Mixed Arrays With A8 And B18; Attaching The Array Frame To The B18 - JBL VTX Series Rigging Manual

11 - MIXED ARRA YS WITH A8 AND B18
VTX A8 cabinets are mechanically and acoustically compatible with VTX B18 single-18-inch subwoofers. All A8 suspension accessories
are compatible with the VTX B18, enabling mixed arrays with VTX A8s suspended under B18 subwoofers to be created.
This section of the manual covers creating mixed VTX A8/B18 arrays. For more detailed information on the B18 rigging system and how
to create standalone B18 suspended arrays, refer to the VTX B18 Rigging Manual.
11.1 A TT ACHING THE ARRA Y FRAME TO THE B18
The first step in this process is attaching the VTX A8 AF Array Frame to the top VTX B18 cabinet. The array design used for this exam-
ple, consists of two forward-facing B18 subwoofers, with eight A8 cabinets under them. Below is the procedure for attaching the array
frame to the first B18.
STEPS:
• For easiest attachment, separate the Array Frame from the Extension Bar.
1
• Remove the quick release pins securing the four B18 rigging arms. The spring-loaded mechanism will extend the arms outside
2
the B18. Restore the QRPs to their previous positions.
• Lower the Array Frame onto the B18 and use the four QRPs to secure it.
3
• Once the Array Frame is secured to the top of the cabinet, the Extension Bar can be attached.
