Overview
The LDV-204AUSK is a 4-port DVI USB KVM Switch with Audio and Microphone switching function. It allows you to control 4 USB-enabled multimedia computers with DVI video interfaces, using only one USB keyboard, USB mouse, monitor and a set of speakers and microphone. You can select the computers and USB device hub ports and audio/mic channels either simultaneously or independently, using either front-panel buttons or keyboard hotkeys. This DVI USB KVM Switch adopts the DVI interface technology that implements genuinely digital signal transmission over the cable to reduce undesired distortion from conventional analog/digital conversion.

Audio & Microphone Switching offers uninterrupted multimedia experience with KVM Switching
The audio and microphone switching function allows you to leverage the multimedia systems on each of your multiple computers. You can monitor the audio/mic input/output of each of your computers without plugging on and off the audio/mic cables.
