Compression value of 0 1 or lower see COMPRESSION below the Target Level acts as the equator line beats above it will increase in gain while beats below it will decrease in gain effectively increasing the dynamic range COMPRESSION Sets the amount of gain applied to each beat toward the Target Level Set Compression to any value between 0 1 to 100 for dynamics compression or to a value between 0 1 to 100 for dynamics expansion For example if the Compression is set to 100 and the Target Level is set to 12dB any beat within the Thresholds will be adjusted to a peak level of 12dB Similarly if the Compression is set to 50 a 6dB beat will be decreased to 9dB and a 18dB beat will be increased to 15dB In expansion mode setting Compression to 100 will augment a 6dB measured beat above the Target Level to 12dB above it and a beat measured at 6dB dB below the Target Level will be further reduced to 12dB below it Similar to the main display window the Compression Expansion Meter around the Compression dial displays gain boost in orange and gain reduction in light blue MIN RETRIGGER TIME Sets the minimum time for Drum Leveler to consider a new beat after a beat was detected 2015 Sound Radix Ltd All Rights Reserved GAIN RANGE Sets the maximum gain change Drum Leveler will apply to a beat within the set Thresholds For example if Compression is set to 50 and the maximum Gain Range is set to
