TD1220

Intelligent anti-howling processor

TD1220 is a digital anti-howling system equipment dedicated for conferences, lectures, teaching, and stages. ●Can effectively suppress howling; ●Extended volume; ●Ensure the quality of voice transmission, with high fidelity and clear sound. Even in poor environments, reverberation can be suppressed to the greatest extent; ●Can effectively prevent audio equipment and speakers from burning out; TD1220 is equipped with six phantom-powered balanced microphone inputs, a system connector, and two-channel input and output interfaces. According to needs, it can be expanded in series to form a large-scale anti-howling conference system.
