The Electro-Voice® ZX1i is the new standard of no compromise audio performanceand versatility in an easy to install, compact sound reinforcement package.

The high-tech enclosure uses injection-molded high-impact polypropylene to makethe ZX1i extremely durable. The enclosure geometry has been engineered toprovide maximum rigidity and acoustic performance. The velocity compensatedport design overcomes the limitation of many small cabinet loudspeakers andenables exceptional low-frequency response without vent noise.

ZX1i installation is incredibly simple with the included QuickSAMTM mounting sys-tem. The QuickSAMTM is a unique, integrated mounting bracket which is virtuallyfoolproof. It allows the installer to simply snap the speaker onto the bracket, thentighten it to the desired position. For array mounting, there is an optional arraybracket kit available which allows multiple units to be mounted together for a varietyof configurations.

Zx1i uses a special circuit that when in transformer mode the network re-configuresitself to a current actuated Hi-Pass filter at the transformer primary. It gently rollsry. It gently rollsry

the higher (vocal) frequencies and the program continues without interruption. Lowfrequency current is limited through the transformer eliminating low frequencysaturation. Automatic Saturation Compensation allows many speakers to be runon a distributed line with a 50Hz Hi-Pass filter before the amplifier, regardless of thenumber of speakers on the same line (the number of tapped watts cannot exceedthe amplifier rating). With the same 50Hz Hi-Pass, 10 speakers on transformerswill have the same full sound as a single speaker at 8 ohms.

˚ x 50˚ coverage for longer throw andcluster applications, 100˚ ˚many distributed audio applications. An added benefit is horn rotation, allowing theZX1i to be oriented either horizontally or vertically for complete coverage flexibility.

The ZX1i molded polymer enclosure is inherently water resistant. The addition of amultilayer grille with hydrophobic cloth and weatherized components enable theZX1i to perform under many environmental conditions. An optional weatherizedinput panel cover with a gland nut is available for additional protection.

The ZX1i’. sophis-

ticated crossover network integrates it with the DH2005, a 1-inch voice coil truecompression driver maximum output with extended frequency response. Full-bandwidth overload protection is provided for reliable, long term operation withoutaudible effect. 1 Half Space Measurement.

QuickSAM™ (Strong-Arm-Mount™) SystemZx1i™s QuickSAM™ system (Strong-Arm-Mount™) excels at meeting the four importantrequirements for mounting speaker systems: simple, quick, versatile, and reliable. Threeeasy steps and you are done: Securely attach the surface bracket to the wall or ceiling,click the Zx1i™ enclosure onto the bracket, aim the enclosure and tighten both bolts.

WARNING: Bolt “B” in Figure 2 must be tightened. Failure totighten Bolt “B” may allow the speaker to disengage from theQuickSAMTM Bracket, possibly resulting in serious injury.


Step-by-Step Installation and WiringStep 1: Mount the SAM™ Bracket to Mounting Surface

70°

90°

Figure 3: Vertical Mounting Figure 4: Horizontal Mounting

Figure 5: 70° Rotation Range Figure 6: 90° Sweep Range

WARNING: It is the installer’s responsibility to ensure that themounting surface is stable and can support more than thespeaker’s weight!

Use only industry-accepted fasteners and mounting methods when mounting thebracket. Consult an expert if you are not sure. Read steps 2 and 3 before attaching thespeaker in step 4. For standard vertical installation mount the SAM™ bracket as shownin Figure 3. For horizontal mounting configurations, mounting the bracket on the bottomside (as in Figure 4) is easiest, allowing the speaker to be mounted closer to the ceiling.


Step 2: Select Voltage Tap (Zx1i-90T and Zx1i-100T models only)Before attaching the speaker to the bracket, select the proper voltage tap setting for yourinstallation. The voltage selector switch is located at the rear of the speaker below theinput terminal panel. The power taps are 100, 50, 25W and 12.5W at both 70.7V and100V, with a 6W tap for 70.7V only. There is also an 8 ohm bypass setting. The taps areselected by a rotary switch on the back panel. A guide on the back of each speakershows which switch positions to use for the power settings at 70V and 100V. Figure 7below illustrates the settings.

Step 3: Select the horn dispersion orientation– If necessaryFor the 90° x 50° horn version you may elect to rotate the horn assembly for moreeffective coverage depending on the orientation of the speaker cabinet in yourinstallation. The horn is factory-installed with the 90° coverage in the horizontal planeand the 50° coverage in the vertical plane as shown in Figure 8 below.

To rotate the horn follow the steps below:

1. Remove the logo badge to expose grille mounting screws.2. Remove the grille assembly – see illustration3. Remove the screws holding the horn assembly in place. – see illustration4. Rotate the horn assembly 90°.5. Secure the horn assembly back to the baffle with the horn mounting screws.6. Secure the grille assembly to the baffle with grille mounting screws.7. Secure the logo badge back onto the grille.

Step 4: Attach the Speaker to the QuickSAM™ BracketAfter mounting the QuickSAMTM bracket (from Step 1) to the desired surface, attach thespeaker to the QuickSAMTM bracket by inserting the QuickSAMTM into slot on the side ofthe speaker until it “clicks” in place. Using the provided mounting tool, tighten the twosocket head bolts A and B enough to allow aiming, as shown in Figure 9. After selectingthe proper horizontal angle, secure the sweep axis as shown by tightening bolt A. Next,select the proper vertical angle and secure the rotation axis by tightening bolt B. Totighten the recessed bolt B, insert mounting tool through hole on the side of the speaker.

WARNING: Bolt “B” is what secures the speaker to theQuickSAMTM Bracket. It is the installer’s responsibility toensure that Bolt “B” is fully tightened. Failure to tighten Bolt“B” may allow the speaker to disengage from theQuickSAMTM Bracket, possibly resulting in serious injury. Useof the Seismic restraint is highly recommended. See Step 6.


Step 5: Wire the SpeakerConnect the wires to the speaker using the detachable 4 pole phoenix connector asillustrated in Figure 10. The 4 connections allow for convenient loop through wiring tothe next speaker system wired in the system.

Step 6: Secure the Seismic Tab Connection PointThe rear of the enclosure includes an eyebolt for connection to a seismic restraint.Connect it to a properly rated hardware fitting that is securely installed independently ofthe SAM™ bracket. Maintain a 12” (305mm) maximum length of slack or less. Even ifyour local construction code does not require the installation of secondary support, itsuse is highly recommended as additional security.

Step 7: Test System OperationAfter all connections are made, test the complete system operation. Appendix A (page10) contains a troubleshooting table to assist in locating many speaker-relatedproblems.

MaintenanceYour Zx1™ system has been designed and manufactured to provide years of durabilityand reliable service. No routine maintenance is necessary. Units may be cleaned bywiping with a soft, damp cloth. Never use solvents or harsh cleaning agents of any kind.

Appendix B: Painting the Zx1™ SpeakersPainting ProcessThe Zx1™ is made of high-impact polystyrene, which accepts a wide variety of paints.

· Remove the grille and mask the baffle.· Clean the cabinet and grille by rubbing the speaker with a lightly dampened

cloth. Do not, however, use abrasives such as sandpaper or steel wool. Neveruse gasoline, kerosene, acetone, MEK, paint thinner, harsh detergents, orother chemicals, as these agents may cause permanent damage to theenclosure.

· After cleaning, apply latex or enamel paint. Spraying is recommended

Painting the GrillePainting the grille requires spray painting. If the grille is rolled or brush painted, the meshmay become clogged with paint and poor sound quality may result.
