ART PRO MPA
User Guide

APPLICATIONS
Microphone Preamp The main application of the PRO MPA is a microphone preamplifier. Plug any microphone directly into either input and set the input and output controls to provide an appropriate level into the next stage of your system. DI (Direct Input) The PRO MPA is ideal for use as a DI box. Plug the instrument into either input and use the XLR or 1/4 (or both) outputs to connect to your recorder, board or PA system. Experiment with different Input Level settings for different textures. Mastering (2-mix processing) Because of its low noise and excellent tonal qualities, the PRO MPA is ideal for running mixes through before recording to DAT or cassette. Used as a mastering device, the PRO MPA is capable of adding warmth and, if set properly, gentle tube compression to the incoming signal. Low noise and variable Input and Output level controls make the PRO MPA ideal for level matching material in post production situations. Special Effects For industrial, metal, or just �flavor� textures, experiment with the PRO MPA. Cascading the channels can produce overdrive and tube distortion that can add interesting textures when blended with vocals and different instruments. Placing signals purposely out of phase can yield interesting results. No harm will come to the PRO MPA with this type of experimentation. However, be sure to have output and monitoring levels turned DOWN before �testing� the sound. When running one channel into another (cascading), you have the potential for upwards to 120 to 140dB of gain.
