The AXAGON ADA-71 SOUNDbox external 7.1-channel USB sound card extends the PC with surround sound and a host of audio inputs and outputs.

It allows you to connect 7.1, 5.1, 4.0, 2.1 or 2.0 stereo speakers as well as stereo headphones or stereo microphones.

In addition, it includes both analog line-in and digital optical and coaxial inputs for recording an external signal from music instruments or DVD players. The digital optical or coaxial output then allows you to connect to the amplifier.

Using sophisticated Xear 3D software, you can fine tune surround effects, equalizer, or Karaoke effects.
