Compressing  A significant difference in dynamic range is achieved simply by changing the 

relationship between nominal signal level and threshold, as a result of either 

increasing the GAIN and/or decreasing the TRESHOLD control. The most interesting 

effect to be noted, however, is seen by comparing the original input signal with the 

output signal. The quietest portions of the original signal will be effectively increased in 

volume while the loudest portions of the original signal will be decreased. In effect, 

both ends of the dynamic spectrum will be pushed toward the ‘middle’. More than 

anything else, it is this double-ended effect, which distinguishes compressing from 

limiting. 

 

3.  Connectors & Cables 

 

The unit has three different connector types: 

 

¼‘‘ stereo TRS jacks 

 

3-Pin XLR 

 

Euroblocks 

 

These three connectors facilitate interfacing to most professional audio products. Both inputs and 

outputs can be used balanced or unbalanced. 

 

 

 

If you must use unbalanced connectors, the negative lead of the connector should be tied to the 

ground lead. Using unbalanced connections could result in chassis ground-loop noise. Altering the 

signal/chassis ground relationship in equipment connected to your unit may eliminate the noise.
