The JBL SRX906LA PB accessory is a lightweight pull-back bracket that can be used to implement pull-back of SRX906LA or SRX910LA arrays. The SRX906LA PB attaches to the bottom cabinet of an array and connects to a rear center suspension point to allow for more downtilt than would otherwise be possible using an SRX900 Series array frame alone. JBL's Line Array Calculator 3 software application is used to calculate the required downtilt angle. The SRX906LA PB can support the weight of up to 16 SRX906LA or 16 SRX910LA enclosures (depending on array geometry) and a 1/2-inch shackle (included) can be attached directly to the bracket. For more information about the suspension bar and use cases, refer to the SRX900 Series Rigging Manual.
