser.
To prevent damage from moisture or liquids, especially during transport or when not in use, the dust cap of the etherCON connector socket on the sender unit must be properly attached (closed). This protects the connector socket's spring contacts from corrosion.
Calibration of the accelerometer in the sender unit is performed at the factory using precision jigs. Re-calibration should only be attempted if appropriate facilities are available to ensure accuracy, as incorrect calibration can lead to inaccurate measurements. The calibration procedure, accessed via the meter unit's "Calibrate" menu, involves a six-step process of placing the sender unit in specific orientations (z+, z-, x+, x-, y+, y-) to use gravity as a reference. The laser must be switched off throughout this procedure. The calibration data is stored in the sender unit's non-volatile EEPROM. Regular safety inspections are obligatory for all rigging components, including the ArraySight system.
