In the past, many PC users have been frustrated with the poor audio performance typical of sound cards. Even cards that use good components and circuit-board design techniques are not immune from the noise sources found in the typical PC. Complaints range from pop and clicks associated with hard disk drive head movements to high-pitched tones from a graphics card, disk controller, or other high-speed digital logic.

Tango24, along with an ADAT digital I/O card such as Dakota or WaveCenter, eliminates these problems and lets you concentrate on what's important: your audio! By optically isolating the audio A/D and D/A converters from the PC chassis, and by powering the sensitive analog circuitry with a separate power supply, Tango24's 24-bit A/D's and D/A's won't be undermined by noise and hash coming from a computer that was never meant to be kind to sensitive audio signals.

Another advantage is that with the ADAT optical lightpipe, you can locate your converters up to 10 meters (33 ft) from the computer. Other products limit you to just a few feet of cable, making studio setup inconvenient, and not providing enough distance from the fan noise produced by your computer.
