7 QUICK START GUIDE
The other option is to set up the system using the pole mount option, as shown in Figure 6 .
A maximum of 2 x BRX308-LA speakers may be mounted on the pole adapter kit that is available for purchase as part of the
BRX308-PM Kit.
It is advised to use an inter-box angle of at least 2° between each BRX308-LA to allow for wide enough vertical coverage of the high
frequencies.
The pole mount adapter bar allows for the following angles for the first mounted box: 0, -2, -3, -4, -5, -6, -8, -9, -10, -11 and -12°.
The negative angles allow the first box to aim downwards and cover audience members that are closer to the array.
To set the first box at the desired -ve angle value, align the desired value on the adapter bar (see Figure 7) to the bottom of the box
and lock it in place with the Quick Release Pin in the matching hole.
We recommend an inter-box angle of 10° or 12° for the second box. This allows for more uniform coverage from front to back.
The system sub/top balance in this pole mount configuration will have more sub energy (when compared to the ground stack option
using 1 sub + 4 tops). We recommend reducing the sub volume from the mixer if required.
