Old electrical and electronic equipment
This product and/or battery must be disposed of separately from household waste.
Dispose such equipment according to local laws and regulations, to allow their reuse
and/or recycling. This will help in conserving resources, and in protecting human
health and the environment.
1.2 FCC information
Changes or modifications not expressly approved by the party responsible for compliance
could void the user's authority to operate the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be required to correct the
interference at his own expense.
1.3 Precautions
!
If an Electro-Voice loudspeaker is used outdoors on a sunny day, place the
loudspeaker in a shaded or covered area. The loudspeaker amplifiers have
protection circuits that temporarily shut the loudspeaker off when extremely
high temperatures are reached. This can happen on hot days when the
loudspeaker is in direct sunlight.
!
Do not use Electro-Voice loudspeakers in an environment where temperatures
are below 0°C (32°F) or exceed +35°C (95°F).
!
Never expose an Electro-Voice loudspeaker to rain, water, or high moisture.
!
Electro-Voice loudspeakers are easily capable of generating sound pressure
levels sufficient to cause permanent hearing damage to anyone within normal
coverage distance. Caution should be taken to avoid prolonged exposure to
sound pressure levels exceeding 90 dB.

3.2 Suspending the loudspeakers
Electro-Voice ZXA1 loudspeakers may be safely suspended with single stud fittings by using
the MP1 suspension kit, or quickly attached to a truss by using the CA-Zx truss clamp adaptor
(both sold separately). See MP1 or CA-Zx instruction sheets for proper assembly and use.
!
Warning!
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 ZXA1 speakers be suspended taking into account all
current national, federal, state, and local regulations. It is the responsibility of the installer to
ensure that ZXA1 speakers are safely installed in accordance with all such regulations. If ZXA1
speakers are suspended, Electro-Voice strongly recommends that the system be inspected at
least once a year. If any sign of weakness or damage is detected, remedial action should be
taken immediately. There are instruction sheets for each EV Suspension and Array Kit that
should also be consulted prior to suspending speakers.

3.4 Rotating the logo
All versions of the ZXA1 (except the ZXA1-SUB) allow for the logo to be rotated, if required.
The logo badge is square and can be rotated in 90° increments.
To rotate the logo badge:
1. Using a finger or flat-edge screwdriver (using care not to scratch grille), grip under the
logo badge.
2. Pull the logo badge outwards from the logo recess until it fully clears the front surface of
the grille.
3. Rotate the logo badge, in 90° increments, to the desired orientation.
4. Release the logo badge and let it “spring” back into the logo recess.

4 Amplifier controls
Figure4.1: ZXA1 and ZXA1-SUB amplifier panels
Control Function
LIMIT
The LED brief blinking indicates the power
amplifier is operated at its limits. Short-term
blinking is not critical because the integrated
limiter keeps distortion under control.
Constant lighting of the LED indicates the
sound is negatively affected. Reducing the
output volume is strongly recommended.

14 en | Amplifier controls ZXA1 Series Loudspeaker
2022-06 | 06 | F.01U.218.487 User manual Electro-Voice
Control Function
MASTER
Level control for adjusting the power amp’s
overall amplification. The level control affects
the volume of the line input and microphone
input. To prevent distortion and clipping of
pre-linked mixing consoles, the control
should generally be set to a value between
0dB and +6dB.
MIC
Level control for adjusting the microphone
input level independent of the master level.
MIC IN
XLR input for low level signals like
microphones. The MIC IN and LINE IN may
both be used at the same time as a 2-channel
mixer.
WITH SUB/FULL RANGE
When depressed, activates a 100Hz high
pass for use with a subwoofer, or if the ZxA1
is used as a floor monitor. A pen or paperclip
is needed to depress the switch to WITH SUB
mode.
LINE IN
Electronically balanced input for the
connection of high-level signal sources like
mixing consoles or signal processors.
Connections can be established using 1/4-
inch TRS or XLR-type connectors.
MASTER OUT
Output connector to send the signal to
another speaker or subwoofer. The output is
the sum of both the MIC IN and LINE IN.
POWER
AC switch for switching the ZxA1’s power ON
or OFF. The LED lights after turning the
power ON. If the LED is not lit upon turning
the power on, make sure the AC cord is
correctly connected and the outlet is properly
working.

fitting IEC-plug is supplied. Locking IEC

limiter keeps distortion under control.
Constant lighting of the LED indicates the
sound is negatively affected. Reducing the
output volume is strongly recommended.
LEVEL
Level control for adjusting the volume of the
subwoofer. The level control affects the
volume of both Channels A and B.
BOOST
The BOOST switch controls the low-
frequency extension of the subwoofer.
NORMAL works best when the subwoofer is
used under normal applications. LOW-END
BOOST provides additional low-frequency
extension and works best for applications
requiring enhanced bass performance.
POLARITY
The POLARITY switch controls the acoustic
polarity of the subwoofer. When using with a
ZxA1 and in most applications, the switch
should always be set to NORMAL. If the bass
output is low when using with other
loudspeaker systems and subwoofers, try
setting the switch to REVERSE POLARITY.
XLR INPUT
XLR input connector to receive the signal
from another speaker or subwoofer.
