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.
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.
INTELLIGATE XR2000 1.2.1 Front panel Fig. 1.2: Control elements of the Expander section 2 The 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. 3 The 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.
INTELLIGATE XR2000 Fig. 1.3: Control elements of the Key Filter section 12 The tunable Key Filter section is switched into the sidechain path when the FILTER switch is pressed. 13 The LOW CUT control adjusts the cut-off frequency at which the high pass filter rolls off low frequencies in the sidechain path. It has a slope of 12 dB/octave and has a control range from 30 Hz to 3 kHz.

This is the key signal output for the connection of external units. 23 KEY RETURN. This is the key signal input for the connection of external units. 2. OPERATION 2.
INTELLIGATE XR2000 2.2.1 THRESHOLD control The THRESHOLD control of the Expander defines the operating level. It stretches across a very wide range and therefore applies to all working levels. Input levels above the adjusted threshold point do not experience any change. However, if the level falls below the threshold, the dynamics process is active. Simple noise-gates only provide you with one control for adjusting the threshold. Controls for varying the envelope parameters are omitted.
INTELLIGATE XR2000 2.2.3 RANGE control The control of the dynamics process in the INTELLIGATE is provided by a high performance VCA. Its effective range is more than 100 dB, which means that the input signal can be attenuated up to 100 dB. In most applications, it is not desirable for the signal to be gated off completely when the signal drops below the threshold.
INTELLIGATE XR2000 A ratio of 1:1 indicates, that the output signal will correspond to the input signal i.e., there is no level change. A ratio of 2:1 indicates, that for every 1 dB decrease in input level below the threshold, there will be resultant corresponding decrease in the output level of 2 dB. A ratio of 30:1 indicates, that for a 1 dB decrease in input level below the threshold, there will be a corresponding decrease in the output level of 30 dB etc. 2.
INTELLIGATE XR2000 Please note when the KEY LISTEN switch is engaged, the audio processing facility of the respective channel is disabled. With the KEY LISTEN function activated, the key filter section can be used as an independent fully functional equalizer section. 3. APPLICATIONS In this section, several typical applications of the BEHRINGER INTELLIGATE are discussed. The following basic settings can resolve most dynamic problems. They are the ideal starting point.
INTELLIGATE XR2000 THRESHOLD control Now adjust the THRESHOLD control anticlockwise, until the softest hit on the percussion instrument triggers the Expander so that the desired signal will pass unaffected. Triggering of the Expander will be monitored by the flash of the ABOVE LED. If you have correctly adjusted the unit, you will hear the instrument clearly stand out from the programme material. ATTACK control Most instruments are characterized by their typical initial profile.
INTELLIGATE XR2000 Similarly, with a fine adjustment of controls mentioned, the dynamic range of an instrument can be artificially expanded. Expansion can achieve good results, expecially with sampled sounds, because samplers only have a heavily restricted dynamic range. When processing drum sounds (e.g. a snare), downward expansion can result in insteresting effects. If for instance the threshold is set to an intermediate level, then only the lower part of the dynamics will be processed.
INTELLIGATE XR2000 As well as this, an extremely quick attack time is necessary for very fast transients, so that the expander does not loose the initial transients and affect the sound. 3.4.2 Reducing leakage in stage mics The INTELLIGATE has many uses especially in live-work, on stage and in multi-miking situations: a well set up expander can effectively suppress background noise, compressor type pumping noise and microphone leakage etc. without producing any undesirable side effects.
INTELLIGATE XR2000 3.5 Using the INTELLIGATE to change the sound 3.5.1 Reshaping sample sounds With the help of the BEHRINGER INTELLIGATE, existing or new sampled sounds can be brightened up, changed or used to create new sounds. The attack times and the dynamics of the sound can be changed as desired. 3.5.2 Altering the texture of musical instruments In addition, the INTELLIGATE can be used to change sound characteristics.

Rotate the THRESHOLD control anticlockwise until the GAIN REDUCTION meter shows an appropriate drop in level. 2.
INTELLIGATE XR2000 Dynamic feedback control is a better solution. Similar to the de-esser application, the Key Filter section is inserted into the sidechain path by pressing the FILTER switch. To effectively suppress feedback, the centre frequency of the filters are correctly adjusted to match the room’s resonant frequency. This selected frequency now controls the BEHRINGER INTELLIGATE. As soon as feedback occurs, the unit temporarily reduces the system gain and thus effectively suppresses the feedback.
INTELLIGATE XR2000 5.3 “Voice Over” applications The BEHRINGER INTELLIGATE can also be used to automatically reduce music to a background level, when an announcer is speaking through a microphone. This application is found in broadcasting, as well as in PA systems, where background music is automatically attenuated when an announcement is made. This application is known as “voice-over” ducking.
INTELLIGATE XR2000 5.4 Anticipated expansion If you feed the audio signal directly into the KEY RETURN input and send the audio signal through a delay before the audio input, the BEHRINGER INTELLIGATE can anticipate the need for gain change. With experimentation, the effect can create a “zero” attack time at a given frequency.
INTELLIGATE XR2000 6. INSTALLATION 6.1 Mains voltage Before you connect the 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. The 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°.
