The 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.

(9) 

The 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.

FUSE HOLDER / VOLTAGE SELECTOR. Please make sure that your local 

voltage matches the voltage 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.

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.

As already described, a so-called downward expander automatically reduces 

the overall level of all signals that drop below an adjustable threshold, and thus 

expands the dynamic range of the program material. In other words, an expander 

is the opposite of a compressor. Expanders usually work with a relatively flat ratio 

curve to fade out the signal smoothly.
Noise gates are a special form of expander using a much steeper ratio curve to 

abruptly cut the signal when it drops below the threshold. As expanders and 

gates are quite similar in what they do the following description of expanders 

and their functionalities also applies to noise gates.

Like the COMPOSER, INTELLIGATE, MULTICOM, and others, the MULTIGATE PRO 

uses the newly developed INTERACTIVE principle based on a chain of intelligent 

control functions. For example, the IRC expander (Interactive Ratio Control) 

does not use a fixed ratio curve but varies this curve depending on the input level 

and the setting of the THRESHOLD control.
