Introduction
The AFS6 feedback suppression system has the function of fully automatic detection of ready-made howling points, and the sound is filtered through the DSP system, which can effectively suppress the noise at a high speed, and effectively improve the sound pressure and clarity of the local sound reinforcement.
The system design is flexible and changeable. It has 4 universal input interfaces, 2 balanced output interfaces, and is equipped with line input and output lotus interfaces, which is simple and convenient to debug.
Each channel has a 48V phantom power supply. This product is mainly researched and developed for modern teaching, conference, court hearing recording and remote conference calls.
It’s suitable for meeting rooms, theaters, auditoriums, classrooms, multi-purpose halls and other places with high-level sound requirements
►4 Channels input interfaces, independent 48V power supply for each channel
►There are high, medium and low levels adjustable.
►The panel is equipped with a level display, which can display the current working status and signal level
►Panel one-key professional digital feedback suppression module, direct/feedback mode can be switched, no need to adjust, increase the microphone pickup distance by more than 30-100CM
► One-key quick calibration of the panel, which restores the fidelity of the sound to a large extent, thereby effectively suppressing more reflection components
►Standard 1U chassis, high-grade brushed aluminum alloy panel.
►1 line input lotus interface
►1 line output lotus interface
►The panel has system signal volume adjustment
►The panel has line input signal volume adjustment
►1.77-inch TFT color screen display, monitor output level at a glance
