Maximum Array Size

There are two variations of the VRX array frame. The VRX-AF which is dark gray in color supersedes the
VRX932AF-LA (which is black). 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 VRX932LA and VRX918S speakers
that may be safely suspended. The VRX918S 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.

Installing the Array Frame

The VRX932LA-AF or VRX-AF Array Frames (see previous section) are designed specifically for suspension 
of VRX932LA and VRX918S arrays. The array frame is attached to the internal rigging of the VRX918S or
VRX932LA 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.]

2. Place the entire array frame on top of the VRX932LA or VRX918S 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.
