Compressor

Compression is a tool that sets boundaries for the strength of your guitars signal. A bi-product of containing a signal within these boundaries is long lasting sustain, as well as a tight, smooth texture. Selecting the Compressor is done by pressing the Preamp button until the Compressor module is flashing in the display. The display will look something like this:

L/R OUTS

1.This is showing that the type of effect you are about to edit is a Compressor, and that the effect is on. The number 1 icon before the word “on” indicates that in order to access the on/off parameter, you need to press the number 1 button. The status can then be changed by rotating the Data Wheel.

2.This is the default setting for the Compressor. The Compressor default shown here is factory default 5 (F5)which is a heavy Compression setting. The number 4 which precedes the F5 value, indicates that in order to access the default parameter, you must press the number 4 button. The default can then be changed by rotating the Data Wheel. See page 22 for a complete list of defaults.

3.The bottom corner of the display is showing that there are 3 pages of parameters associated with the Compressor, and that you are on the first of these three pages. The next and previous page button can be used to access the other pages of parameters associated with the Compressor.

When you access page two of the compression parameters, the display will look something like this:

The display it now telling you four more things about the Compressor parameters

1.This is the Compressors Threshold parameter. The Threshold is the strength the incoming signal must be before the compression will start. A signal above this level will be compressed, a signal below this level will not. The number 1 icon is telling you that in order to access the Threshold parameter, you must press the number 1 button. Then you can adjust the Threshold value by rotating the Data Wheel.

2.This is the Compressors Ratio parameter. The Ratio is the amount of compression that will be applied to the signal once the Threshold has been exceeded. In the display shown above, the Ratio is 9 to 1 (the 1 is implied). A Ratio of 9 to 1 means that for every 9 dB of incoming signal, there will only be a 1 dB increase in output. The number 2 icon is telling you that in order to access the Ratio parameter, you must press the number 2 button. Then you can adjust the Ratio value by rotating the Data Wheel.
