Signal Processing Circuit

Noise reduction processing circuit, automatic gain control circuit, echo cancellation

Protect circuitry

8KV Air contact ESD, lightning strike protection, reverse polarity protection circuit

Remote echo cancellation

Echo delay handling capacity : 256ms, Echo suppression ratio : >60dB

Ambient Noise Cancellation

Automatically suppress room noise and improve sound intelligibility;  Noise reduction capabilities : 0~40 optional

Automatic gain control (AGC)

Automatic gain control (automatic gain control) makes the gain of the amplification circuit automatically adjust with the signal strength of the automatic control method, that is, to optimize the sound difference due to the different distance from the speaker, and has an anti-breaking function; AGC range: -24dB to -5.5dB

Cascading function

An additional pickup (line in input) can be cascaded to expand the pickup range.The mixing output of the two pickups allow you to expand the pickup range without affecting fidelity, remote echo cancellation and other functions.

Line-in Function

Support 3-way Line-in input to meet the teaching courseware, wireless microphone, musical instrument input at the same time;

Anti-reverberation technology

When a wireless microphone, courseware or musical instrument is input and played through local and remote speakers, the anti-reverberation function is turned on, and the sound is clear and natural without muddy.

Recording Backup (All audio sources)

With independent audio output for dual-talk recording backup
