The perfect solution to any situation in which you need to cleanly boost a microphone signal before the preamp * Adds up to +25dB of perfectly transparent gain to your signal, giving low-output mics a major boost which can make even budget microphones sound clean and professional * Ideal for use with any ribbon mic, since it changes the phantom power that can hurt them into the extra gain they require * Provides long cable runs with enough energy to ward off noise * Excellent for acoustic guitars with XLR outputs, giving them an immediate dose of extra gain that prevents noise from infiltrating your sound
