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