2MULTIGATE PRO XR4400 Technical Specifications

MULTIGATE PRO XR4400

Reference-Class 4-Channel Expander/Gate

4 high-quality expander/gate channels

IRC (Interactive Ratio Control) expander/gate circuitry for virtually inaudible noise suppression

Extremely short attack time (<10 µsec) to capture ultra-high speed signals such as drums

Parametric side chain filter with monitor function

Independent Hold and Release controls for flexible envelope shaping

Maximum attenuation 80 dB

FlexLink system for ultimate master/slave configurations

Dedicated “Traffic light” Threshold and Gain Reduction LED indicators

Servo-balanced inputs and outputs with ¼" TRS and gold-plated XLR connectors

High-quality components and exceptionally rugged construction ensure long life

Conceived and designed by BEHRINGER Germany
