The Remote Angle Display (RAD or RAS) was specially designed for speaker positioning. Most of our customers have a number of speakers that they need to level but typically only want one display box. We can supply the display 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). For example, most V-Dosc users are purchasing the RAD2 dual line display with the REL feature being programmed to read Top - Bottom, please let us know what system you are using.
A RAD or RAS system includes the display box along with a number of matched sensors; typically 1, 2, or 4 sensors. Both the sensor unit and the display box use standard type audio XLR cord plug connectors for easy connection. We normally do not supply the interface cables, most customers make their own cables to meet their required length. We can supply cables if necessary, however, we have found that customers who are in the speaker and lighting industry already have an abundance of XLR cable and can get it much cheaper than we can. 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.
We have two choices on sensor ranges - 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. For example, we have a number of customers selecting the ±70° sensor and having them scaled to read +50° to -90°. (Typical V-Dosc application.)
The RAD2 Remote Angle Display with dual line LCD allowing 2 remote sensors to be read at the same time.
The 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. Mounting feet are available.
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.
