2.1 – Determining the installed waveguide and orientation
There are two waveguides supplied with the R5 loudspeaker, and each waveguide is
rotatable meaning there are four possible waveguide dispersion combinations.
To make identifying which waveguide is installed simple and quick, there is a viewing
recess in the enclosure on each side where the grille meets the enclosure woodwork.
Simply look in this small recess, and the identifying label will show which waveguide is
fitted and its orientation.
The 80x50 waveguide has blue indicator labels, and the wider 110x50 waveguide has red
indicator labels.
NOTE:
The arrows indicate the dispersion in the direction shown – in the example above, the label
indicates that the 110° x 50° horn is fitted and is oriented so it is 50° in the vertical plane
(and therefore 110° in the horizontal plane).
By default, the R5 ships from the factory with the 80x50 waveguide fitted, and the
dispersion pattern 80° horizontal x 50° vertical when the loudspeaker is in a portrait
format. In this format, the label showing in the viewing recess would be:
