Component Glossary

Adjustable Gc (AdjustGc)

One type of filter characteristic. With this setting, you can adjust Gc (gain on the cutoff frequency)
between -6 dB and +6 dB. If you set -3 dB it becomes a Butterworth filter. If you set -6 dB, it becomes
Linkwitz-Riley filter.
Components: Crossover, Crossover Processor, Crossover Processor II, Programmable BPF,
Programmable HPF, Programmable LPF, Speaker Processor

Attack (Attack Time)

In dynamic components, sets the time period for compressing or expanding the signal after the
component operates. As the attack time is made faster, compression or expansion becomes more
instantaneous. As it is made slower, the initial attack part of the sound will not be compressed or
expanded.
Components: Crossover Processor, Compander, Crossover Processor II, Compressor, De-
Esser, Ducking, Expander, Gate, Limiter, Speaker Processor
Bessel
One type of filter characteristic. For curves where phase characteristics are important, Bessel has
gentler attenuation then Butterworth, and there is little distortion of the waveform when square waves
are passed through.
Components: Crossover, Crossover Processor, Crossover Processor II, Programmable BPF,
Programmable HPF, Programmable LPF, Speaker Processor

Butterworth (Butrwrth)

One type of filter characteristics. This filter has the most general characteristics. The pass band is flat
and the gain for the cutoff frequency is -3 dB.
Components: Crossover, Crossover Processor, Crossover Processor II, Programmable BPF,
Programmable HPF, Programmable LPF, Speaker Processor
Bypass
Passes the signal without changing it. When you turn this ON, bypassed sound (unchanged sound) is
output. When you turn this OFF, the sound is output with effects applied.
Components: Crossover Processor, Crossover Processor II, GEQ, PEQ, BPF, HPF, LPF, Notch,
Programmable BPF, Programmable HPF, Programmable LPF, Speaker Processor, SPX

Decay (Decay Time)

Sets the time period until gain returns to normal after a trigger signal level falls below the threshold
value.
Components: Ducking, Gate, Auto Mixer
Delay
Sets the time period by which a signal is delayed.
Components: Crossover Processor, Crossover Processor II, Delay Long, Delay Short, Delay
Matrix, Speaker Processor, SPX, Slot Output, Unit Output
