LECTROSONIC DIGITAL TELEPHONE HYBRID

The Lectrosonics DMTH4 is a versatile 3-input, 24-output matrix mixer designed to seamlessly integrate non-traditional audio sources like telephone lines and video codecs into the advanced digital bus structure of DM Series processors. Ideal for sound reinforcement applications, teleconferencing, boardrooms, and worship centers, this unit tackles the echo problems inherent in teleconferencing by using sophisticated acoustic echo cancellation. The dynamic architecture not only simulates mic or line inputs but also provides digital signal processing on both input and output channels with advanced features like filtering and compression. Boasting extensive control capabilities through intuitive USB and RS-232 interfaces, the DMTH4 ensures straightforward setup and remote control, perfect for large, complex audio systems.
