2. Align the laser level with the top of the speaker. You may find that there is some side-to-side drift, but this will not affect how you obtain the vertical angle. 3. Angle the DSR1090 vertically until the laser is directed at the specified aiming point, as shown in the following figure. -
Page 18: Installing The Safety Cable
Attention: To properly fit into the DSR1090 threaded inserts the eyebolt must contain a threaded shaft that is at least 20 mm long. Based on the weight of the DSR1090 (31 lb [14 kg]), all installer- supplied safety rigging hardware must be rated at a minimum 5:1 safety factor, or greater if a higher requirement is mandated per local laws. -
Page 19: Connecting And Configuring The Dsr1090
Consult building plans and a licensed professional engineer, and follow all local laws for overhead mounting. 3.5 Connecting and configuring the DSR1090 About this task After mounting the DSR1090 to the building structure and connecting a safety cable, you must follow instructions for connecting and configuring the DSR1090. Required tool: Wire stripper Caution: Turn off all amplifiers when connecting speaker wiring. - Page 20 Note: In 5.1 and Dolby Surround 7.1 installations, it may be better to daisy-chain (series/parallel) several DSR1090 speakers. You can do this by twisting the wire pairs and inserting them into the input connector following steps 3 and 4 of the preceding procedure. When daisy-chaining speakers, always verify that the driving amplifier specifications rate the amplifier at the appropriate level to handle the resulting load impedance of the combined daisy-chained speakers.
