MULTIGATE PRO XR4400

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.


Fast and Versatile

The XR4400 utilizes IRC (Interactive Radio Control) Expander/Gate circuitry for virtually inaudible noise suppression, and features an extremely short attack time (<10 μsec) to capture ultra-high speed signals, such as drums and other percussive sounds. Adding to this, the XR4400 offers a parametric Side Chain filter (with monitor function) and separate, independent Hold and Release controls for the utmost in envelope-shaping flexibility. And we included our FlexLink system for awesome flexibility when used in master/slave configurations.



Interactive Attack Control

One of the XR4400’s most outstanding features is the program-dependent control of attack times. The IAC circuit (Interactive Attack Control) analyzes the program material to calculate the attack time by way of interaction, so the hold/release process is triggered automatically depending on the program material – which is why the XR4400 does not need a dedicated attack control!


Switchable Gate/Expander

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.
