INTELLIGATE XR2000
1. INTRODUCTION
In purchasing the INTELLIGATE, you have acquired an extremely efficient and universal dynamics processor. The unit is a versatile, high quality expander, gate and ducker for recording and broadcast situations, post production suits etc. It can therefore be used for recording or eliminating noise in audio recordings, automatically shutting down open mics in PA systems, increasing dynamics in heavily compressed music, improving the dynamic range of noisy communication systems, creating special effects for varying sound styles etc.
Advanced BEHRINGER Technology
Despite the extremely complex internal circuitry, the unit has a control surface which is clearly laid out and easy to understand. The internal design of the unit, together with its external sidechain path, gives the user unsurpassed creative flexibility when processing sound.
The BEHRINGER INTELLIGATE contains several new circuit designs which make the unit the ultimate expander/ gate/ducker.
UTR (Ultra Transient Response) Gate
With an attack time of 3 s, the BEHRINGER INTELLIGATE is one of the fastest gates known, that have been designed. An extremely quick attack time is necessary for very fast transients, e.g. for hand claps or percussive instruments, so that the gate does not loose the initial transients and affect the sound.
The new UTR (Ultra Transient Response) circuit, in conjunction with a Class-A VCA circuit, the unit allows for instantaneous attack parameters without the all too familiar, nightmarish switching noise, found when using conventional gates.
IRC (Interactive Ratio Control) Expander
A basic problem in the use of a noise-gate is that generally these devices provide you with little more than a simple “on/off” switch. When attempting to fade noise out of complex programme material, the unit would inadvertently create undesirable side effects.
To eliminate this problem, one would use an additional expander, which would create a continuous and gently fade. However, simple expanders, even when they are used correctly, drastically cut signals below the preset threshold. This effect becomes more noticeable during the transition from signal to noise floor. This can mean that the start or end of words can be cut on a vocal track.
A newly developed IRC (Interactive Ratio Control) expander has been integrated into the INTELLIGATE. The ratio of which, is automatically adjusted, dependent on programme material. The result is an expander which is less critical of adjustment and which is more tolerant in the presence of those signals which appear slightly above the noise floor.
In conjunction with the gate function, the IRC expander is an excellent tool for all associated sound engineering situations. Additionally, the extensive control parameters allow for a focussed and successful solution whilst processing all types of programme material. Without compromise, the unit meets the highest demands with regard to operation, sound, specifications and manufacture.
This manual first describes the terminology used, so that you can fully understand the INTELLIGATE and its functions. Please read the manual carefully and keep it for future reference.
1.1 Before you begin
Your INTELLIGATE was carefully packed in the factory and the packaging is designed to protect the unit from rough handling. Nevertheless, we recommend that you carefully examine the packaging and its contents for any signs of physical damage, which may have occurred during transit.
If the unit is damaged, please do not return it to BEHRINGER, but notify your dealer and the shipping company immediately, otherwise claims for damage or replacement may not be granted. Shipping claims must be made by the consignee.

1. INTRODUCTION |
INTELLIGATE XR2000
The BEHRINGER INTELLIGATE fits into one standard 19" rack unit of space (1 3/4"). Please allow at least an additional 4" depth for the connectors on the back panel. Be sure that there is enough air space around the unit for cooling and please do not place the INTELLIGATE on high temperature devices such as power amplifiers etc. to avoid overheating.
Before you connect your INTELLIGATE to the mains, please make sure that your local voltage matches the voltage required by the unit:
The fuse holder on the female mains connector has 3 triangular markers, with two of these triangles opposing each other. Your INTELLIGATE is set to the operating voltage printed next to these markers, and can be set to another voltage by turning the fuse holder by 180°. CAUTION: this instruction does not apply to export models exclusively designed, e.g. for 115 V operation!
The mains connection of the INTELLIGATE is made by using the enclosed mains cable and a standard IEC receptacle. It meets all of the international safety certification requirements.
Please make sure that all units have a proper ground connection. For your own safety, never remove or disable the ground connector of the unit or of the AC power cable.
As standard, the BEHRINGER INTELLIGATE is installed with electronically servo-balanced inputs and outputs. The new circuit design features automatic hum and noise reduction for balanced signals and thus allows for trouble-free operation, even at high operating levels. Externally induced mains hum etc., will be effectively suppressed. The automatic servo-function recognizes the presence of unbalanced connectors and adjusts the nominal level internally to avoid level differences between the input and output (correction 6 dB).
You will find additional information in chapter 6 “INSTALLATION”.
1.2Control elements
Fig. 1.1: The control surface of the INTELLIGATE
The BEHRINGER INTELLIGATE has two indentical channels. Each channel is equipped with 5 push button switches, 8 rotery controls and 11 LEDs. The COUPLE switch is for stereo operation:
1The INTELLIGATE converts to stereo mode by engaging the COUPLE switch, where the left channel assumes the control of both audio paths, whereby the control voltage of channel 2 will be replaced with that of channel 1. By depressing the COUPLE switch, you overide all the controls and switches of channel 2 with the exception of the IN/OUT and the KEY LISTEN switch. Channel 1’s controls completely take over the functions of channel 2.

1.2.1 Front panel
Fig. 1.2: Control elements of the Expander section
2The IN/OUT switch engages the corresponding channel. This switch is used to make direct A/B comparisons between source material and the processor’s effected signal.
3The THRESHOLD control adjusts the threshold level for the expander/gate section in the range of -50 to +20 dBu. Signals below this level cause attenuation. As the key signal passes through threshold, the release and hold functions are triggered, dropping the gain of the Expander/Gate to the value determined by the RANGE control 
. In Ducker mode these funtions are reversed.
4The ATTACK control adjusts the time taken to reach unity gain after the key signal exceeds threshold. When in the Ducker mode, this control adjusts the rate of attenuation after the key signal exceeds the threshold. The control range lies between 3 s and 90 milliseconds.
5The HOLD control adjusts the period of delay before the onset of the release function, after the signal falls below the threshold. The control range lies between 8 milliseconds and 4 seconds.
6The RELEASE control adjusts the time taken for the gain to be reduced to a value set by the RANGE control. When in the Ducker mode, this control adjusts the rate of recovery to unity gain after the hold cycle is complete. The control range lies between 10 milliseconds and 2 seconds.
7Use the RATIO control to adjust the ratio of the downward expander. It defines the relationship between the input and the output level which fall below the threshold. The control range lies between1.2:1 to 30:1.
8The RANGE control determines the maximum amount of attenuation. The control range lies between 0 dB up to 100 dB.
9The DUCKER switch changes the operation from the Expander to the Ducker and the control signal is inverted. When the key signal exceeds the threshold, the gain of the Ducker is now decreased and the output is returned to unity gain when the key signal falls below the threshold.
10The arrangement of the LEDs in this application is called “traffic lights” and indicates the operating status of the unit. The BELOW LED (red) indicates that the key signal is below threshold. The HOLD LED (yellow) indicates that the hold circuit is active. The ABOVE LED (green) indicates that the key signal is above threshold.
11The 8-stage GAIN REDUCTION meter informs you of the actual gain reduction and displays this in a range of 0 to 40 dB.
