Locking (2) VRX932LA Loudspeakers Together
Any time two or more VRX932LAs are arrayed together, they must be mechanically secured to each other using
the integral rigging frame and supplied quick release pins. See the diagram below for details. WARNING: Only
the correct quick release pins supplied by JBL are to be used.

Dual VRX932LA
Unlike most conventional speakers, the VRX932LA is designed so that a pair of
speakers may be safely mounted onto a pole or tripod stand. For most applications,
the forward socket of the dual angle pole socket will be used. This will tilt the lower
of the two speakers at a 15° down-angle (providing coverage of the near listeners)
while the upper speaker will face straight out (covering the more distant areas).
Ideally, the listeners should not be able to see either the bottom or the top surfaces
of the two-speaker array. Usually, the Array Configuration Selector (ACS) switches
on the lower speaker's input panel should be set to the "Short Throw (-3 dB)"
position while the upper speaker will be set to either "Short Throw (-3 dB)" or
"Mid Throw (0 dB)".
Place the speakers on the pole or tripod one at a time. Be sure to lock the two
speakers together using the integral rigging hardware (see below). System illustration
shows available JBL SS4BK speaker pole and SRX718S subwoofers. Do not stack
more than two VRX932LA speakers on a pole.
