Most interfaces, including all PreSonus interfaces only send 48V out through the XLR stage of the preamp, so if you are using a quarter-inch connection to the condenser, this will not work. If you do not turn on 48V when using a condenser mic, you will receive little-to-none signal. Note: A common mistake is to not turn on 48V "Phantom Power" when using a condenser microphone.

Make sure that the source you are using, such as a mic, guitar, keyboard, etc., matches the type of input you are plugging it into on your interface. For instance, the AudioBox 44VSL device contains mic, instrument, and line-level inputs because a line-level input requires a much stronger signal input than what a guitar could produce, plugging in a passive electric guitar to a line-level input would result in an extremely low recording. The first question to ask is: what are you recording? You'll want to make sure you are inputting the right type of signal into the right type of input.

Q: Why is my recorded signal too low or quiet?Ī: If you are recording a signal with your PreSonus audio interface and receive a recording that is too low or quiet sounding, please follow this guide to troubleshoot this particular issue.
