Mackie DL806 and DL1608 Reference Guide Reverb Sliders The following is a list of sliders available for each selected reverb. Slide left to decrease the reverb time and slide right to increase the reverb time. Pre Delay (All) - When listening to a live performance, direct sounds are reached first, followed by reverberation caused by room reflections. The pre delay is the amount of time between when the direct sounds arrive and when the reflections arrive. The range is 0 ms to 300 ms. The speed of sound is approximately 340 meters per second (1100 feet per second). This means that in one millisecond, it travels 0.34 meters (110 feet). As a rough idea, think of 1 ms as the time it takes for sound to travel one foot. Damping (All) - Damping increases or decreases the decay time of the higher frequencies relative to the overall decay time. That is, the amount of sound reflections that make up the reverb. Lower values sound "thinner," while higher values give a smoother-sounding decay. The range is 500 Hz to 20 kHz. Decay (All) - This represents the decay time of the reverb. The range will vary depending on the reverb chosen. Rolloff (All except Gated Reverb) - This provides a 24 dB/octave low-pass filter at the output of the reverb. This allows the level of the audio range to be rolled off above the frequency set by this slider. The range is 500 Hz to 20 kHz. Release (Gated Reverb) - Release is the amount of time it takes for attenuation to happen. The range is 50 ms to 3000 ms. Parameter Pre Delay Damping Decay Rolloff Release Low Value 0 ms 500 Hz 0.1 s - 4.0 s 500 Hz 50 ms High Value 300 ms 20 kHz 1.3 s - 10.0 s 20 kHz 3000 ms Default 0 ms 20 kHz 2.00 s 20 kHz 250 ms 74
