Technical Features |
|
|
| |
·AV400 System self adapting echo cancellation equipment, 160MPIS DSP sound handling engine, 4 modulating channels, 2 paths for Digital to Audio Conversion, guarantees 16K sample rate, supports a wide range of 60-8000Hz audio frequencies, A/D. D/A signal to noise ratio up to 78, from 4 to 9 microphone input connections, double line input, line output, reduces radio interference and background noise.
·Internal input-output amplifier, suitable for variable sensitivity microphones, line level line input. Noise suppression up to 18dB, useful in noisy environments.
·Wireless echo cancellation, suitable for small-scale loudspeakers during high power overloads. Full duplex echo cancellation up to 52dB (1 Microphone), 65db (using additional AVMC200 fully directional microphone), Clear sound. Side tone cancellation 35dB.
·Convergence time <32ms, Echo neutralisation is greater than 100 milliseconds.
·Self adjusting step length wireless filter technology, continually studies and adapts to the changing acoustics of the environment, such as the speakers moving, the microphone or voice levels changing, or background noise. |
