When connecting a balanced signal, be sure it's wired per AES (Audio Engineering Society) standards: XLR Hot (+) Pin 2 Cold (-) Pin 3 Shield (Ground) Pin 1 Balanced XLR Connectors There is also a male XLR connector labeled LOOP OUT. This is also wired according to the above AES standard. The LOOP OUT connector allows you to connect more than one SA1532z to your system. Simply plug the signal source (i.e., mixer output) into the first MAIN INPUT jack, and patch that speaker's LOOP OUT jack to the next MAIN INPUT jack, and so on, daisy-chaining multiple speakers. The LOOP OUT jack is wired straight from the MAIN INPUT connector - there is no electronic circuitry between - so the signal coming out of the LOOP OUT jack is exactly the same as the signal going in. PLACEMENT The SA1532z speaker is designed to sit on the floor or stage. WARNING: The cabinet has no rigging points and is not suitable for rigging. NEVER attempt to suspend the SA1532z by its handles. The SA1532z should never be pole-mounted. You can create a horizontal array by placing the cabinets side-by-side. However, you should have a good understanding of the relationship between the splay angle (the angle between the facing sides of the cabinets), the on-axis power, and frequency cancellation effects between cabinets. When two cabinets are placed side-by-side, the actual splay angle is 20º (determined by a 10º angle on each cabinet side). As the splay angle increases toward the angle of horizontal coverage (90º for the SA1532z), the on-axis power decreases, but the frequency response becomes smoother as the comb-filtering effects (caused by the interaction in the area of double-coverage) decrease. As with any powered components, protect them from moisture. If you are setting them up outdoors, make sure they are under cover if you expect rain. 5
