Often placed in close proximity to components such as the power supply and processors, internal sound cards or integrated audio systems can generate audible noise. Combined with the fact that computers are often used in high noise level environments, the performance of peripherals like microphones, headsets, and speakers may be affected.
Both our USB-SA Premium External USB Sound Card and our USB-MA Premium External USB Microphone Sound Card, bypass the computer’s built-in sound system, converting the analog signal to digital. The result is superior low-noise audio. The USB-SA has both a stereo microphone input and a stereo speaker output, while the USB-MA has only a stereo microphone input.
