Model Summary
All four Zx1i models use an 8-inch high-
excursion LF driver and a 1-inch exit
titanium compression driver on a
rotatable horn to provide high-fidelity, full-
range sound over a wide coverage area.
The system also features the exclusive
QuickSAMTM mounting system for easy
mounting and aiming.

ZX1iis thenewstandard ofnocompromiseaudio performance
andversatility in an easy to install, compact sound reinforcement package.
Thehigh-techenclosure usesinjection-moldedhigh-impact polypropylenetomake
theZX1i extremely durable. The enclosure geometry has been engineered to
providemaximum rigidity and acoustic performance. The velocity compensated
portdesign overcomes the limitation of many small cabinet loudspeakers and
enablesexceptional low-frequency response without vent noise.
ZX1iinstallation is incredibly simple with the included QuickSAM
TM
mounting sys-
tem. The QuickSAM
TM
is a unique, integrated mounting bracket which is virtually
foolproof. It allows the installer to simply snap the speaker onto the bracket, then
tightenit to the desired position. Forarray mounting, there is an optional array
bracketkitavailable whichallowsmultiple unitstobemounted togetherfora variety

QuickSAM™ (Strong-Arm-Mount™) System
Zx1i™s QuickSAM™ system (Strong-Arm-Mount™) excels at meeting the four important
requirements for mounting speaker systems: simple, quick, versatile, and reliable. Three
easy 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 to
tighten Bolt “B” may allow the speaker to disengage from the
QuickSAMTM Bracket, possibly resulting in serious injury.

Step-by-Step Installation andWiring
Step 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 the
mounting surface is stable and can support more than the
speaker’s weight!
Use only industry-accepted fasteners and mounting methods when mounting the
bracket. Consult an expert if you are not sure. Read steps 2 and 3 before attaching the
speaker in step 4. For standard vertical installation mount the SAM™ bracket as shown
in Figure 3. For horizontal mounting configurations, mounting the bracket on the bottom
side (as in Figure 4) is easiest, allowing the speaker to be mounted closer to the ceiling.

6 Electro-Voice®Zx1i Owner’s Manual
Step 2: SelectVoltageTap (Zx1i-90T and Zx1i-100T models only)
Before attaching the speaker to the bracket, select the proper voltage tap setting for your
installation. The voltage selector switch is located at the rear of the speaker below the
input terminal panel. The power taps are 100, 50, 25W and 12.5W at both 70.7V and
100V, with a 6W tap for 70.7V only. There is also an 8 ohm bypass setting. The taps are
selected by a rotary switch on the back panel. A guide on the back of each speaker
shows which switch positions to use for the power settings at 70V and 100V. Figure 7
below illustrates the settings.

Step 3: Select the horn dispersion orientation– If necessary
For the 90° x 50° horn version you may elect to rotate the horn assembly for more
effective coverage depending on the orientation of the speaker cabinet in your
installation. The horn is factory-installed with the 90° coverage in the horizontal plane
and 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 illustration
3. Remove the screws holding the horn assembly in place. – see illustration
4. 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™ Bracket
After mounting the QuickSAMTM bracket (from Step 1) to the desired surface, attach the
speaker to the QuickSAMTM bracket by inserting the QuickSAMTM into slot on the side of
the speaker until it “clicks” in place. Using the provided mounting tool, tighten the two
socket head bolts A and B enough to allow aiming, as shown in Figure 9. After selecting
the 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. To
tighten the recessed bolt B, insert mounting tool through hole on the side of the speaker.

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

Electro-Voice®Zx1i Owner’s Manual 9
Step 5:Wire the Speaker
Connect the wires to the speaker using the detachable 4 pole phoenix connector as
illustrated in Figure 10. The 4 connections allow for convenient loop through wiring to
the next speaker system wired in the system.
Step 6: Secure the SeismicTab Connection Point
The 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 of
the SAM™ bracket. Maintain a 12” (305mm) maximum length of slack or less. Even if
your local construction code does not require the installation of secondary support, its
use is highly recommended as additional security.
Step 7:Test System Operation
After all connections are made, test the complete system operation. Appendix A (page
10) contains a troubleshooting table to assist in locating many speaker-related
problems.
Maintenance
Your Zx1™ system has been designed and manufactured to provide years of durability
and reliable service. No routine maintenance is necessary. Units may be cleaned by
wiping with a soft, damp cloth. Never use solvents or harsh cleaning agents of any kind.

Appendix B: Painting the Zx1™ Speakers
Painting Process
The 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. Never
use gasoline, kerosene, acetone, MEK, paint thinner, harsh detergents, or
other chemicals, as these agents may cause permanent damage to the
enclosure.
· After cleaning, apply latex or enamel paint. Spraying is recommended
Painting the Grille
Painting the grille requires spray painting. If the grille is rolled or brush painted, the mesh
may become clogged with paint and poor sound quality may result.
