Expander
10.Threshold determines the level below which gain reduction will take place, variable from 20dBu down to
11.Ratio sets the degree of expansion applied below the threshold level, variable from 1:1 to 25:1. A ratio of 1:1 corresponds to zero expansion : Signal In = Signal Out. A ratio of 10:1 indicates that when the input signal, below the threshold, falls in level by 1dB, the output level will fall 10dB.
12.Release determines the time taken for the gain to return to normal after the signal comes back above the threshold level, adjustable from 40 milliseconds to 2 seconds.
13.ATK (Attack) is a switched control offering either automatic
14.Gain is the output level control for the entire channel, Compressor, Expander and Limiter. The output level light bar graph meter indicates OUTPUT level when the channel is switched in circuit. When the channel is bypassed, the meter indicates INPUT level.
15.EXP In selects the expansion effect to be in or out.
Limiter
16, Threshold sets the level above which the signal will be limited (compressed at a high 25:1 ratio), adjustable from 0dBu to 20dBu.
17.Clipper In selects peak clipping. Clipping totally eliminates transient peaks, effectively acting as a limiter with an infinity:1 ratio and an instantaneous attack time. The Clipper threshold follows the Limiter threshold as set.
18.Power switches mains power on or off.
