6 - Using the Settings Panel COMPRESSOR display area overview When the input volume exceeds the THRESHOLD level, the input volume is compressed, reducing output volume variation. For example, by reducing the levels of sounds that are high level, lower level sounds become relatively louder, creating a more even volume level throughout and a more sustained sound. REVERB display area overview This effect adds reverberations to the original sound. Multiple sounds are delayed at various times with damping over time that is as natural as possible to produce reverberations like those of a hall, live-music club or studio, for example. 1 Compressor status display Three meters show the level of the signal input to the compressor (INPUT), the level of the signal output from the compressor (OUTPUT) and the gain reduction caused by the compressor (GR). 2 THRESHOLD knob Sets the threshold level that will cause the compressor to start. Range: −32 dB - 0 dB (default: 0 dB) 3 RATIO knob Sets the compression ratio for the input volume. Turning it right raises the compression ratio, increasing the amount of compression. Range: 1.0:1 - inf:1 (default: 1.0:1) 4 GAIN knob Sets the gain of the output signal. When the volume is compressed, the output level becomes lower than the input level. Use the GAIN knob to increase the output level so that it is close to the input level. Range: 0 dB - 20 dB (default: 0 dB) 5 ATTACK knob Sets the amount of time until the compression reaches the compression RATIO setting after the input volume exceeds the threshold. Range: 2 ms - 200 ms (default: 2 ms) 6 RELEASE knob Sets the amount of time until the compression stops and the sound returns to its uncompressed level after the input sound goes below the threshold. Range: 10 ms - 1000 ms (default: 10 ms) NOTE • If the input is a stereo signal (stereo-linked channel or master), compression will start and be applied to both channels when either the left or right input channel exceeds the threshold level. • When the compressor is off, the compressor curve will appear but the meters will not be active. 1 Reverb status display This shows the setting status of the PRE DELAY and REVERB TIME knobs. 2 Reverb type switch Use to select the type of reverb. Depending on the type, the density and level of the reverb sound changes. Options: HALL (default), ROOM, LIVE, STUDIO, PLATE 3 PRE DELAY knob Set the amount of delay until the first reverberations. The larger the value, the larger the reverberations make the room sound. Range: 0 ms - 250 ms (default: 90 ms) 4 REVERB TIME knob Set the amount of time that the reverberations continue. The larger the value, the longer they continue. Range: 0.1 s - 10 s (default: 2.7 s) 5 DIFFUSION knob Sets the breadth of the reverberations. Range: 0 - 100 (default: 20) TASCAM US-20x20 19
