A 45-degree line means that the input signal level equals the output signal level, in other
words, the Gate is having no effect. The output meter displays the level of the output
signal.

SIDECHAIN —When SIDECHAIN is off, the Gate is triggered by the input signal. On
the Stereo Gate, the trigger signal is derived by mixing the signals from both inputs, so
the higher of the two input signals will activate the Gate. When SIDECHAIN is on, the
Gate is triggered by the signal connected to the sidechain input.
THRESHOLD —This determines the level of the trigger signal required to open and
close the Gate. Trigger signals above the threshold cause the Gate to open, allowing the
input signal to pass unaffected. Trigger signals below the threshold, however, cause the
Gate to close, preventing the passage of the input signal.
RANGE —This determines the level to which
the Gate closes. Think of it as a brick holding
a garden gate open so that a certain amount
of signal always flows through. For a setting
of –70 dB, the Gate closes completely when
the trigger signal falls below the threshold.
For a setting of –30 dB, however, the Gate
half closes. For a setting of 0 dB, the Gate has
no effect. When signals are gated abruptly,
the sudden disappearance can sometimes
sound odd. This parameter causes the Gate
to reduce the signal level rather than cut it
completely.
ATTACK —This determines how fast the Gate opens when the trigger exceeds the
threshold level. Slow attack times can be used to remove the initial transient edge of
percussive sounds. Too slow an attack time makes certain sounds appear backwards.
HOLD —This determines how long the Gate stays open once the trigger signal has
fallen below the threshold level.
DECAY —This determines how fast the Gate closes once the hold time has expired. A
longer decay time produces a more natural gating effect, allowing the natural decay of
an instrument to pass through.
