Now select the number of cabinets deep that you wish to hang or stack in the “Box Count”
dropdown. Trim height, or PA wing height can now be set in the “Position” field.

If a mix of Low and High cabinets are to be used then select in the Cabinet window the type
and location in the array of each box. The angle between cabinets can now be set in the
“Angle” list. Each cabinet has an aiming line that can be used to determine the centre of each
cabinet’s dispersion. Adjust the trim height, top angle and intercabinet angle to achieve
optimum coverage.
