Dual VRX932LA/VRX928LA

Unlike most conventional speakers, the VRX932LA/VRX928LA 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 SS4-BK speaker pole and SRX718S subwoofers. Do not stack more than two VRX932LA/VRX928LA speakers on a pole.

Locking (2) VRX932LA/VRX928LA Loudspeakers Together

Any time two or more VRX932LA/VRX928LAs 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. Safe combinations are:

VRX918S with VRX932LA VRX915S with VRX928LA

WARNING: Only the correct quick release pins supplied by JBL are to be used.
