If you connect the output of a sound card directly to a guitar amplifier without using a reamp box, you may encounter several issues:
1. Impedance Mismatch: The output of a sound card is designed to drive a line-level input, which typically has an impedance of around 10k ohms or higher. A guitar amplifier input, on the other hand, has an impedance of around 1M ohm. This means that the sound card output will not be properly loaded by the amplifier input, which can result in a loss of high-end frequencies and a change in the tone of the signal.
2. Signal Level: The output of a sound card is typically much higher than the output of a guitar or bass, which means that it can overload the input of the amplifier and cause distortion or clipping. This can damage the amplifier or speakers if the levels are too high.
3. Ground Loops: Connecting the output of a sound card directly to a guitar amplifier can also create ground loops, which can result in hum or noise in the signal. This is because the sound card and the amplifier may have different ground potentials, which can create a voltage difference between them.
Using a reamp box helps to avoid these issues by matching the impedance of the sound card output to the impedance of the amplifier input, reducing the signal level to a suitable level, and eliminating ground loops.
