Make sure that the speakers that you use near a CRT computer monitor are
shielded speakers. If your monitor begins to become discolored in one of the
corners, or if the image appears warped, this could be due to unshielded
speakers and you should move the speaker further away to avoid damage to
your monitor.
Line and Mic In
The Revolution 7.1 has a stereo line input. This input allows you to record CDs,
audio from videos, instruments, or virtually anything else with audiophile-quality,
24-bit/96kHz sampling. It also has a microphone input. This input is mono (one
channel) and has a gain and impedance designed to accommodate the output
of a microphone. It can accept a small mono condenser microphone and it also
provides power for common electret multimedia microphones. You can connect
a small microphone for recording sound effects, voice-recognition, and video
conference applications.
You can set the Input level of the Line and Mic inputs on the Input/Other tab of the
Revolution 7.1 control panel. See the Control Panel section for more details.
