Gate/Expander Module - Mackie Spike User Manual

Gate/Expander Module

A gate is used to lower the level of a channel when the signal level drops below a certain threshold
level. This can reduce the overall noise level in your mix by muting unused or noisy channels.
The XD-2 Gate has controls to adjust attack, release, hold, threshold, and range. It can also be
turned into an Expander to allow ratio-based gain
reduction.
Note: When the gate opens, it means the
gate is not acting on the signal and the
signal is allowed to pass. When the gate
closes, the gate acts on the signal by at-
tenuating the signal level by the desired
amount.
Nodes T and R
Threshold and Range (or Ratio if EXPAND is on) can
be adjusted by grabbing the nodes with your mouse.
Ctrl (Control)-click to reset the nodes to their default
positions.
Reduction meter
This meter indicates the amount of gain reduction in
dB that is applied to the signal once it drops below
the threshold.
Input and Output meters
These meters indicate the signal level as it enters and exits the Gate/Expander module.
