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.

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.

+The HOLD control is enabled in GATE mode only!

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.

The RELEASE control is enabled in GATE mode only!

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.

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.

The 8-digit GAIN REDUCTION meter informs you about the current amount of gain reduction within a range from 1 to 40 dB.

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 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.

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.

AUDIO OUT. These are the audio outputs of your MULTIGATE PRO. Matching phone jack and XLR connectors are wired in parallel.
