Tripod
Electro-Voice ZxA1 speakers include 35 mm (1-3/8 inch) stand mounts to allow mounting on tripod stands. Make sure to:
•
•
•
•
•
•
•
Check the specifications of the speaker stand to be certain it is capable of supporting the weight of the speaker.
Check the speaker stand is placed on a flat, stable surface and fully extend the legs of the
stand. Do not try to make the stand “taller” and compromise its structural integrity.
Route cables and position the stand so performers, production crew and audience
members will not trip over the stand or cables and pull the speaker system over.
Secure cables with wire ties or tape whenever possible.
Do not attempt to suspend more than one speaker on a stand designed for a single speaker.
Unless you are confident you can safely handle lifting the weight of the speaker
onto the stand, ask another person to help you place it.
Tighten the set screw to minimize rattling and to prevent the speaker from rotating during use.
Pole Mount
Electro-Voice ZxA1-Sub speakers include 35 mm (1-3/8 inch) pole mount cups to allow mounting a full range speaker above it.
Make sure to:
•
•
Use a speaker pole that is no longer than 1.2 m (4 ft) and mount a speaker weighing no more than 11.3 kg (25 lb).
Check that the ZxA1-SUB is placed on a flat and stable surface.
No more than
11.3 kg (25 lb).

Suspending ZxA1 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 seperately). 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.

ZxA1 Amplifier Controls
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.
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 highpass 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.
MAINS IN
AC connection is established via an IEC-connector. A 10 ft (3 m) long AC cord with fitting
IEC-plug is supplied. Locking IEC power cords may also be used.

Troubleshooting
Problem
1. No Sound
Possible Cause(s)
Action
Amplifier
Connect a known working signal source to the amplifier inputs. If
there is no sound, check all the electronics are on, the signal routing
is correct, the source is active, the volume is turned up, and so on. If
there is sound, the problem is in the wiring, or a component further
up the signal chain.
Wiring
Verify 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.
2a. Poor Low-Frequency
Response with ZxA1
WITH SUB switch
activated
Set the FULL RANGE/WITH SUB switch to the FULL RANGE
position.
2b. Poor Low-Frequency
Response with ZxA1-Sub
Incorrect polarity
Set the NORMAL/REVERSE POLARITY to the opposite position.
3. Intermittent output
such as crackling
or distortion
Faulty connection or
damaged cable
Check all connections in the signal chain to ensure they are clean
and tight. If the problem persists, it may be in the amplifier or wiring.
See Problem 1.
4. Constant noise
such as buzzing,
hissing, humming
Defective source
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.
Incorrect gain structure
Verify level controls of the source are properly structured. Verify
microphone cables are plugged into MIC IN and line level cables are
plugged into LINE IN.
5. No sound produced
with microphone
connected to MIC IN
Microphone requires
phantom power
Use a dynamic microphone that does not require phantom power.
If using a microphone that requires phantom power, an external
phantom power source will be needed.
6. Sound is distorted.
LIMIT LED is constantly on
or flashing regularly
Excessive input level
Reduce the Master Level or loudspeaker level knobs to prevent limit.
Line level source
plugged into MIC IN
Plug line level source into LINE IN
7. Sound is distorted.
LIMIT LED is not blinking
Source input (mixing
console/preamp) is
overdriven
Verify level controls of the source are properly structured.
8. Microphone produces
acoustic feedback when
input level is amplified.
Incorrect gain structure
Reduce the microphone levels at the mixing console or input source. If
the microphone is connected directly to the speaker reduce the MIC
LEVEL on the speaker. Positioning the microphone close to the sound
source will increase gain-before-feedback.
Microphone position is
too close to the front of
the speaker
Whenever possible setup the speakers so the microphone is behind
them. If using the speakers in a monitor position aim the speaker to the
back of the microphone.
If these suggestions do not solve your problem, contact your nearest Electro-Voice dealer or distributor.
