QUANTUM

4.3 Multiband Gate (cont.)

Ratio 1:1.0 to 1:15 (per band or global)

This is where you decide how much downward expansion you want. This ratio works back- wards from that of the compressor or limiter. If a ratio of 1:4 is selected, a signal that is 1dB below the threshold will be reduced in level so that it becomes 4dB below the threshold.

Attack 0.1 to 200 m Sec (per band or global)

As the signal reaches the threshold area, the Attack control sets the speed at which the gate opens. Use very fast attack times to catch the fronts of transient signals.

Hold 0 to 500 m Sec (per band or global)

The Hold control sets the amount of time the gate is held open after the signal passes below the threshold point.

Release 360 to 5 dB / Sec (per band or global)

Release sets the speed at which the gate “closes” when the end of the Hold time is reached.

Max ATT 0 to Inf. dB (per band or global)

This sets the maximum amount of attenuation for the gate.

4.4 Broadband Gate

The QUANTUM's broadband gate is available in the non-multiband chain types. It works just like the multiband gate with the exception of the fact that it functions on the entire signal band.

Within the Expander/Gate menu on the QUANTUM when in non multiband chains the follow- ing parameters are user adjustable.

Gate On/Off

Local (per band control) or global on and off.

Band 1 to 4 On/Off

Turns on or off each independent band

Threshold -75 to 0 dB

The threshold is the volume level at which the gate opens. Anything above the threshold pass- es, while signal that is lower than the threshold is attenuated. Beware, setting the threshold to high can cut off the tail end of signals as they fade out (the sustain of a guitar note, a held piano chord, a reverb tail, etc.).

Ratio 1:1.0 to 1:15

This is where you decide how much downward expansion you want. This ratio works back- wards from that of the compressor or limiter. If a ratio of 1:4 is selected, a signal that is 1dB below the threshold will be reduced in gain so that it becomes 4dB below the threshold.

Attack 0.1 to 200 m Sec

As the signal reaches the threshold area, the Attack control sets the speed at which the gate opens. Use very fast attack times to catch the fronts of transient signals.
