Audio Technica ATR 2100 Internal vs. External Preamp


This video demonstrates the massive benefits of using an external interface with solid preamps over the cheap built in preamp that you find in a USB plug and play microphone. In this case, the microphone happens to have both a USB connection and an XLR jack, so I went ahead and used the exact same microphone — an ATR2100 — to let you hear the difference a preamp can make.
