TROUBLESHOOTING
PASSIVE VERSION
Problem: No sound coming from the speaker
Action to Solution:
- Check volume levels on the amplier and signal sources and
the connections between them. If your amplier has signal
detection or measuring visuals, test if it is reacting to the
signal source. If everything seems to be ok, connect another
speaker known to be working to the amplier. If it works, the
wiring to the Pro Speaker may have problems.
- Check that you have the correct pair of wires connected to
the speakers you are trying to work with. Look for signs of
damage if possible and check that the wires are correctly
mounted on the connector and the connecter is correctly
inserted on the speaker.
Problem: Little to no Bass
Action to Solution:
- This happens most of the times when two or more speakers
near each other, are wired out of polarity. In this case low
frequencies will cancel each other acoustically. Check that the
“+” on the amplier, is connected to the 1+ on the NL4 and
the “-“ marked on the amplier terminal is connected to the 1-
on the NL4.
ACTIVE VERSION
Problem: Buzzing, hissing or humming
Action to Solution:
- If there is noise and no program material is playing, check
your entire signal chain for the bad component. It can also be
a matter of poor grounding or a ground loop. Check and
correct the system grounding.
Problem: No sound from microphone on CH1
Action to Solution:
- Check if the microphone is a condenser one. If it is, change to
a dynamic one or use an external phantom power for
condenser microphones.
Problem: Sound is distorting with PEAK led OFF
Action to Solution:
- Reduce the level from the audio source, such as the mixer,
increase the level on the input potentiometer.
Problem: Sound is distorting with PEAK led mostly ON
Action to Solution:
- Reduce the level on the input or audio source
Problem: Too much low end when installed on wall or ceiling
Action to Solution:
- Due to wall and/or ceiling reections the bass response is
increased. To linearize the low end, select the Wall preset.
Problem: Poor high frequency response
Action to Solution:
- Probably the room is too absorbent or you are listening from
a long distance. To increase the HF frequency response, select
the HF Boost preset.
Problem: Poor low frequency response
Action to Solution:
- Probably the High-Pass Filter is enabled. Press and hold the
PRESET button for two seconds to disable de HPF.
