500 Mic Pre two

Mic / Line Preamp module in the 500-series format.




    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.
    Some of the highlights of the 500 MicPre two :
    * Mic / Line Preamp modules
    * Discrete transistor front end
    * Balanced input and output
    * Gain Range from -10 dB to 60 dB
    * Separate Hi-Z input (on front panel) with gain control
    * 80 Hz switchable hi-pass filter
    * Phantom Power switch
    * Phase Reverse switch
    * Fits any 500-series rack or console
    * Designed by Malcolm Toft
    * Hand-crafted and hand-wired by Ocean Audio in the UK
