CHAPTER 20. LIVE AUDIO EFFECT REFERENCE 285
Adjusting the HiPass control will cut low frequencies from the delayed signal.
The Dry/Wet control adjusts the balance between the processed and dry signals. Set it to
100 percent if using Flanger in a return track.
20.13 Gate
The Gate Effect.
The Gate effect passes only signals whose level exceeds a user-specied threshold. A gate
can eliminate low-level noise that occurs between sounds (e.g., hiss or hum), or shape a
sound by turning up the threshold to where it cuts off reverb or delay tails or truncates an
instrument's natural decay.
The Threshold slider sets the gate's sensitivity. If the gate is open and passing signal (i.e.,
the signal exceeds the gate threshold), the green LED lights.
The Attenuation slider, located beneath the Threshold fader, can attenuate signals below
the threshold rather than just cutting them off. If set to -inf dB, a closed gate will mute the
input signal. A setting of 0.00 dB means that even if the gate is closed, there is no effect
on the signal. Settings in between these two extremes attenuate the input to a greater or
lesser degree when the gate is closed.
With the Flip button enabled, the gate works in reverse; the signal will only pass if its level
is below the threshold.
The Attack time determines how long it takes for the gate to switch from closed to open
when a signal goes from below to above the threshold. Very short attack times can produce
