Line Array Remote Alignment Display System

Line Array Remote Alignment Display System-Image

Rieker Inc's Remote Angle Display (RAD or RAS) instruments are specially designed for sound engineers who install and need to accurately align hanging line array (PA) speaker systems. Most of our customers have a number of speakers that they need to level but typically only want one display box. The LCD display is available as a single line reading one sensor at a time (RAS) or a dual line to measure two sensors simultaneously (RAD). For example, most V-Dosc users are purchasing the RAD2 dual line display with the REL feature being programmed to read Top - Bottom. Compatible with most all manufacturer line arrays including (but not limited to)  L-Acoustics , Meyer Sound, Paraline, DAS Audio and JBL.

A RAD or RAS system includes the display box along with a number of matched inclinometer sensors; typically 2 to 4. Both the sensor unit and the display box use standard type audio XLR cord plug connectors for easy connection. Installation is easy, and can be permanently mounted on the speaker or bumber, or installed per use.


1) RAD2 Remote Angle Display with dual line LCD allowing 2 remote sensors to be read at the same time.

2) RAS2 Remote Angle Display with single line LCD allowing 1 remote sensor to be read at a time.


Sensor Option A: an inclinometer sensor is mounted into Nema 4 box for extra protection, cable strain relief, and easier, more flexible mounting. Includes male XLR built into box. Can be configured to lay flat on top of the speaker box or on a flat vertical surface. It can be mounted with screws for a permanent installation or with gaff tape or heavy Velcro for easy removal for transportation and storage – please specify mounting position.

Sensor Option B: CS9. Solid Zinc housing, small footprint, sturdy and extra rugged for a more permanently mounted position. Very nice if you are using multiple line arrays and a RAD system together, not necessary to recalibrate each setup - once screwed into proper position, hang the speakers, plug in to display – mounts on a flat vertical surface.


Relative Zero (REL) Button: Standard on all display models: The REL button allows the user to set a new zero position after the RDI is mounted. Press the REL button and release and the display will read REL ON * for 1 sec then 0.00° *. The ( * ) indicates the measurement is not referenced to the true calibrated 0, but a referenced zero. The MIN/MAX angles are now referenced to the new referenced zero. Press the REL button again and the display will read REL OFF for 1 second then return to the true calibrated zero. The MIN/MAX angles are now again referenced to the true calibrated zero.

Relative Diff (REL) Button: (available on RAD displays only) This is programmed to give the difference between the TOP and BOTTOM sensors. The RAD2 with ±70º sensors scaled to -50/+90º, is a typical VDOSC configuration but the REL button is reprogrammed for SENSOR 1/SENSOR 2: SENSOR 1 would be placed on top of the speaker array = TOP LINE OF DISPLAY = TOP CONNECTOR on side of box; SENSOR 2 will be placed on the bottom of the speaker array = BOTTOM LINE OF DISPLAY = BOTTOM CONNECTOR on side of box.
