Hi,
I'm assuming that this unit is not a power source, but rather that this is the necessary resistance circuit for supplying phantom to the mic from a 48V rail supplied by a console. Is this the case? If that is true, then what power source is the mic itself designed to use to charge its capacitors (without this unit)?

Answer:
The power module attached to some condenser microphones provides several important functions. First, it converts the 11 – 52 VDC phantom power into a smaller DC bias voltage used to power the FET impedance matching circuit inside the microphone. Also, it provides low frequency roll off and converts the signal to the proper impedance and balances the output. The power module is a necessary component. Microphones that use this power module are fixed-charge back plate, permanently polarized condenser.

I cannot find any manual or spec for this.
I want to understand the slide switch functions and if this can be used on amps that do not have phantom power.

Answer:
Thank you for your inquiry. This is a phantom power only in-line power module and is furnished with U853R, U857R, PRO35. The power module attached to some condenser microphones provides several important functions. First, it converts the 11 – 52 VDC phantom power into a smaller DC bias voltage used to power the FET impedance matching circuit inside the microphone. Also, it provides low frequency roll off, converts the signal to the proper impedance and balances the output. The power module is a necessary component.
The switch is referred to as a low-cut filter, bass roll off, low-requency roll off or a high-pass filter. This switch enables internal circuitry that filters frequencies from the audio signal below the specified frequency. Enabling this switch can help filter out sounds in the low frequency range such as HVAC rumbles and certain wind sounds (in an outdoor application). Please note this filter does not completely cut all low frequencies. The straight line means that nothing is being filtered; the bent line means the filters are enabled.
