4.5Power supply
Depending on your battery demand, the camera offers either a Gold Mount or a VLock adapter. You can change both yourself. For more information, see "Mounting and
unmounting the battery adapter", page 37). For further details, see our website or
ask your local ARRI Service Partner.
The camera accepts an input voltage range from 10.5 to 34 V DC. Do not supply
power outside the specified voltage range.
NOTICE
For maximum operation time, always use fully charged batteries with 10.5 to 34 V
DC (50 W minimum).
Always keep the BAT connector or attached battery accessible so that they can be
unplugged quickly in case of emergency.
4.5.1BAT in
NOTICE
If the power supply to BAT is interrupted with the camera switched on, the camera
will automatically repower and boot-up on reconnection.
Use the BAT connector, and a KC50-S or KC50-SP-S cable,
to supply the camera with 10.5 to 34 V DC. Do not use cables
longer than 4m.
4.5.2Powering auxiliary devices via the camera

4.6Camera Controls
The camera body has several buttons and switches to control the camera. They are
explained in detail in the following chapters.
4.6.1Audio control panel
1Audio function switch
2Audio display
3Left/right gain controls
4Audio SET jogwheel
4.6.2Operator panel
The operator panel consists of switches that offer quick adjustments to important
camera functions, such as exposure index or white balance.
For all switch positions (except ND positions), you can assign an individual preset.
See the next chapter for full instructions.
The EI and WB switches are assigned to exposure index and white balance
respectively. Permanent switch icons on the EI and WB soft buttons on the home
screen indicate this permanent assignment.
One of the functions FPS, SHUTTER, or LOOK can be assigned to the user switch
(US). A switch symbol appears on the home screen next to the soft button of the
assigned function.
You can only edit the value of the currently active switch position.
4Auto-white balance button
5Recording button & LED
26Camera parts and controls
4.6.2.1Operator switches
The EI switch (2) is dedicated to exposure index. WB (3) is dedicated to white balance
and ND (4) to filtering.
The US switch (1) can be assigned to control either FPS, SHUTTER, or LOOK. For
more information, see "Setting the user switch function", page 138.
The switches have three (US, EI, ND) or four positions (WB). Except for ND (4), you
can modify the switch position presets.
4.6.2.2AW auto white balance button
The AW button triggers the auto white balance functionality: based on the camera's
live image, AW calculates an automatic white balance and overwrites the active WB
settings. The result is also stored as the preset value of the active WB position and in
the first entry of the WB list.
AW triggering
► Note: Under or overexposed images may cause the auto white balance to fail.
Always trigger auto white balance with properly exposed images.
► To trigger an automatic white balance: press AW twice in a second (1).
Camera parts and controls27
► Two AW modes, Matrix and Center, are available.
Matrix mode: Full-image-based, the algorithm determines the image content
°
best suited to white balance calculation.
Use for regular image content.
Center mode: Calculates the white balance based on the center area of the
°
image.
Use with a gray card placed in the image center. For accurate results: fill the
entire area with the gray card.
The camera displays an image overlay showing the center area used for
calculation.
When you put your eye against the eyepiece, the proximity sensor (3) activates the
EVF (2).
You can configure the camera to show status information on the EVF (2).
When activated, the camera shows essential camera, audio, and recording
parameters next to the image.
You can modify/deactivate the status information via the EVF overlays and EVF statuscomponents menu. For more details, see "Status info", page 98.
Note: If surround view is active, the surround area is marked by a separating line or a
surround mask.
The infrared proximity sensor automatically deactivates the
viewfinder's internal OLED panel when you take your eye off it.
The sensor is placed either on the bottom left-hand side of the
viewfinder (generation 1, shown in image), or it is integrated into
the eye cup (generation 2, not shown).
Note: To avoid hardware damage, always keep the proximity
sensor unobstructed.
