CABLE CONNECTIONS

This range of speakers features NL4 loudspeaker connectors. These connectors are hooked in a parallel "loop-
through" configuration for connection to additional speakers. For optimum performance it's important to use cables
specifically designed for speaker use. Do not use shielded "guitar" signal cables for connection to these speakers.
Selection of the appropriate wire gauge is important for system operation. A cable that is too light will result in
amplifier power being wasted due to the series resistance of the cable. In addition, loss of low-frequency
performance may be experienced due to a degraded damping factor.
TROUBLESHOOTING
One certain method of determining if a speaker is faulty is to substitute a speaker that is known to work correctly for
the suspected problem speaker. If the "normally correct speaker" is experiencing the same difficulties or problems
as the suspected problem speaker, use the information below to isolate the problem.
No output
Possible cause
Speaker cables
Amplifier
Intermittent
Possible cause
Poor connections
Constant noise, buzzing and/or humming
Possible cause
Faulty electronic
Poor low-frequency output
Possible cause
Improper polarity
Action
Reseat all connectors
Substitute known good speaker cables
Check solder joins
Tighten NL4 connectors
Inspect cable for damage
Inspect wire or connector for stray strand that may short
Make sure the amplifier channel is being fed a signal. Most amps have a "signal input" LED
to indicate the presence of a signal. Re-patch the speaker to an amplifier channel that is
known to work.
Action
While it is possible for a faulty speaker to exhibit intermittent output, it's more likely that an
output cable/connector is the problem. Check the soldering on your connectors.
Action
Any constant noise originates in the amplifier, mixer, signal processing, source device in
the signal devices, or line-level wiring. Check and correct system grounding as required.
Chain check for noisy sources or electronic components. Check wiring for shielding.
Action
When two speakers in close proximity to each other are connected out-of-polarity, they can
partially cancel each other out, especially at low frequencies. Check your speaker cables to
be sure they are all identically wired and connected. Check the balanced line signal cables
to be sure they are all correctly wired.
