JBL VRX900 - Manual (Page 20)

Maximum Array Size
There are three variations of the VRX array frame. The VRX-AF supersedes the VRX932AF-LA. The VRX-SMAF
is solely intended for use with the VRX928LA and VRX915S. Before suspending a VRX array, determine which
version of the array frame you have and consult the table below to determine the maximum number of speakers
that may be safely suspended. The subwoofers must always be at the top of the array.
VRX-AF Array Frame
The following table defines the maximum number of speakers that may be suspended using the VRX-AF frame.
A minimum design factor of 7:1 is maintained for all speaker configurations at or below those indicated in
the table.
VRX932LA-AF Array Frame
The following table defines the maximum number of speakers that may be suspended using the VRX932LA-AF
frame. A minimum design factor of 7:1 is maintained for all speaker configurations at or below those indicated in
the table.
VRX-SMAF Array Frame
The following table defines the maximum number of speakers that may be suspended using the VRX-SMAF
array frame. A minimum design factor of 7:1 is maintained for all speaker configurations at or below those
indicated in the table.
The VRX subwoofers must always be on top of the array.
Installing the Array Frame
The array frame is attached to the internal rigging of the VRX900 system using the provided Quick Release Pins
[Warning: Do not use any substitute for these pins].
1. Begin by attaching the two side arms (A) to either side of the center frame. Use a pair of the provided Quick
Release Pins (B)* to attach the arms to the frame. Note: Side
arms should be attached with the rubber bumper facing up and
away from the center frame. The center frame is installed with
the rubber gasket toward the enclosure and the label right side
up. [NOTE: The arms of the VRX932LA-AF and VRX-AF are
deliberately designed so as not to be interchangeable. The
arms of the VRX-SMAF are already attached.
2. Place the entire array frame on top of the VRX900 system
and flip up the drop levers (C) found on both sides of the
speaker to be received by the array frame arms.
3. Once the drop levers on the speaker are received by the
array frame, use a pair of the provided Quick Release Pins
(D) to attach the drop levers to the array frame.
