The LH-115 provides the opportunity to perfectly record your voice recordings: Take your microphone signal and send it to the LH-115. With one or two headphones you now can now tap the signal and send it, unaltered, to you computer. From there again you can send another signal, background music for example, back to the mixer. Now you can speak sort of on the music and with the level control you are able to easily set the volume of the microphone signal. On your monitor signal you can thus hear the mix the way you prefer it for recording. And due to its small size, it's the ideal partner on the way.
