2 ND Filters
Your URSA Mini has three internal neutral density filters. Together with a clear filter, the
available settings are ‘2,’ ‘4’ and ‘6’ stops. These filters allow you to reduce the amount
of light reaching your URSA Mini’s sensor by a preset number of exposure 'stops'.
By reducing the exposure, you can continue shooting at wide apertures in bright
conditions such as outdoors on sunny days.
To adjust your neutral density setting, rotate the wheel upwards or downwards.
The 'clear' setting means there is no ND filter being used. From settings 2 to 4, the
ND filters gradually increase in density so you can decrease light if you need to.
Because different people prefer to use different terms for each ND filter, the
measurement of your ND settings can be customized in the LCD menu. You can identify
the ND filter number, amount of stops in light reduction, or the fraction representing the
amount of light reduced for the filters to suit your preference.

3 Settings Wheel
Set this wheel's function by adjusting the adjacent three position switch next to the
wheel. The options are ‘headphone,’ ‘monitor’ and 'iris'.
‚
Headphone
When set to 'headphone', the settings wheel will adjust headphone audio levels.
Rotate the wheel upwards to increase volume, and downwards to decrease.
‚
Monitor
When set to 'monitor', the settings wheel adjusts audio levels on your URSA
Mini Pro 4.6K’s built in monitor speaker. The speaker is located on the outside of the
LCD monitor door and can be used to monitor audio without headphones. Rotate
the wheel upwards to increase volume, and downwards to decrease. This function
is disabled while recording from the camera's internal microphone to prevent
unwanted feedback.
‚
Iris
When set to 'iris', the settings wheel is used to adjust the aperture of compatible lenses
mounted to your URSA Mini Pro 4.6K. Rotating the wheel downwards opens the iris,
and turning the wheel upwards closes the iris. These directions mimic the operation of
aperture on adjustable still and cinema lenses.
TIP To change aperture settings via the settings wheel, URSA Mini Pro 4.6K
must be fitted with a lens that supports changing aperture via the camera.
If you are using a B4 or PL lens connected via the broadcast 12 pin connector,
make sure that the lens iris switch on the handgrip is set to ‘A’ or 'auto'.
