The TRULINK 4-Port DVI and PS/2 KVM Switch with Audio allows you to control four computers with one monitor, keyboard, and PS/2 mouse console. The audio function enables a single microphone to provide audio input to each of the computers. In addition, you can listen to the audio output of each computer on a single set of speakers. There is no better way to save time and money than with a TRULINK 4-Port DVI and PS/2 KVM. Since a single console manages all of the computers, the TRULINK KVM eliminates the expense of having to purchase separate console components for each computer.
