RAD2 - Remote Angle Display Inclinometers

The RAD2 Remote Angle Display with dual sensors, the latest addition to Rieker’s RDI Series of digital inclinometers, was specifically designed for speaker and speaker array positioning. This battery-powered digital LCD box can be matched with a number of Rieker sensors, which can then be used interchangeably with the display box to coordinate multiple remote speaker locations.




“Our customers in sound system installation or audio/video contracting typically have a number of speakers that they need to level and only want one display box to configure the array,” said senior engineer Joann Coates. “We can supply the LCD as a single-line display reading one sensor at a time [RAS] or a dual-line display to measure two sensors at the same time [RAD].” Both sensor and display box use standard-type audio XLR cord plug connectors for connection. In most cases, the sensors are permanently mounted on the speakers with cables running down to the floor. The cable connector is then plugged into the display box as needed.

The sensor ranges come in either ±30° (60° total range) or ±70° (140° total range). The display can be calibrated to anywhere within the total range of the sensors specified. Skip Gosnell, the marketing director for Rieker, said, “We have a number of V-DOSC or similar line array installers, for example, who are purchasing the RAD2 dual-line display with the REL feature being programmed to read top–bottom and selecting the ±70° sensors and having them scaled to read +50° to -90°.”

The REL button (relative zero) allows the operator to temporarily zero the digital readout to obtain relative angle changes. The Min/Max function provides the smallest and largest angle that the device has sensed since it was last reset. The optional Relative Difference function can be programmed to give the difference between the top and bottom sensors.
