Quick Guide
Thank you for choosing the NAJA A301 array microphone. This
guide will take you through the use of this product.
1.Product Introduction
1.
The NAJA A301 is an array microphone which consists
of 6 silicon microphones and uses unique digital signal
processing algorithms: echo cancellation (AEC), noise
cancellation (ANC), beamforming (BF), and reverb
(De-reverb) to ensure that occupants can move around
the space while still achieving high-quality sound.
2.
Noise cancellation: effectively suppresses
environmental noises. Within the pickup radius, the
occupants can move freely, standing, sitting and other
movements, that does not affect the sound quality.
3.
This device is suitable for sound processing with
multiple pickup sources (Maximum pickup distance is 5
meters) with interactive occupants. Will obtain high
quality pickup and high-quality interactive echo
cancellation as a result.
4.
This product is plug and play with no parameters to
