The OBT-2200 is a digital anti-howling system device for conferences, lectures, teaching, and stage.

Can effectively suppress howling;

Extended volume

Guarantee the transmission quality of voice, high fidelity and clear sound. Even in the case of poor environment, it can greatly suppress the whistling;

Can effectively prevent burning of audio equipment and speakers;

The OBT-2200 is equipped with a six-way phantom-powered microphone balanced input, as well as a system port, two-channel input and output connectors. As needed, you can expand the series into a large anti-howling conference system.
