Troubleshooting Tips
Things to remember
Unshielded cables, improperly wired connectors, and cables with broken strands of wire are very common
problems. Use quality cables with quality, correctly wired connectors.
When using heavy compression, background noise is noticeable during quiet sections of the program as defined
in the section on compression, quiet program material is effectively made louder while loud peaks are made
quieter. When the program source is thus raised in volume, its noise floor is also raised in volume by a
proportionate amount. This is not a defect in the Compressor/Limiter, but an unavoidable side effect of the gain
altering process. If the noise becomes a problem, the solutions are to either decrease noise at the program
source, or use less compression.
No Output
Check AC power. Is the power switch on? Check input and output connections - are they reversed? Are you sure
you have an input signal?
Controls Have No Effect
Is the limiter In/Out switch In? Perhaps the ratio control is set too low to produce an audible effect or the input
level is below threshold. Is the threshold LED lighting up? If not, lower the threshold setting or increase the gain.
Do not expect to hear any effect when the input level is below threshold, since the unit is simply a linear amplifier
at those levels.
Excessive Hum or Noise
Hum is often caused by a "ground loop" between components. Try using the suggested balanced input and output
hookups if the other pieces of equipment used in conjunction with the CLG-600 unit have balanced inputs and
outputs. Noise can also be caused by insufficient drive levels. Make sure you are sending a nominal 0 dBV line
level signal to the unit.
