The reference-class XR4400 gives you 4 frequency-selective UTR (Ultra Transient Response) Expander/ Noise Gate channels in a single rack space – without compromising on functionality. The Side Chains’ parametric filters allow you to fine-tune control signals, so the Gate only reacts when you want it to. The highly versatile MULTIGATE PRO XR4400 is extremely effective for suppressing crosstalk in multitrack recording applications, and for reducing crosstalk and feedback when using multiple open stage microphones.

The innovative FlexLink function implemented in the XR4400 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 the neighboring channel 2 becomes the “master” – now controlling all parameters for both channels. To control channels 2 and 3 from channel 1, simply press the Couple switches of channel 2 and 3.

With the Mode switch in the “Off ” position (up), the XR4400 works in Gate mode, and applies an extremely-fast attack time to gate all kinds of drum and synthesizer sounds – without cutting off their percussive edge. In Expander mode (down), the XR4400 analyzes the shape and dynamic content of the input signal to calculate the control time parameters – thus working as an interactive Expander that adapts automatically to the program signal. The result: guitar sounds, vocals and complex mix signals can be “cleaned” without audible clicks, breathing or other unwanted sounds. Additionally, you can use this function to freely expand any type of program material’s dynamic range.
