TheElectro-Voice ZX1i is the standard of no
compromiseaudio performance and versatility in an
easyto install compact package.
Thehigh-tech enclosure uses injection-molded
high-impactABS resin to make the ZX1i extremely
durable.The enclosure geometry has been engineered
toprovide maximum rigidity and acoustic
performance.The velocity compensated port design
overcomesthe limitation of many small cabinet
loudspeakersand enables exceptional low-frequency
response.Two rotatable horn coverage patterns are
available;90° x 50° for longer throw and cluster
applications,100° x 100° for broad even dispersion. A
multilayergrille with hydrophobic cloth and
weatherizedcomponents allows both indoor and
outdooruse. An optional weatherized input panel
coverwith a gland nut is available for additional
protection.
Installingthe ZX1i is quick and easy with the included
QuickSAMmounting system. The QuickSAM allows the
installerto simply snap the speaker onto the bracket,
andthen tighten it to the desired position. For array
mounting,there is an optional AB-ZE array bracket kit
whichallows multiple units to be mounted together in
avariety of configurations.
TheZX1i’s long excursion, high output 8 inch woofer
witha weatherized treated cone delivers smooth
low-frequencyperformance with exceptional reliability.
Asophisticated crossover network integrates it with
theDH2005, a 1.25 inch voice coil true compression
driverfor maximum output with extended frequency
response.Full-bandwidth overload protection is
providedfor reliable, long term operation without
audibleeffect.
Bestoverall system design practice always includes a
high-passfilter in the signal chain before the driving
amplifierto protect the loudspeaker from
over-excursionbelow box tuning or in the case of a
distributedconstant voltage installation, to protect the
drivingamplifier from the ill-effects of transformer
saturation.The ZX1i -T incorporates patented ASC
(AutomaticSaturation Compensation) technology to
preventtransformer saturation at low frequencies.
Unliketypical transformer equipped loudspeaker
systems,an installation of Electro-Voice ZX1i -T
loudspeakersdoes not require the high-pass filter
frequencyto be raised as more loudspeakers are
addedto the line because the driving amplifier is
protectedby ASC from saturation-induced overload,
distortion,and possible failure. Best of all,there is no
perceivabledifference in sound quality between
transformerand non-transformer versions of ZX1i
loudspeakers.The same 50 Hz high-pass filter is used
forboth, regardless of the number of loudspeakers on
theline.

ZX1i Series Loudspeaker Troubleshooting | en 15
Electro-Voice Installation Manual 2022-01 | 04 | F.01U.177.815
3 Troubleshooting
Problem Possible causes(s) Action
1 No sound Amplifier Connect a known working
test speaker to the amplifier
outputs. If there is no
sound, check that all the
electronics are on, the
signal routing is correct, the
source is active, the volume
is turned up, and so on.
Correct/repair/replace as
necessary. If there is sound,
the problem is in the wiring.
Wiring Verify that you have
connected the correct wire
pairs to the amplifier. Play
something at low level
through the amplifier (for
example, from a CD player
or tuner). Connect the test
speaker in parallel with the
malfunctioning line. If the
sound level has gone or is
very weak, the line has a
short in it (possibly a severe
scrape, pinch, or staple
puncture). If the sound level
is normal, the wire is open
(possibly a cut wire or a
missed connection). Using
the test speaker, move
down the line and test each
connection/junction until
you find the problem and
correct it. Observe proper
polarity.
2 Poor low-frequency
response
Speakers wired out-of-
polarity
When two speakers are
connected out of polarity
(out-of-phase), the low
frequencies will cancel each
other acoustically. Carefully
observe the wire markings
or tracers on your speaker
wires. Verify that the
amplifier (+) terminal is
connected to the red
speaker terminals and the

16 en | Troubleshooting ZX1i Series Loudspeaker
2022-01 | 04 | F.01U.177.815 Installation Manual Electro-Voice
Problem Possible causes(s) Action
amplifier (-) terminal is
connected to the black
speaker terminals.
3 Intermittent output such as
crackling or distortion
Faulty connection Check all connections at
amplifier and speakers to
ensure that they are all
clean and tight. If the
problem persists, it may be
in the amplifier or wiring.
Refer to Problem 1.
4 Constant noise such as
buzzing, hissing, humming
Defective amplifier or other
electronic device
If the noise is present but
no program material is
playing, the likely cause is
the signal chain in the
electronics. Evaluate each
component as necessary to
isolate the problem.
Poor system grounding or
ground loop
Check and correct the
system grounding, as
required.
If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or
Electro-Voice distributor.
