The audio powering switch from DCN multimedia is responsible for routing, controlling and processing the audio and supplies power to the multimedia devices. The elegant contrast between the glossy black front and the matte silver handles reflects both functional and modern design. An intelligent adaptive acoustic feedback suppressor, echo cancellation and two 5-band parametric equalizers ensure optimal speech intelligibility. Furthermore the device has two audio inputs for inserting external analog audio signals and mix-minus is also provided for connecting the DCN multimedia system to (video) conferencing equipment.
