Thinking on Compressor (1) 

 

Keep in mind that a compressor, like any other piece of processing gear, will afford optimum results only if its operational level (+4 dBu or -10 dBu) is matched to the rest of your music system. Without a proper match, you may incur noise and/or distortion. VCAs (Voltage ControlledAmplifiers), which are the electronic heart of virtually all late-design compressors, are very finicky creatures. Too little as well as too much signal running their circuits can turn them into unhappy campers. If there is an unavoidable mismatch, you may have to use somewhat extreme threshold and/or compression settings in order to obtain the desired results. However, the situation can still be workable.

 

To help avoid exceeding a compressor's input and output limits, many devices allow you to meter these levels as well as the amount of "gain reduction" that is being applied to the incoming signal. If your compressor lacks input and output metering, then matching your operational levels becomes even more important. Consult your manual or a technically knowledgeable person. This will make a big difference.

 

As helpful as compressors can be, they can also aggravate a less than ideal situation. If you introduce a noisy source, such as a poorly recorded analog tape track into a compressor, then the problem will be exaggerated because the compressor will increase the average level of the noise relative to the source material. Understanding the general flow of signal through your music system and optimizing gain stages will aid you immeasurably in obtaining quality results from not only compressors, but from any piece of outboard processing gear you might be using.
