The 500 MicPre two is a Mic / Line Preamp module.
It has a huge gain range from -10 dB to 60 dB.
The separate Hi-Z input on the front panel allows you to directly plug-in a guitar or keyboard, and / or use this unit as a DI-box.
Phantom Power and Phase Reverse switch are pretty standard on most Preamps, but this unit also has a 80 Hz hi-pass filter.
