We develop long lasting relationships that are built on trust. That is how we stay #1 in business providing consumer electronics to the United States and Canada.
The Behringer XR4400 Multigate Pro features 4 independent UTR (ultra transient response) expander/gate channels each with volume threshold and parametric frequency filters. This means the bass mic will not trigger the snare mic because the snare mic can be set not to respond to those bass frequencies. Behringer's superfast interactive circuitry completely eliminates clipped starts or chattering. 'couple' mode lets you operate channels independently or linked for stereo operation. Attack, hold and ratio controls are featured on each channel and led metering shows gate status and gain reduction. Servo-balanced 1/4" TRS and XLR connectors, 5-year warranty.
