Software Reference Manual
10. Gate Release. Sets the rate at which the gate for the selected channel closes. Gate-release times
should typically be set so that the natural decay of the instrument or vocal being gated is not affected.
Shorter release times help to clean up the noise in a signal but may cause “chattering“ with percussive
instruments. Longer release times usually eliminate chattering and should be set by listening carefully for
the most natural release of the signal. The release time can be set from 0.05 to 2 seconds.
11. Gate Key Filter. Sets the frequency at which the gate will open. Setting a specific frequency, in addition
to a specific decibel level, provides more sonic shaping. The Key Filter can be triggered by the selected
channel or bus’s signal or by side-chaining a channel and using its signal as the source.
Power User Tip: A properly set key filter on a gate can greatly improve the overall sound quality of a mix.
For example, if you are inserting a gate on a snare-drum mic, you may get enough bleed from the kick
drum to open the gate. This is where a key filter can come in handy. By setting the key filter to remove
some of those low frequencies, the gate won’t be as apt to open for the kick drum.
12. Gate Expander Button. StudioLive mixers allow you to choose between an expander and a noise gate for
each channel or output. By default, the Expander button will be enabled.
Power User Tip: In practice, expanders and noise gates are used almost identically. The main difference
is that an expander is smoother and more gradual, so that it is easier to set the attack and release
times correctly.
13. Key Listen. Enable to listen to the signal being used to trigger the gate.
7.1.1 Key Filter Sidechaining
As previously mentioned, the key filter can be sidechained to another channel. Sidechaining has many uses.
You can use a sidechained key filter to tighten up a rhythm section by sidechaining the kick drum channel to
the bass channel and setting the gate to open at the frequency of the kick drum. This, combined with a fast
attack and release, will make your rhythm section more cohesive. Increase the release time to loosen the feel.
Please note that while sidechaining the kick drum to the bass channel can tighten up a good rhythm section
and make them sound even better, it will not correct timing issues and will actually exaggerate them if your
bass player and drummer aren’t in the pocket.
Another great use for a sidechain is as an effect in electronic music production. Try sidechaining a drum loop
to a sustained source, like pads or strings. By doing this, every time a drum hit triggers the key filter, your
sustained source will be heard. Between hits, this source will be silenced. Playing with the attack and release
will transform this effect from a rhythmic pulse all the way to a chopped-up stutter.
7.2 Compressor
To view the controls for the Compressor, click on the Compressor tab.
1. Compressor On/Off. Turns the Compressor On and Off for the selected channel.
2. Output Meter (Series III only). Displays the post-Compressor output signal.
3. Gain Reduction Meter (Series III only). Displays the amount of gain reduction being applied to the signal
by the compressor.
4. Auto Mode Button. When Auto mode is active, the Attack and Release controls become inoperative,
and a preprogrammed attack and release curve is used. In this mode, the attack is set to 10 ms, and the
release is set to 150 ms. All other compressor parameters can still be adjusted manually.
5. Soft Knee Toggle Button. Engages Soft-Knee Compression. In normal operating mode, the compressor
is set for hard-knee compression, meaning that the gain reduction applied to the signal occurs as soon
as the signal exceeds the threshold. When the Soft Knee button is engaged, the onset of gain reduction
occurs gradually after the signal has exceeded the threshold.
