OPTION 1 - GROUND STACK OPTION
The most common use case for the BRX300 system is the ground stack option, as shown above.
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 BRX308-LA has captive rigging hardware that
allows for inter-box angles of 0, 1, 2, 3, 4, 5, 6, 8, 10
and 12°.
To set the inter-box angle to any of the values
mentioned above, align the bottom box’s angle bar
‘Lock’ hole to match with the desired angle value on
the top box and lock it in place with the Quick Release
Pin (Figure 1: Angle Bar 0° shows an example angle
bar setting of 0°).
When setting inter-box angles of 8° and above, the
angle bar of the upper box may obstruct the angle
bar from the below box from aligning with the desired
value. In such cases, the angle bar of the upper
box must be stored using the Quick Release Pin in
the ‘Standby’ hole (as seen in Figure 2: Angle Bar
Standby).
