3 Compressor/Limiter RATIO When turned to 1:1, the compressor/limiter section is inactive. Turning the control clockwise increases the compression ratio, giving a true limiter at the fully clockwise position. The compressor normally has an ‘over-easy’ characteristic – pressing the button replaces this with a ‘hard knee’ characteristic, providing an alternative for some instruments.
4 Gate/Expander This section can act as a 20:1 Gate or as a 2:1 Expander when the EXP button is pressed. RANGE Determines the depth of gating or expansion. When turned fully anti-clockwise, this section is inactive. When turned fully clockwise, a gate depth or range of 40dB can be obtained. THRESH Determines the level at which the gate opens or the level below which gain reduction begins (EXP selected), adjustable from approximately -30dBu to +10dBu.
