point of time. Also when synchronizing several instruments, inaccurate entries of individual musicians can be avoided.

To expand phase-coherent stereo signals (i.e. signals having the same phase), it is imperative that the control processes be triggered simultaneously in both channels. Due to the differences in perceived loudness between the left and right channels, unwanted shifts with reference to the stereo basis would be produced.

The innovative FlexLink function implemented in the MULTIGATE PRO allows for a variety of couple options. For example, when you press the COUPLE switch of channel 3, this channel is automatically configured as a “slave” channel, while its neighbor—channel 2—becomes the “master” now controlling both channels in all their parameters.

Activating the COUPLE switch automatically disables all controls and switches of channel 3 (except for the MONITOR switch). Now, the controls of channel 2 take over full control of channel 3. Similar to a stereo fader, both channels work in sync. To control channels 2 and 3 from channel 1, simply press the COUPLE switches of channel 2 and 3.

5.4 The SIDECHAIN filter

Each channel has a parametric filter whose frequency and quality (bandwidth) can be set precisely. This tunable filter allows you to select and fade out specific frequencies that would otherwise lead to unwanted triggering of the expander circuit.

5.4.1 The MONITOR function

This switch links the sidechain control signal with the audio output, while muting the audio input signal, so that you can pre-monitor the filter output and tune the parametric filter.

+Please note that the channel’s entire processing functions will be disabled when you press the MONITOR switch.

6. APPLICATIONS

This chapter describes a few typical applications of the BEHRINGER MULTIGATE PRO. Starting from the basic setting shown below you can find solutions to most dynamics-based problems. Please take your time to study the following application examples thoroughly, so as to be able to fully exploit the variety of features your MULTIGATE PRO offers.

Basically, the BEHRINGER MULTIGATE PRO can be used in three areas of application:

1.Eliminating interference noise and suppressing crosstalk in multi-channel or multi-microphone configura- tions.

2.Expanding the dynamic range of compressed program material, refreshing sampled sounds and creating special effects and sounds.

3.Using the MULTIGATE PRO as a de-esser and to specifically eliminate interference noise from recordings as well as to reduce the risk of feedback in live situations.

6.1 Basic setting

Understandably, there is no standard setting that suits all kinds of applications. Rather, the controls and switches must be set specifically for the application on hand. However, by studying the following practice- oriented descriptions of typical applications you will soon develop a feel for how the various functions work:

6.1.1 The gate function

“Gating” is a so-called “high ratio” expander function and represents the simplest function of the BEHRINGER MULTIGATE PRO. When the expander is operated with maximum gain reduction (RANGE control fully to the left), it works in “hard gating” mode. The gate function is used to automatically mute single channels in
