NP3A AI Speech Enhancement Processor
AI width learning algorithm, ANS, AFS, AGC；
Reduce the non-human noise in the process of speech sound reinforcement, and improve the speech intelligibility；
Suitable for conferences, education, live broadcast, interviews, multi-function halls etc.
Characteries:
l Adopt ADI 4th generation DSP chip-ADSP-21489 400MHz, 32/40-bit floating-point DSP, 48KHz sampling rate;
l Adopt professional-grade 24-bit A/D and D/A conversion chips,
l Adopt ELNA electrolytic capacitors and other world-famous audio-specific devices, and the sound is pleasant;
l Two-line input (Input can be set to Line or Microphone, +48V phantom power) Output, Link synchronization adjustment, LINK one-key setting;
l ANS artificial intelligence noise suppression algorithm, total of 11 levels settings;
l AFC frequency shift feedback suppression algorithm, which can be set to on or off;
l AGC can improve the problem of loud and small sounds caused by distance changes and other reasons when speaking, and it is better to use with ANS;
l HPF / LPF high and low Pass switch, one-key switch as needed;
l One-key operation, cooperating with the Encoder, it is convenient and quick to set the parameters. The panel is automatically locked to prevent mis-operation;
l 2*20 LCD to display signal and status;
l Full-port RF protection to protect the safe and reliable operation of the equipment;
l Flexible application and flexible access to other devices as required.
