COMP switch - turns the compressor on. The LED lights when active. COMPRESSION METER - 4-Led bargraph indicates the amount of gain reduction in dB, which is taking place at any given moment. RELEASE - sets the time during which the signal returns to its normal size after compression.

Turning the COMPRESS control clockwise lowers the compression threshold, and drives the compressor harder. Variable Ratio In the Joemeek optical compressor the compression ‘threshold’ is not clearly defined and the compression ratio varies with the amount of compression applied.

It also goes right down to nothing and so acts as a fader to fade a sound out completely. Output Stage Another application is in a simple live performance setup. For example one threeQ could process a vocal while a second processed a guitar. The two signals would then be mixed before feeding a PA slave amplifier.
three q manual.indd 14-15 3/9/04, 4:19 PM 13 12 Always start with the Meequalizer boost/cut controls (LF, MID and HF) set to “0” (the control knobs set vertically, in their centre notches). This setting is also known as “flat”. Using the Meequalizer Use the ‘COMP’ switch to make comparisons between compressed and uncompressed signals. The overall result of compression depends on the combined settings of the Input and Output Gain, Compress, Attack and Release controls.
