Because it is universal, meaning that it was developed to allow all kinds of hardware devices to connect to a computer with the same connection.

No. The built-in microphones on the Boss BR600 will not sound as good as a Behringer C1U USB condenser microphone. You should also note that there is no way to connect the C1U microphone to the BR600, as it requires a computer with a USB port to operate. If you want to improve the sound of the BR600, you will need to connect a microphone to the 1/4" inputs jacks using a microphone that has this connector, or an XLR to 1/4" adapter cable. Note that the BR600 does not have phantom power, so powering a condenser microphone like the Behringer C1 is not possible.
