Never use unbalanced XLR connections with microphone cables, as this
would short-circuit any phantom power transmitted over these cables!
4. Controls
The BEHRINGER MULTIGATE PRO has four channels. Each of these channels is
equipped with 3 or 4 push-buttons, 6 rotary controls and 11 LEDs.

(1)
The
FREQUENCY
control determines the lower limit frequency of the
sidechain filter, and covers a range from 100 Hz to 10 kHz.
(2)
The
BANDWIDTH
control determines the slope or bandwidth of the
sidechain filter. The bandwidth can be set within a range from 2.3 to
0.7 octaves, so as to realize even extremely narrow-band filter settings.
(3)
The
FILTER
control activates the parametric sidechain filter. To edit this filter
there you can use the frequency and BW control.
(4)
The
MONITOR
switch establishes a link between the sidechain control signal
and the audio output. As it also mutes the audio input signal the user can
pre-monitor the parametric filter output, which makes it easier to tune the
filter by ear.
◊
Please note that the MONITOR switch disables the channel’s audio signal.
(5)
Use the
THRESHOLD
control to set the threshold point of the expander/
gate function within a range from BYPASS to +10 dBu. Signals below the
threshold are reduced in level. When the signal drops below the threshold,
the hold/release function starts reducing the signal to a level adjustable
with the RANGE/RATIO control.
◊
Please note that the MULTIGATE PRO enters bypass mode, when the
THRESHOLD control is set to its left stop position, i.e. all processing
functions are disabled and the signal is routed directly from the input
to the output.
(6)
This “traffic light” LED chain shows the current operating mode of the unit:
the “+” LED (red) indicates that the sidechain signal is below the threshold,
the
HOLD
LED (yellow) informs you that the hold circuit/release process has
been activated, while the “-” LED (green) shows that the sidechain signal is
above the threshold.
(7)
The
HOLD
control determines the delay applied to the starting point of
the release process, after the signal has dropped below the threshold.
The setting range is 0 to 4 seconds.
