    Just because you have an eye for a bargain doesn’t mean you have to sacrifice desktop style. The economical ServSwitch Spectra™ from Black Box combines a sleek, space-saving design with the dependability you’ve come to expect from the ServSwitch™ line of KVM switches.

    With the ServSwitch Spectra, you can control two PS/2® computers with one keyboard, monitor, and mouse. Just use keyboard commands or the simple push button to switch effortlessly between PCs.

    You'll find installing the ServSwitch Spectra is effortless as well. Simply connect your keyboard, monitor, and mouse to the ServSwitch Spectra with the attached cables. Then attach the ServSwitch Spectra to your PCs with our CPU cables. You can use the standard CPU cables for lower resolutions and distances up to 15 feet. Or use coax cable for higher resolutions and distances up to 20 feet.

    Once you’ve connected the cables, turn on your computers and you’re ready to go! No additional hardware or software is necessary. Plus, the ServSwitch Spectra is interface powered, so you don't need a power supply either.

    But what about the lockups that can occur with ordinary KVM switches? Most KVM switches can’t maintain synchronization between your PC and the keyboard and mouse. The result: Your computer freezes and you have to reboot. The ServSwitch Spectra, however, provides full keyboard and mouse emulation, enabling you to switch between PCs without any delays.

    Besides full keyboard and mouse emulation, the ServSwitch Spectra supports video resolution up to 1600 x 1280 and stereo audio. To use the audio capabilities of the ServSwitch Spectra, attach your PC to the ServSwitch Spectra with audio cables (as well as the CPU cables) and plug your favorite speakers into the ServSwitch Spectra.

    And as proof that sometimes you can judge a book by its cover, all these features come packaged in a sleek, stylish switch designed to save space and complement your office decor. So if you want to maximize time and space without sacrificing style or money, choose the ServSwitch Spectra.
