Product Introduction
Specifications and parameters of the frequency shifting device for the conference system
OBT-2200 is a digital anti-noise system device specifically designed for use in meetings, speeches, teaching, and stage performances, and it can effectively suppress noise.
Increase the volume to ensure the transmission quality of the voice, with high fidelity and clear sound. Even in poor environmental conditions, it can significantly suppress echoes.
Can effectively prevent the audio equipment and speakers from being damaged.
It is equipped with a six-channel phantom power supply for microphone balanced input, as well as a system connection port, dual-channel input and output interfaces.
Depending on the requirements, it can be expanded and connected to form a large-scale anti-noise conference system.
Technical Specifications:
Output voltage: Output phantom 48V;
Power supply method: AC 220V - 230V, 50/60Hz;
