Audio processor
Audio processor
- Visual feedback howling display function, effectively suppressing the formation of more howling points.
- Built-in central control code generator, no need to manually apply formulas to edit code.
- Full-featured matrix mixing function, with a unique component-based matrix adjustment function.
- Built-in signal generator, automatic mixing (AM), automatic gain control (AGC), feedback suppression (AFC), echo cancellation (AEC), and noise cancellation (ANC) as main algorithms.
- Per input channel: preamplification, signal generator, expander, compressor, 5-band parametric equalization.
- Per output channel: 31-band graphic equalizer with switchable 8-band full parametric equalization, delay unit, crossover, limiter.
- Built-in automatic camera tracking function for easy video conferencing; supports scene preset functions; automatic protection memory in case of power failure.
- RS-485 bidirectional serial control interface; capable of controlling other external devices such as video matrices, cameras, and other RS-485 devices, or receiving third-party RS-485 control.
- Can connect to control devices via USB, WiFi, TCP/IP interfaces, and each input provides +48 VDC 10 mA phantom power.
- Supports 8-channel logic input/output, 4-channel voltage input control (compatible with relays or analog variable potentiometers) through GPIO control interface.
