If renting this, also consider:

o low echo
o moderate working reach

straight talk:
The AT4041 is a good fishpole mic for tight interior shots.  It has good rejection at the sides to reduce room echoes.

The 4041 is very sensitive to voltage drops from phantom power supplies.  When powered by the Shure FP32 field mixer, be sure to listen closely for increased hiss as the FP32's 9-volt battery supplying power to the mic is consumed.

The 4041 is sensitive to wind noise and benefits from being placed within either a softie or windscreen.

grip tips:
As a boom operator, listen very carefully.  You need only drift a small degree away from an actor to lose the sound coming directly her mouth and to pick up her voice echoing off surrounding surfaces.

Generally, the low-cut filter should always be on when recording dialogue to reduce low-frequency noise like footsteps and environmental pollution.  The human voice does not extend into the area affected by the low-cut filter.
