Gate
While the dynamic section is addressing the gate, all of its controls are enabled except the Make Up control and KNEE buttons.
1. Threshold - Sets signal level at which gate opens. Range is from -50 dB to +25 dB.
2. Range - Control adjusts the amount of gain reduction applied to the signal below threshold. Controls the maximum gain reduction that is possible. Range is from
minus innity (-∞) to zero.
3. Attack - Adjusts time taken for gate to open after an over-threshold signal. Range is from 0.02 ms to 20 ms
4. Release - Adjusts time taken for gate to close after programme material falls back below threshold. Range is from 2 ms to 2.000 s.
5. Hold - Minimises chattering in conjunction with internal hysteresis. Once the signal drops below the threshold, this denes a waiting period before the gate
starts to close. Range is from -0.005s to 2.000s
6. On - Enables the gate in the signal path. When switched o, gate is bypassed.
7. Input level - Shows input into the gate.
8. Gain Reduction - Shows attenuation of signal in dB.
9. Sidechain Display - Shows the Sidechain frequency graphically.
10. Filter On/O - Enables the Sidechain lter into the signal path. Use arrow to expand Sidechain view.
11. Mode - Switch between Gate or Ducker
Ducker
In radio this can typically be achieved by lowering (ducking) the volume of a secondary audio track when the primary track starts and lifting the volume again when
the primary track is nished. A typical use of this eect in a daily radio production routine is for creating a voice-over.
Use of the sidechain allows the ducker on the channel you wish to be turned down to be triggered by the channel you wish to have priority.
Sidechain
The sidechain lter is a swept band pass type, which acts on the compressor and gate/ducker which covers the full audio spectrum. There are four lter Q widths
available, 0.1 Oct (tightest), 0.3 Oct , 1 Oct and 2 Oct (widest). This allows you to narrow the frequency response of the sidechain for more detailed control. The
sidechain graph shows the eects of the sidechain lter on the signal, selectable via the Width button.
Sidechain Listen button, allows the audio signal to be monitored via the solo bus for ne tuning the frequency selection.
Tip: For snare drum gating try setting the width at 0.3 Oct and the frequency around 2k. This can help cut out spill from other close drums and give a cleaner drum
sound. Snare bottom mics could also be triggered or keyed from the snare top mic to allow the gate to open faster and allow super quick transients through.
