<h2>Inputs and Outputs</h2>
|
||
|
|
<p>The single channel gate has one audio input and one
|
||
|
|
audio output.</p>
|
||
|
|
<p>The stereo gate is identical to the single channel version
|
||
|
|
except that it has 2 inputs and 2 outputs. Adjustment
|
||
|
|
of controls has the same effect on both channels.</p>
|
||
|
|
<p>If the side chain option is switched on an additional
|
||
|
|
input is available, giving access to the control side
|
||
|
|
chain.</p>

<h4>Side chain</h4>
|
||
|
|
<p>A side chain input can be made available so that an
|
||
|
|
equaliser, for example, can be introduced to make gating
|
||
|
|
frequency conscious. Any side chain processing would normally
|
||
|
|
derive its signal from the same source that is fed to
|
||
|
|
the audio input of the gate.</p>
