User manual ELECTRO-VOICE 1776

[. . . ] Loosen the wing screw until the dolly board is able to rotate freely. Turn the dolly board 90°, and tighten the wing screw (see Figure 2). If the dolly boards are removed, replace the (2) 5/16" bolts into the rear of the enclosure. If the bolts are not replaced, the speaker will have air leaks resulting in undesirable performance.

The dolly plates double as skid plates for extra protection of the PX2181's back panel. Remove (16) 5/16" bolts from rear of the PX2181 enclosure. Align holes in the PX-D2 with the holes on the PX2181 enclosure, and tighten the (16) 5/16" bolts into the dolly boards (see Figure 3). CAUTION!If the dolly boards are removed, replace the (16) 5/16" bolts into the rear of the enclosure. If the bolts are not replaced, the speaker will have air leaks resulting in undesirable performance. Remove Existing Screws, Install Dolly Plates, then Re-attach Screws (16 Places) Fully Installed Dolly Plates Figure 3: Assembling the PX-D2 to a Phoenix PX2181 Loudspeaker PX-G1 The Electro-Voice® PX-G1 is an array kit that allows for suspension of up to (3) PX2122's or (2) PX2152's on a material lift. There are multiple horizontal splay and vertical tilt options that make the PX-G1 useful in many applications. Suspending any object is potentially dangerous and should only be attempted by individuals who have a thorough knowledge of the techniques and regulations of rigging objects overhead. Electro-Voice® strongly recommends that all speakers be suspended taking into account all current national, federal, state and local regulations. It is the responsibility of the installer to ensure that all speakers are safely installed in accordance with all such regulations. Make sure the pins for each material lift adaptor pass through their respective holes in material lift forks, and fully lock or engage other side of material lift adaptors. Do not lift any array without ensuring pins pass through forks and are fully locked or engaged. Material Lift Adaptors Long Pin Figure 9: Assembling the Material Lift Adaptors to Material Lift Forks 5. Attach the material lift adaptors to the array bracket using the short pins (See Figure 10). There are 17 holes on the array bracket (A-Q) that can be used to approximate the desired vertical tilt angle. See the table below to determine which holes should be used to achieve the desired tilt angle. Material Lift Forks and Adaptors Short Pin Array Bracket Short Pin WARNING!Make sure the pins for each material lift adaptor pass through their respective holes in array bracket, and fully lock or engage other side of material lift adaptors. Do not lift any array without ensuring pins pass through bracket and are fully locked or engaged.

Following safe rigging practices, attach rated safety cabling (not included) from the material lift to the eyebolts (See Figure 12). [. . . ] Do not attempt to tilt an array beyond the angles shown in the chart. Figure 11: Vertical Tilt Angle Configurations Installation of the PX-G1 (continued) 6. Following safe rigging practices, attach rated safety cabling (not included) from the material lift to the eyebolts (See Figure 12). The center of gravity of the array is located below the hole on the material lift forks. Never exceed the load limits or the maximum load height that is specified by the material lift manufacturer.
