Digital Feedback Suppressor

— Designed with a standard 19-inch rackmount 1U format, it is compact and lightweight. The front panel features an  integrated aluminum alloy faceplate, while the chassis is made of high-strength sheet metal stamping. 

— Equipped with an 8-core DSP design, it incorporates dual-channel 24-band high-precision digital notch filters to  accurately locate and eliminate howling frequencies. Additionally, it features automatic phase and frequency shifting  functions, providing superior howling suppression capabilities.  

— Come with a bypass/operating mode switch for easy activation of the anti-howling processing mode, making system  debugging simple and straightforward.  

— The control panel features a 2-inch true-color LCD display that supports displaying information such as input signal  strength, number of channel notch filters, volume levels, and operating modes.  

— Offer 2 balanced/unbalanced inputs and 2 balanced/unbalanced outputs.  

— Utilize AF-AM attenuation factor audio data mixing technology, enabling intelligent mixing of input signals and supporting  adjustment of input signal gain levels for easy matching with various devices.  

— Features a USB port that supports firmware upgrades and advanced settings via computer software. 

— The front control panel includes buttons for mode switching, operation, system settings, and a jog dial, supporting  volume and menu setting functions.  

— Equipped with dual 24-band parametric equalizers and high/low-pass filters, it supports acoustical defect correction in  different environments.  

— Support the setting of static filter quantities, with a maximum of 16 filters.  

— Incorporate a microphone amplifier circuit with 48V phantom power, supporting both dynamic and condenser  microphones.  

— The output signal offers selectable high/low levels, enabling direct connection to a wider range of downstream devices  such as amplifiers and mixing consoles.  

— Feature 10 scene preservation and recall functions, allowing the storage and retrieval of parameters for 12-band  equalizers and howling rejection filters for 10 scenes. These settings are automatically recalled upon the next power-on. 

— Compatible with visual management software, it supports AB channel switching, equalizer, level, crossover/compressor,  notch filter, noise gate, and input signal gain settings. It also includes configuration file import/export functionality and  supports Chinese/English language switching.  

— Feature an efficient airflow design that provides excellent heat dissipation performance, effectively ensuring stable  operation over extended periods.  

— Suitable for use with hand-in-hand conference systems, wired and wireless conference microphones.
