product description:
This product has a fully automatic howling point detection function, uses DSP high-speed floating point computing technology, and adopts adaptive feedback control algorithm, notch algorithm, bass compensation algorithm, automatic mixing algorithm, etc. to perform high-speed feedback processing of the sound. The maximum It restores the fidelity of the sound to a certain extent, realizes fully automatic feedback elimination and sound field correction, real-time response, one-button operation and fully automated operation, and effectively improves the pickup distance of the microphone.
Features:
Adopt adaptive professional algorithm and intelligent high-speed feedback processing, which can greatly suppress howling and effectively prevent burning of audio equipment and speakers.
One-button control feedback suppression switch function and one-button pink noise test and calibration function, on-site debugging is extremely simple and convenient
One-click intelligent and manual-free debugging. Regardless of changes in location, temperature, humidity, or decoration in the room environment, system installation does not require sound field debugging.
Compatible with hand-in-hand conference microphones and analog conference microphones, effectively increasing the microphone gain by 6-12dB, and the speaking distance is 30-80CM
The front panel color screen displays the device status in real time: input signal power, output level, system voltage, device stability, etc.
Six MIC balanced (unbalanced) signal inputs and two balanced signal outputs, each balanced input with independent gain adjustment and 48V phantom power supply
The sixth microphone supports separate feedback and bypass working modes to facilitate system signal management.
Supports independent gain adjustment function for each input and 48V phantom power supply that can be switched independently
Two sets of Lotus (RCA) auxiliary inputs and two sets of Lotus (RCA) auxiliary outputs, compatible with connecting more devices
Six MIC signal inputs and line lotus (RCA) signal input with adjustable high and low frequencies
