8 Troubleshooting
Problem Possible Cause(s) Action
1. No sound Improper gain Verify all the sources are on. If the source is a condenser
microphone, make sure the mic is plugged into INPUT1
via XLR and phantom power is enabled in the menu.
Inspect the VU meters on LCD or in the app. If there is
signal present on the VU meters, increase the input and
gain controls to the required level. If there is no signal
present on the VU meters, then check the wiring.
Sources not
connected
Check all cables between the source and the
loudspeaker with a multimeter or cable tester. Replace
any suspect cables with a known good cable.
2. Poor Low-
Frequency
Response
With SUB menu
cross-over frequency
activated
If no subwoofers are used with the system, select the
OFF position.
SPEECH mode is
active
In the DSP control menu, change the MODE to MUSIC,
LIVE, or CLUB. Refer to
DSP controls, page 34
for more
details.
Input PRESET is not
set to FLAT
In the INPUT DSP control menu, change PRESET to
FLAT. Refer to
INPUT DSP control menu, page 46
for
more details.
EQ is active In the INPUT and DSP control menu, reset all EQs in the
low frequencies. Refer to
DSP controls, page 34
and
INPUT DSP control menu, page 46
for more details.
3. Intermittent output
such as cracking or
distortion
Faulty connection Check all connections at loudspeaker to ensure they are
all clean and tight. If the problem persists, check the
wiring. See problem 1.
4. Constant noise
such as buzzing,
hissing or humming
Defective source or
other electronic
device
If noise is present, but no program material is playing,
evaluate each component as necessary to isolate the
problem. Most likely there is a break in the signal path.
Poor system
grounding or ground
loop
Check and correct the system grounding, as required.
Input gain is not at a
microphone level.
Slowly increase the INPUTLEVEL to engage the
microphone pre-amp.
Mobile device is
connected via USB
and 3.5mm jack
simultaneously.
Some mobile devices, such as laptops and mobile
phones, may introduce ground loops if the loudspeaker is
charging the mobile device while simultaneously
connected via the 3.5mm audio input jack. Connect the
audio via Bluetooth®, or disconnect from the USB jack.
