MULTIGATE PRO XR4400
6This 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.
7The 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.
+The HOLD control is enabled in GATE mode only!
8The RELEASE control determines the time of the release process. This process begins after the end of
the hold phase and ends when the gain reduction adjusted with the RANGE control is achieved. The
setting range of the RELEASE control is from 0.05 to 4 seconds.
+The RELEASE control is enabled in GATE mode only!
9The MODE switch is used to set the operating mode of the respective channel. When the switch is out,
the corresponding section works as an ultra-fast gate. In this mode, even percussive signals can be
processed without any signal loss. With the MODE function on, the IRC expander (Interactive Ratio
Control) is activated. This interactive control function allows for the program-dependent expansion of
complex signals. Both the attack time and the fade-out characteristics (ratio) vary depending on the
program material. The agreeable results of this automatic process are less critical adjustment work and
inaudible expansion of the program material.
10 The RANGE/RATIO control performs a dual function: depending on the position of the MODE
switch (i.e. depending on the operating mode of the unit: gate or expander), the RANGE/RATIO control
determines the maximum amount of gain reduction or the expansion curve. In gate mode, this control
adjusts the RANGE determining the amount of maximum gain reduction from 0 dB to -80 dB. In
expander mode, it works as a RATIO control setting the expansion ratio. The ratio function determines
the input vs. output level ratio, for all signals below the threshold. The setting range is from 1:1 to 1:4.
11 The 8-digit GAIN REDUCTION meter informs you about the current amount of gain reduction within a
range from 1 to 40 dB.
12 When you press the COUPLE switch, this channel is automatically configured as a slave channel. Its
left neighbor becomes the master now controlling both channels in all their parameters.

13 FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local voltage matches the volt-
age indicated on the unit, before you attempt to connect and operate the MULTIGATE PRO. Blown
fuses may only be replaced by fuses of the same type and rating.
14 MAINS CONNECTION. Use the enclosed power cord to connect the unit to the mains. Please also note
the instructions given in the INSTALLATION chapter.
15 AUDIO IN. These are the audio inputs of your MULTIGATE PRO, available both as balanced 6.3 mm
jack and XLR connectors.
16 AUDIO OUT. These are the audio outputs of your MULTIGATE PRO. Matching phone jack and XLR
connectors are wired in parallel.
