2 TRINITY 2 camera setup quick guide
Foreword
ADVICE
Only a precisely executed camera preparation will enable you to get the TRINITY 2 system in perfect
SYMMETRY and NEUTRAL BALANCE.
Balance Strategy
The camera preparation must meet the following requirements:
ADVICE
Compact length and low Center Of Gravity (COG)
Keep the COG (centre of gravity) of the TRINITY 2 head as low as possible and the overall
length of the camera setup should be as compact as possible.
If the camera length is unnecessarily long, the COG / hight of the Tilt axis of the TRINITY 2 head
could be quite high, which will force you to extend the Center Post to compensate for top weight.
As the Center Post lengthens the more extreme the degree of inertia will be and will reduce the
agility of the TRINITY 2.
When using an ALEXA 35 or ALEXA Mini LF, Signature Prime lenses or a zoom lens keeps the
camera setup at an optimal length.
If the ARRI ALEXA LF or AMIRA is being used a Prime Lens will be required.
Most box-type television cameras with a zoom lens do have the right length for use with the
TRINITY 2 system.
Video Transmitters should be mounted to the rear Battery Hanger.
This uses the weight of the transmitter as a counterweight and the total weight of the system can
be kept low.
Camera Preparation
The camera preparation must meet the following requirements:
ADVICE
Camera components and accessories mounted on the camera must be attached symmetrically
and matched to each other.
If two focus motors are needed, use two 15mm rods (equal length and same material) and mount
them on the top of the camera.
Now place one focus motor on each rod.
Make sure that the gears are facing the front of the lens and the motor housing of the camera
body.
If only one focus motor is required, then two rods are also required.
Place the focus motors vertical above the lens.

TRINITY 2 camera setup quick guide 9
Secure component and accessory attachment
ADVICE
Make sure that all components of the camera and accessories in the setup are fully tightened.
Ensure that none of the components are loose or have any play to avoid vibration and any
performance issues.
Camera Dovetail Plates
Using the SAM plates will speed up the camera setup and later the balancing
process.
The special hight of every SAM plate will lift the dedicated camera right into the
center of the TRINITY 2 inner ring.
This way a perfect COG of the camera is guaranteed.

Installation of the camera in the TRINITY 2 head
Placing the camera
► Gently slide the camera into the ring from either the front or back.
► Bring the camera as close as possible to its center of gravity.
► Lock the dovetail clamp mechanism.
► Assemble all required accessories such as focus motors, transmit-
ters, connect all required cables such as camera power and video
cables.
Connecting the Ring Main Camera
► Plug in the Ring Main Cable.
► Take the part of the cable that is plugged into the inner ring and
attach it with a bongo tie to the back of the camera or to the rear
bracket of the ALEXA 35 / Mini LF.
COG / Fore and aft adjustment
► Open the Tilt-Lock.
► Move the camera forth and back until it reaches its
center of gravity.

TRINITY 2 camera setup quick guide 12
Locking Clamp Lever
► After the camera has reached the desired position / COG, push
the clamp lever all the way to the right until the dovetail clamp
mechanism is securely locked.
Checking the current height
of the tilt axis
► Slowly and carefully tilt the rear of the camera until the bottom cor-
ner of the camera approaches the top cover of the TRINITY head.
Minimum height of the tilt axis
► To ensure enough clearance for the ring main cable, which is lo-
cated on the back of the camera, a
minimum distance of approx. 25mm/1in be available.
Height Adjustment Clamps
► Open the four wing clamp screws and raise the
complete tilt together with your assistant.
► Make sure the small notch on all 4 rod clamps is
exactly on the same line!
► Once the desired position has been reached, tighten all four wing
clamp screws.

Power up the TRINITY 2 Battery Hanger
ADVICE
Powering TRINITY 2 Head, Top and Bottom Stage at the same time
This would cause more than the allowed amount of volts to flow through the
ARTEMIS 2 and TRINITY 2. Risk of damage to the accessories.
Only use the Top Stage TST-2 in combination with the Battery Hanger Module BHM-2 for the
internal power supply of the TRINITY 2 Head.
Alternatively, an external power source can be used to power the TRINITY 2 head.
DO NOT combine the internal with an external power supply!
Main Power Battery Hanger
► To turn the BHM-2 / the entire system ON and OFF, press and
hold down the Jog-Wheel until the ARRI logo appears on the dis-
play.
Power up the RCP-3
Main Power RCP-3
► To turn the RCP-3 ON and OFF, press and hold down the Jog-
Wheel until the ARRI logo appears on the
display.
► Ensure that the TRINITY Mode is aktive and Follow Mode is
OFF.

Center the Camera
► Move the camera to a neutral position in both the Tilt
and Roll axis.
Power up the TRINITY 2 Head Main Power
Main Power ON
► Bring the MAIN switcher into the ON position.
ATTENTION
After switching on, the TRINITY-2 head is supplied with 24V, camera, monitor, accessories are
supplied with 12V and 24V, depending on the case.
The motors are not yet active as long as the Stabilizer is set to OFF.
As long as the Stabilizer is OFF, you can work on the camera setting.

TRINITY 2 balance quick guide 17
Power up the TRINITY 2 Stabilization
CAUTION
Automatically move to the home position
Risk of crushing fingers. The camera / tilt and roll axis will automatically move to the home
position, after turning on the stabilization.
Make sure that your fingers do not get between the top cover and the camera while checking the
tilt axis.
Stabilizer ON
► Turn the Stabilizer ON, when the camera preparation is complete.
Global Home Position / Display
►Home is displayed in the small display.
►Press the Jog-Wheel to move the Tilt and Roll axis in
the neutral Home position.
► Observe that the TILT and ROLL axis have automatical-
ly moved to the global / absolute zero position.

TRINITY 2 balance quick guide 18
Neutral Horizontal Balance
► Bring the entire rig slowly into a horizontal position.
► Make sure that none of the cables, brackets or other accessories are blocking the movement of
the TRINITY head.
► Move the Gimbal in the desired position.
► Telescope the center post and use the Fine Trim adjustment until you reach
the neutral horizontal position and don't feel any drop down.

TRINITY 2 balance quick guide 19
Vertical Balance
After the center of gravity COG of the camera has been set in the TRINITY 2
head, the camera is the reference for the following
adjustment.
Do not move the camera fore or aft from the previously
determined neutral position! (COG)
Fore and Aft
► Bring the TRINITY Rig back into the vertical position.
► Open the 19mm rod clamp at the battery hanger and move the en-
tire assemble (rods, batteries and the RCP-3) fore or aft till the en-
tire rig reaches a
neutral vertical position.
Check Fore and Aft
► To verify that the entire system is neutral in the vertical axis, check
that the post is in a line with the stand.

TRINITY 2 balance quick guide 20
Side to Side Balance
After the Top Stage and the Pendulum had been centered, the
Battery Hanger is now the reference for the side to side adjustment.
Do not move the Top Stage or the Pendulum out the
previously determined neutral centerposition!
► Now a sideways movement becomes visible.
► To bring the entire rig into a vertical position, the camera inside
the ring needs a side to side
adjustment.
Side to Side Lock
► Open the side locking mechanism by pushing the clamp lever to
the left.
