3 Fat Channel Controls
3.1 Noise Gate
UC Surface
Reference Manual
7. Gate Threshold. Sets the level at which the gate opens. Essentially, all
signals above the threshold setting are passed through unaected, whereas
signals below the threshold setting are reduced in level by the amount
set by the range control. You can set the threshold from 0 to -84 dB.
8. Gate Attack. Sets the rate at which the gate opens on the selected
channel or output. A fast attack rate is crucial for percussive instruments.
Slow-rising signals such as vocals and bass guitar require a slower
attack; with these signals, a faster attack can cause an audible click. All
gates have the ability to click when opening but a properly set gate
will never click. You can set the attack time from 0.02 to 500 ms.
9. Gate Range. Sets the amount of gain reduction that the gate
will produce. The range can be set from 0 to -84 dB.
Note: Range control is not available when using the Expander.
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 aected. 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
specic frequency, in addition to a specic 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 lter 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
lter can come in handy. By setting the key lter 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 dierence 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.
3.1.1 Key Filter Sidechaining
As previously mentioned, the key lter can be sidechained to another channel.
Sidechaining has many uses. You can use a sidechained key lter 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 eect 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 lter, your sustained source will be heard.
Between hits, this source will be silenced. Playing with the attack and release will
transform this eect from a rhythmic pulse all the way to a chopped-up stutter.
