Appendix D: Troubleshooting Guide

Problem

Possible Cause(s)

Action

1. No sound

Amplifier

Verify that that the line level signal cable’s

 

 

XLR connector has been pushed all the way

 

 

into the ‘Low Level In’ jack on the amplifier

 

 

panel. Turn the ‘Power’ switch on and the

 

 

volume up until you can hear sound emitting

 

 

from the 12.1p subwoofer. If there is still no

 

 

sound, the problem is with the line level

 

 

signal.

 

Line level signal

Connect a known working powered test

 

 

speaker to the line level signal from the

 

 

mixer, pre amplifier or other source. If there

 

 

is no sound, check that all of the electronics

 

 

are on, the signal routing is correct, the

 

 

source is active, the volume is on and so on.

 

Fuse

Carefully remove the fuse holder from the

 

 

power cord input with the use of a flat head

 

 

screwdriver. Inspect the fuse for any

 

 

damage. Blown fuses will typically show a

 

 

smoke-like blackening on the inside of the

 

 

glass. If this is the problem, replace the fuse

 

 

with a 4A/250V, 20mm x 5mm fuse.

 

 

Only replace this fuse with the same type

 

 

and rated fuse to reduce the risk of fire.

2. Poor low-frequency

Speakers wired

When two speakers are connected out

response

out-of-polarity

of polarity (out of phase), the low frequencies

 

 

will cancel each other acoustically. Carefully

 

 

observe the wire markings or tracers on your

 

 

full-range speaker wires. Verify that their

 

 

amplifier (+) terminal is connected to the red

 

 

speaker terminals and their amplifier (-)

 

 

terminal is connected to the black speaker

 

 

terminals.

3. Intermittent output

Faulty

Check the low-level signal cable/XLR

such as crackling or

connection/wiring

connector to make sure that it has been

distortion

 

pushed all the way into the ‘Low Level In’

 

 

amplifier panel jack. If crackling persists,

 

 

remove the signal cable from the amplifier

 

 

and its low-level signal source and check for

 

 

a faulty connection between the connector

 

 

and the cable. Make sure that all of the

 

 

terminals on cable connectors have been

 

 

properly soldered.

If these suggestions do not solve your problem, contact your nearest Electro-Voice

 

dealer or Electro-Voice distributor.
