[. . . ] XR4400 Users Manual Version 1. 1 April 2001 E ENGLISH MULTIGATE PRO ® www. behringer. com MULTIGATE PRO XR4400 SAFETY INSTRUCTIONS CAUTION: To reduce the risk of electric shock, do not remove the cover (or back). No user serviceable parts inside; refer servicing to qualified personnel. WARNING: To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture. This symbol, wherever it appears, alerts you to the presence of uninsulated dangerous voltage inside the enclosurevoltage that may be sufficient to constitute a risk of shock. This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. [. . . ] CONTROLS MULTIGATE PRO XR4400 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. The HOLD control determines the delay applied to the starting point of the release process, after the signal has dropped below the threshold. 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 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. [. . . ] This also applies to defects caused by normal wear and tear, in particular, of faders, potentiometers, keys/buttons and similar parts. Damages/defects caused by the following conditions are not covered by this warranty: s misuse, neglect or failure to operate the unit in compliance with the instructions given in BEHRINGER user or service manuals. s connection or operation of the unit in any way that does not comply with the technical or safety regulations applicable in the country where the product is used. s damages/defects caused by force majeure or any other condition that is beyond the control of BEHRINGER.
